NAS Compares. 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. Testing commenced immediately after the drive prep was completed. But, selling SMR as a NAS drive, AND not clearly labeling it, (like Red Lite), that should be criminal. I’d really like to go through all my drives and explicitly verify which ones are SMR vs CMR. But great test methodology STH. That’s terrible practice. Just read this bollocks: https://arstechnica.com/gadgets/2020/06/western-digitals-smr-disks-arent-great-but-theyre-not-garbage/2/. WD Red HDDs are ideal for home and small businesses using NAS systems. Does it strongly depend on the Type of RAID and Filesystem ? Just got off the phone with a Seagate rep. And I’m fuming right now. Le WD Red a été spécialement développé pour les systèmes NAS qui ont une à huit baies de lecteur de 3,5 pouces et 2,5 pouces. 4. More trolls on STH when you get to these mass audience articles. First, a simple 125GB file copy to test sequential write speeds outside of the context of a benchmark utility. I do get the unhappyness about not branding correctly but I cannot beleive that the results are this severe for consumer NAS especially ? And it looks like WD got caught and now have a class-action law suit brewing: Surtout, vous pouvez compter sur SMR si vous voulez des disques durs volumineux avec des coûts de matériel inférieurs et une consommation d’énergie électrique généralement inférieure, qui servent de purs périphériques de stockage de données. Built and tested for personal and home NAS systems with up to 8-bays, these drives pack all the punch you need in one powerhouse unit for storing, archiving, and sharing. I’m also happy to see you tried on a second drive. I just want a clear demarcation. It’s about time a large highly regarded site stepped in by doing more than just covering what Chris did. A great example is http://blog.robiii.nl/2020/04/wd-red-nas-drives-use-smr-and-im-not.html. But it is not recommended to use SMR drives for applications with significant load (for example in NAS boxes or for 24x7 use). Also, NAS units and RAID arrays are designed to continue serving applications and users when in degraded states. If people can sue Apple for advertising a phone has 16GB of storage when some of that is taken up by the operating system, those two missing words may make a huge different in the legal circus. SMR drive support is getting better when hosts know they are using SMR drives. If you round to nearest day it’s 10 days not 9. Disciple. Sometimes they put in blues or whatever because that’s all they can get. WD Red SMR vs CMR Tested Avoid Red SMR | Page 2 of 2 | ServeTheHome. (BTW, if you ask WD how to know the DRIVE MODEL inside an external WD enclosure, they will tell you it’s impossible!!! Even with a cache flush they’re hitting steady state because of the rebuild. They are also not doing a realistic test since it seems they are not putting a workload on the NAS during rebuilds? WD technicians don’t have a way to query the drive and ask for the model number?? Après l’enregistrement, les données sont transférées du contrôleur vers la zone SMR dès que possible. For the test configuration, we wanted a configuration that de-emphasized CPU performance. 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)???
