I have a PC with a single 6Gb/s SATA port, I have a 7200RPM HDD that is my primary drive (i.e. the OS is installed on it), I also have an SSD (450MB/s Sequential R/W, 85K Random Read, 55k Random Write) that is going to be used as a Data drive for my visual studio projects.
Which is more beneficial to be plugged into the 6Gb/s port? Will I notice significant OS slowdown running the HDD (with OS) from another port vs the 6Gb where it was originally?
Both are SATA 3 (6Gb/s) capable drives.
I assume both devices are actually SATA III devices? – Ramhound – 2013-12-16T14:46:01.927
I think so. One is a Seagate 7200.12, the other is a Kingston SSDNow v300 – Obsidian Phoenix – 2013-12-16T14:49:52.250
1Feel free to confirm by researching both products and finding the product specifications on the Seagate and Kingston website. People have ran operating systems on much slower then 3GB ports for years. Its unlikely you could even match out the transfer rates on either device. Your SSD performance will drop by about 50% on the SATA II port, what you should determine is if, that performance decrease is something you can accept. – Ramhound – 2013-12-16T15:14:34.603
Yeah, both definitely appear to be SATA 3 according to the specs. I'm installing this to drop Visual Studio build time from 20-30 minutes, so I would probably prefer to have the SSD as faster. It sounds like I won't notice too big a difference having the HDD on a slower port. – Obsidian Phoenix – 2013-12-16T15:21:00.540
