You went for the buy 1 free 1 promo? I was very tempted actually. I never knew the BlackArmor was so bad. Transfers to my N36L from my PC is close to Gigabit speeds on my Gigabit LAN. I'm getting transfers of about 100 to 115MB/s upload or download.

Looks like the 4 x 3TB WD Red drives in the BlackArmor seems like a waste. Just get the N40L and transfer the WD Red drives and enjoy super fast transfers.

Yeah, I wish I can replace the Maxis router too but then again, I don't rely much on WiFi. For phone and Ipad access, it's ok.

Just use the old fashion clock / stop watch and time the copy process.

Or you can use softwares like Bandwidth Meter to detect your transfers.

Are you intending to put your storage on your network? How many PCs are using the storage?

If you're just with 1 PC, best would be to buy a 4 bay eSATA external box and connect via eSATA. Faster and cheaper.

What? Qnap / Synology 4 bay would cost a bomb.

Seems you're not on Gigabit network? That speed is about right for 100Mbit line.

Too much money for not so much benefit in speed, security and function. My cheapo N36L does 110MB/s transfers although no RAID 5. I'm fine though as I don't store mission ciritical data and at most, I keep important data on a separate drive offsite.

Anyway for consumer use using consumer drives, relying on RAID 5 is not secure enough. It means you're only allowed for 1 drive in your RAID 5 array to fail. If during data rebuild (which I hate that it usually takes super long) another drive fails, then you're in deep shit. That is why RAID 1 for consumer use with consumer drives is still safer.

Else, go for more expensive option of RAID 6 to be used with at least on a 5 bay enclosure that allows 2 drives to fail at once. Else on a 4 bay enclosure, RAID 6 is actually RAID 1.

Your Synology NAS is overkill then because any decent NAS would be able to cope with that kind of workload and transfer.

Are you running full BDs from your NAS? Gigabit routers are cheap. For AV purposes, never use wireless.

I don't trust the speed that Windows displays in the dialog box. I believe that's the average speed it records and not the actual speed the file is being transferred. Best is to time the file transfer with a stop watch from when the actual file starts to transfer and when the file transfer ends. Else, get a monitoring utility like Bandwidth Meter that will record your actual network speed transfers.

Have you tried doing the same (transferring files) over the network between PC 1 and PC 2? Your findings will help isolate and narrow the problem. Anyway, what hardisk are your PCs having?

The transfer from Mybook to PC looks fine but PC to Mybook is a little low. Perhaps the write speed of the Mybook is the bottleneck.

ozak mentioned that he uses the NAS to share files / videos over the internet. Fastest internet speed is 2 to 3MB/s and that is still sufficient for a slow poke network.

But my argument is what's the use of a NAS when it's useful to share with the internet but becomes very limited when shared in the local LAN?

In theory yes, Wireless N can cope with the HD or Full BD bandwidth but the key things to consider with wireless are interference (microwaves, wireless telephones, etc.), dropped connections, lag, latency issues and worst of all, slow speeds when it really counts. Try transferring huge files over wireless and you'll most likely get time outs. With a wired connection, you don't get any of those lag issues which is very important for AV.

Yeah, 100Mbit LAN is also sufficient for Full BD but it's on the limit. You need to account for loss of efficiency and transmission overhead. Sometimes it works but sometimes it doesn't. So why gamble when Gigabit hardware is relatively cheap and available to deploy?

Homeplugs are also not straight forward.

In theory yes. But once you count this and that overhead, and what you receive at the end is peanuts.

No experience with homeplugs but is your house electrical wiring single or 3 phase?
