wd40efrx cmr or smr

This is the revision of firmware that came on both of our drives. Just read this bollocks: https://arstechnica.com/gadgets/2020/06/western-digitals-smr-disks-arent-great-but-theyre-not-garbage/2/. At least WD is now showing which model numbers are CMR or SMR on their spec. Initially it worked reasonably fast, but as time went on, it slowed down. Next, we will move on to the tests focused on the WD40EFAX and NAS RAID arrays. Please, participate and enjoy! Shipping only, not available in most stores. I know I’m being a d!ck here but the video has a much more thorough impact assessment while this is more showing the testing behind what’s being said in the video. In the case of my network (a university research laboratory) it means I can drop a bunch of other stuff on desktop systems installed to cache network reads and mitigate head seek thrashing on the fileservers which drops power consumption further, but more importantly drops the purchase costs AND administrative complexity setting the things up. During this time, scrubs were disabled for the pool and resilvering priority was completely disabled. sorry i was copy pasting hence the mistake. ウエスタンデジタルのプレスリリース(2019年12月24日 11時20分)ウエスタンデジタル、世界初の20tb smrと18tb cmr hddのサンプル出荷を開始 2) For backup purposes SMR HDD and QLC SSD is a good choice. Plus, I’d like to see some stock hardware RAID devices tested along the same lines. WD Red = CMR, WD Pink = SMR. Would be interesting to test on consumer devices such as Synology or QNAP ? CONCLUSION: one more checkbox to check when buying drives, not SMR? or Toshiba N300 would be the next alternatives? But for a consumer case is the whole SMR debate a real problem? sorry i was copy pasting hence the mistake. The WD40EFAX is demonstrably a worse drive than the CMR based WD40EFRX, and assuming that you have a choice in your purchase the CMR drive is the superior product. SMR drive support is getting better when hosts know they are using SMR drives. When that NAS readiness was put to the test the drive performed spectacularly badly. Even down to external drives needing to be marked in this way. I’m also happy to see you tried on a second drive. (BTW, if you ask WD how to know the DRIVE MODEL inside an external WD enclosure, they will tell you it’s impossible!!! The problem now is that SMR are firmly embedded and they are here to stay. Using older WD Reds in a server with ZFS raid, and thinking about buying more on sale… big eye opener here. HGST fyi got bought out by Western Digital. Stupid WD support… ). The drives are Seagate Barracuda ST500LM050 drives from the same or similar batch. That’s terrible practice. More worryingly the larger Ironwolfs have 256MB cache and that's normally an indicator of "SMR under the hood", so Seagate may be in the process of switching these over to DM-SMR too and just not gotten to 4TB yet. I passed this article around our office. So glad I got 12TB Toshibaa N300’s last year that are CMR. In read tests the SMR drive performs fairly similarly to the CMR based WD40EFRX. Will has worked in both big enterprise and small business IT since 2001. This is a a great article. Not talking about it is a bigger issue even if I could see myself accepting 10-20% of the drive was SMR. They go way too in-depth on the technical side, but when you’re looking at it, they did a less good experiment. I have a problem with your RAIDZ test: normally I replace failed disks with brand new, just unpacked ones, not the ones that were used to write a lot of data and immediately disconnected. All I can conclude is “don’t replace failed disks in RAIDZ arrays with SMR disks that just came out of heavy load and did not have time to flush their cache. While all three CMR drives comfortably completed the resilver in under 17 hours, the SMR drive took nearly 230 hours to perform an identical task. Now I know I’ve sold my customers FreeNAS hardware that isn’t good. I didn’t specifically checked for it back then because, you know, N300 series. STH articles have always had the feel of ‘real news’ to me–from the easystore article to this one, highlighting the true pros and cons. Still, it is a good step. As a perpetual dabbler, he is always open to new solutions for old problems. That is not a recipe for success. Thank you for the article and thank you in particular Will for the link to the WD Product brief. (*)"Jumping off territory" when SSDs hit about 4-5 times the price of the equivalent HDD, then it's time to look at changing what you buy. perhaps hardware raid or Linux mdadm etc, instead of just ZFS. While I expect the drive failures, I also look for a predictable level of performance during operation and rebuilds. In PCMark8, the WD40EFAX