Hi, I am new to readynas. I just bought an Ultra 4. At same time I bought 4 Seagate Barracuda Green 2TB SATA 6Gb/s, (SATA 3.0), 64MB Cache, 5900RPM, 3.5". I installed the new discs in the new U...
Read and write speeds on any ReadyNAS will vary depending on the drives used at each end, the operating systems used and the file structure. When copying files from my NVX to an external USB drive, I can sit and watch the file copy rates fluctuate depending only on the type of file. It seems the slowest when it hits my e-mail folder. Late in 2010, I did not tests using my then new ReadyNAS NVX equipped with 4x1TB Seagate ST31000528AS drives (it currently only has two of those plus 2xHitachi HDS5C3030ALA630 3TB drives). Because my PC at the time was a triple boot (Win7 HP 64bit, Win Vista HP 32bit 2/SP2, and XP Pro with SP3). The fastest of all three was the Win7 64bit which came as no surprise. I used two different drives in the PC, a Seagate ST3250806AS which happened to be the XP system drive (all three OS's were on separate drives, and boot drive selected by the BIOS menu) and a Samsung HD203WI 2TB drive connected to one of my eSATA ports on the PC. The PC and NVX were both connected to a Netgear GS108 switch, and the test file was a 3GB .wmv video file.
Writing to the NVX from the Seagate 250GB drive, 51MB/s. Writing to the NVX from the Samsung 2TB drive was 47MB/s.
Writing from the NVX to the Seagate 250GB drive, 71MB/s. Writing from the NVX to the Samsung 2TB drive was 99MB/s. Since this last exceeded the published specs, I ran it twice with the same result.
Using Bonnie, an x-86 addon to test performance, with the 4xST1000528AS it gave me 110MB/s with 2xST1000528AS and 2xHDS5C3030ALA630 it gave me 108MB/s. Note that this will only test the internal speeds.
The slowest write speeds to my NVX were recorded with XP Pro SP3, also not much of a surprise. Writing to the NVX from the ST3250806AS to the NVX was 36MB/s.
Don't know if this helps or not. You could also try a direct connection to ensure your switch is not slowing things down any.
