Difference between SATA I, SATA II and SATA III

SATA I  (revision 1.x) interface, formally known as  SATA 1.5Gb/s , is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s.

SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.

SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.

2:As different platform or software, the result will be a little difference(we usually use CrystaDisk and AS SSD Benchmark test Our SSD)

3: As we are factory and we use 1000KB=1MB for easy calculate, also we use a little space as the Bad Bolck Management software for SSD's stable using, the real capacity will be: Capacity x 0.93, Pls notice that all of the SSD must have the Bad Block Management sofeware for its running well

4:As our SSD is new and just out of factory, maybe you will found the SSD can not be seen in "My computer", pls right click "My computer-Management-Device manager-disc drive"  and see if can find our drives. Pls do the format and partition and use the SSD as the main disk but not slave drive or connect to USB device in the first time
