Probably not so important in this case, but consider write wear on the SSD, too: they don't last quite so long under intensive write loads. I sincerely doubt a tape drive can keep up with despooling off a 10Gb/s SAS drive, or even a 6Gb/s SATA one. (Should be a fair assessment as those numbers are as realistic as LTO-6's 400MB/s.)
