I bought a couple of these Kingston 60GB SSDs (previous generation of these drives) as my system drive (for OS and configuration data) two years ago and I have exactly watched how they performed, how they behaved, how they dealt with TRIM and everything else. They have held up perfectly, there can be no question of performance losses. They're used on two always-on servers and mirrored to a slow-spinning hard drive, but with a large pending write queue, so write speeds aren't too bad if you're not writing much during. Like updating 30 software packages or something. Reading is only done on SSDs, so you rarely notice there's also an HDD in the mix. Based on that I bought them for another system but as mirrors for each other. So far they're fast, bullet-like, and good value for money. Not necessarily the first product that comes to mind for a server, but they've held up like soldiers and are exactly what you need.
