Resources: SMR: What we learned in our first year One Year Later…Dropbox Continues to Innovate with Western Digital. Western Digital is now sampling the 20TB Ultrastar DC HC650 SMR HDD and the 18TB Ultrastar DC HC550 CMR HDD, with qualification and volume shipments expected in the first half of 2020. However, the background ‘housekeeping’ tasks that the drive must perform result in highly unpredictable performance, unfit for enterprise workloads. Having built this reputation, we understand that, at times, our drives may be used in system workloads far exceeding their intended uses. The WD Red Pro line remains unchanged with CMR drives. The 9 days vs 16 hours comes from ZFS which when it resilvers does so on a block by block basis completely non-sequentially. The 8TB and larger drives with the “EFAX” code use CMR technology. The WD representative’s wording about the suitability of SMR for archival purposes brings up the question of the WD “White” drives that are included in external USB storage offerings. WD Red 8TB-14TB drives are CMR-based. Should users’ use cases exceed intended workloads, we recommend WD Red Pro or Ultrastar data center drives. In device-managed SMR HDDs, the drive does its internal data management during idle times. Enter your email address to subscribe to this blog and receive notifications of new posts by email.

The Original NASCompares News-Post on these WD Red Drives: Over the last few days, a story has been circulating that revolves around WD Red NAS Hard Drives and their potential use of shingled magnetic recording (SMR) and a statement has been shared by the brand highlighting that this is indeed the case, namely, drive managed shingled magnetic recording (DM-SMR). Need Advice on Data Storage from an Expert? Where possible (and where appropriate) please provide as much information about your requirements, as then we can arrange the best answer and solution to your needs. Ad Choices, with 92 posters participating, including story author, Western Digital adds “Red Plus” branding for non-SMR hard drives, Lawsuit vs. Western Digital wants to end any use of SMR in NAS drives, We put Western Digital’s dreaded SMR Red drive to the test, Western Digital gets sued for sneaking SMR disks into its NAS channel, Seagate says Network Attached Storage and SMR don’t mix. An elaborate investigation and discussion in a Smartmontools thread reveals that both Western Digital and Seagate appear to be shipping HDDs with "DM-SMR" (drive-managed SMR), a feature where the HDD's controller internally performs SMR to increase data density when the physical media is running out of space under CMR (conventional magnetic recording, with conventionally spaced tracks). A firmware upgrade is not possible, as this is a physical build matter and likewise, simply swapping all the drives over is not an option (if indeed necessary) as these drives are likely being used in RAID groups that require gradual and time occupying individual drive replacement and rebuilding/resilvering. Western Digital allegedly failed to disclose the usage of SMR technology in its hard drives. Western Digital has been receiving a storm of bad press—and even lawsuits—concerning their attempt to sneak SMR disk technology into their “Red” line of NAS disks. Realizing this is a little difficult to track, Western Digital has provided a chart to identify all of their drives with DM-SMR. As Synology explains, “rather than writing each magnetic track without overlapping, SMR overlaps each new track with part of the previously written track, much like shingles on a roof.” The result is slower performance and, as evidenced by recurring complaints on r/DataHoarders, problems with RAID arrays. There are three types of SMR: - Drive Managed, DM-SMR, which is opaque to the OS. "We do not have any SMR drives in our Ironwolf and Ironwolf Pro drives, which are NAS solutions [...] we don't recommend SMR for NAS.". If you ever questioned whether your hard drive uses SMR, then this guide would help you. Jim Salter WD has started listing its existing hard drives with SMR technology in marketing materials, and … In collaboration with major NAS providers, we work to ensure WD Red HDDs (and SSDs) at all capacities are compatible with a broad set of host systems. Thank you for letting us know how we can do better. We will have options for you. All our WD Red drives are designed to meet or exceed the performance requirements and specifications for common and intended small business/home NAS workloads. ... We put Western Digital’s dreaded SMR Red drive to the test. Host-managed SMR requires host-software modification so that the host system has knowledge of the underlying media and can micro-control all elements by employing a new set of commands. Additionally, some of you have recently shared that in certain, more data intensive, continuous read/write use cases, the WD Red HDD-powered NAS systems are not performing as you would expect.”. Western Digital, however, was found using the slower tech in its Red NAS drives (2TB-6TB) and soon issued a response on its official blog, an excerpt of … Western Digital begins mending fences in WD Red NAS drive SMR spat – Blocks... Western Digital has heralded a positive shift in its approach to users of shingled WD Red NAS drives, via a short statement on the company blog. This means ZFS cannot "target" writes, and … You are correct that we do not specify recording technology in our WD Red HDD documentation. If you can endure the terrible green screen use and my UTTER inability to pronounce the H correctly, it may well serve as an early window into how this kind of tech was being distinguished even 5 years ago. WD Statement: On the surface, this may seem like the best of both worlds. © 2021 Condé Nast. This site is largely a one man operation and any and all questions and contributions are appreciated. WD Red drives are designed and tested for an annualized workload rate up to 180TB. "Seagate only produces NAS drives that are CMR," Belloni says. It’s that we DO understand it, and that WD has added it to drive models that didn’t have it before, in lines where it is COMPLETELY inappropriate. DMSMR should not be confused with host-managed SMR (HMSMR), which is designed for data center applications having respective workload requirements and host integration. Simply enter the following command: hdparm -I / dev / sda | grep TRIM. SMR drives only need to re-write on altered blocks.

