![]() This way even if you had a power cut as data was being written, any data committed to the RAID controllers cache would be preserved by the battery to be written to the drives when power is restored. ![]() If you really depend on your data I would recommend a hardware RAID controller with battery backed cache. In your situation the rebuild time shouldn't be too bad, but software RAID controllers aren't great. software RAID has not been a possibility for shared storage resources in. RAID 6 and 60 are also hampered by these issues but can tolerate another drive dropping during the stressful rebuild so the problem isn't quite so bad. steadily growing in recent years as a cost-effective alternative to SCSI. RAID 5 is slower than RAID 1 or 10 for rebuilds due to the parity calculations. However, RAID as a software solution does not make. The typical method to defeat this is to employ RAID 1/10/6/60. Windows, Linux, and macOS offer a wide range of alternatives for creating software RAID data storage. It's better to think of probablity of URE's rising with the overall RAID volume size rather than number of drives which is why this issue is being considered more and more with todays large drive sizes. SoftRAID is a Mac utility designed to increase the level of computer. During rebuilds the drives can be quite stressed and rebuilds may fail if another drive has any URE's (unrecoverable read errors). HDD Health for Mac OS X, download best alternative solutions carefully chosen by. The general consensus is that RAID5 rebulid times are getting quite high for large RAID 5 volumes.
