A lot of our customers use this to connect to a desktop SAS LTO drive or tape library. The Sonnet Echo Express SEL is a compact Thunderbolt enclosure that holds a PCIe card like the ATTO H680.
These PCIe cards can go in a Thunderbolt expansion like the Sonnet Echo Express SEL shown here. See this link for more details on the ATTO. H644 and H608 cards can also be used, but ensure they have the correct SAS connectors for your drive. To connect a SAS or FC LTO-5, 6, 7 or 8 drive to a Mac use the ATTO ExpressSAS H680, H1280 or ATTO Celerity FC PCIe cards from ATTO. Use SAS drives, they are cheaper, they use more durable cables, there is no configuration and SAS gives the same performance. LTO drives have either SAS or Fibre Channel interfaces. The LTFS standard requires an LTO-8, LTO-7, LTO-6 or LTO-5 tape drive. IBM make all LTO-7 and LTO-8 mechanisms, so we supply IBM Barium Ferrite tapes for perfect compatibility. Unlike other labels each tape can have a different code, you are not limited to a set sequence. So you can clearly label Main and Safety, or add a project ident. They have a standard barcode, plus you can add unique text labels on the left as shown opposite. We can supply LTO tapes in Europe at great prices with custom YoYotta ID labels printed on durable plastic. Unlike hard drives the tapes are designed with a 30 year shelf life.Īll tapes must have barcode labels, this identifies the tape and allows use in a library. Some space is reserved for LTFS tape indexes. LTO-5 tape stores up to 1.25 TB and can be read or written at 140MB/s. LTO-6 tape stores up to 2.3 TB and are a little faster at 160MB/s.
LTO-7 tape stores up to 5.6 TB and are a lot faster at 250-300MB/s. LTO-8 tape stores up to 11.3 TB and are a lot faster at 250-300MB/s.

LTO-9 tape stores up to 17.45 TB and are a lot faster at 250-300MB/s and 350-400MB/s for full height drives.
