I just posted the article Seagate introduces 15,000 RPM 2.5" SAS hard drives.

Seagate has introduced its first 2.5" Savvio 15,000 RPM Serial Attached SCSI (SAS) hard drives, which it claims to be the world’s fastest hard drives, according to Tom’s hardware Guide. …

“10% faster seek” Is not much of an improvement, and 10% faster than what? Seek times are the most important, not rotational speeds.

dude, its SAS…the seek times must be insane with only a 2.5" platter! newegg has the 3.5" 74Gb 15k SAS seagate, here are the specs: Performance Interface Serial Attached SCSI (SAS) Capacity 74GB RPM 15,000 RPM Cache 8MB Average Seek Time 3.5ms Average Write Time 4.0ms Average Latency 2ms http://www.newegg.com/Product/Product.asp?Item=N82E16822148080 so if the 2.5" is 10% faster that means a 3.15ms average seek time…now if only they made laptops with SAS :X

crap, double post, my bad, the new layout dosen’t seem to have an edit button either, so if a mod could delete it for me that would be awesome, thanks

Well, if you add the seek and latency times of the 3.5" drive, assuming they are “random” times, (not at the outer edge) that puts it about on par with a Raptor for access time. So, a “10% improvement” is still not a huge leap and would not be readily apparent in normal use. The sustained transfer rates are probably insanely fast, but I’ll take fast access times anytime, for basic desktop use.

i hate this new layout… :+

sorry, but SCSI is not designed for “normal use”, this thing is gold for servers, its smaller, uses less power, less heat, higher MTBF, and to top it off its slightly faster (only downside is the price will probably reflect the improvements :S )
