Jul 22, 2016 · While RAID60 will give you the best space, RAID10 will give you the most secure option, rebuilds are not putting pressure on the remaining disks, recovery time of a failed disk is much lower, read and write speeds are faster (even though you say this isn’t an issue).

Mar 7, 2014 · Looking at the options when building a new array for holding and running our Virtual Machines. 8 x 900GB drives As far as I can see both would have a 50% overhead, the RAID 10 would give less penalty on the write but a small chance of failure should 2 mirrored drives fail (Compared to any 2 in the RAID 60) What would you recommend out of these two?

Aug 15, 2013 · I'm investigating some 4TB database systems and I'm comparing differences between RAID-10 & RAID-50. I know how to calculate the IOPS for common RAID levels like RAID-1, RAID-5 & RAID-10.

Based on excellent comments received I have attempted a RAID60 consisting of 5 spans of 8 disks each for the following reasons: Based on recent rebuild that included 2 spans of 20 disks, I estimate the rebuild time for the 8+2 configuration to be reasonable.

During a rebuild, a RAID60 will only cause high load on the sub-RAID6, that contains the disk, that failed and is being rebuild. However, even then, if you have one large uniform application on your RAID60 and you have no means to route load away from the sub- RAID6 , that is under rebuild, then your application will still be limited by those ...

Jun 9, 2017 · In a RAID60 if you lose one of the RAID6 spans (3 drives fail), then presumably you would lose the entire RAID60 volume. Is that correct? Does that mean it’s more reliable to just split the data into two RAID6 arrays if possible? You are correct. Each RAID 6 set is one “drive” in the RAID 0. Lose any and all is lost.

raidとは、複数の独立した物理ディスクによる1つのグループです。この文書では、raidの様々なレベル（raid 0、raid 1、raid 5、raid 10、raid 50、raid 60）について説明します。

raid是一组独立的物理磁盘。本文说明不同级别的raid（raid 0、raid 1、raid 5、raid 10、raid 50、raid 60）

Le niveau RAID 1 permet d’enregistrer les données simultanément sur deux disques physiques. En cas de panne d'un disque, le contenu de l'autre peut servir à faire fonctionner le système et à reconstruire le disque physique en panne.

Jul 22, 2014 · 1. I assume you meant 3.7TB disks. 2. Those disks take a LONG time to rebuild. Assume a disk fails and is replaced, a raid6 over the entire 24 disks will take significantly longer to rebuild than raid60, and the smaller the raid6 group in each 60 the better in that regard (so 8x3 raid 60 will take shortest time, but at that point you lose 2/3 your capacity)
