    Is mine SATA or IDE?

    I am not sure whether to buy SATA drives or IDE drives after seeing this. In Notebook Hardware Control,it says IDE interface but I have been thinking I have a SATA interface in my Acer Aspire 5610Z. Could someone please tell me which one should I buy. Thanks.

    Isn't there a way that SATA can simulate a IDE port?

    'Best solution.'

    You're going to have to open up the laptop at some point, so just open it and check the plug, if it's PATA or SATA.

    Converters do exist but IMO it is pointless since it will revert to IDE speeds.

    I don't mean a converter.

    But on my SZ....without AHCI it runs at close to Sata speeds while its not actually "feeling" like a SATA connection...but is handled like an IDE connection.

    But apparently the OP has IDE - so that's the way he/she needs to go.

    Actually there are 2 SATA standards.
    1)SATA Gen1 150mbps
    2)SATA Gen2 300mbps
    PATA has 133mbps
    All the speeds are theoretical you never get close to these numbers.
    To get Gen2 you need Gen2 Controller and Gen2 Disk otherwise it will revert to Gen 1 speeds

    I know. And I get Read speeds of 245MB/s - thanks.

    But what does a SATA connector run at without AHCI?
    (Got a read speed of 228MB/s at that time)

    AHCI has a feature called NCQ.
    Just take a look below the diagrams are self explanatory.

    Quite inaccurate.

    Though you're correct about the physical aspects, NCQ is very much needed and used by SSD's for maximum performance; Intel's maybe more than others (they actually speed up with deeper Queues instead of slowing down, like other SSD based controllers do).

    Interesting. Stand Corrected.
    Anyway I feel that SSD is still not ready for primetime.
    I think filesystem layout has to change to better accommodate the way SSD operates.

    weinter,

    I agree with both your points (until I can test the G2 myself - to be sure).

    Possibly Win 8 may introduce this 'optimum to an SSD file system' in 2012, but I wouldn't doubt it may take a version or two (of O/S's) longer to get it right and get it mainstream over what we have now.
