Is SATA Cable Slowing Down Your Data Transfers? Max PC Investigates

Is your SATA cable slowing you down? Maximum PC investigates

We had a recent incident in our lab where SATA 6Gb/s performance inexplicably dropped going from one motherboard to the next. In theory, both boards should have offered the same performance on the SATA 6Gb/s port as both used the same south bridge chip in the board and the same SSD. When we couldn’t diagnose it as drivers or a mis-configured benchmark run, we decided to swap out the SATA cable for a “real” SATA 6Gb/s cable. Like magic, the performance went back to what we expected.

This got us wondering if there is actually a need to run “real” SATA 6GB/s cables with high performance SSDs. The official word from the SATA International Organization is no, not at all. The SATA I/O lays it out in its FAQ: “Question: Does SATA 6Gb/s require different connectors and cables to support the higher transfer speed? Answer: The same cables and connectors used for current SATA 1.5 and SATA 3.0 Gb/s implementations can be used to connect SATA 6Gb/s devices, although SATA-IO recommends quality components be selected to ensure data integrity and robust operation at the faster SATA 6Gb/s transfer rate. Keeping the existing SATA connector form factor enables SATA 6Gb/s to be designed into the same cost-conscious hardware architectures while minimizing infrastructure changes.”

I recently checked the SATA specs and like the article said, the cable specs have not changed. Just have to trust your vendor to supply quality cables. On my new ASUS motherboard they shipped a few 6Gbs cables that had 90 degree plugs with the locking clips. I have been getting all my cables from MyCableMart.com for a few years and they seem to have quality cables. I am sure there are other good vendors also.

SATA Data Cable Question
I just got some new SATA data cables. They have the lock on them which my old ones didn't. I put them on and I could still grab the sides of the cable and pull them off the drive. Should they lock and not come off unless I loosen the lock? Thanks, Coboc Model SC-SATA3-10-LL-BL-90 - Newegg.com

Sata/IDE to USB cable
I bought one of these today off eBay but then noticed the description says not comparable with vista and windows 7. But surely windows 7 should just find it on its own? Please let me know ASAP as I'm worrying I bought wrong one. Thanks kent.
