I have been running Intel X25-V 40GB drives on my crunching rigs since their launch with no issues.

To maximise longevity I have implemented the following:

1: Only used 30Gb for the partitions to greatly increase spare area.

2: Made sure they are all correctly write block aligned.

3: Disabled the page file.

4: Increased Boinc write to disk to 600 from default.

I am using XP x64 so no TRIM available but the drives are fine without it for this usage profile.

I made a huge thread ages ago about the Jmicron drives and have to agree they were total garbage

I have seen reports and had returns of quite a few Ilindrix and Sandforce drives dying very quickly but have seen very few (one total if my memory is currently working ok ) of the same reports of Intel G2 drives falling over so if I was buying again I would still go for the little Intels...