manages to outperform the CMR WD40EFRX. June 2, 2020, 1:29pm #11. (1) WDC WD20EARX-00PASB0 : 2000,3 GB [1/0/0, sa1] – wd Due to the nature of our last test, it was not performed in rapid succession with the previous two. The differences between SMR and CMR are fairly nuanced where regular STH readers may understand, but those regular readers are the same IT professionals that keep up on the latest technology trends in the market. Background: SMR/CMR: CMR: CMR: 3.5" 8TB and above: CMR: CMR--CMR: Nonetheless, it has now followed up with a complete list of SMR models that should certainly help alleviate concerns and make it … Western Digital, Seagate et Toshiba (pour ne citer qu’eux) proposent une large gamme de disques durs et ils utilisent tous les technologies SMR et PMR (également appelé CMR pour Classic Magnetic Recording).Malheureusement pour nous, aucun d’entre eux n’indique clairement quelle technologie ils utilisent dans les disques durs orientés NAS… mais les choses … I needed 3 x 10TB drives, I went with barely used open-box HSGT He10 on eBay (all 2019 models with around 1,000 hours usage). I’m fine with the drive makers selling SMR drives. I generally tell people RAID arrays tend to operate at the speed of their slowest part. 筆者先前曾撰文說明,WD證實自家的Red(紅標)系列硬碟採用SMR(Shingled Magnetic Recording,疊瓦式磁記錄)技術,而WD也加碼自行揭露各系列2.5吋與3.5吋硬碟使用的儲存技術,讓消費者能在購買前做為參考。 We do want to point out that we likely want to see a more rigorous drive certification process at iXsystems, but also that they at least have done a good job communicating it on their blog. I’m really frustrated. WTF is that??? So if later when qts hero comes out and your WD RED NAS (WD40EFRX) keeps dropping out, this is why. Do I need an expensive CMR (Ironwolf Helium), a “cheaper” SMR Red NAS drive or will a standard barracuda 8TB SMR “Archive Drive suffice”, for Media (Plex) and Photos. Western Digital Red 4 TB 3.5-Inch SATA 6GB/s NAS Hard Drive (WD40EFRX) 4.4 out of 5 stars 6,890. It is strange not to at least generate some workload during a rebuild. Since my source had 4 x 4TB WD Red CMRs, using a single 8TB drive for backups was perfect. If your drive is not found in this guide, please send me pictures from both, the label and the PCB sides of the HDD (or full model and serial number if you cannot take the pictures) and I'll … I just want a clear demarcation. Save my name, email, and website in this browser for the next time I comment. 1) For higher NAS use stay away from SMR HDD, and QLC SSD’s. In these kinds of shorter burst activity workloads, one can see how SMR may be used as a substitute. We are using a third party service to manage subscriptions so you can unsubscribe at any time. I commented at the time it allowed them to finally merge that it was likely that China saw SSds as providing sufficient competition to keep the HDD makers honest - and I think I've been proven right. I wanted to share an overview of our DMSMR architecture, and how we apply specific capabilities and configurations. Haven't had any major issues but I'm pretty sure this has happened to me before. I am running a 6×2.5″ 500GB RAID10 array for a total of 3TB for my Steam library. How often do you force your marathon runners to run sprints just after they’ve finished the marathon? We are going to start with some general benchmarks to try and place the WD Red (WD40EFAX) performance in a larger context. The SMR drive has a much larger cache than the CMR version, 256MB vs 64MB, which perhaps helps account for the win here. Even with a cache flush they’re hitting steady state because of the rebuild. Anybody who are familiar with raid and zfs, probably would not have bought it had they known they were SMR hdds. It’s about time a large highly regarded site stepped in by doing more than just covering what Chris did. The WD40EFAX is the only SMR drive in the comparison and is the focus of the testing. They’re using different size drives, more drives, they’re not putting a workload and just letting it rebuild. Why keep SMR and PMR drives with the SAME capacity in the same line and HIDING this info from customers? And they (WD) know it, hence why the hush hush. We found SMR can put data at risk 13-16x longer than CMR. If you are reading this piece, and know someone who uses, or may use WD Red drives in NAS arrays but may not keep track of trends, send them this article, a chart from it, or the video. there is no edit, so i may have to delete and repost. Device-Managed Shingled Magnetic Recording (DMSMR) technology is different from Conventional Magnetic Recording (CMR), and can be implemented in various ways. As Micron point out: The average large HDD is write once read mostly and the 0.2-0.8DWPD profile of the IONs is