this product is only for HDD 2.5 not 3.5. you need a USB connector and e-sata, but the son is long so it is suitable even if they are distant.
It feeds well or a 2.5 SSd by the USB connection, but is not powerful enough for a 3.5 (you need an external power supply such as a dock or a box in this case, no external power can here) .
I do not get to boot the e-sata with either 2.5 drive but I think it comes from my bios.
Suitable for copying a disc HD and SATA 2.5 SSD, perfect for copying internal disk to an SSD before interchange. very good flow: copy about 70 GB on a 320 dd SATA Internal go to a SSD 240, 3 partitions, in less than 15 minutes with the software provided with the SSD. Picture perfect.
