I'm in the process of ordering a new Mac Pro 3.3 6 core, and was advised by a G-Tech to make sure to get the SSD from Apple vs aftermarket due to the fact Apple has it's own SSD firmware revision that will effectively run the Mac Pro more efficient. Based on the information that I've found within this site, Apple tends to throttle back it's drive controller operations to reduce fan speeds. Obviously going with an aftermarket drive would end up being around a $400.00 savings as it's well known about Apple and it's up-charge towards memory and disk drives. I would greatly appreciate some feedback if it's fact or fiction. Thank You.
