RAID 10 vs. RAID 6 + Read/Write Intensive (QB on Dell Server)

seguse · ‎January 03, 2020

Is QuickBooks more of a “read intensive” or “write intensive” application?
Is QuickBooks more of a “sequential read/write” or “random read/write” application?
What type of RAID is recommended on a server running SSDs? RAID 6 or RAID 10?

After tons of research it seems like a 50/50 split on the application being both read/write. As far as the RAID you could go either way especially with SSDs. I did some benchmark testing between RAID 6 and RAID 10 and my findings were 50% less IOPS on Sequential Read/Writes and 50% less IOPS on Random Read when using RAID 6. If you're using high performance SSDs than either RAID would work fine. The RAID 10 IOPS were around 6,500-8500 on Read/Write.

I prefer to use RAID 1, easier to recover from IMO and configure
