Product reliability
Enterprise. In the reliability category, Quantum came in second on two statements and was tied on another, but it still managed to roll up the highest mark (6.46). That slight chink in Quantum’s armor wasn’t enough for IBM (6.33) or Oracle (6.29) to prevail.

Breaking down the numbers
- Quantum “stumbled,” if you can call it that, on non-disruptive updates/patches (6.13 to IBM’s 6.24) and providing upgrade guidance (6.36 to Oracle’s 6.43).
- IBM tied Quantum’s 6.41 on the statement “This product experiences very few bugs.”
- Users’ tape library expectations are apparently being met, with an overall 6.50 average for “The product meets my service-level requirement.”
Midrange. The product reliability category is typically something of an Achilles’ heel for midrange tape libraries, with scores dipping compared to the other categories. That’s true again for the overall average (6.15), but not for Quantum, which mustered an excellent 6.80 -- the highest winning score we’ve ever seen for midrange product reliability. IBM finished second with a score (6.46) that would have been a winner in three of the previous five tape library surveys. Dell (6.30) broke into the top three by just barely edging out Oracle (6.26).

Breaking down the numbers
- Quantum was buoyed by a 7.18 on the statement “This product requires very few unplanned patches/updates.”
- Quantum won all but one of the seven statements, coming in fourth to IBM’s 6.24 for “Patches/updates can be applied non-disruptively.”
- With the exception of IBM, most vendors were tripped up by the patches/updates statement, with most getting their lowest scores on that statement.
