Product Description

Definition of Solid State Drive

Solid State Drives, which use flash memory instead of a hard-drive platter to store date.

Old computers had a habit of spitting files and spreading the parts all over your hard drives, but modern ones don’t do this as much. Not even close, a bimonthly pass with a capable Defragger can help you maintain peak performance on a heavily used hard drive.Data transfer to and from solid-state drives is much faster than electromechanical disk drives. Seek time and latency are also substantially reduced. Users typically enjoy much faster boot times as well.

In general, SSDs are also more durable and much quieter, with no moving parts to break or spin up or down. SSDs do, however, have slower write times and a set life expectancy, as there is a finite number of erase/write cycles before performance becomes erratic.

Advantages of Solid State Drive:

1. Quick response and high read/write speed

2.Silent mode 

3.Low power consumption and low heat.

4.None mechanical breakdown

5.Can work under wider range tempreture, 0~70℃

6.Lighter, smaller and more portable.

7.Shockproof and drop resistance.

Our products’Competitive Advantage:

1)Original brand NAND Flash
2)Fast read/write speed, faster application load times
3)High reliability, data stability
4)Low energy consumption
5)Anti-shock, anti-dust, noiseless, superior security
6)Shockproof, rugged design safe and high stability and reliability
