Please format the SSD first before you use it according to the video we show,if it still not working,please contact us drsctly,thanks!
1. Why I bought 64GB USB, but the computer show it is about 58GB?
Because:
. Flash memory producers are using decimal arithmetic:
1KB=1000Bit, 1MB = 1000KB, 1G = 1000MB
‚. Calculated, the operating system using binary arithmetic:
1KB=1024Bit, 1MB = 1024KB, 1GB = 1024MB
And there is a hidden flash area occupy some capacity.
That is why there are some differences between display capacity and nominal capacity of flash memory product.
8GB = approximately 7.4GB-7.6GB
16GB = approximately 14GB-15GB
32GB = approximately 28GB-30GB
64GB = approximately 58GB-60GB
128GB = approximately 120GB-125GB
What is 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 muchfasterthan electromechanical disk drives. Seek time and latency are also substantially reduced. Users typically enjoy much faster boot times as well. In general, SSDs are alsomore durableandmuch 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.
