With my cache drive capped at 18Gb I haven’t had any problems yet. I wish sandisk would fix this so I didn’t have to cap the drive. Honestly, it’s beginning to seem like a design flaw and they should have made it a 64Gb drive that is overprovisioned to 32Gb.
This is exactly what my OCZ synapse drive I used to use did. Honestly, Sandisk should just release a new drive and give us all discounts on a new one if we send the old one in.
