Anyone know what exact tape they are talking about? When I google 15TB tape I only find a LTO-7 which is 6TB native, and 15TB compressed. Assuming a compression a compression ratio of 2.5 to 1 seems pretty crazy to me.
- userbinator 8y agoThey're probably referring to the TS1155 variant of https://en.wikipedia.org/wiki/IBM_3592 https://en.wikipedia.org/wiki/IBM_3592 . To be honest I never really understood the main reason for adding compression, especially since you can compress individual files far better using existing algorithms and then write those to tape. It must be a marketing thing.
- sliken 8y agoAh, thanks, they do list a 15TB tape. I looked around and could find the 10TB variety for $212 or so, but couldn't track down an actual 15TB tape for sale. The 10TB tape I found was "IBM 3592 JD Advanced Data Tape Cartridge 10TB/30TB (2727263)"
- slavak 8y agoThe cartridge is the same. It can be reformatted from 10 to 15TB using the newer tape drive. https://spectralogic.com/features/ts1155-technology-tape-drives/ https://spectralogic.com/features/ts1155-technology-tape-dri...
