Hi there, i have 2 pieces of WD Blue 500GB 5400RPM drive lying around, is it a good idea to RAID 0 them together? What are the good/bad impacts on it? Currently, what i understand is: 1. Battery life will be much shorter. 2. Double the transfer rate 3. Ever so slightly heavier? Lol.. 4. Failure rate is doubled (doesn't really matter) Question: 1. How does it compare to SSD? 2. How much shorter will the battery be? 3. Will it boost up performance significantly? 4. Can i still boot camp on RAID? If no, not a big deal, im sure parallel still works lol. 4. How fast are 2 x 7200RPM drives in RAID compared to 2 x 5400RPM in RAID and then compared to a single low-mid end SSD, and no, im not getting a SSD for this MBP, just asking Specs are: MBP 2009 - C2D 2.26GHz - 8GB 1066MHz RAM (I find that 1333 has lots of issues on this model) - Currently 250GB HDD Planning to: Remove the optical drive and install a optical drive conversion kit and dump in 2 500GB WD Blue. Generally speaking, 2 x 5400RPM should already double the performance of the original 250GB right?
