Raid redundancy vs performance
Did you know?
RAID 5 is somewhat similar to RAID 6, except, it provides only one redundant (parity) drive, rather than two. The benefit of this is that you lose less raw capacity with RAID 5 than you do with RAID 6, the main disadvantage, of course, is that you have less redundancy and resiliency. As such, RAID 5 requires a minimum … See more When configuring a new storage setup, system administrators around the globe face the same dilemma: which RAID level to choose. Like with most things in life, it’s a compromise, a trade-off if you will. We need to balance … See more RAID 6 allows you to have two disks concurrently failwithin the array and it will remain active. Whilst other RAID levels may allow you to lose “up to two disks”, with RAID 6 you can lose an actual “two disks” and still be fine. … See more In this post, we’ve covered the fact that if you value redundancy over performance and raw capacity, you should probably be using RAID 5 or even better, RAID 6. This is a fairly broad statement, so we’ve covered the different … See more WebMar 29, 2024 · RAID (Redundant Arrays of Independent Disks) RAID is a technique that makes use of a combination of multiple disks instead of using a single disk for increased performance, data redundancy, or both. The term was coined by David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987.
