This week, Western Digital announced a slew of new hard drives. These drives are set to slightly increase capacities over today’s drives. Still, it is a move in the right direction for the company, even if it is showing how slow innovation has become in the hard drive space as the market participants dwindled.
WD Ultrastar DC HC570 22TB and Ultrastar DC HC670 26TB Drives
WD has two new drives for the data center space. The WD Ultrastar DC H570 is the company’s 22TB drive that uses CMR. The WD Ultrastar DC H670 is the company’s SMR drive that allows for 4TB more to be stored or roughly 18% more at 26TB total capacity.
Both drives use OptiNAND technology as WD tries to integrate NAND into its hard drives to improve performance. The SanDisk merger and business have been under fire recently with activist investors suggesting the merger has failed and the company should be split despite the use of OptiNAND in the hard drive segment.
WD 22TB Red Pro, Gold, and Purple Pro Drives this Summer
In the announcement, Western Digital also said that the 22TB drives were spanning across its portfolio. That includes a 22TB WD Red Pro, and a 22TB Purple Pro, and a 22TB WD Gold. The NAS segment is serviced by Red. Gold is for integrators. Purple Pro is for video surveillance. These drives have many of the same features such as OptiNAND as the data center drives.
Really what is happening is that WD is putting out a new base drive model, and then seems to be using firmware, marketing, and maybe some binning to make different drives at different price points.
One way to look at this is that we get larger hard drives. Another way to look at it is that these drives are only 2TB larger for the CMR segment. This is even with the 10 disk hard drive design, ePMR, and more to the 22TB figure.
That is a 10% generational jump and really highlights the lack of competition and resulting innovation in the hard drive space. Years ago, each generation would be more like 50% larger capacities while also being faster, but once WD and Seagate were allowed to purchase rivals, the market consolidated and thus we get small gains.
The big question now is the workload ratings these drives would get. We already addressed the WD Red Pro 20TB Launched with Wickedly Weak Workload Rating only a few months ago and that we addressed in the workload rating video:
If these end up being released later this summer with 550TB/ year ratings, these would be slightly worse.
