Is your measurement in Celsius? And if it's Fahrenheit how is the SSD so cool? 32 Degrees fahrenheit is 0 celsius. . . freezing, no? So is the temperature measuring unit on the SSD faulty?</p> <p>Josh</p> I about flipped when I saw “171 degrees” for the CPU temperature. . my macbook rarely goes above 90.

Alex, the beta versions of Microsoft Windows Server 2008 (and now its public release version) are by far the most stable versions of any Microsoft operating system I’ve tested.

I tested Server 2008 and Vista betas side-by-side, noting that they share similar guts. The Server 2008 beta, minus all the Mac OS X-infringing, ram-hogging, eye candy ran without error. It never crashed under load, and it functioned soundly.

The test results impressed the hell out of me, especially since Microsoft released Vista to consumers in such an unstable state.

I say that your comparison falls short now that we have Windows Server 2008.

Software striping still interleaves access over the drives involved.</p> Alex - you are absolutely wrong that software RAID does not increase performance.

Warning: Don't ever EVER put anything you care about AT ALL on a RAID0 drive, even with 10.5's backup. ESPECIALLY in a laptop with software RAID like this. That's a minimum of 4x as likely to fail and lose it all as a single drive would be. Software RAID burns many CPU cycles trying to emulate hardware RAID, creating tons of extra heat. Heat is the enemy, and then it's still scattering bits of your files on each drive, killing much more data when one of the drives fails. RAID5 is the way to get extra speed for things you care about. RAID0 is almost like using a beta microsoft OS as far as I'm concerned. :-D IMHO</p> Also, while I’m here.

I just want to clue you in here that there's no hardware RAID on a MBPro, lol. Any "RAID" you have set up on a MBPro is not from the motherboard--it's software RAID...hence, no increase in speed. It only combines the size of the two drives into a single visible drive. If this is what you're referring to, I'm unsure where the idea came from that a laptop with one factory HDD bay would have hardware RAID on the motherboard (and also be one of the only laptops I've ever heard of with a hardware RAID). Typically, people that need RAID speed work on their desktop. Laptops are not meant to be the powerhouse, although a MBP is rather impressive in many aspects.

My battery is really old, and I can no longer tell whether the computer is running longer or not. But I just got a new battery, and will see what happens.

  1. Do you notice any increaed battery time?
  2. Would an SSD IDE/ATA and an SSD SATA drive in RAID 0 work? Perhaps? The drives will be different, I know this, but do you think that would be a problem?

Thanks for your time.
