ReadyNas NV+ V2 4 bay questions

BlokeUK - the claim for the USB3 standard is up to 5 Gigabits per second, which happens to be 5x the speed of a Gigabit network. It is also far faster than the internal throughput of the NAS units, unless you have a rackmount x-86 based unit which is designed for up to 10 Gigabit per second networks. The theoretical limit for a Gigabit network connection is 112 Megabytes per second (1000/8 for the 8 bits per byte) although some of the older Pros, the new Ultra 6 Plus and the new Pro6 have recorded 120MB/s. It's also 67 percent faster than the SATA 3 theoretical max of 3000Mb/s.

Note also the operative words "up to" which covers a speed range of from 0 to 625MB/s (the theoretical max). Just for grins, since I have a USB3 Flashdrive (Patriot XT 32GB) and recently installed a USB3 add in card to my desktop (C2D E6750, so not the fastest). Copying from my Pro6 to my desktop a 2874MB file took 42 seconds for an average of 68MB/s. Copying that same file from my PC to the flash drive was inconsistent, the first time the copy seemed to stall so I killed it and the second time it took 184 seconds for an average of 16 MB/s. I then tried a test folder of a variety of file, 657 in all plus 25 folders for a total of 683 MB. The first try from the Flash to the PC took 13 seconds for an average of 53MB/s and the second time took only 7 seconds for an average of 98 MB/s. I then tried to copy the test folder from my PC back to the Flash and the first trial took 98 seconds for an average of 7 MB/s and the second time took 62 seconds for an average of 11MB/s.

The card on which the flash drive was packaged says "up to 90MB/s Read" but nothing about writing, which is always slower than reading. On the test with the 600+ files and the 25 folders it did seem to bog down in the write.
