At the recent innovation day, Western Digital announced a large number of new SSD and HDD Hard disk products, of which the maximum capacity was 26tb. Ultrastar DC hc670 achieved a single disk capacity of 2.6tb and 10 disk packaging capacity of 26tb by relying on a variety of technology upgrades. However, 26tb HDD Hard disk is not the focus of Western Digital, and even 30tb is not rare. Western Digital executives hinted at the press conference that they already have 50tb + HDD Hard disk, although it has not been officially released, this super large capacity hard disk is not difficult, and the launch time is "just around the corner"**
Western mathematics suddenly understood alien technology and mastered the new technology of doubling the capacity when squeezing toothpaste with HDD capacity? There are some ways to say this. Pay attention to the name of this 50tb hard disk. Western Digital uses archival storage to describe it.
For the 50tb hard disk of Western Digital, there are two guesses at present, one is that Western Digital has remanufactured 5.25-inch discs, which can greatly increase the capacity, but this possibility is very low, because the 5.25-inch discs have not been mass produced for almost 20 years, and have long been eliminated, so it is impossible to rebuild the production line.
Another possibility is that Western Digital uses 20 disc technology on the existing 2.6tb discs, so it can achieve 52tb capacity on the current 26tb capacity, and it is not difficult to achieve the goal of 50tb +**
Compared with the current 10 disc package, the 20 disc package will obviously significantly increase the thickness of the hard disk, resulting in incompatibility with current devices. However, don't forget that the hard disk of Western Digital is used for archiving, not for thermal data. It should compete with tape drives, so indicators such as volume and weight are not a problem.
