    Drive Name Size Capacity RPM Interface
    Ultrastar C15K147 2.5 73-147 15,000 SAS
    Ultrastar C10K300 2.5 147-300 10,000 SAS
    Ultrastar C10K147 2.5 73-147 10,000 SAS

    No SATA interface. Though it shows that is possible.

    Fujitsu has had a 147Gb 15,000rpm 2.5" SAS drive out since June of 2008

    I heard they got extremely hot though, with there 8.8 watt power consumption.
    Seagate also had a 73gb 15K.2 2.5" drive but It had bad firmware

    Even if they were SATA, they will not work in laptops, because they require a 12V line for operation.
    I had my eye out on the Hitachi Ultrastar C10K300 model, but the velociraptor seemed a better buy at 10K. These new 15K drives sound good for my homemade laptop project. Drool - SAS :D

    I just need to figure out what I am going to do with all of my 3.5" 15K drives from Fujitsu, Seagate and Hitachi :eek:

    I am actually surprised these drives havent become commonplace in the past. 15K platters have to be small in diameter to resist the exploding factor. I guess 15K motors havent advanced as fast, since those 15K motors are really small.

    Oh yeah, 15K drives need to be actively cooled, my 3.5" drives get quite toasty without a fan on them

    Those are designed for server, not laptop use. Put one in a laptop (assuming you can even get it to work), and you'll overwhelm its thermal capacity --probably even distort or melt the plastics.

    It would be kind of like trying to remove Western Digital's Velociraptor drive from its heatsink mountings and put it in a laptop. Bad idea.

    Actually, the Velociraptor runs fairly cool. It doesn't need the heatsink, that's there mostly to fit into the desktop's 3.5" slot.

    It really is remarkable how persistent these misconceptions are, but needless to say, one of the aforementioned HDs can be put into a laptop.

    You have a laptop with SAS support? All of the Hitachi 2.5" drives are SAS.

    That makes more sense :p

    But yeah, server-grade 2.5" 10000+ RPM drives have been available for years, yet they've never filtered down to consumer-grade technology beyond the WD Raptor series, and now that we have SSDs that kick the crap out of these drives in terms of performance, I don't expect they ever will.

    What he said.. Moding lappy's is for the true Gangsta's...

    Or.. pay the same money for an Intel SSD.. with MUCH better read and write times.. MLC of course.. but the disaster recovery of a 15k rpm drive is going to pencil out to similar recovery number as an Un-Recoveralbe SSD.

    IMHO..

    But great info..

    Thanks, JW

    What does the Birtsh SAS or James Bond have to do with a 15k rpm HDD?

    Thats just crazy talk.. :D

    Be well, JW
