On SSDs DRAM cache is also used for storing the logical-to-physical
sector mapping of the flash translation layer; accessing it on flash is
apparently too slow.
There is a lot of complicated firmware in SSDs to make them look as much
like a traditional hard drive as possible, so that traditional hard drive
filesystems can be used unchanged. This firmware has been known to have
bugs in it.
Whereas the Linux kernel includes a few filesystems purpose-designed for
operation on raw flash devices, that integrate wear-levelling etc right
into the block allocation algorithms. Wouldn’t it be much better (more
efficient and more reliable) to get rid of most of that firmware layer,
and use these sorts of filesystems directly?
