Tape drive users have been busy since we surveyed readers about LTO-4 drives in December 2007. Adoption has increased 25 points, up to 35% in our most recent survey; and 42% say they have plans to deploy LTO-4 drives in the future. While LTO-4 usage has jumped from last year, LTO-3 is still the preferred drive of choice of those surveyed. Fifty-eight percent of respondents currently use LTO-3 drives vs. 63% last year. LTO-2 usage has increased a bit since last year, while LTO-1 has faded slightly. For those adopting LTO-4 drives, 43% say they're part of a new library, 41% are replacing older drives with LTO-4, and 16% are adding them to an existing library. LTO-4's native encryption hasn't found more takers since last year, with 34% saying they won't use that feature of the drive vs. 35% who didn't use it last year. Sixty-one percent of those surveyed are deploying LTO-4 for its 800GB capacity.
