You told us on 5th of November that "HP and Dell provided supporting quotes in the Seagate release" of the latest Savvio lineup so it simply has more capacity than the 10K.2.

"The supplier isn't named." Probably an Enigma Virtual Machine.

i was wondering what's so special about 300GB as ive got a 500GB 2.5" esternal sat here...

the difference is:

500GB / 5400rpm / sata / not rated for 24/7/365 use

300GB / 10000RPM / sas / rated for 24/7/365 use

the extra platter used in 500GB sata disks generally rules out 10Krpm use becuse of the extra air firction caused bu the second platter which means more power used and even more heat to try and shift : just look at the 300GB WD raptor for a good example of this: 2.5" dual platter 10KRPM mounted into a huge heatsink that transforms it into a 3.5" drive just to try and keep it cool...

With a 10K RPM drive you have an ave. 3ms rotational delay, with a 15K drive it's 2ms. I wonder how they make the 10K drives have a lower latency? Using 2 head towers?

The 300GB-10K drives are enterprise rated SAS, specifically engineered for high performance , high duty cycle applications not the sort of things you would typically throw at SATA technology.

The point of FATA which EMC also use as LC-FC was to seamlessly integrate low cost SATA technology into existing FC infrastructure. Neither SAS nor SATA solve that problem since they use a different interconnect whichrequires different enclosure's meaning additional cost, re engineering, stranded capacity, limited scalability etc

I tried posting a comment on the Server Insights blog asking why this HP drive would be anything new or special, considering SFF drives that large and larger have been on the market for I think a couple of years. So far, the comment has not appeared, and there are no comments on any other item in the blog either. Anyone else want to try? I'm getting a sneaking suspicion comment "moderation" means "deletion" :-(
