Hi everyone,
I am new to the forum, but have watched Linus' video for a long time. So the thing is that right now I am using a QNAP home NAS, and the read/write speed is way lower than I needed. So I want to build an 8 hard drives NAS with FreeNas, and thinking about either use RAID10 or RAID50. The NAS will have 4 ethernet ports connect to my switch with link aggregation, which will be 4GbE, and on the other end of the switch will be my main computer with 4 port link aggregation as well. (Linus proved this work in one of his videos) I am not really worry about other devices since I won't be coping large files on those devices anyway.....
Parts that I will be using:
Supermicro X11SSL-F
Intel Xeon E3-1230 V5
IMB ServerRaid M1015 crossflash to IT mode
16GB ECC Ram DDR4
I will be using 1TB hard drives, so RAID 10 will give me 4TB space while RAID 50 will give me 6TB of space. For me, 4TB is more than enough for backup my files as well as streaming movies.
So the question is
1. What read/write speed can I get from RAID 10 and RAID 50 (in a 8 hard drive NAS)? Can either of them take full advantage of the 4GbE ethernet connection I have?
2. Which RAID is safer just in case of a hard drive failure? I've heard RAID 50 is safer since any hard drive can fail, but if I loose two of the mirrored drives in RAID10, I will loose everything. But how slower RAID 50 will be?
Thank you all!
