The problem now is that SMR are firmly embedded and they are here to stay. Your video and web are usually much closer to 1 another. Sometimes they put in blues or whatever because that’s all they can get. It's a virtuous circle (and of course experience shows that SSDs last MUCH longer in service than HDDs, which allows us to stretch our very tight budgets that much further...). That 9 day and almost 14-hour rebuild means that using the WD Red 4TB SMR drive inadvertently in an array would lead to your data being vulnerable for around 9 days longer than the WD Red 4TB CMR drive or Seagate IronWolf. From the brief I now know the 3TB drives I bought for my Synology are CMR. Since my source had 4 x 4TB WD Red CMRs, using a single 8TB drive for backups was perfect. 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 … I will NEVER buy another EXTERNAL WD drive again without the warranty to check the internal drive MODEL first!!!! What makes this worse is, there is no mention that these WD RED NAS hdds are SMR in their specification page. So glad I got 12TB Toshibaa N300’s last year that are CMR. AFAIK, the SMR Reds support the TRIM command. Maybe Seagate ironwolves? 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. 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’d like to say thanks to Seagate for keeping CMR IronWolf. Great article, thanks for the info. EDIT: Just checked, the drives are WD40EFRX. Replacing with 1 SMR disk. Reds aren’t cheap either, but they’ve previously been good. If so, this is the best deal for a … Now I know I’ve sold my customers FreeNAS hardware that isn’t good. 2) For backup purposes SMR HDD and QLC SSD is a good choice. Dear Western Digital, I will probably continue to buy WD Red in the future, but I just voted with my $$$ following that story. Not that I would use SMR for NAS. marcolopes. 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. 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. It seems like a marketing TEST!!! As an individual drive, the WD40EFAX is performing pretty well in these benchmarks. (EDIT -> COPY or CTRL-C). +1 on rep for it. Either is bad. Clearly the problem is with the label on the drive.

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. I thought it was good in explanation, but it’s odd. The WD40EFAX turns in performance numbers that are significantly worse than the CMR drives. 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. I already changed motherboard once because I thought it was a motherboard issue. 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. ☎ Buy Western Digital WD Red (SMR) WD40EFAX 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 CMOSTTL this basically shows stay away from SMR even for backup in NASes.

Great piece STH. page https://www.westerndigital.com/products/internal-drives/wd-red-hdd. The RAIDZ results were so poor that, in my mind, they overshadow the otherwise decent performance of the drive. They are also not doing a realistic test since it seems they are not putting a workload on the NAS during rebuilds? Robert – I generally look for low-cost CMR drives, and expect that they will fail on me. I do get the unhappyness about not branding correctly but I cannot beleive that the results are this severe for consumer NAS especially ? The SMR drive has a much larger cache than the CMR version, 256MB vs 64MB, which perhaps helps account for the win here. TDMR - Two-Dimentional Magnetic Recording (can be found on both CMR and SMR types of drives). I wonder to what extent can performance be regained with its use.

Will has worked in both big enterprise and small business IT since 2001. Any chance anyone has a link to that? Would be interesting to test on consumer devices such as Synology or QNAP ?

Why keep SMR and PMR drives with the SAME capacity in the same line and HIDING this info from customers? Plus, I’d like to see some stock hardware RAID devices tested along the same lines.

Is WD USING RAID / more demanding users as “guinea pigs” to test SMR and then move on and use SMR on +14TB drives (that currently use HELIUM inside to bypass the theoretical limitation of 6 platters / 12 heads)??? But the question for me (as somebody who is about to buy a new NAS as a media hub for Videos and Photos) I still have two old st4000dm005 lying around and would use them and upgrade two additional a cheap 8TB (SMR – st8000dm004) or with the whole SMR NAS drive debate, a very expensive CMR Ironwolf or something like that ? So they go way into the weeds of commands (that the average QNAP, Synology, Dobo user has no clue about) then say it’s fine… oh but for ZFS its still sucks. We are going to start with some general benchmarks to try and place the WD Red (WD40EFAX) performance in a larger context. 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. Unfortunately, while the SMR WD Red performed respectably in the previous benchmarks, the RAIDZ resilver test proved to be another matter entirely. In online product catalogs keeping the same branding means that it shows as a “newer model” at many retailers. Just got off the phone with a Seagate rep. And I’m fuming right now.
