The older Patriot SSD's, the Warp series have become relatively inexpensive (compared to other SSD's). Specifically the 32GB flavor can be purchased for around $85 a piece so I am considering purchasing 3 or 4 of them and striping them together using software RAID in my 2009 Mac Pro. Storage capacity and drive failure risk aside, are there any other negative connotations with running my OS and applications off of this RAID array? Assuming I will be using the drive bays and one of the optical slots, will the speed cap out after a certain number of drives (2,3,4)? My goal is to also put a traditional 1TB drive in one of the bays so that I am not just stuck with 128GB of space. Will the boot time, data accessability times, overall performance be driven down by the traditional HDD? Crazy to think of paying $400 for 128GB of hard drive space, but I am very intrigued to see how fast this bad boy would run under that outlined set up.
