    I'm just wondering how hot your guys system harddrives are running.

    Good to hear, what is "normal" under these circumstances? My samsung drive is running at 26 celsius.

    You might want to take a look at this:

    See figure 4 on page 6. 39C almost optimal.

    320 GB Seagate 7200.10 (stock drive from Apple): 39C
    3 x 750 GB Samsung Spinpoint F1s: 28-32C

    System config: 8-core 2.8 GHz, 8800GT, 320 GB Seagate 7200.10, 750 x 3 Samsung Spinpoint F1, 10 GB RAM (2 GB Apple + 4x2 GB OWC)

    I'm not at home right now, so I can't give all the details, but these are the temps I almost always get when the system is idle or under light to moderate work. They may rise a bit when I push the Mac to the max. The interesting part is the difference between the (noisy, slow) stock drive that Apple thought would be perfect in this Mac, and the (faster, quieter) Sammys I've installed by myself. The Sammys make a lot of resonance, but other than that, they're great. They are always some 6-12C cooler than the stock drive. This is consistent, no matter which drive trays I use. I have OS X installed on both the 320 GB stock drive and one of the 750 GB Sammys, and I've been testing the temps when running the system from both.

    Perfectly normal every Seagate I have owned has always run at least 5-10C higher than most other makes of drive. It has been this way for years but Seagate has always had the best warranty coverage so if they die you have a better chance of it still being under it than most other makes.

    Cooler may be worse according to the Google report. Their
    stats show average failure rates increasing significantly as
    the temperatures drop below 40C. At 20C the AFR is approx
    4 times the AFR at 40C.

    Careful with the stats though ;)
