I do get the unhappyness about not branding correctly but I cannot beleive that the results are this severe for consumer NAS especially ? Instead, individually the WD Red SMR drives Are essentially functional. The potential for confusion is still high though. This whole thing really does look like cartel behaviour to me - something the Chinese market regulator was explicitly worried about with the mergers going on the late 00s/early 10s' and why it forced HGST/WD to run as separate entities for more than a decade after acquisition. For my use, (it was the only 8TB drive on the market for a reasonable price at that time), it works well. ServeTheHome ran a full suite of benchmarks on the 4TB WD Red NAS WD40EFAX (SMR) versus the 4TB WD Red NAS WD40EFRX (CMR). It seems like a marketing TEST!!! A great example is http://blog.robiii.nl/2020/04/wd-red-nas-drives-use-smr-and-im-not.html. I want to point out that you’re wrong about one thing. Is that the next step? I learned this lesson a few years ago with Seagate SMR drives and a 3ware 9650se. It takes balls to do it but know I appreciate it. Having rolled out DM-SMR at 98% of the the price of CMR, WD/SG/Tosh are not going to wave a magic wand and say "oops sorry, we furfued this, here's your CMR drives back at the same price". This is the revision of firmware that came on both of our drives. If you watch the video, it’s funny. It is strange not to at least generate some workload during a rebuild. P.S. By opting-in you agree to have us send you our newsletter. I am looking to create a Plex Media Server for music, videos, tv shows, photos, etc. At the start you’d think he’s anti-WD but by the end you realize he’s actually anti-Red SMR. +1 on rep for it. ☎ 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 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’m thinking YES!! Something we noticed is that the test that immediately followed the file copy test was a sequential CrystalDiskMark workload: As you can see, with a heavy write workload immediately preceding the CDM test, the SMR drive was notably slower. 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. In the file copy test, the effects of the slower SMR technology starts to show itself a bit. Thank you for your time Ektich we load test every drive before we replace them in customer systems to ensure we aren’t using a faulty drive. Was there nobody on the team who realised the consequences? You can still buy the WD40EFRX currently. I will also say that a likely part of the problem here is that these are DM-SMR drives that hide the fact they are SMR from the host. I think you should explain how SMR works with a bunch of images or an animation. In these kinds of shorter burst activity workloads, one can see how SMR may be used as a substitute. 3. The WD40EFAX turns in performance numbers that are significantly worse than the CMR drives. My backup window is not time constrained, I simply let it run until it’s done. And this is VERY BAD NEWS. My use case would just be me and my wife, and once the newborn is at age, perhaps him? Why is that? New comments cannot be posted and votes cannot be cast. 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. 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. WD Red = CMR, WD Pink = SMR. Shipping only, not available in most stores. It can be… BUT, before that happens, WD is probably using the most demanding customers / environments to TEST SMR tech so they can DEPLOY them in the bigger capacity DRIVES: 8, 10, 12, 14TB and beyond (do not currently exist). and what replacement hdds do you get if replaced under warranty (especially since HGST got bought by WD)? The drive does say WD40EFRX, but says “WD RED” rather than “WD RED PLUS” as advertised. They were apologetic, but then they dropped the bombshell: All Seagate 2.5″ drives are SMR, they no longer make 2.5″ PMR drives. 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. 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. 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 … Either is bad.
