Sequential read speed is attainable while still having a (small) number of independent sequential cursors. The underlying SSD translation layer will be mapping to multiple banks/erase blocks anyway, and those are tens of megabytes each at most (even assuming a 'perfect' sequential mapping, which is virtually nonexistent). So you could be reading 5 files sequentially, each only producing blocks at 3GB/s. A not totally implausible access pattern for e.g. a LSM database, or object store.
