現実のSMRの動作なんてどうでも良いらしいよ？ 412 ：Socket774 ：2020/01/23(木) 16:45:25. It seems WD are STILL attempting to minimise the issues and as the call cut off about that point – about 30 minutes in – I’m not really in a mood to play their silly games. I can see their argument now: “But look! Saving $1 per drive adds up when you are selling tens of millions of drives per quarter. The drive manufacturers also know that SMR has a certain stigma to it. You can read the full statement here. All of those companies do, indeed, disclose the use of SMR technology openly for their higher-end customers. Not long ago, 4TB hard rives were hovering around $100, now I see Newegg is selling the WD 4TB drives for $65. As some have commented elsewhere on this article, these low capacity drives aren’t falling in price with the introduction of SMR either.

(One month late because I've been lazy.) Current tests indicate CMR processes - older product reviews give reason to assume that it is SMR. Host-managed SMR is where hosts and software are designed specifically to optimize and send commands for SMR drives. latency read write read write read write read write scrub trim Instead I purchased these 10TB not just 1 but 2 hard drives. This also claims the WD80EFAX are not SMR. If you have any helpful information please feel free to post on the forums. Find answers in product info, Q&As, reviews. I am looking to purchase an external 10TB drive to shuck, but i'm not sure what the differences are between the two are; do you mind filling me in? Sounds to me like the head loses the track and tries to relocate itself. Most of my failed SSDs come from poor firmware that has no updates or vendors that do not make those updates widely known or easily obtained. 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. Hey guys, new to DataHoarder here and i'm having a bit of trouble understanding the difference between the WD100EMAZ and WD100EZAZ. I also applaud that you took a firm principaled and honest stance, deconstructing the WD PR speak. To a drive vendor, if you want CMR, the answer is simple. I’ve spent the best past of the last 12 months chasing ghostly “intermittent network hangs” around the workplace. Recently, when replacing a drive in another device, I stumbled on the information about SMR vs. CMR technology. Let us start with why consumers and small businesses buy hard drives, especially NAS drives. 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. The fact that the market is having to pressure hard drive vendors into disclosing this information means that an educated consumer could not get the technology they want. 16us 0 0 0 0 21.7K 1.68K 106K 399K 574K 0 ————————————————————————————————————————, The interesting thing is that the 1/2/4/8/17s stats are virtually the same across all the CMR and SSD units – pointing to OS/ZFS or other issues – but the SMR drives are in a league of their own, I’m the one who collated most of the information and gave it to Chris. I would seriously consider using more SSDs if they used 3D or TLC at most, improved the storage density per cubic centimeter of space required, added power-fail final write support (almost all consumer SSDs lack this), and published further studies on long-term extended read-write performance. I prefer Toshiba and HGST (WD now unfortunately) over plain WD any day. I’ve actually read that post, but there are others that claim they might be. Low capacity also means a lower dollar per drive metric. If they did “seek the knowledge” they would not have found it. 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. If using a SMR platter means you can create a drive with a lower cost or fewer number of platters, then that yields big savings. We typically buy larger drives. First, the drive manufacturers are using DMSMR which effectively hides the SMR label from host systems and customers. Again, the data storage industry stepped up here. Learn how your comment data is processed. It’s now in the hands of the UK courts. This kind of thing should be the first thing after the HDD designator. Many consumers may be priced out of the market.

Generally, think of this as tens of millions of drives per quarter, but mostly to only a few customers. In many ways, they have if you look at the mobile markets. Western Digital updated its response and included which drive models are SMR. The more I see SSD makers evolve new potentially unstable, unreliable, and/or low-lifetime tech so they can cram more TB into the same 2.5 inch form factor, the more I cringe at the thought of the massive amounts of data loss in a medium once known for high reliability. El problema es que WD pasó de usar tecnologia CMR a SMR en los WD Red sin avisar. Then I would send my bill including for the replacement performant array, to the vendor. WD100EMAZ SMR Check Our data shows that the disk drives WD 10TB WD100EMAZ are NOT based on SMR technology, the disk drives are based on CMR. I think it is possible that the HDD makers will see this debacle as a chance to further segment the marketplace. In the past the 2TB to 6TB market would get drives riding down the cost curve, now that’s no longer possible. @stoatwblr Hat off sir! It sure seems like to me a bad idea that blew up in their faces. The reputational risk of data loss or just fear that you might are greater than the enterprise in most small professional companies, If you haven’t watched the video you can just watch starting here https://youtu.be/gSionmmunMs?t=1328, That’s like how my dad used to tell me my friends and I were being dumb@$$es. For 'Shuckers' this will usually contain a WD100EMAZ-00WJTA0 'White' Drive, with apparently a small chance of being a WD Red drive.

Having a backup of that data is important whether it is in a PC, NAS, or the cloud. It seems like any cost saving is being eaten up by lost selling price. I’ve been reading and hearing about this SMR mess the past few weeks and was wondering if the MFRs would change and begin disclosing to all of their customers, not just disclosing on the more expensive enterprise drives. 1us 0 0 0 0 12 7 99 47 35.0K 0 1 Mil Kapton Tape (Polyimide) - 1/2" X 36 Yds, WD 12TB Elements Desktop Hard Drive, USB 3.0 - WDBWLG0120HBK-NESN, Seagate BarraCuda 8TB Internal Hard Drive HDD – 3.5 Inch Sata 6 Gb/s 5400 RPM 256MB Cache for Computer Desktop PC – Frustration Free Packaging (ST8000DM004). Unless HAMR/MAMR and bit patterned media hit the market in a remarkably short period of time – and remarkably cheaply – I’d say the days of spinning media are very much numbered. Plus even those on the sidelines not current on technology, will hear, Stay away from Western Digital. Effectively, buyers in the 2TB to 6TB market are often ones who do not know about SMR v.

I’m in the UK. As SSDs get closer to hard drives in terms of price per TB (and in some ways performance) selling a hard drive becomes a challenge. That is a similar concept, just at faster transfer rates than in the hard drive world. Over the past few years, the industry has had a mantra of SMR is for large storage systems with sequential I/O.

While the industry recognizes its use as a tool, especially with larger storage pools, they also undertook, as an industry, a campaign to educate the market that SMR was not for most buyers.

Fortunately those drives have been relegated to rarely & barely used “cold storage” RAID systems. 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.
