REALLY wondering why 3 SSD's are the sweet spot on these systems. My experience has been either two or four drives for Raid 0. Guess the SSD's are a bit different?
There is no such thing as a "sweet spot", more drives=more throughput. Add drives until you saturate the bus and call it good.
Also, are you using an actual raid card, or the onboard motherboard raid?
How well does this work?
Do the onboard controllers have really fast processors, and, lots of cache?
Onboard controllers use the CPU and RAM, so "fast processors" and "lots of cache" are understatements.
With these machines capable of using so much ram, what ram disk setups do you use?
With SSDs in large arrays saturating the entire bus, you don't bother with complex setups. Just create a big array and hit it hard.
Also, why not a multiple drive, removable storage system?
Depends on the job at hand, I suppose, but I've never had a need for such a thing.
