Sata Transfer Speed. The interface itself runs at 15gb while the bandwidth throughput is 150mbs. Sata 3g doubled the speed to 300 mbs or about 3 gbs.

Via that connection most ssds will provide readwrite speeds in the neighborhood of 530500 mbs. The sata 3gbs revision only supports transfer speeds around 300mbs yet we saw transfer speeds up to 500 mbs with each cable that we tested. With protcol overhead and encoding you get a transfer rate of about 530 600mbytes.
The throughput is at 600 mbs.
Fast transfer speeds with uasp this usb to sata adapter supports usb 30 data transfer speeds of 6 gbps compatible with usb 20 and usb 11. The throughput is at 600 mbs. Its actual uncoded transfer rate is 12 gbits 150 mbs and it supports the communication rates of up to 15 gbits. Sata data transfer rate the sata i interface which was previously known as sata 15gbs is the first generation of sata design.
