One the other hand I have chronically had problems with tapes I couldn't read, had spots of data corruption, or that took 18 hours to restore a 1500 byte file.
Part of it is that the use of tapes is less routine so it is a common mistake to think you wrote a good tape but you didn't check it and it's unreadable.
Another competitor for LTO tapes is BD-XL, which is more expensive per unit TB but the drives are cheaper.
BD-XL is wildly more expensive than LTO, although that won't matter if you can't get LTO to be reliable for you. Just checking now, B & H Photo which tends to have good prices and a good supply chain, $54.57 for 10 100GB BD-XL or a terabyte (https://www.bhphotovideo.com/c/product/1101544-REG/verbatim_...), not so cutting edge and still with competition LTO-6 from Fujifilm, quantity 20, $11/TB (https://www.bhphotovideo.com/c/product/1096090-REG/fujifilm_...). We also have a problem with no one worth trusting making cheapest single level BDR discs, the least worst is CMC, and I wonder how long before BD-XL sufferer the same problem.