Hattis Law has initiated a class action lawsuit against Western Digital, accordingly. In our testing of WD Red drives, we have not found RAID rebuild issues due to DMSMR technology. But it is not recommended to use SMR drives for applications with significant load (for example in NAS boxes or for 24x7 use). First NAS as a Video Professional: for Back-up and File Sharing? CNMN Collection No one has so far demonstrated 9 days vs 16 hours on a traditional RAID1/5 rebuild. WD Red capacities 2TB-6TB currently employ device-managed shingled magnetic recording (DMSMR) to maximize areal density and capacity. The data intensity of typical small business/home NAS workloads is intermittent, leaving sufficient idle time for DMSMR drives to perform background data management tasks as needed and continue an optimal performance experience for users. Although all three major manufacturers quietly added SMR disks to their desktop hard drive line-up, Western Digital is the only one so far to slip them into its NAS (Network Attached Storage) stack. See Below for SKUs to our client internal HDDs using SMR technology. alltechienewstoday June 6, 2020 5 min read.

Shingled Magnetic Recording (SMR) technology helps hard drive manufacturers to produce HDDs with larger capacity. All other HDDs in these series use different recording technology called CMR or conventional magnetic recording. Depending on the system architecture, implementing these modifications may seem like an onerous task, yet once developers gain SMR familiarity and optimize their applications for sequential writing, they can take advantage of unsurpassed levels of reliability and quality. NEWS Western Digital’s Unacceptable Silence Western Digital has stayed silent on this issue for months, now. Currently, Western Digital’s WD Red 2TB-6TB drives are device-managed SMR (DMSMR). You must login or create an account to comment. With all the recent controversy regarding WD, Toshiba, and Seagate slipping SMR drives into retail channels and failing to disclose the use of their slower technology, we thought it would be interesting to dive into the actual impact of using a SMR drive. If you have purchased a drive, please call our customer care if you are experiencing performance or any other technical issues. With a supported workload rate of up to 180 TB/yr1 and support for up to 64 cameras, WD Purple drives are optimized for surveillance systems. In our testing of WD Red drives, we have not found RAID rebuild issues due to SMR technology. With the ability to deliver predictable, consistent performance comparable to what users expect from traditional PMR drives, host-managed SMR is emerging as the preferred option for implementing shingled magnetic recording. Let’s take a look at the news. However, if predictability and reliability are what you are after, you cannot take any shortcuts in modifying your stack as you would for host-managed SMR. Join the Ars Orbital Transmission mailing list to get weekly updates delivered to your inbox.

