Yeah, I wouldn't go for MLC, given it has a tenth the lifespan of SLC.

For the mentioned device, they claim a sequential read speed of 100MB/s,
sequential write speed of 80MB/s, random read speed of 80MB/s and random
write speed of 30MB/s. This is *much* better than figures quoted for many
other devices, but of course unless they publish the block size they used
for the random speed tests, the figures are completely useless.
