Hey Boss, WD is being sued over this. At the time of writing, this drive can be bought for £292 in the UK and $324 in the US if sourced from Amazon. The WD Red Family It works great, but I'm a little bit uncertain whether the write/read are slower than they should be. I think it’s very unfortunate and quite disappointing that WD has no idea what kind of drives they’re selling, and worse still, SMR drives have a lot of problems that WD is not standing behind. It said something like “using WD’s PMR technology…” (in other words, the original way used since at least the 80’s). I have two drives I have many WD external drives, and i DON’T WANT any drive with SMR!!! WesternDigital continues to “hide” what technology is used in your hard disk. In other words, a radio transmitting at 1,5 W or even at 3 W will not get any more PMR radio range. Unhelpful (2) They are conventional PMR drives with NAS firmware. DM-SMR - Device Managed Shingled Magnetic Recording. All were PMR. Just got my black friday WD Easystore opened. And this is VERY BAD NEWS. Called tech support, the 1st agent did not know what PMR or SMR are. The UltraStar, Enterprise, Gold, and Purple series aren’t disclosed either. I say this because, WD has the same “infected SMR drives” using the well known PMR tech! Period! The WD101EFAX also seems to be the replacement for it but both can still be purchased off Amazon with the WD101EFAX being about $10 more. I removed WD from our preferred suppliers list unless it’s used material - which then goes into something else - suited for refurb material. Gladly, i checked my WD ELEMENTS drives, a NONE of the internal drives is PLAGUED by SMR! Oh, also, it … How about that? This is why the drive continues to work long after a large write operation …it’s flushing the PMR space to SMR area. ... At least its not SMR. The PMR space is like temp work space that is written to at normal drive speed and slowly written to the SMR areas after. STUPID of me!!! JoeySmyth.

How BIG is it? FYI, the 10TB uses a similar WD100EMAZ helium drive. Shingled Magnetic Recording (SMR) suffers from reduced write speed, sometimes a lot. Using SMR technology instead of conventional magnetic recording allows HDD manufacturers to put out denser drives at cheaper prices. We found SMR can put data at risk 13-16x longer than CMR, Someone said this is part of a RACE for BIGGER capacities. This interest led Western Digital to create the WD Red NAS-optimised family of hard disk drives. PMR - Perpendicular Magnetic Recording (both CMR and SMR type drives use it). It seems SMR is used to push capacity sooner than PMR is ready for, but they eventually seem to make some (bought a WD gold 7200 RPM drive that’s PMR).

Easystore WD 10… Can’t even answer a simple question on the fundamental technology in the product. No response on that. And after some coaxing, said that they are both PMR, but that doesn’t make sense because of the weight of the drives and their buffer sizes. But fine for archival and backup disks. Shuck it and start using it, I noticed that there's random noise from the drive when reading / writing. HM-SMR - Host Managed Shingled Magnetic Recording. Minimum disk is 12tb large for helium disks now as far as these shuckable externals are concerned.

So… Talk about incompetence and a lethargic response - like they didn’t even give a ■■■■. The second “technician” said SMR stands for Standard Metabolic Rate! Flipping the enclosure over we see how everything is laid out inside the kit. 1 WD-WX21D689KFDL And need to know if these are PMR or SMR. minden (2-4 TB-osokat is) 2,5"-os belső és külső HDD-t érint és a 3,5"-osok egy részét is. No more ADVANCED FORMAT ■■■■ nor SMR. WD - easystore 8TB External USB 3.0 Hard Drive - Black. The popularity of Network-Attached Storage (NAS) systems has fuelled a surge in demand for large capacity hard disk drives. Why is that? I’m thinking YES!! And thus likely resulted in a ton of RMA’s (bit’em in the ass a little). There is no clear marking of which technology is being used. Why keep SMR and PMR drives with the SAME capacity in the same line and HIDING this info from customers? I will choose CAREFULLY from now on, buy INTERNAL drives, and use my own ENCLOSURES! 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).

It’s the principle behind it all. There’s a leading edge WD Red™ drive for every compatible NAS system to store your precious data. The difference in write tech is just the density. People are reporting firmware corruption, file system corruption (happened to me before it died) and slow speeds after the 30-40 GB temporary space (PMR) on the edges of the platters is filled, leaving you with ~20 MB/s SMR write speeds. It seems like a marketing TEST!!! I don’t need more info on PMR. More power than that in the radio brings no benefit, except if the radio is used in DMO. Called tech support, the 1st agent did not know what PMR or SMR are. Dont quote me on this, But a reliabe source told me that those would be SMR, And unlike prev posts that said its only the 2b-6tb, I can confirm my 10tb shuck from BestBuy is a white label SMR as well…Running the 10tb and 4tb non smr together in JBOD the non smr drive runs about 10c cooler than the other, Dunno just an observation, Probably not related at all, Watching atop from cmdline during big dumps 4tb or more, the 10tb goes red and stays red…. In fact they use the technology on mainstream devices like boot drives. WD100EMAZ - the AZ suffix and 256MB cache strongly indicates SMR. Western Digital provides data storage solutions, including systems, HDD, Flash SSD, memory and personal data solutions to help customers capture and preserve their most valued data. Is WD USING RAID / more demanding users as “guinea pigs” to test SMR and then move on and use SMR on +14TB drives??? This because certain drives earmarked for use in NAS were not really living up to the performance expected. This is the optimal output power and it guarantees maximum coverage or maximum PMR range. They are conventional PMR drives with NAS firmware. Tried it with dd and got about ~550MB/s on my Z2 Array. The 8TB EasyStore contains a WD80EMAZ helium drive (up until late 2017 the NAS Red drives WD80EFX).