Enlarge / Although Western Digital's 4TB SMR disk performed adequately in Servethehome's light duty tests, it performed miserably when they used it to replace a disk in a degraded four-disk RAIDz1 vdev. The two companies most flagged and castigated by technology watchers, pundits and commentators, Western Digital and Seagate, have begun to respond and clarify which models use SMR, and which (in our opinion) should, therefore, be avoided unless price-per-gigabyte is more of a factor in a purchasing decision than read and write speeds. Unless you are using your NAS Drive is an enterprise or heavy-duty capacity, this is not something that is mission-critical in the short term and as long as you have a multi-tiered backup and run checked periodically internally on your RAID array and using the NAS storage tools provided – though you should consider the importance of this in conjunction with the importance of your data! Western Digital works extensively with customers and the NAS vendor and partner communities to continually optimize our technology and products for common uses cases. In a typical small business/home NAS environment, workloads tend to be bursty in nature, leaving sufficient idle time for garbage collection and other maintenance operations. “The past week has been eventful, to say the least. IMPORTANT – This Article has been updated on 23/04/2020 with Information Provided by an official statement and hardware breakdown from Western Digital, from their official blog. WD Red HDDs have for many years reliably powered home and small business NAS systems around the world and have been consistently validated by major NAS manufacturers. Jim Salter. However, typically SMR drives are not intended for random write IO use cases because the write performance is much slower than with a non SMR drive. Host-aware SMR is like a superset of the aforementioned options. Built for 24/7, always-on, high-definition security systems. But Western Digital has been the most brazen of the three, and it's been singled out for a class action lawsuit in response. Recently, on a Synology device, to extend SHR storage i bought 2 x WD WD60EFAX. Drive-managed SMR, where the drive manages all write commands from the host, allows a plug-and-play implementation, compatible with any hardware and software. This post has been updated accordingly with these new details. Help Others! Looking for a Deal on a NAS Drive? One of those innovations is Shingled Magnetic Recording (SMR) technology.

Enlarge / Western Digital's EFAX Red—an SMR disk—squares off against a Seagate Ironwolf in today's testing.Jim Salter Western Digital has been receiving a storm. Toshiba and Seagate confirmed to Blocks & Files that there is undocumented use of SMR technology in some of their drives. Alternatively, why not try asking NAS Community or join forces yourself. ServeTheHome. This means more data can be stored on a shingled disk than an ordinary drive. We reached out to WD and we were furnished with the following reply by Yemi Elegunde, Enterprise & Channel Sales Manager Western Digital UK: Shingled magnetic recording (SMR) is a hard drive technology that efficiently increases areal density and capacity for users managing increasing amounts of data, thus lowering users’ TCO. Where sda is where you … The new disclosure comes on the heels of WD's blog post yesterday that outlined its stance on using SMR drives. DMSMR is designed to manage intelligent data placement within the drive, rather than relying on the host, thus enabling a seamless integration for end users. Our customers’ experience is important to us. We work closely with major NAS providers to ensure WD Red HDDs (and SSDs) at all capacities have broad compatibility with host systems. QLC) and not disclosing it. This is getting absurd. The issue isn’t that we don’t understand SMR or DMSMR. It is often desirable to choose a CMR drive instead.

Back in 2016 we performed speed test on Seagate SMR Archive drives and found them to be good as a standalone drive, but unsurprisingly lacked the robust group utility of RAID use overall: Additionally, Right the way back in 2015 (almost right at the start of the SPANtv YouTube Channel history in fact) we discussed the difference between the larger HDDs that were coming to market that used either SMR or Helium Based storage capacity. (adsbygoogle = window.adsbygoogle || []).push({}); Shop year end deals! Read our affiliate link policy. WD Red 8-14TB drives use conventional magnetic recording (CMR). The fact that WD is stating that these capacities of WD Red (2,4,6TB) use Drive Managed SMR is better than we first thought, it is still off that it is not a factor presented in their datasheets and technical literature. This thread attempts to pull together known SMR drives, and the sources for that information. SMR - Western Digital Corporate Blog ... Five Hard Drive Technologies Making Big Data Possible. As mentioned, Shingled media recording (SMR) HDDs take advantage of disk write tracks being wider than read tracks to partially overlapping write tracks and so enable more tracks to be written to a disk platter. As such, host-managed SMR allows for a smooth, staged transition to Host-aware SMR in a future timeframe. Western Digital reserves the right to change or discontinue this offer at any time without notice. We can hypothesize that there is a negative impact, but it is better to show it. We strive to make the experience for our NAS customers seamless, and recording technology typically does not impact small business/home NAS-based use cases. In contrast to drive-managed SMR, host-managed SMR is an implementation where the host is responsible for everything ranging from managing data streams, to read/write operations and zone management. As a team, it was important that we listened carefully and understood your feedback about our WD Red NAS drives, specifically how we communicated which recording technologies are used. WD Red HDDs are ideal for home and small businesses using NAS systems. Therefore they are not recommended for NAS use cases in most industries, as they feature significant random write workloads. All three of the surviving conventional hard drive vendors—Toshiba, Western Digital, and Seagate—have gotten caught sneaking disks featuring Shingled Magnetic Recording technology into unexpected places recently.
