    I just upgraded my mac mini by replacing the stock HD (160 Gb Hitachi 2.5" 5400 rpm) by a Intel SSD for boosting its performance

    but for storage,

    i'm hesitating between replacing the superdrive with an optibay, the new drive would be a 2.5" 500 Gb 7200 rpm HD

    and an external enclosure with firewire and 3.5" 7200 rpm sata drive

    what would be faster between the 2 solutions?

    go for the internal route, firewire is fast but the HD bus speeds for the internal will still romp past it ;)

    Internal definitely. USB of FireWire are nowhere near as fast as SATA is

    thx guys

    i'm asking because my mini is brand new, keeping the warranty safe would be wiser at least for a few months...

    and i was wondering if in general 3.5" drives are faster than 2.5"

    so using the firewire would be useful to avoid removing original parts from my mini....

    thx again

    go for the FW

    My G4 mini ran noticeably faster booting from a FW400 3.5 inch drive than the stock internal one. FW 800 is plenty fast unless you are using some kind of high-performance RAID. I would recommend a 3.5" external to get more storage for a lower price.

    You can't really compare a 4200RPM pata drive to a 7200RPM sata one. The internal drive will be faster.

    the G4 is a very old machine, its HD is a slow IDE drive and cannot be compared to actual SATA drives...

    i'm looking for feedbacks about actual 2.5" internal sata vs 3.5 external sata via firewire
