Raid 5 Stripe size

[tekgeek1205]

So im setting up raid 5 with 5 drives. All drives are 512 bytes per sector drives. Should I set my stripe size to = my sector size, or a multiple/factor of my sector size.

 

I'll be storing games and a lot of .mp4's. Some of the older games will be loaded directly from the array, the newer ones will only be "hot" backups. The .mp4's will be a plex library @ about 4TB total. File sizes 250MB to +5GB

stripe size depends on what type of files ur going to transfer

larger stripe sizes enable more I/O operations per second, and I/O performance increases even more if large stripe sizes are used.

just keep in mind having too large stripe sizes that tiny files will go slow

I have set up many RAID's for home and enterprise use. If its just general storage (like you said) stick to 128KB block sizes. Yeah you can gain from setting smaller block sizes if you are storing small files (a HDD must rewrite the whole block, so if you have 512KB blocks and are only storing 15KB files you are wasting a lot of time rewriting whole blocks).

 

I find 128KB to be a happy medium.

Thanks, i'll give 128KB a shot when my backup is complete.
