Doesn't have the flexiblity or scalability, but I/O ain't an issue.
A poor NAS or SAN can be far far slower or if not done right be more prone to failure
Some cheaper NAS gear have piss poor performance.
NUUO does actually support external DAS/SAN appliances from reputable storage companies.
How is lacking I/O going to kill drives anyway ?
My money would be more that it is running an onboard software RAID implementation, RAID 5 and with consumer drives. Potentially, depends what the OP is actually using.
Some combination there might be causing dramas. I know that consumer drives can timeout on an error recovery/sector remap and drop off the array and make it degraded. Also many storage companies have recommended not using RAID 5 in general.
Plus environmental concerns aren't necessarily ruled out.
Heat, vibration or power. Would be an absolute pain to determine though. Any voltage, temperature and fan logging for a start ?
If it's in a server room that's great but if a case fan is seized or it's choked with dust it can still overheat for example.
Also some good data would be helpful, how many are actually failing as a fraction of how many were installed, how long are they lasting, how are they actually failing ?
Does sound rather short but is it a bad batch or just some small statistical anomaly or is there a much worse underlying issue.
