They get something like 100MB/s average read/write rate, IIRC. There are things that beat them, like Samsung Spinpoint F1 1TB or Velociraptor (120 MB/s). However, the Spinpoint F1 is less reliable and the Velociraptor has a horrible price/GB. Yeah, I guess those two WDs are what I'd buy these days.
BTW, the average read/write rate is the most important benchmark when you deal with large files (videos, databases, games, etc.). If your PC is going to work with lots of small files (say, editing photos) then a Velociraptor would help a lot and may be worth it.
well i have a seagate 7200.11 t.5tb drive already, but was planning on using that as media storage, and wanted to get a faster drive for my OS and applications (possibly the vraptor) .... so what would you recommend for that?
If you value speed more than space, and can afford the velociraptor, then get it.
If you prefer something with lots of room and best bang for the buck, choose between WD WD6401AALS, WD WD1001FALS, and Seagate ST3640323AS (640GB). At newegg they all have the same price/GB, better than all other sizes, and they're all about the same speed. The WD6400AAKS is also excellent, with 90 MB/s average rates and only $70 for 640GB instead of $80.
Unfortunately that site hasn't been updated in a long time. Looking at average read "begin" numbers, and eliminating the top 14 drives because they are all SCSI, we end up with the old Raptor 74 GB leading at 71.8 MB/s. That's not really impressive any more. If the site was up to date, I think that 74 GB drive would be #40 or so.
I am also disappointed that www.storagereview.com has not been that active, and particularly that the performance database does not get updated regularly. They had a review of an early sample which was very positive. It does show some nice improvements of the VR outer ring transfer rate. It also compares the perflrmance to the very good WD AAKS series: http://www.storagereview.com/WD3000BLFS.sr?page=0%2C2
oh ok... so would u think that a vraptor would show a significant increase in perfromance considering the price? I can get 2x WD2502ABYS and set them up in raid for cheaper than a 150gb vraptor.... would that be faster?
I would agree with aevm. All the 7200rpm drives have similar performance.
If you want the best among them, look at one of the larger 1tb drives, and plan on using only 5% (50gb) of the space. The outer rings of a drive are denser, so the transfer rates are better. Also, limiting yourself to 5% of the drive's space will reduce the seek times, because the access arm has much less real estate to traverse. If you want, partition off 50gb for the OS and use the rest of the space for infrequently used data like backup.
The OS drive wants to do lots of short reads and writes. The velociraptor excels there. Raid-0 does well with large blocks of sequential data; a much different pattern.
There is generally no real world(vs. synthetic transfer rate benchmarks) performance advantage to raid of any kind.

There are some specific applications that will benefit, but
gaming is not one of them. Even if you have an application which reads one input file sequentially, and writes
it out, you will perform about as well by putting the input on one drive, and the output on the other.
The WD2502ABYS is faster (112 MB/s), but $70/250GB is bad IMO. The WD5001AALS is almost as fast and you get twice as many GB/$ ($75, 500GB). Also, the WD6401AALS ($80, 640GB) beats the WD5001AALS in both speed and price/GB. (All prices current at Newegg.)
