After mechanical hard disk is SSD extrusion, a NAS network storage hard,solid mixture hard disk (SSHD). The former belongs to a special hard diskon NAS network memory, its application surface is narrow, sales did not open; the latter belongs to the enhanced version of mechanical hard disk,SSD characteristics have important, with large capacity hard disk andmechanical equivalent characteristics, sales increased year by year, the foreground is unknown.

In the current mechanical hard disk play still for desktop / notebook hard drive, their defects compared with the current SATA3.0 SSD most to the performance of. Even if they reach the same read-write speed, they will still be limited by its mechanical structure, can't really compete and SSD.

How to improve the capacity of mechanical drive, is the most important factor, desktop drives the current maximum capacity of 6TB, the maximum capacity of the notebook hard drive 2TB. And the recent acquisition of LSIhard disk giant Seagate flash / Master of business is worth paying attention,the master of this business also includes SF3700 consumption level / entrylevel.

In the face of near SATA3.0 limit performance of old products, new productperformance to icing on the cake. Consumption level of M.2 PCIe SSDsubject to flash P/E life, its performance did not meet the usersexpectations. Mechanical hard disk with large capacity able to breath, in the second half of this year, we may see the 6TB solid state hybrid drive figure.
