So having posted in the wrong thread about this, I thought it best to start a new one. I'm looking to upgrade my mac pro to SSD, its a early 2008 model, and is now painfully slow, I'm assuming to the fact the drives are all aging, but I'd like to get a couple more years out of it. So having noticed the massive improvement in upgrading my macbook pro with an SSD, I'm looking to do the same to the Mac Pro. Samsung EVO 850 & OWC Accelsior S is the hardware combination I'm looking at, with the intention of using the SSD as the boot drive. I do want to check however 1. It will be able to boot from this 2. The PCI-e slots in the mac pro are 100% compatible with this card. I did have a response in the wrong thread, but before I blow £300 on all this, I want to check I'm 100% getting the right thing..... Any help appreciated.
