    not quite MAX 3147 is £170 now.
    64GB SSD around £900.

    However, for those who use SCSI, to answer the question, the ATTO SCSI Cards are the only SCSI option for the G5's.

    There are a number of 10K and 15K SCSI drives available - Cheetah 10K.7 - 147GB ULTRA 320 SCSI drive, in tests in a G5, performed better than a Cheeta 15K.
    its not meaningful to say things like 'performed better' without a lot more information-
    as performance varies between drives with different codecs and compression. some drives are better at somethings, some are better at others.

    none of the cheetah drives i tested ever worked great.
    there is a great deal of difference between different drives and drive manufacturers.

    simon- you were raiding drives up a few months ago on mac pro's-

    did you unraid them?

    or are you still doing this?

    There is nothing wrong with having more than one 64Gb SSD disks in your Mac Pro or G5. Obviously the G5 will only take one additional but you can always remove the CD ROM. In the Mac Pro however, you can put three SSD disks in addition to your system disk if you wanted to.

    Then point to folders on each of the disk to get a larger capacity than 64Gb.

    Richard,
    In response to your comments -

    I use
    Mac Pros - 2x 500G SATA raided (WD5000YS)
    G5 - single SCSI (not raided) (Cheetah 10K.7 147GB ULTRA 320)

    These configuration seem to work fine for the majority of the work encountered

    re 'performs better' comment
    this was based on Hughs testing results between various SCSI drives both 10K & 15K.
    I agree - there are a lot of factors to be considered - of what was available in the price range and size, the recommendation after tests was the drive quoted.

    Nevs Fujitsu MAX3147NP was not compared

    It was not a comparrison between SSD and SATA

    ssd is sata - you have only 2 sata ports in g5 unless you buy an external sata card

    internal raiding of drives does not work better than single drive - and can work worse - as you know. internal raids not recommended - they do not improve performance.
    there is a also a great deal of difference between the individual performance of single sata drives- they do not all work the same.

    cheetah 10k7 scsi never recommended as scsi drive.


    there are indeed many things to consider - the most important being - the type of content you are using, and what codec.
    the performance of systems varies hugely depending on this.

    Richard is right. To be more clear. If you remove the CD rom drive you will have to use the IDE SSD in a G5.

    Richard,

    What scsi drive do you recommend?

    Hey Dan,

    This is the best overall answer to your question.

    Don't use a SCSI drive.

    There are close to a dozen threads on this board referring to SSD disks, specifically the Mtron SSD disk.

    Six months ago they were expensive and a 32Gb was about $3k US.
    Last month they went down and a 64Gb was about $2k US.
    This month a 128Gb is about $3k and the price is still dropping.

    Don't use a SCSI. The SSD (Solid State Disk) is a device that has a SATA interface but is made of the same memory used in RAM. This means it is much faster.

    The price of a SCSI card and SCSI disk is comparable to an SSD.
    However, a SCSI can only run 1/3 as well in performance. With the SSD you can run 14 layers with no loss using the DV codec or 7 layers of HD using the Apple Intermediate Codec.

    If you're in the US, there's a company called dvnation (about an hour away from me in San Antonio in fact) which is very easy to deal with. The guy who runs is is cool and I speak with him on the phone all the time. He's small but always has tons of disks in stock.
