Reliability and compatibility - Intel
Highest performance/bragging rights Sata III Using the Sandforce 2xxx controller.
The High end will provide a noted increase in boot time and program load over the Mid tier SSDs, However the advantage inuse is not significantly higher than the mid-level - with some exceptions.
(1) The is a BIG boost in loading your operating system and loading program, also installs goes faster.
(2) In program performance, not a big boost.
a word of caution on the new SATA III Sandforce controllers - If they work they are great, but there is some problems with the firmware. Corsair is doing a voluntary recall on one of theirs (Both firmware and a hardware problem). OCZ is downplaying the problem. If you look at the Newegg reviews (always take with a grain of salt) the percentage of look scores is much higher than it should be. It is across the board and not limited to a specific brand. Most problems appear to be with the newer MB chipsets (ie SB), and laptops are a real toss up as to even getting the operating system to load.
Hate to say it but I'd go Intel for the newer SATA III SSDs.
