It trades performance for quiet operation which yields relatively poor performance for its specifications, but it is still useful for NAS.

Original story am ET Last night, a Western Digital executive reached out to Ars to let us know of a blog post concerning their controversial Red drives. This report is the latest in a series on hard drive manufacturers slipping SMR technology into existing disk lines, with little or no notice to customers. In very brief, SMR disks generally perform well enough in light storage workloads, with plenty of idle time between storage requests—but they can fall catastrophically flat on their faces when hit with more demanding workloads. Although all three remaining major hard drive vendors—Western Digital, Toshiba, and Seagate—have "submarined" SMR disks into existing channels without doing much to notify customers about it, only Western Digital has done so with disks designed specifically for NAS, or Network Attached Storage, use. Unfortunately for Western Digital, NAS users tend to be significantly more technical than general consumers—and they frequently hit their disks with far more difficult workloads than Western Digital apparently tested or planned for. There's also a Red Pro line targeted to maximum-performance applications. This line is unchanged—it existed with the same branding before the SMR fiasco, and it still exists with the same branding and same models today. Western Digital doesn't publish details about the CMR cache area in its product datasheets, unfortunately—but typical estimates, such as what was shown in this blocksandfiles interview , range from 1GiB to GiB, depending in part on the size of the disk itself. The CMR cache area on the drive will perform the same as an entirely CMR disk does—and if it has "downtime" between storage requests, the drive's firmware can spend that time reading data from the CMR cache and trickling it down to the considerably more limited main SMR storage area. Once permanently stored in the SMR zones, the data can be read at about the same speed as it would be from an equivalent CMR disk—SMR's performance limitations are strictly bound to writes. If you never committed enough write operations at once to overflow the large CMR cache area, and you gave the drive extended amounts of idle time to "breathe," you'd see no performance difference between CMR and SMR disks—although, as some NAS users have commented, "you can hear them running all the time.

You can withdraw your consent at any time. The latter has better performance and a longer warranty which makes it essentially a larger version of the FireCuda. Install the app.

Would you recommend the Red or the Red Plus drive? The most important thing is HDD writing technology. With a 2-bay NAS these drives are either merged together or mirrored. This way it has no issues with RAID rebuild speeds. Anything above drives will cause issues.

Western Digital originally launched their Red lineup of hard disk drives for network-attached storage devices back in These drives have traditionally offered very predictable performance characteristics, thanks to the use of conventional magnetic recording CMR. More recently, with the advent of shingled magnetic recording SMR , WD began offering drive-managed versions in the direct-attached storage DAS space for consumers, and host-managed versions for datacenters. There was no fanfare or press-release, and the appearance of the drives in the market was not noticed by the tech press. Almost a year after the drives appeared on the shelves, the voice of customers dissatisfied with the performance of the SMR drives in their NAS units reached levels that WD could no longer ignore.

We want to thank our customers and partners for your feedback on our WD Red family of network attached storage NAS hard drives. Your real-world insights shared through in-depth reviews, blogs, forums and from our trusted partners are directly contributing to our work on an expansion of models and clarity of choice for customers. Please continue sharing your experiences and expectations of our products, as this input influences our development. From our experience, we see most SOHO users rely on their systems for office file sharing, home backup or content archiving. Throughput and idle time are key considerations in these types of SOHO workloads. As explained in our post on DMSMR , as well as in media reviews, these drives prefer idle time to perform background operations, without which the drive may take longer to complete a command. Our use-case analysis shows that SOHO workloads typically are based on short periods of access to the drives. While test results can vary from one methodology and test bed to the next, we acknowledge that in some cases DMSMR, for the idle-time reasons covered earlier , can result in slower rebuild times. The explosion of data seen today has spawned a spectrum of NAS uses cases, as well as increasingly demanding applications. One of those includes use of ZFS, an enterprise-grade file system.

Unfortunately for Western Digital, NAS users tend to be significantly more technical than general consumers—and they frequently hit their disks with far more difficult workloads than Western Digital apparently tested or planned for. It might make more sense to opt for a smaller capacity drive with a lower cost per terabyte than a larger, more expensive drive with excess storage you will not fully utilize.
