I would have to say that it surpasses it.

I'm going to have to buy a few of these for my next build.

thanks for your reply !!

I found this on a forum (about the black)

126.5 MB/s avg. read (148.69 MB/s max.) and 80.62 MB/s avg. write (105.78 MB/s max.).

and this is my old raptor

so would you say it beat my raptor ? i honestly don't really know anything about HD benchmarking but as you said it does seem like it..

however from the link you posted, if I divide all speeds by 4, it's not as high.

The benchmarks shown are the recorded speeds for four drives in a RAID 10 array. You can't necessarily get individual drive performance by simply dividing by four, as performance will be determined by other factors as well, such as the RAID controller used.

If you want to compare single drive performance, you really need to compare single drive benchmarks.

I see, if I look at WD's datasheet they say that the data transfer rate (sustained) is 150MB/s, which is higher than even the 2tb which has 138 or the 1tb which has 126, basically its the highest one of all blacks, does that mean it's faster than the 2tb ? is the data transfer sustained rate the speed of the drive ?

thanks again for all your answers so far guys
