I think it is possible that the HDD makers will see this debacle as a chance to further segment the marketplace. Within 10 years I don’t see HDs being viable vs SSDs.

Samsing parked a howitzer across town with the 4TB 860QVO and their 16/31TB SM886 drives, Micron have done one better than that: Their Enterprise archival/coldstorage 5210 ION drives – intended to take on 10krpm SMR drives – were recently reduced by about 40% and are now only double the price of spinning Enterprise SMR media, 3.96TB – £308+VAT(380+tax), 7.96TB – £580+VAT($680+tax), This is very much “tanks parked on the hdd factory lawn”, These are only rated at 0.2-0.8DWPD, but as Micron point out, that’s still more rewrites than comparable storage gets – and I’ll point out that this kind of drive at this kind of endurance will match 80-90% of home workloads – which tend to be write once anyway, “the boresights are squarely aimed at SMR drives”. Next, we wanted to talk a bit about the different lenses that both drive manufacturers and consumers are coming from. For 'Shuckers' this will usually contain a WD100EMAZ-00WJTA0 'White' Drive, with apparently a small chance of being a WD Red drive. Those are excerpts from the Toshiba paper they linked and showed in the video. As these firms grow, through absorbing competitors, they can use the best technology and standardize on a fewer number of models, thereby driving up volumes.

LOL memories of 30 years ago. 31ns 0 0 0 0 0 0 0 0 0 0 These are customers who lack other options or purchasing power and the hard drive manufacturers are treating them worse because of it. The reason hard drive manufacturers went through brutal decades of consolidation is that the business is largely dependent on volume manufacturing. 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 2TB to 6TB market is not for buyers like STH, or even me personally. 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.

To get the right price, open the link above, then in the "Frequently bought together" Section at the bottom, deselect the other offerings, then "Add To Cart". It’s telling that the manufacturers don’t utilise SMR in high-capacity 8-16TB drives for the most part, despite SMR’s purpose being to get more density (=higher capacity drives). 7ns 0 0 0 0 0 0 0 0 0 0 127ns 0 0 0 0 0 0 0 0 0 0 Second, the drive manufacturers are not telling the market they are or may be selling DMSMR drives. Albert they already charged the same price as a Cmr drive in the red product line but made the switch to SMR and put the money in the pocket. state: ONLINE There are effectively two types of consumers here. I suspected as much but they are not the only ones. 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.

Tomas H. – If you watch the video, you may notice this was written about a week ago. 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. I’ve had a problem with a 4TB 2.5″ (15mm height) which looks so good on paper but resilvering to it takes inordinate amounts of time.

Likely the use of SMR technology was seen as a benefit to delivering less expensive drives in the market when many users simply would have no idea a switch from CMR to SMR was made. Called tech support, the 1st agent did not know what PMR or SMR are. Please try your search again later.

In many ways, they have if you look at the mobile markets. Even that Toshiba paper mentioned earlier discusses that the technology is for higher-capacity drives, not low-capacity drives such as in the sub 6TB segment. @Patrik: Thank you for this article, the best as i said above IMHO on the topic far and wide.

Saving $0.50 or $1 here in manufacturing costs can make or break a product in the market. It also analyzes reviews to verify trustworthiness. Also, I knew Seagate’s Archive drives were SMR, and I recognise some people would accept that given the price/GB. Over the past few years, the industry has had a mantra of SMR is for large storage systems with sequential I/O. I just want to know why it took you so long to comment on this. We are taking special note of Western Digital here. 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.

Selling an SMR drive in the WD 27 Nov 2019 I have used Ironwolf 8TB and some old 8TB Seagate Archive SMR drives as well. The last major survey of consumer SSD reliability that I read was published by the legacy “Tech Report” web site; the current “Tech Report” web site is sad by comparison. I bought a 6TB Red drive last year and I noticed the performance initially appeared great (the drive’s CMR portion) which then plummeted since. Hope they learn from it. I have checked 75 percent of my WD RED drives so far and they are all CMR drives; their part number does not match what WD says are the WD RED SMR drives. There are a lot of resources out there to explain exactly how this is done. As a result, host-managed SMR are generally used in storage systems from big vendors and hyper-scale customers where this logic can be built into the entire storage paradigm at scale. Initial failure rate was 2% – 2 drives out each pool of 96 failed within the stress period – and were swapped out with the spares I bought at the same time. We attempt to answer the burning question of whether the WD100EMAZ (Easystore white label) is the same as the WD100EFAX (WD Red) 10TB hard drive. 1us 0 0 0 0 12 7 99 47 35.0K 0 The traditional “jumping off point” for switching from rotating to solidstate media is 4-5 times the price. What is interesting, is that all of the manufacturers seem to have moved to DMSMR at around the same time, to price drives about the same. As for SSDs and QLC tech, no thanks, not even for my “cold storage” systems; QLC or QVO tech still seems terribly unproven to me and mostly unexplored by tech web sites. 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.

We typically buy larger drives. Our publishing chain is a lot longer these days, and the pipeline is full until June 2020 already. Effectively write patterns are changed which allows denser data recording. All of those companies do, indeed, disclose the use of SMR technology openly for their higher-end customers. Shuck it and start using it, I noticed that there's random noise from the drive when reading / writing. Effectively where we are is that the oligopoly of hard drive manufacturers is using inferior technology, without disclosing it, on classes of customers who have no realistic alternatives to protect their vital assets and livelihoods.

Changing a previously working device’s internals for something that works “similarly for a few seconds”, then suffers severe degradation – 90-98% on raid rebuilds and 40-60% when treated just right, whilst keeping packaging and marketing identical, is the kind of thing that brings authorities down on a company like a ton of bricks. @Nikolay: It’s a virtual certainty anything larger than 2TB in 2.5″ is SMR.

First, we wanted to discuss the perspective of why a hard drive manufacturer would put a DMSMR drive into a consumer platform. Soon, virtually all primary OS and application disks will transition to SSDs. I prefer Toshiba and HGST (WD now unfortunately) over plain WD any day. The company simply stated, “We will update our marketing materials, as well as provide more information about SMR technology, including benchmarks and ideal use cases.” (Source: WD) That is not a pledge to clearly and accurately disclose recording technology on all drives going forward.
