My first build. need ssd for os $100

would corsair force (CSSD-F60GB3A-BK) be good? $63

We need to know what country you are ? which website do you shop?

But I will recommend to buy like 102 GB/128GB of M4, Samsung 830, intel 330, Kingston HyperX 3K, SanDisk Extreme, and Corsair Force Series GT. And if you only install the win7(~20GB) and a couples of program in the SSD, 60/64gb should be fine. You can't fill up to 90% of the SSD, because it need some space to do the garbage collection and TRIM.

Get the one has the lower price of per GB/$.

I have alot of your same components (8150/Sabertooth,850PSU) - I was using an 120GB Intel 520 in my rig and couldn't have been happier. It's insanely fast, incredibly reliable and I had no compatibility issues with Windows drivers. The cherryville series is the cadillac of SSDs. CompUSA's site had them for $99 today, but I think they're sold out

I would recommend the Samsung 830 - they have all of the same pros as the Intel 520s, they're just a tiny bit slower of write speeds. They're usually in that price range and they're excellent - I have used them in nearly every laptop build I have done this last year and have yet to have one crash.

120/128GB is more than enough space for your OS/Programs. You'll never regret that choice, trust me

what about Kingston HyperX 3K 120 GB SATA III 6.0 Gb/s Solid State Drive SH103S3/120G ebay $100

I am using 3 of the same SSDs now these are Silicon Power Velox V60 2.5" 120GB SSSDs on Sata3 ports and their spec of 550 read and 510 write seems to be what I see, these were bought because the $99 price tag here (in Western Australia) made them very attractive proposition for my first SSDs, and am very happy with the performance of these drives.

If you can afford a 120 / 128Gb ssd get one of these as I have noted that space can disappear very fast with some applications such as Google Earth etc, also follow the guide "Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs" as this will help with space constraints.

When first installed here on the i3 PC that has 16Gb of ram I noticed that the bare windows 7 professional (64bit) installation used some 40Gb of the SSD space, following that guide I Turned Off the Hibernation File, Shrunk the Page File down to about 1Gb for compatabilty issues, I have after installing a few programs and run the SSD for some months now the space used is now about 20Gb on the i3 as well as the i7 I use.

Cheers Eddie
