Many thanks,

The product brief on the chip is here.

http://www.jmicron.com/PDF/brief/jms583.pdf

It doesn't waste a thing, in that it only
connects to two lanes of four on the M.2 .

I presume this is a bandwidth balance, so a Samsung
that runs at 2.5GB/sec, well, the bridge USB3.1 Rev2
side can only do 1GB/sec anyway. So they cut the
lanes in half, to a theoretical ~2GB/sec. And at the
usual PCIe efficiency due to buffer size, that
gets them 1GB/sec.

The sheet mentions TRIM, so there must be some
kind of passthru in the OS driver.

The block diagram shows a "RISC" processor inside it.
Makes you wonder what IP they bought for that. Not
your usual 8085.

It looks like a sweet design.

Thank you!
