|Windows 7 Home Premium will take up a little more than 20 due to recovery partition, also take into account the SSD usually has less than advertised space because some space is set aside for the controller. Now in the case of the Force Series, I believe they take this into account (thats why they have a 120GB drive and the competition has a 128GB drive, the 8GB is not available on the competition drive so they are actually 120GB). |
You'll also want to put some applications on there I'm sure. I don't know if all you do is game, but things like photo/video editors that have to open large files, as well as things like Office are nice to put on there as well. If you aren't interested in all that (or are interested in saving $) then the 60GB will probably be fine. I was just offering some thoughts.
SATA III is just a protocol that allows for higher data transfer rates. So, if you had a drive that could transfer over 300mb/s (3GB/s is the SATA II limit) then you were getting bottlenecked before by SATA II. That wasn't ever a problem, because most platter drives, even 10k Velociraptors, can't break past 200mb/s even in RAID configurations. However, new SSD's actually can break the 3GB/s bottleneck, and hence make good use of the SATA III connection. The 7200RPM drive is going to go as fast as 7200RPM drives go, whether its SATA II or SATA IIIII. In the case of your SSD, it uses a Sandforce controller which peaks at ~285mb/s, so SATA II is fine. Honestly, even the new SATA III SSD's make some concessions to use that speed, and I prefer the balance and value of the Sandforce models too (which the Force series obviously is).
I also just noticed you're rocking the P67 Pro with a non 'K' series i5 2500. Was this intentional? The P67 boards are designed for overclocking, but there is very little overclocking to be done if your CPU isn't the 'K' series, as the multiplier is locked. You could probably switch to an H67 in that case, fine motherboards just weren't designed to overclock.
