    Replacing 5200rpm 2.5" SATA drive with 7200rpm 3.5" SATA Drive

    Does anyone know if a 7200rpm 3.5" SATA drive will work with the Streetdeck hardware bundle being sold? i.e Can I replace the included 5400rpm 2.5" SATA laptop hardrive with a 7200rpm 3.5" SATA drive? Has anyone tried it and had success?

    I tried popping in a number of different 7200rpm drives with no luck. The drive would start spinning up, then spin down, then spin up again...etc etc until the machine would finally turn itself off. I would think the 120watt OPUS power supply should provide plenty of juice for the drive.

    You might want to compare the power consumption ratings on the drives and see what the differences are. They should be printed on the drives in amps. If one is significantly more you may have some issues.

    Well, the 3.5" drive is going to draw off the 12v rail while the 2.5" drive will pull off the 5v rail.
    That's a huge issue if the power consumption is anywhere near the max of the 12v rail.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    I thought that the 3.5" pulled off of both rails, but I may be mistaken. Either way, it will put alot more draw on the 12V rail and the OPUS will likely not be able to power it.

    7200 RPM 3.5" drives draw a *lot* of power. I haven't put a meter on the streetdeck package, but I wouldn't be surprised if you are overloading the 12V line.

    Perhaps I can use this as an excuse to build one and replace my current SP13000-based system. ;-)

    I use a 3.5 sata western digital 200gb hard drive(7200rpm). It only use 9watts total for this hard drive when writing, and 8.75watts at idle. which means that of the 12v rail you draw 510ma and 575ma on the 5v rail. which = 6.12watts on the 12v rail and 2.875watts on 5v rail. which = 8.995 watts total for both rails.
    Also I use opus 150 psu, and you use 120 opus. you need to find out how much power all your devices add up to in total watts. If its more than 120, it not going to work. opus 120 psu rails are as follows 12v- 3.5amps, 5v- 8amps
    and 3.3v- 8amps. 12v= 42watts, 5v= 40watts, and 3.3v= 26.4 total of 108watts useful watts.

    the price! the 3.5 westerndigital 7,200rpm 200gb sata dive cost between $90-$115 new. where is the 2.5 mobile drive cost aroung $230+ for a 4200rpm-5400rpm drive. If you have the space, I would go with 3.5 drive. you buy yo for the price of one, and double the space.

    why not put a cheap, small 7200rpm 2.5" drive internal for fast booting and operation, and then put an external USB drive for all your storage?
