One day I found a really cheap LTO-4 drive that costed $150. Interesting, but I found it was not practical despite the price and decided against it. First, an 800 GB LTO-4 tape is no longer high density by today's standard, it couldn't even hold a 1 TB HDD image, also, I still had to pay for the necessary SAS peripherals to get it working, finally, the mechanical assembly inside a 10-year-old tape drive was not something that inspires confidence for data backup... Last time I've looked up, the cheapest decommissioned LTO-5 drive still costs $1000.
