Entering the 22TB generation, once again grabbed the first hair fragrance, providing 4 series of product choices.
Western Digital was the first to release 22TB hard drives in May. In addition to the Ultrastar DC HC570 enterprise-class model, it also announced that the same technology will be introduced into the WD Gold, WD Red Pro, and WD Purple Pro product lines, providing complete solutions for different application needs. .
WD Gold, WD Red Pro, and WD Purple Pro with a capacity of 22TB have now appeared on Western Digital’s official website. Interestingly, the reference price is US$599.99 (equivalent to about NT$17,940), but the official note also requires 3-4 Weekly time to be officially available. As for why are they marked $599.99? ! These products are originally from the same root, based on the same technology and then optimized and adjusted according to their respective application areas. From Western Digital’s point of view, the cost is probably quite similar. Of course, it is not ruled out that the data has not been updated.
Western Digital’s series of 22TB hard drives are based on CMR and ePMR magnetic recording technology, composed of 10 discs, 20 magnetic heads, and combined with HelioSeal helium filling packaging technology. They are also equipped with OptiNAND technology. In addition to the two or three things previously announced for structural design benefits, ArmorCache is now newly added, which can improve sequential and random write speeds. Taking the WD Gold 22TB as an example, its maximum transfer rate is marked as 291MB/s, which is about 8.x% higher than the previous product’s 269MB/s, which is a noticeable improvement.
WD Gold enterprise near-line storage, WD Red Pro network storage device, WD Purple Pro video surveillance three brothers, their respective positioning and functional division and other information, I believe everyone should be familiar with it, so I won’t go into details here. In short, Western Digital Taiwan branch is planning to introduce it, but the actual arrival time depends on the progress of the agent, let’s wait and see!
