Tape Drive Query

Greetings..!!

I am using tape drive with tape of 3TB of LTO-5.  I want to use the compression mode 2:1.

Then will anybody tell me, what is the maximum size of data I'll store in 3TB tape after compression.

 

Thanks & Regards,

Shashank Saxena

Re: Tape Drive Query

LTO-5 has a native capacity of 1.5TB and a *theoretical* capacity of 3TB assuming a 2:1 compression.

The compression ratio depends on the type of data, you cannot compress a already compressed file, e.g. jpg, mpg, etc ...

So you should calculate with 1.5TB capacity ...


Hope this helps!

Torsten.
