Unfortunately you will most likely not be able to add a 4Gb interface between your current Netgear NAS and the WIn 7 PC. The Netgear only has GbE interface and will NOT accect an FC HBA. So the With your current set up, the most you could hope to atttain on the SAN would be by aggregating two ports to try to attain 2Gbe. The other issue is thiose are SATA drive only capable of 80IOPS.
For a 4/8Gbe FC controller interface on an entry level storage unit with 4-6 450-600GB 15K SAS drives would cost approx $8-10K starting out. A typical 4-8Gb FC PCIe HBA for the PC or server costs about $1000.
If you have a high I/O you can solve it with 10GbE NIC, FCOE, or 4Gb -8Gb FC HBAs. You qill definitely need a higher IO hard drive like a 15K SAS drive. They have over twice the IOPS that a SATA does, or if budget allows find a sysem that uses SSD. SSD can acheive 2500 IOPS or greater. If you woulf like to call please feel free.
