My first SSD purchase(s), were a batch of five, OCZ Agility 30GB SSDs. I figured that I would run two in RAID-0, on each of my two main desktops, and have a spare, maybe for a friend.
Well, after running a pair in RAID-0, and getting good initial benchmarks right after installation, the lack of TRIM, and the smaller SSD size, meant that my benchmarks after a week or so, were WORSE than a single drive, that had been receiving TRIM commands. So I reluctantly broke them up, and was using them individually as boot / OS drives, for a pair of Core2Quad Win7 64-bit desktop PCs. Which, they worked out fairly well for a couple of years, until the updates started piling one, but at some point, there just wasn't enough free space left to effectively use the PC without slowdown and pauses.
I had also given one of the (new) 30GB Agility SSDs to a buddy of mine, with an Athlon II X4 rig that I had hooked him up with. (Windows 7 Home retail upgrade, 30GB SSD, and Athlon II X4 AM3 CPU were his collective Christmas present that year. He's still using the X4 and Win7, but we upgraded his SSD finally to a decent M500 120GB SSD some years later, when he was "feeling the pinch" of lack of storage as well.)
I kind of forgot what I upgraded to in the interim, but I think that it was a pair of 80GB Intel X25-M G2 drives, which were all the rage back then. Pretty solid drives, overall, and endurance built like tanks.
