Pros: Silent, very cool running, large capacity and good performance. It's obviously not a screamer at 5400 RPM but unless you're working with exceptionally large files you won't notice it in day-to-day use. I use Eclipse, Netbeans and Sparx Enterprise Architect and even on very large commercial projects (5000+ classes) it's impossible to tell whether I'm running them on a 500GB or 640GB 7200 rpm Samsung drive or this 1TB drive. The only way you'd know it's slower is to measure it very precisely because on small/medium sized files the difference in speed is going to be found to the right of the decimal point.
Like I said, they're doing their "disk" performance testing with a large RAM-based disk cache enabled in the computer. That doesn't measure the speed of the drive, it measures the speed of RAM and software. It's not unreasonable, since RAM disk cache is fairly standard, but it's cheating with regard to rating the performance of the disk.
The true performance of a disk is measured with a setup that exercises the disk, not memory. Modern disks have internal cache in the drive, but it's typically 64MB or less, not 500MB or 1GB like a RAM-based disk cache can have.
The reason that difference matters is that if you're running a lot of programs concurrently, you can't allocate lots of RAM to the RAM-based disk cache, or else you end up swapping running tasks to disk, in which case you're even worse off than before.
You can spend another $40-80 on more RAM (assuming your mobo can hold it) but then you've lost the cost advantage of the "cheap disk".
Lesson: There is no such thing as a free lunch.
