Hi all!
I'm getting to experience using a MegaRAID SAS 9260-4i 6Gbps controller card with 4x4TB (HGST MegaScale DC 4000.B HMS5C4040BLE640 3yr warranty) drives (total with raid card+cable $315) on because I thought having a isolated even migrate-able controller would ensure the ideal storage function. I also bought a 8TB Seagate Backup Plus USB drive with 2yr warranty (total $150.85) .
RAID 5:
10.9TB RAID 5 from 16TB drive (4 drives 284.66 shipped)
2TB write transfer sustained 20+MB/s
170MB/s + read
RAID 10:
7.27TB available
12GB write sustained 32-36MB/s (bursted 600MB/s)
260MB/s + read
Seagate 8TB USB:
7.27TB available
2TB write transfer sustained 140-160MB/s
150-200MB/s read sustained (bursted 1.2Gbps down)
I don't have one with a battery so cache is likely not enabled and I don't have to worry about volume loss but that slow write compared RAID10 vs USB solution. I'm going to use the Z390 motherboard's RAID 10 and determine if there is a gain. I got a deal I thought on the 4TB drives and considering their cost full price it was thought they should perform better than the USB.
Can anyone readily say any advantages of the internal HDDS vs current USB tech? what disadvantages are there (besides 1 year less warranty)?
