So I have a 2012 iMac. I got the base model 21.5" which means I have a painfully slow 5400 RPM hard drive. The pure SSD option would have cost $1,300 ($1 more than the $1,299 base price) if I could even get it but you had to get the 27" to even have the option.
The iMac is very fast with the obvious bottleneck being the 5400 RPM HDD. I want really a better than stock setup with insane speed. Considering that anything under $1,300 is actually a savings (lol) and with the possibility of even being superior in speed to the internal SSD. The issue I'm most concerned with now in my choice is if it will be bootable. This is especially true with the RAID options because as the ones in my price range are SOFTWARE RAID I wonder how it could be possible to be bootable?
I've narrowed down my choices to these four options, in no particular order:
Pegasus J4 4 drive thunderbolt 2.5" storage chassis, RAID configurable I'll probably get 4 x 64 GB SSDs and configure them in RAID 0 or maybe RAID 10
Any advice would be excellent. Feel free to make an alternative suggestion if you prefer. I'm ready to go as soon as I can make a choice.
Again my machine is:
Apple iMac 21.5", Late 2012 / i5 2.7 GHz / 8 GB RAM / 1 TB HDD / GeForce GT 640M 512MB DDR5 / OS X 10.8
