And when that happens you’ll have to stop work until you get your backup loaded on a new array. ![]() “Therefore, in my experience – which includes working in large storage companies, so I have a large sample – a small array is as likely to have a power supply failure as a disk failure. However, low-cost arrays like the ThunderBay only have one power supply and, in my experience, a higher failure rate than any one drive, or even any four drives. This means that if you use RAID 0 you have less than a 1 in 5 chance of a drive failure in any given year with a 4 drive array. Based on the best available research evidence, all hard drives have an MTBF of ≈300,000 hours or an annual failure rate of 3-4%. “On the issue of RAID 0 vs RAID 5 on low-cost arrays: I prefer RAID 0. Recently, after posting a review of a new RAID from OWC, Robin Harris ( wrote a very intriguing comment: Storage is an essential element of media editing – both audio and video – and I enjoy testing and reviewing the latest storage hardware as it comes out. A RAID ( Redundant Array of Independent Disks) collects a group of hard disks into a single enclosure to provide great speed, storage capacity, and/or security than is available with a single hard drive alone. ![]()
