Hitachi's first five-disc 4TB 7200PRM desktop hard drive quietly shipped

Hitachi’s five-disc 4TB 7200RPM desktop hard disk “Deskstar 7K4000” released by the company earlier this year has quietly shipped.

The new Deskstar 7K4000 4TB is a standard 3.5-inch desktop hard drive, product number HDS724040ALE640, storage density reached 446Gb per square inch, 512e 4KB sector format, cache capacity 64MB, interface SATA 6Gbps, internal maximum data transfer rate of 1638Mbps (205MB/s) , Support 7×24 uninterrupted operation, idle power consumption 6.9W, typical noise 2.9 Bels.

It is the same as the previously launched Deskstar 5K4000, which has a maximum capacity of 4TB and uses a five-disc, single-disc 800GB design. It only increases the speed from 5400RPM to 7200RPM. I believe that with its high storage capacity and high performance, this year is bound to be favored by many enthusiasts.

The only thing unclear is why Hitachi still uses the previous generation of 800GB discs rather than the latest 1TB discs. The speculation here is that Hitachi can't guarantee whether the latter can have enough stability.

At present, the price of this hard disk is 28,800 yen, equivalent to about 2,388 yuan. Such a high selling price is estimated to be affected by the overall trend of the flood disaster last year. However, with the continuous improvement of hard disk supply this year, the price of high-end hard disk It will gradually decline.