a good fit for a lot of applicatons. Now we’re going to switch to Seagate. western digital, Seagate, or Toshiba. More on this topic here https://forum.qnap.com/viewtopic.php?f=45&t=154346, And detailed info on why SMR sucks https://blocksandfiles.com/2020/04/15/shingled-drives-have-non-shingled-zones-for-caching-writes/, this only affects WD##EFAX models; (EFRX are unaffected). IIRC the seagate SMR was something like 80GB SMR, 20GB CMR, 80GB SMR, 20GB CMR and that was still too much for normal multi-tasking use of the drive. +1 on rep for it. We did not experience this failure mode, and instead only received extremely poor performance. https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/product/internal-drives/wd-red-hdd/data-sheet-western-digital-wd-red-hdd-2879-800002.pdf. Yes, there is an array running here, due to the brilliance of picking drives from different production runs and vendors, that has half SMR and half CMR. CMR was tested in the same way so I don’t see how its a bad test. Things get worse when Steam needs to preallocate storage space for new games, often I have to leave the machine alone for two to three hours. Friends don’t let friends use SMR drives for NAS. That’s for sure! Impossible to replace a disk in a RAID5 array, the controller would eventually fail the rebuild. You don’t test a drive before putting it into a rebuild scenario? Why is that? CMOSTTL this basically shows stay away from SMR even for backup in NASes. There @Patrick is saying how much he loves WD Red (CMR) drives while using this to show why he doesn’t like the SMR drives. The systems and capacities used will impact results in different ways. Still, the WD Red line reaches well beyond the iXsystems blog audience and even to local retail channels where these drives may be purchased without the benefit of online research. We had two main areas of testing. Gladly, i checked my WD ELEMENTS drives, a NONE of the internal drives is PLAGUED by SMR! They wrote the article like someone who uses ZFS though. Without LVM file systems, just plain MD-RAID single file system. corrected thx hey thanks for the quick reply! If so, this is the best deal for a … We have maybe 200 CMR Reds that we’ve bought over the last year. Great article as always. I am looking to create a Plex Media Server for music, videos, tv shows, photos, etc. You will regret it later if you care about your RAIDset and the drive speed will drop to less than 5MB/second maximum in the process). A great example is http://blog.robiii.nl/2020/04/wd-red-nas-drives-use-smr-and-im-not.html. Brand-new never used 4TB Western Digital NAS Drive WD40EFRX 3.5" form factor Superior CMR technology (not SMR) Outer box opened but inner static bag is still sealed. The reason being simply that whilst SSDs are more expensive, the power savings and better seek times usually make up for it over the lifespan of the equipment. Thanks for testing and reporting! thats it afaik. I was under the misapprehension (along with that sinking feeling) from reporting from other sites that all 3TB WD Reds are SMR when in fact there are two models. I have many WD external drives, and i DON’T WANT any drive with SMR!!! And upon further investigation I found out that these disks are SMR. (EDIT -> COPY or CTRL-C). *update. By opting-in you agree to have us send you our newsletter. Robert Dole, Spend a little bit more money for the 54/5600 – 7200 RPM drives that are CRM. We found SMR can put data at risk 13-16x longer than CMR. About 5 years ago I bought a Seagate 8TB Archive SMR disk for backing up my FreeNAS. Then I found out about this lawsuit. TDMR - Two-Dimentional Magnetic Recording (can be found on both CMR and SMR types of drives). Taking into account that you regularly make backups from the backups. NAS drives are always a gamble, SMR or not, you should always keep away from the cheap HDD drives and that also includes cheap SSD’s if you are trying to have a NAS that have a good performance in a Raid setup. The WD blog says the WD40EFRX is CMR, yet I see no “Plus” written on the drive. Ontop of that, when enquiring WD, they refuse to clarify whether they are PMR or SMR. I truly would like to know in order to make a decision. From the brief I now know the 3TB drives I bought for my Synology are CMR. Period! Whilst the HDD makers have been playing these subamrnining games over the last 2 years, they've failed to notice that first Samsung parked a howitzer across town with the 860 QVos and that now Micron have parked tanks on the HDD makers' lawns with their 5210 ION and 5200 ECO drives- these drives have been around for a while, but Micron took 1/3 off the pricing 6 weeks ago and that brings them well into the "Jumping off" territory for enterprise storage purchasers(*). Edit: Back in stock with local store pickup also. Clearly the problem is with the label on the drive. Just got off the phone with a Seagate rep. And I’m fuming right now. Based on my time with those drives, I was expecting much poorer results. If you use WD Red CMR drives, you had class-leading performance in this test but if you bought a WD Red SMR drive, perhaps not understanding the difference, you would have another 9 days of potentially catastrophic data vulnerability. 