    I have a Dell Studio XPS 1645 (Intel i7, 4GB DDR3, ATI HD4670 1GB, 16" RGBLED, Win 7) and wonder if it is possible to put the Seagate Momentus XT Solid State Hybrid Drive 750GB in my computer? At the moment I have a Seagate 500GB drive (model number: ST9500420ASG). Does my computer support the 750GB hybrid drive? The dimensions seem to be almost the same. I would really appreciate if someone could help me.

    I'm pretty sure all the Seagate Hybrid drives are standard 2.5", 9.5mm. It should be fine in the SXPS 1645.

    SATA standards are backward-compatible, and "hybridness" of the hard drive is transparent to the BIOS and the OS.

    I have been using a Seagate Momentus 7200rpm 500GB hybrid drive (SATA 3 Gbit/s) in an Inspiron 1501 (supporting SATA 1.5 Gbit/s), in place of the original a Seagate 5400rpm 120GB drive.

    According to the information on Seagates website the dimension on my current drive are:
    Length 100.35mm
    Width 69.85mm
    Height 9.5mm

    The dimensions on Momentus XT hybrid drive are:
    Length 100.55mm
    Width 70.10mm
    Height 9.7mm

    The hybrid drive has not the exact same size and on all dimensions around 2-2,5 mm bigger. Does anyone know if it still can be possible?

    only way to find out is plug it in, no way you can hurt anything :) You're even more careful than I am. Usually for customers I buy a 2.5in HDD/SSD and just drop it in, don't look for specs of the old vs new hahaha

    No, the dimension differences are around 0.5 mm only. The hard drive caddy is such that it can accommodate slight variations. The product manuals (like this one) do provide such +/- variations per product.

    As I said, I upgraded from a Momentus ST9120822AS to a Momentus XT ST95005620AS without problems.

    Of course you're right. I calculated wrong, but now I've tested and it works without problems. Have not used the hard drive more than a few hours, but so far it works well. Win 7 will start much faster and so far several of the tested programs. Can not really be compared with an SSD, but considerably faster than a standard HDD.
