Maybe. Not much, if any, though. RAPID takes some of your RAM for write caching, not merely read caching. As a former accidental DBA, I believe I have become sufficiently jaded with storage technology to consider such techniques, beyond the conservative efforts of most OSes, to be playing with fire.
So we were both "accidental DBAs." But again -- that's my point in my previous post.
Excluding Magician, the other two softwares I mentioned offer server versions. But you're also correct: What sort of hardware, components and software are you going to pick for running the San Onofre nuclear power-plant? What are you going to choose for hospital ER systems? There was a time when Intel was actually sued for a glitch in a processor which caused cumulative errors in the Operations Research model used in constructing a large building.
For workstations -- end-users -- like I said, you can pick your poison. If you think it helps, the issue then focuses on the stability and reliability of the software, and I gave my pontifications. If you don't think it helps, buy a couple MX100's, validate whether TRIM is operational in a RAID0 array, and be my guest. Two (or three or four . . ) are going to cost a lot more than a single 840/850/Pro/EVO with the software, or an MX100 and a license to Primo-/Super-cache.
Just as a footnote, and people have heard enough of it. The laptop options weren't too great when I retired, and as I retired -- I did not travel much or need a laptop. I deferred my "wireless experience" for a long time, even though I'd installed the wireless component of a LAN in an small office and done some other tweaks.
So I finally acquired a C2D-era "executive" laptop -- maybe six years old!! I got out my PHillips screwdriver immediately. Replaced the mini-PCIe NIC with a wireless N, replaced the WD Blue HDD with an MX100. So? Nothing too stunning at that point.
Then, I replaced the 2x1GB SO-DIMM RAMs with a bargain pair of 2x4GB. What can you really use 8GB of RAM for on a C2D laptop with "bidnis applications?"
We-ull, Pil-grim! Lemme tell ya! That old laptop had an SATA-II controller, so the SATA-III SSD was bottlenecked to <= 300 MB/s sequential read-rate.
DO you WANT TO KNOW WHAT IT IS NOW?!!
1,200+ MB/s. And -- AND! -- the 4K random read rate -- a slug-rating for HDDs in 2 digits and still only 50+ MB/s for an SSD [edit: ] on an SATA-II interface-- it's 250 MB/s!!
And THAT's the way you turn an old slug of a laptop into a "snappy" performer. the 4K read-rate tells all.
