What’s the difference between Wellcore SSD SATA I, SATA II and SATA III?

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.

SATA II specifications provide backward compatibility to function on SATA I ports. SATA III specifications provide backward compatibility to function on SATA I and SATA II ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port.

Example: Wellcore W20 series 256GB SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to550/500MB/s sequential read and sequential write speed rates respectively. However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 160/160MB/s sequential read and sequential write speed rates respectively.

The advantages of Wellcore SSDs:
1) Original Intel/Micron Nand flash
2) High reliability,date stability
3) Low energy consumption
4) Faster read and write speed
5) Noiseless,light-weight

Moreover,Wellcore SSD are being tested by professional benchmark and environment testing,super quality and great service had attracted many customers overseas to place order!
