Is there any need for greater than a 3G SAS backplane for homelab?

Hi

I'm looking at getting a 12 bay supermicro chassis for my homelabs xpenology storage system. In New Zealand, it is hard to get anything remotely cheaply so I have to look at the bay which leads to high delivery prices.

I've found an older SES2 3G SAS enclosure which fits within my budget but being 3G I'm concerned about whether its worth it compared to the 6Gs which would be double (at least) due to delivery etc.

For general raid 5/6 spinning arrays with a couple of SSDs for games storage, am I likely to run in to any trouble? With 2,400mb/s available on the HBA, 10 drives would give a total throughput of 1500MB/s at most so there is plenty of capacity there... but I'm more concerned about the SSDs as they would be throttled to 300 each.

Is it a concern? Should I be worried for my homelab? My vSphere hosts run 6G SATA SSDs on the hosts so this storage system is for general stuff, games and a couple of shared VMs.

Cheers

Chris

Right, another question... I've found what looks to be a reasonable deal on a C2100 with all the caddies intact and rails. Given that I'm looking at a simple storage server for Xpenology, this seems like it might fit... I understand that the C2100 seems less robust or feature complete compared to say a R510 with 12 3.5" slots but is there anything I should be worried about?
