Thats another think I was thinking about a while ago, SSD RAIDs... should have included that in the topic.
Now Ill admit, I know I dont need the speed, I'm more curious on the current possibilities.
I built a $5k desktop last summer, and intentionally left one PCIe3 port open and the intent was to be able to upgrade from my 500GB Samsung 840 Pro to a PCIe based SSD when they became realistic (in price). Ill probably never make that jump, since the SSD that I have is a beast in itself. But its just nice to know where/ how the world of SSD is changing things.
So would it make sense to upgrade to four 128GB Samsung 840 Pro drives in RAID, or get a 500GB PCIe based SSD (if lets say I had the need for faster speeds)? And will this always be the case until there is a faster standard to transfer data through than PCIe3 and SATA3, or could new technologies such the video TrevJonez posted make one of those methods preferable in the future?
