apart from the fact that they seem to be hard to source, this is a big question about this interesting device for me too. I hope so, since it should be simpler to get right (and test) than all the complexity of a block-remapping flash device with (effectively) an internal filesystem. Really, this all comes down to the fact that there's still apparently not a good answer to the very frequently asked question of "what's a good slog device?" Of course, "good" varies by circumstance[*], but having a range of solutions means more chance of fitting a range of circumstances. There are several circumstances currently lacking a good solution, it seems. -- Dan. [*] I have slog and l2arc on partitions of generic 5400rpm sata disks, together with rpool, to great effect -- because in that case the raidz data pool is 4 disks behind a single usb port.
