Toshiba’s “voluntary” disclosure to Chris Mellor misses out the status of their NAS, Survellance, Videostreaming and enterprise storage ranges. This is tech journalism at its best. The best solution would be for drive manufacturers to provide a way for the host to know it’s dealing with a DM-SMR drive, and for OS and NAS providers to write code that takes it into account. Selling a customer/family/smb, an advertised Safe/reliable House that blows away at the first sign of a heavy wind does NO ONE ( customer, sales rep, company and it’s customer “TRUST”) any favors.

I’m in the UK. This is the official company position, however, no executive seemed to want to take ownership of it which seemed a bit strange. They are using SMR in their “premium” WD Red NAS drives. I think SMR vs CMR should be required on the spec sheet just like how cameras basically need to list sensor size. As Patrick has pointed out, some customers pay much higher prices compared to similar goods in other countries, so expect that consumer segment to get stuck between the proverbial rock & hard place. I am interested in higher capacity and higher density SSDs because the alternative is not having enough SATA connectors to hook it all up in a reasonable consumer-sized case. 511ns 0 0 0 0 0 0 0 0 0 0 65us 8.69M 6 9.76M 8 4.65K 83 29.0K 75.0K 87.9K 2 Considering they market SMR and non-SMR drives similarly without clarifying that certain products within the same product lines use completely different technologies, I’m sure lawsuits will find this misleading advertising.

While many of our readers in the US may think of these segments as very small or struggling businesses or consumers without exorbitant means, that is a very narrow view of the world. This data comes from user reports. Do they have TRIM support? In the meantime, it came out that it was not just Western Digital using SMR surreptitiously in drives, but Seagate and Toshiba as well. It sounds like I have described a consumer-grade SSD (lower TBW) based on Enterprise tech; so be it.

Second, the drive manufacturers are not telling the market they are or may be selling DMSMR drives. In the SSD world, this is very similar to how modern QLC SSDs often buffer writes in SLC then transition to slower or higher density storage later. I suspected as much but they are not the only ones. My best performing SSDs use MLC; the next level down are the 3D and TLC models. First, the drive manufacturers are using DMSMR which effectively hides the SMR label from host systems and customers. As far as I’m concerned, SMR driver are glorified tape drives. ————————————————————————————————————————, # zpool iostat -Td -w scsi-SATA_ST4000VN008-2DR1_ZGY6SM46 Not only is WD using SMR in their consumer drives where buyers may have no reasonable alternatives, but they are also going a step further. Think about the worst possible case scenario for SMR drives – lots of concurrrent reads and writes – and now think about how most filesystems work – can anyone say “access time metadata updates” ?

SATDREAM.TECH : informations et aide au choix de disques durs dans le cadre d'une utilisation personnelle. Something drive manufacturers use to mitigate this is to have a cache of sorts with a more conventional recording area that can ingest writes for later migration to the slower SMR section during otherwise idle periods. 68s 0 0 0 0 0 0 0 0 0 0 Thank you for doing this on behalf of everyone that values their data.

I am not perfect in my editing, but I am hoping that at STH we are doing a better job and continue to do so. When we look beyond the US, smaller customers have to face distribution challenges, currency, and local market gaps, and well as tariffs that can make 2TB to 6TB drives relatively very expensive. Filled out an online email form and received no answer. Sounds to me like the head loses the track and tries to relocate itself. (Seagate, Tosh and WD drives, depending on whatever HP was putting in their £1300 Eltedesk800s that day), The problem is far from over: On the WD blog page, there’s a link to support with a specific number to call for WD REDs – which from the UK was answered by someone speaking spanish, who then knew nothing about WD RED issues, but pulled up a canned statement that “we have been informed there is a minor problem in 3rd party NAS system where they may not perform properly in some RAID configurations which we do not recommend”.

Effectively, buyers in the 2TB to 6TB market are often ones who do not know about SMR v. CMR or have no other choice. For those who think it is OK to obfuscate vital product information to a lower-cost segment of customers, I offer this: just because someone or some business does not have the opportunity or means to purchase a higher-end drive, does not mean we should deprive them of an opportunity to make informed purchasing decisions to protect their livelihoods and memories. The reason that people consider SMR to be a concern is that the different recording leads to very different write characteristics, especially on random writes. And the PR from them only is making it worse.

This article has fewer amazing high-end hardware photos than our normal review content. We typically buy larger drives. Still feeling annoyed that it wasn’t what i thought i was buying, and might affect ability to add drives and use RAID. That’s the point. In my April 16 post, I reported what WD support told me, and I said, “I don’t entirely believe it”. The main benefit of SMR, and why the technology is used, is because these large customers demand higher data densities and lower cost per PB numbers, even if individual drive performance is not great. For example, at STH it has been almost three years since we have purchased under 10TB hard drives, simply to reap the benefits of higher storage density. A big reason the storage market is littered with failed startups is just how long it takes to garner that trust because data is important, and it is vital. The 2TB to 6TB market is not for buyers like STH, or even me personally. Oh, I agree. Please try again. This site uses Akismet to reduce spam. Not ideal, but it is where we are. I think it’s in WD’s interest to label SMR vs CMR also because it gives people an incentive to buy higher-capacity CMR drives. The big question is whether the large hard drive manufacturers are able to take this as a learning opportunity and be honest and open about their specs. The first are ones who do not know, nor will they ever know what a SMR drive is, and why one does not want it. Seagate are – of course – Seagate… So far we know that the Barracuda, Barracuda compute (sold to us as “perfomance storage”) and storage drives are SMR but they’re staying quiet and are likely to do so until forced to open up. In the US (N.Y.), I would report this to the NYS Atty. Having looked at what drives use SMR, I suspect WD/Seagate/Toshiba will take advantage of this situation to justify stopping manufacturing of lower-capacity drives because SSDs are gradually taking over those segments and the low-capacity drives can’t compete on price much because there’s a base cost for components like a 3.5″ shell, the controller, the head and motor. This kind of thing should be the first thing after the HDD designator. Indeed, when the first reports were coming out, we had just finished buying Western Digital drives for, and starting a series comparing clustered versus traditional RAID storage for higher-end home and SMB setups. Seagate, for its part, is still using CMR in IronWolf alternatives. In fact, if you look at the ATA specs written several years ago to accommodate SMR, it was designed to deliberately hide the fact that a drive is DM-SMR from the host. 4ms 193K 450K 230K 550K 62 0 3.06K 200K 51.0K 23 If the drive companies provide CMR drives in this storage range, it will cost more. In the past the 2TB to 6TB market would get drives riding down the cost curve, now that’s no longer possible. Current tests indicate CMR processes - older product reviews give reason to assume that it is SMR. 127ns 0 0 0 0 0 0 0 0 0 0 latency read write read write read write read write scrub trim In other words, where HDD makers are now finding themselves.
