Fujifilm LTO Ultrium 7 - Data Cartridge
Introducing Fujifilm LTO Ultrium 7 :
- In native mode, with a capacity of 6 TB and a transfer rate of 300 MB/sec.
- In compressed mode, with a capacity of 15 TB and a transfer rate of 750 MB/sec, with, for the first time on the LTO format, a compression ratio of 2.5:1 to meet users' growing needs in terms of data volumes to be archived.
Data compression is carried out by a chip inside the reader, so the rate achieved depends on the performance of this same chip.
Similarly, the server must be able to handle a higher data flow speed than that generated by the LTO tape drive. If this is not the case, a kind of containment or overflow is created, which slows down data transfer and can result in a "shoeshine" phenomenon: the tape drive stops to limit the data flow and then starts up again, which is not good for the internal mechanics of the drives.
As for files, some, like bitmap images, simply can't be compressed.
The Fujifilm LTO Ultrium 7 generation of recorders is of course write-compatible with LTO-7 tapes, and read-compatible with LTO-5 tapes. As with the previous generation, LTO Ultrium 7 hardware incorporates advanced encryption technology (AES) and LTFS double-partitioning. This tape is compatible only with LTO-7 drives/recorders.
