Western Digital began shipping its first 22TB and 26TB hard drives

The death of hard drives was predicted by experts ten years ago.
We were told that SSDs would soon displace hard drives not only from home computers, but also from the cloud sector.
It was assumed that the price per 1 GB of SSD would continue to decrease, which would have a positive impact on the cost of super-capacity drives, and 10TB would enter every computer by the year 2020.
It is not clear what is the reason for the current stagnation, because SSDs have been getting cheaper lately, and predictions of the displacement of hard drives have disappeared from the information field altogether.
It is possible that the case in the semiconductor deficit, which had a negative impact on the plans of manufacturers to increase the volume of SSDs and their capacity.advertisementHowever, but the alternative to traditional hard drives still do not.
It is obvious that many cloud services, for which are important not only reliability, but also speed of access, have already moved to the SSD, but quite a few remains faithful to the HDD.
Not only that, but the three companies involved in the production of hard drives do not plan to give up their positions.
In contrast to SSDs, the capacity is growing, which allows you to buy one hard drive to cover the requirements for home video and photo archives for decades to come.
Western Digital announced the HDD capacity of 22TB and 26TB, which are based on CMR recording technology and are the only hard drives on the market with 10 platters at once.
Commercial customers may want to consider the DC HC570, which is part of the Ultrastar series.
It's more suitable for cloud storage and data center applications, with increased durability compared to the custom Red Pro, Purple Pro and Gold series.
Each platinum has a 2.2TB capacity, with Western Digital promising the new drives will go on sale freely this summer.The 26TB HDD, on the other hand, is a data center series.
It also has 10 2.6TB platters, which are written using SMR technology.
Only one DC HC670, the flagship of the Ultrastar series, is available for order.
Western Digital does not tend to disclose the characteristics of the new series of hard drives, so more details we will learn from enthusiasts, who will receive such drives first.
It is known that all new items have the OptiNAND caching technology.
It implies tangible write acceleration for random and large blocks.
According to the official data, blocks of 256 KB can be written 40% faster.
As for blocks larger than 1 MB, they will boost up to 80%.
Experts note that we are talking about peak values, which means that in many user scenarios we may not see any increase at all.
In general, large-capacity hard drives are valued not for their speed, but for their reliability and ability to work long hours under load in 24/7 mode.For the post rewardedThis material is written by a site visitor, and for it the reward is accrued.
