Mmm.. Agility-2 has the first-gen Sandforce controller chip in it. Unfortunately, that chip/firmware has a bug which results in sudden-death syndrome from time to time. I have two (identical) beta drives here with that chip which have suffered from that problem.

All SSD makers who used that chip have had the same issue. OCZ takes the rap for it because they're the largest of the vendors.

I don't know if a later firmware update finally cured it or not, but I do have the low-level tools/knowledge to revive the bricked OCZ variants.

The -3 drives used a later, better Sandforce chip, and earlier models (no hyphen-value) used Indilinx controllers. The -4 series have gone back to Indilinx, which is now owned by OCZ.

Cheers
