I have a WD Caviar Green, 3 TB installed in the Micca using the SATA connection. If I remove that drive and put it in my NAS, and connected it to the SATA port, the drive laughs at the download speed. Because it can handle 6 Gb/s, but at home I only have a 1 Gbps network, so my 40 GB transfers at a little under 6 minutes, I've done it hundreds of times. If I take the same drive to my work and place it on my 10 Gbps network, it takes 2 1/2 minutes, because now the drive cannot keep up with the network speed. So I know the drive is not the problem. I have multiple gigabit devices connected to my home network, they all transfer at 95% - 98 % of 1 Gbps network, so I know the problem is not the network. So the problem must be in the micca device. It's advertised as 1 Gbps network, well I know that it doesn't do that, the best I've ever seen is 100 Mbps. Some folks above stated they have seen it go higher, tell me how you did it? Because, I know the drive can handle it, so that is not the bootleneck. Maybe it's the micca SATA chip, maybe it is advertised as 6 Gb/s or 3 Gb/s (SATA standard), but really, due to processor limitations, can only do 1 Gb/s, maybe only 0.5 Gb/s?
I agree I can remove the drive from the micca device and either connect to my external computer SATA connection, and transfer files at blinding speeds, or I can connect to my external computer's USB 3.0 port and do the same thing. Both of these methods defeat why I bought this device that advertised 1 Gbps transfer speed! Why do I need to install an internal drive if I need to remove it every time to transfer files and then re-connected. That is what I been doing the last couple of years with my existing $49.00 Micca MPLAY-HD media players, that work perfectly fine! I would then have more capabilities, e.g., slow motion, and could have saved myself $170 x 2 = $340. Since when does a upgrade reduce capabilities at 3x the cost?
By the way, I've been doing this kind of stuff professionally for 25 years, I am a Design/Test Engineer. Unfortunately, we can't test commercial systems in our labs, only stuff that goes into space!
