- My experience, with hundreds of tapes on multiple 8500 drives on an Epoch,
- is that the video grade tapes cause many write errors; some of the errors
- are "soft", and have no apparent effect (and may not even be logged,
- depending on your driver), but *do* drastically reduce both throughput
- and tape capacity; other errors, the minority, are hard and will abort the
- writes. We have switched to exclusive use of Sony "QG" data grade tapes,
- with *no* errors recorded in months now. We have never had any trouble
- *reading* either quality tape.
-
- As for cost, our price for the Sony data grades, quantity 50, is now
- less than $12/tape. I don't consider that excessive for the
- reliability, consistent throughput and capacity.
