Hitachi is the best choice for notebook hard disk, and Western Digital is quite acceptable.
There are two kinds of notebook hard disk speeds: 5400 rpm and 7200 rpm. Generally, 5400 rpm is enough.
The normal thickness is 9.5mm. At present, the hard disk of Ultrabook is 7mm, and some large-capacity ones are12.5mm..
Toshiba's notebook hard disk is divided into three suffixes: GS GSX GSXP. Only the quality of GSXP can do it, but this is only for OEM.
As for the product quality of GS and GSX suffixes, it is not particularly recommended [Toshiba original 2.5 mobile hard disk is also the former]
Samsung's notebook hard disk has many products through improper channels, and the warranty is also difficult.
Toshiba and Fujitsu are prone to puzzling problems, especially C4 and C7 in the hard disk S.M.A.R.T
Seagate products are even less recommended! Because Seagate's various home-grade hard drives now have various problems!
Therefore, I also suggest not to buy notebook hard disks of Seagate, Samsung, Fujitsu and Toshiba brands ~

Reasons for choosing Hitachi (HGST): [Note: Hitachi was renamed HGST due to the acquisition]
Hitachi (now renamed HGST)* due to acquisition * (the best notebook hard disk in the world) is common.
IBM is the inventor and creator of hard disk, with many patented technologies. But later, the glass disk encountered a very high repair rate, and for other reasons, the popular IBM hard disk was forced out of the market. Hitachi bought IBM's storage department, and officially launched a brand-new hard disk brand in June 5438+ 10, 2003, which is today's Hitachi hard disk. Recently, a single disk 1TB desktop hard disk and a single disk 500GB ultra-thin notebook hard disk have been introduced, and the performance of these hard disks is very good.
Western Digital (WD) (the most stable and best-selling desktop/notebook hard disk in the world) is more common.
WD Company was founded in 1970, and its headquarters is located in Forest Lake, California, USA. It is one of the oldest hard disk manufacturers and one of the founders of IDE interface. WD Company mainly focused on IDE field after 1999 withdrew from SCSI market. In the last six months of 200 1, its sales reached1015 million dollars, and maintained a profit of 33 million dollars. WD Company is a company that is not good at publicity, and there are only a handful of unique technologies that people can remember. In fact, WD's technical strength should not be underestimated, and its hard disk performance has been at a high level for a long time, so it must be supported by advanced technology.
