    Hi, :)

    I am searching for a nice 2.5'' HDD or SSD for my sandy bridge laptop.

    I want the best performance/price ratio.

    What I see now :

    1. Seagate Momentus XT 500gb
    2. Crucial C300 60gb + WD carviar black 320gb

    I don't want to spend more than 300$ on a hard drive.

    Also, does 2.5'' SataIII 6Gbps HDD will be release soon? Will it be faster??

    Does a SataIII version of the Momentuse XT is in prevision?

    Thanks a lot!

    There is currently no reason at all to release a SATA III (6 Gbps) HDD, because the speeds that a 2.5" HDD can reach don't even come close to passing the limits of a SATA II (3 Gbps) interface. The best 2.5" HDDs reach about 180-200 MB/s (1.4-1.6 Gbps) which barely saturate a SATA I (1.5 Gbps) interface, let alone a SATA II (3 Gbps) interface. As for a faster version of the Momentus XT, there have been no hints so far of any successor model at all.

    As Judicator has stated, hard drives don't come close to saturating SATA 2. If you get a SATA 3 SSD like the ones from Crucial you might get close.

    As people have mentioned, getting a SATA-3 mechanical HDD will show no performance improvements over the SATA-2 mechanical HDD's that are available today.

    You'll really need to get into SSD's in order to see any benefit from SATA-2 --> SATA-3. And in that regard, wait about a month. Intel 3rd generation drives are coming out soon, as are SandForce SF-2500 drives. You should start seeing SSD's capable of SATA-3 coming into high supply around that time.

    Until a mechanical drive surpasses the 3.0Gbps mark (most don't even surpass the 1.5Gbps mark right now)...

    There will never be a purpose to it i dont think.

    I think standard winchester drives will be over 2 tb at that time.

    So, the best way to go is a SSD/HDD combo?

    Will a better hybrid with more SSD space be release some day?

    Thanks a lot!!

    I bought a 500 GB MomentusXT drive and it was a big letdown IMO. The boot times weren't a whole lot faster, and it isn't exactly "cheap" being 120~ for 500 GB 7200 rpm drive, you can pick up a WD5000BEKT for 60-70 bucks.

    Indeed. Bought 3 of these and they are VERY good drives. Sure, they don't boot as fast an SSD, but once you're at the desktop, the OS is nearly as snappy as an SSD. So if my SSDs ever die prematurely, I'll be OK using these as an OS drive.

    or just get an ssd, and have a networked 3.5" storage. a nas, or winhomeserver or what ever. cheap massive storage pool + very fast ssd in every pc in the home == sorted save huge storage pool + very fast systems.

    but else, yes, why not ssd/hdd combo if you need the space. i'm happy with 160gb on my laptop actually.
