Even fastest compression algorithms like LZ4 need Core i5-4300U @1.9GHz in order to get 385MB/s [1]. You'd need a pretty powerful setup to have it keep up with SSD speed and you also need to be mindful of heat generated. Also, it would be pretty useless if the volume's encrypted.
Looking at these numbers you linked to (which seem to be in megabytes, it seems to me that decompression speeds could keep up. And I know write speeds on SSDs are a lot slower than the spec'd numbers, so the compression write speeds look plausible to me too.
The general idea is that modern CPUs tend to be instruction starved and sit idle because they are waiting on the slow memory buses that connect everything.
Am I missing something?
Now we're living with SSDs that can do 2GB/s and no CPU can decompress that quickly.
I'd totally buy a machine with a state-of-the-art CPU paired with one or two FPGAs that can be programmed as accelerators for crypto, compression, etc.
