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. But now it appears that the WD Red 2TB, 4TB and 6TB Standard class NAS 3.5″ Hard Drives do indeed feature this method of platter utilization inside and it’s upset a few people indeed, but the details are not as black and white as some might think. Hard drive discs made using SMR technology are less expensive to make than those that use CMR, states the complaint, further noting that Western Digital began using CMR to manufacture hard drive discs and sell them to Canadians in 2012. 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. But it is not recommended to use SMR drives for applications with significant load (for example in NAS boxes or for 24x7 use). 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. iXsystems and Western Digital have been working to identify and resolve the ZFS compatibility issue with the WD Red DM-SMR drives.

NAS drives are expected to perform well in RAID and other multiple disk arrays, whether ZFS pools or consumer devices like Synology or Netgear NAS appliances. WD Red capacities 2TB-6TB currently employ device-managed shingled magnetic recording (DMSMR) to maximize areal density and capacity. 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. It is often desirable to choose a CMR drive instead. Having built this reputation, we understand that, at times, our drives may be used in system workloads far exceeding their intended uses.

We will not share your email with any third party companies. 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. It isn’t clear whether Western Digital will update its marketing materials to show that its 2 TB – 6 TB Red NAS are SMR drives. 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. In a traditional RAID1/5 rebuilt the drive is sequentially rebuilt from start to end. The 8TB and larger drives with the “EFAX” code use CMR technology. The results demonstrate that although Western Digital's new 4TB Red "NAS" disk performed adequately as a desktop drive, it was unfit for purpose in a ZFS storage array (zpool). “The past week has been eventful, to say the least.

The new disclosure comes on the heels of WD's blog post yesterday that outlined its stance on using SMR drives. We can hypothesize that there is a negative impact, but it is better to show it. SMR technology is implemented in different ways – drive-managed SMR (DMSMR), on the device itself, as in the case of our lower capacity (2TB – 6TB) WD Red HDDs, and host-managed SMR, which is used in high-capacity data center applications. 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. We are continuously innovating to advance it. Help Others! 15TB HDD – Taking Big Data Capacity to the Next Level.

Need Advice on Data Storage from an Expert? As such, host-managed SMR allows for a smooth, staged transition to Host-aware SMR in a future timeframe. WD Red 8-14TB drives use conventional magnetic recording (CMR). 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. 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). ... saying that it responds to “product replacement requests” on a “case-by-case basis”. Western Digital late last week issued a statement in response to the revelation of the company’s undocumented use of SMR (Shingled Magnetic Media recording) in 2TB and 6TB WD Red NAS drives. You must login or create an account to comment.

This post has been updated accordingly with these new details. Your story on WD using SMR in some drives without mentioning it on the spec sheets was eye opening. Realizing this is a little difficult to track, Western Digital has provided a chart to identify all of their drives with DM-SMR. We’ve rigorously tested this type of use and have been validated by the major NAS providers. 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. WD Red drives are designed and tested for an annualized workload rate up to 180TB. The issue isn’t that we don’t understand SMR or DMSMR. Let’s take a look at the news.
