i just did the same thing except.. one of my samsungs is a msata 512gb, and the other is a samsung pro 840 512 gb. i have those in raid and then a western digital 700gb drive. the performance is insane!!
My 32gb msata done the same I can only see it if I go into ahci mode. when in raid 0 with my 500gb 7200 rpm drive I can't see it.so if you still have your msata caching another drive that could be a reason you can't see it.Don't know if this will help you its the first time I've dealt with caching drives. So when I put in my 512ssd I left it caching my storage drive as their was only a second or two difference in boot up speedNow I have a question. It came with a 64gb msata drive too. When I take it out I loose the
Config screen that comes up before the boot screen. Is this going to be a problem if I want to
Switch it out for a larger msata chip? It shows up on "my computer" now and it didn't
Before I swapped the ssds in. Anyone know if this is going to be a problem?
