The higher the speed of the hard disk, the better?

After understanding the speed of the hard disk, now the problem is: the higher the speed of the hard drive better?

The hard disk speed refers to the disk in the disk set up in the rotation of the number of disks per minute, the unit is r/min, generally speaking, the higher the speed of the hard disk, the faster the read speed of the hard disk.

General desktop hard disk has 5400 to/min, 7200 to/min, 10000/min and 15000 to/min specifications, the current desktop computer hard disk 7200 Turn is the mainstream, 5400 to basic exit the market, and 10000 turn above are SCSI and the latest SAS hard drive, Mainly used in the field of server hard disk.

The current notebook hard drive 5400 turn is still mainstream, but now buy new notebook hard disk, many start to use 7200 rpm.

The higher the speed of the hard disk, the better? Theoretically, the higher the speed of the disk is better, but the higher the speed of heat, and shorter life, and the notebook hard disk due to small size, at present good can be done in 7200 turn under stable operation, and then a high bottleneck, In addition, the general hard drive standard 5400 or 7200 RPM is only theoretical speed, the hard disk in practice, in order to avoid excessive speed effect of heat dissipation, the actual speed will be lower than the speed of some of the notes, we can think of the hard disk in the speed of the note refers to the maximum speed of the hard disk, generally normal work, the speed is lower than this.
