Please explain the logic of the SSD L2 cache.
Does the recorded data always pass through SSD L2 write cache or is it ignored in some cases? Does recorded data always become available through the SSD L2 read cache?

Re: L2 SSD cache
Here's the official page on what an L2 does.
Basically, it's inbetween a L1 RAM cache (fastest), and the speed of your regular hard drive (slowest). If it's a read/write L2 cache (which I think most people end up using), it 1) Keeps things the computer requests from the hard drive on the SSD, for faster reading access, and 2) Things written to the hard drive get put on the L2 before being written out to the hard drive. If they are accessed frequently enough, they end up staying on the L2 for an extended period of time.
I have one computer with a 60GB L2, and the boot drive doesn't even have that much data on it. That means that with enough time, the entire hard drive would be cached by the L2, for both reads and writes.
If you have enough RAM to make a L1 cache, using it along with a L2 (in the same Cache Task) gives you the best of both.
