Hello,
Just purchsed SSD to replace my main HDD on my vostro 3560 laptop.
I wish to replace my optical drive with my current HDD using caddy.
What sata support the caddy should have? the ones on ebay have sata (1) support from the description and they cost around 10$, on the other hand on hddcaddy the caddy with sata 3 support cost way more.
my current hdd connected with sata2, but the question is what sata is there on the optical drive connector.

Thanks in advance.
