Windows 7: Unable to transfer at Gigabit speeds

Unable to transfer at Gigabit speeds

I canít get anything faster than 5Mbs transfers over my network. This is what I have connected. Iím using a Dlink DIR-655 Router, set to connect at 1Gbps, Western Digital NAS drive, it says itís connected at 1Gbps, and my laptop is set to connect at 1Gbps also. My laptop has a Realtek NIC, with the lastest drivers that I can find. Every thing is set to 1Gbps and, they all connect at that speed, but transferring between my NAS and my laptop, I ONLY get right at 5Mbs. Everything is connected with Cat5e cables, no long runs or anything. Iíve looked at several forums to figure out what I can do to get higher transfer speeds, but nothing seems to help. Anybody got any ideas, because Iím running out of them.

Are the drives setup as a RAID1 by any chance? If so, this drastically reduces the transfer speed of files to this unit.

Generally, the cheaper home NAS units have poor transfer rates. In theory you should be capable of 1Gbps, but the reality is that you will typically get 5 - 10 Mbs maximum. This affects many brands - I had the same issue with a Thecus N2200. Unfortunately, there is nothing that can be done about this, apart from upgrading to high-level NAS solutions which are extremely pricey.

Note that the review ironically doesn't mention transfer speeds, but read some of the comments.

gigabit ethernet speed questions, do you get 3/4 or 1/2 or full speeds
Is a gigabit connection a pure connection at a gigabit OR does the connection adjust speeds lower or higher or what? If you look into the connection data and see no errors and your connected at a gigabit rating does this mean that is a real gigabit or has it negotiated some other speed rating.
