Speed of the hard disk

Hi all, I'm planning to buy a new PC from DELL, a Studio XPS 9100. It comes with this hard drive;

1TB - 7200RPM, SATA 3.0Gb/s, 16MB Cache

I don't know which brand it is, but I have the tech specs.

I want to install Windows on a SSD drive i would buy, here one I have spotted;

Kingston SSDNow V Series Gen II 64GB 2.5IN SATA2 Solid State Disk Flash Drive (http://www.kingston.com/ssd/v-series.asp)

The problem is, I don't know how to compare the first drive to the second in terms of read/write speeds.

I know the SSD has this : 64GB – 200MB/sec. read; 110MB/sec. write, but how I can compare this to a SATA drive?? What means the SATA 3.0Gb/s???

SATA II is rated for 3.0 GB/s, meaning 300 MB/s. Keep in mind those are MAX speeds and your sustained throughput prolly wont be near as high.

I've never used SSD, but found plenty of info on the drives last I looked on google. I mean as far as the pros/cons and how SSD drives work. There's some difference in a spec of a SSD if I remember correctly...
