hi, was wondering if with a new sata 3 ssd if i would need a sata 3 cable? the cables i got i know are sata2 but wondered if id loose some performance if i did'nt buy a newer sata cable
SATA 2 cables should work at SATA 3 speeds unless they are poor quality.
Benchmark your SSD with ATTO benchmark software; if your Read/Write speeds are greater than 300MB/s then you know your cables can handle SATA 3 speeds.
