Although the prices of SSDs are falling more and more, HDD drives are still irreplaceable for storing more data. That is why many companies are striving to provide the fastest possible transfer and hybrid solutions that incorporate both technologies, which feature new interfaces.
During the Computex fair, Western Digital unveiled a completely new SATA Express drive, based on the same solution used in the WB2 Black, but with a much faster interface. This allows the computer to communicate with very high speed.
So big that with a 695 MB / s transfer rate, the drive lags behind typical SSDs, as it bypasses the limited SATA 2 bus capable of transferring data at a maximum speed of 550 MB / s. The drive is of course a hybrid and consists of a 4TB HDD disc with a 128GB SSD installed on which the most used data is stored.
