Let me first say that I do not have a full FlexRAID implementation; I have been playing with the trial version on my media-PC. So far I have not found anything I don't like and will do the full implementation the next time I can catch a 3TB Seagate Barracuda on sale for $110.
For video storage and serving, I find FlexRAID to have a number of pluses over hardware RAID. With FlexRAID:
- You can add drives of any size to the array -- the only requirement is that the parity drive must be as large as the largest drive in the array
- You can add drives incrementally as needed without having to destructively rebuild the array
- Drives are NTFS formatted and files are stored on single drives -- the whole array does not have to spin up to play a movie
- Any drive can be accessed independently of the array by drive letter -- you can decide where to put a file or let the array decide; you can detach a USB drive from the array and attach it to another device for file exchange
- You can have multiple parity disks if the array gets large
- If desired, you can segregate your drives into multiple arrays -- i.e two 5 disk arrays with 1 parity drive each instead of one 10 disk array with 2 parity drives
- The parity drive gets updated on demand or via nightly schedule -- the lack of continuous updating makes it fast
FlexRAID is extremely flexible. I feel these features are major pluses for a content storage system where nightly or on-demand updating of the parity disk is more than adequate. I would not use FlexRAID for high traffic business class data that demands continuous protection. For that I would choose hardware RAID 1 or 5 and I would choose it at the enclosure level -- either NAS RAID or eSATA RAID enclosures like the Mediasonic HUR1-SU3S2 or HFR2-SU3S2 -- rather than a RAID card and dumb enclosure.Edited by Kelson - 7/17/13 at 7:26am