3. I had such a great week too. JimDeLaHunt June 1, 2020, 3:46am #10. marcolopes: 60EFAX are SMR! List of WD CMR and SMR hard drives (HDD) Updated table : 23/10/2020 Now … ☎ Buy Western Digital WD Red Plus (CMR) WD40EFRX 4TB 3.5" SATA 6Gb/s 5400rpm at the best price » Same / Next Day Delivery WorldWide -- FREE Business Quotes ☎Call for pricing +44 20 8288 8555 sales@span.com Free Advice Maybe I’m in the minority here. Also, if you trim the entire disk (and maybe wait a little), does it return to initial performance? I will NEVER buy another EXTERNAL WD drive again without the warranty to check the internal drive MODEL first!!!! That level of SMR on a black is just not acceptable. Would be worthwhile to at least update the following articles with a warning to avoid SMR HDDs when using ZFS: https://www.servethehome.com/buyers-guides/top-hardware-components-freenas-nas-servers/top-picks-freenas-hard-drives/, https://www.servethehome.com/hpe-proliant-microserver-gen10-plus-ultimate-customization-guide/2/. Testing the WD Red 4TB SMR WD40EFAX Drive. Given the significant performance and capability differential between the CMR WD Red and the SMR model, they should be different brands or lines rather than just product numbers. EDIT: Just checked, the drives are WD40EFRX. I wonder to what extent can performance be regained with its use. 色と容量で公開しているのは 今現在の生産もしくは今後の予定であって 今現在市場にあるもののことではないんだよ There’s an image on WD Red 4TB page which has “WD40EFRX” but only says WD RED. I do get the unhappyness about not branding correctly but I cannot beleive that the results are this severe for consumer NAS especially ? Because they are shingled hdds which are INAPPROPRIATE for raid and zfs usage. Perhaps that was because we were testing the use of the drive as a replacement rather than building an entire array of SMR drives. Most people do not understand how complex SMR is when data needs to be moved from a bottom shingled track. https://www.cnet.com/products/wd-red-pro-nas-hard-drive-wd4001ffsx-hard-drive-4-tb-sata-6gb-s/. I already changed motherboard once because I thought it was a motherboard issue. https://arstechnica.com/gadgets/2020/05/western-digital-gets-sued-for-sneaking-smr-disks-into-its-nas-channel/, Form to join the class: Good analysis. Guess I should be happy all mine are EFRX as well…, Someone said this is part of a RACE for BIGGER capacities. It takes balls to do it but know I appreciate it. To be crystal clear, I knew what SMR was, and that the drive used it. Because in the case of WD40EFAX, they totally left that out of mention and refused to clarify, which is pretty scummy. We are going to curate a selection of the best posts from STH each week and deliver them directly to you. There are other NAS vendors who are staying silent on this issue, even if they utilize ZFS and these WD Red SMR drives. Is that the next step? I get that it’s not OK to hide what the drive actually uses, but on a Media Server/Backup level ? Given the significant performance and capability differential between the CMR WD Red and the SMR model, they should be different brands or lines rather than just product numbers. I don’t want a mechanical disk that overlaps tracks and has to write adjacent tracks just to write a specific track!!! Checked the invoice and they are marked as WD40EFRX (phew)…. With that said, all of the tested drives were disconnected as soon as their previous benchmarks were complete, and before plugging them back in for use in our test NAS array. I have 4 4tb WD reds in my Qnap tvs-471. While it’s running well enough at the moment, does anyone know if a scrub is likely to cause a problems with SMR drives? Such a shame, I was happy with putting red drives into client Nas now I will be putting ironwolf, what were Western digital thinking? As an individual drive, the WD40EFAX is performing pretty well in these benchmarks. Is this CMR technology or SMR technology? 