All,

What performance benefits does a 1GB RAID Card have over a 512MB RAID card. I am looking to put one in enterprise level server R720 and use it as a temporary file-server. Will I notice a difference copying large files 12GB-30GB in size? I will be using (5) 10k 1.2TB SAS drives. I am not sure of which RAID level I should use either..... RAID 5 perhaps?

Regards,

Original

i have seen a comparison of perc 5/i 256mb vs 512mb somewhere a few months ago - there was a difference but, as far as i can recall, not a dramatic one.
there will probably be a difference, mainly in RAID5/RAID6 write speed.
another question is the number of ethernet connections - unless you use 10gigabit ethernet, it may be the bottleneck (PowerEdge R720 has 4 gigabit ethernet ports, or 2 10gigabit as an option). for example, 2xgigabit ethernet is 200mb/s, much lower than the array, and no difference 512mb vs 1024mb could be noticed.
for 5 drives there is not much choice - i think you should use RAID5 (and maybe consider RAID6).

Thanks.... I suppose the speed will be limited by the NIC anyway..... +REP
