YOU are RIGHT, to not use benchmarks!!, Use reliability/Least user problems.
.. My choice is the Samsung 830, and the Curcial M4. Both can be had for around $115 on sale at newegg.
.. Performance wise on sata II you will see NO diff between the better Sata III SSDs.
.. When you move to SATA III, in real Life usage, very little difference.
.. The lower end, which uses Async NAND (ie Agility III, and IV, Muskin Low end) will be a
little lower in real life.
.. Vertex IV has not need out long enought to get a real feel for Reliability/user Problems.
I have:
2 x 128 Gig Curcial M4s (one on a Sata II Port- OS, and one just a storage drive), and a 256 Gig M4, OS drive. - Bought on sale at Newegg for $180.
2 x 128 Gig Samsung 830 (Both as a storage drive), and a 256 Gig Samsung 830, OS drive - Also Bought on sale at Newegg for $180.
2 x Agillity IIIs - Backup OS drive for Wife's system, Sata II port. 2nd one was a storge drive.

For about $60 More you can move up to a 256 Gig M4/830, But would require watching closely for sale on newegg.
