I've had the same experience - but my point is: those aren't "spares". If you use them they aren't "spares".
The same also happened to people with raid arrays at that time. Suddenly the advice on the mdraid list was to mix and match manufacturers in an array to reduce the likelihood of simultaneous failure.
That has long been the advice for building RAID arrays. At least purchase drives from different suppliers [and hope they don't drop ship them from the same place]. But manufacturer defect isn't really the same as failure-due-to-usage as is being discussed here in relation to SSDs. A reasonable burn-in of all parts, including spares, is a good idea if you really don't want to end up in a corner. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
