I'm already running 4x1Gb in a iSCSI/MPIO setup and can get over 300MBps reads. With the built in drives test on my NAS, it should be capable of more, though probably still limited to SATA2 speeds. So I probably wont be able to coax more speed from my NAS over wire, but I'd like to reduce the number of wires running to and fro, and also do away with MPIO. It's not 100% bug free, but so far appears to work flawlessly.
I thought getting into 10Gb would be easy, but so far, I see there alot more then just getting a 10Gb nic and dropping it in the computer. HP SFP cards that only work with specific branded adapters, NICs that cost well over $200
each, different 10Gb standard (this one has me really confused as I dunno if the posters are talking about different types of transport methods/connection, or entirely different 10Gb protocals that manufacturers use on their devices).
I just want to try something new. I always get the tech itch every couple of months, and need to dive into something new on my system/network.