2~6tb 사이의 제품만 제품군별로 smr과 cmr이 혼용돼 서 사용된 것으로 되어 있습니다. With the the 3.96 and 7.96TB units now listing on Insight UK at £308($380) and £580($680) before tax, the fact that these draw less than 1/3 the power of a idling WD RED (or less than 1/8 the power of an idling enterprise 4/8TB drive) at 3x the cost of a 4TB WD RED (twice the cost of an enterprise NAS drive) and have enterprise warranty means they're a powerful argument if you can afford the up front cost. Ars articles always lack the depth of real reporting, but do provide an entertainment factor and many times the commenters have much more insight (which is what I love finding and reading). In other words, not only do they have rotten performance that can be expected of SMR drives, they'll actively throw themselves under a bus from time to time - and virtually every time when attempting to rebuild a RAID onto one of these drives, no matter what you try to stop them doing it (hint: Whilst you _can_ make them resilver by playing with drive internal settings, you really don't want to force this to happen. How BIG is it? Had no idea this was a thing but glad I googled it now. Thanks to the public outcry, WD is now properly noting the use of SMR technology in the drives on their online store, and Amazon and Newegg have also followed suit. I saw that Ars piece. Robert – I generally look for low-cost CMR drives, and expect that they will fail on me. Shucking external drives (which are often SMR) is mentioned on both pages. The RAIDZ results were so poor that, in my mind, they overshadow the otherwise decent performance of the drive. Someone said this is part of a RACE for BIGGER capacities. Simply saying SMR is not enough without showing the impact. My use case would just be me and my wife, and once the newborn is at age, perhaps him? We say 9 days and we’re understating the problem, which in my mind is the more defensible position. P.S. Either is bad. They are using smaller capacity drives with different NAS systems. 🙂 Great to see some hard facts related to this after reading about it from others. The performance results achieved by the WD Red WD40EFAX surprised me; my only personal experience with SMR drives prior to this point was with Seagate’s Archive line. 作为对比,官方数据显示使用普通cmr的wd40efrx红盘和wd40ejrx紫盘,质量都是680克。 额外一片磁盘和两颗磁头的质量大概在80克左右。 所以推断新版的圆头4TB紫盘应该是内置了两片磁盘,单片容量2T的 … Sometimes they put in blues or whatever because that’s all they can get. https://www.youtube.com/watch?v=sjzoSwR6AYA. Our data shows that the disk drives WD 4TB Red WD40EFRX are NOT based on SMR technology, the disk drives are based on CMR. CDN$141.64. Older WD40EFRX are CMR/PMR, newer WD40EFAX are the SMR drives. They work aggressively in the background to mitigate their own limitations. That’s why STH is a gem. We wanted to present a real-world use case with ZFS so our readers have some sense of the impact. But great test methodology STH. The general population does not follow drive technology closely. Instead, it is a WD Red drive with NAS branding all over it. Dear Western Digital, you thought you could get away with it because a basic benchmark does not show much difference OR you were not even aware of the issue because you did not test them with RAID. But, selling SMR as a NAS drive, AND not clearly labeling it, (like Red Lite), that should be criminal. There was no information on whether the drives are SMR or PMR, and there were NO indication whatsoever that they should not be used in RAID arrays. Luke, We use ZFS heavily and many of our readers do as well. would be interesting to see RAID rebuild time on a more conventional RAID setup. They were apologetic, but then they dropped the bombshell: All Seagate 2.5″ drives are SMR, they no longer make 2.5″ PMR drives. 【hdd】8tbのst8000dm004 レビュー【smrとcmrの違い】 コストパフォーマンスに優れた8TBの3.5インチHDDとして人気となっている、SegateのST8000DM004。 今回の記事ではこの「ST8000DM004」のレビューに加え、記録方式のSMRとCMRの違いを解説します。 And it looks like WD got caught and now have a class-action law suit brewing: In my opinion, the SMR Reds are a case of fraudulent advertising. AFAIK, the SMR Reds support the TRIM command. The drives perform terrible ever since day 1, causing the whole PC to appear unresponsive for minutes the moment 1 file in the Steam library is rewritten for game updates. Does it strongly depend on the Type of RAID and Filesystem ? Write tests tell a mostly similar story. Anyway when purchasing the drives, even if it's not marketed as SMR, i guess we still have to look hard to verify if the hdd is SMR, PMR or CMR. In both cases, the WD Red SMR drives would not work for me personally. Dear Western Digital, I will probably continue to buy WD Red in the future, but I just voted with my $$$ following that story. That said, his personal IT motto has to be "if it's not broke, don't fix it" so sometimes the old ways are best. One could argue that you may not transfer 125GB files every day, but that is less data than the video production folder for this article’s companion video we linked at the start.
