I turned off link aggregation on the switch and turned off network load balancing on the QNAP, reran the ATTO benchmark with the WD green drive, and the results were identical to the test with link aggregation and load balancing turned on.

Ignoring iSCSI for a bit, since I disabled that, I did a Black vs Green speed test using the ATTO disk benchmark tool, which unfortunately only tests small files (up to 8MB). If anyone is interested, below are the charts. These tests use link aggregation and non-jumbo packet sizes. Eyeballing...

For speed testing I used FileZilla as my FTP client and whatever comes with the QNAP OS as the FTP server. For my iSCSI testing I used a 1 GB file, which likely doesn't represent the speed of a small file. I didn't spend much time doing repeatable iSCSI tests since my goal was to see if I...

I used the latest Microsoft iSCSI initiator for WinXP 32 bit, since that is what the QNAP iSCSI instructions use.

I did some quick tests of FTP and iSCSI. On my old server, copying files over FTP to the QNAP NAS was significantly faster than Windows Explorer, by over 10 MB/s. It still doesn't reach the speed of my faster server. On my newer faster server, copying files over FTP didn't result in much...

To clarify the tests I ran, I am doing simplistic copying of files using the Windows Explorer. The servers I used in my tests were both running Windows 2003 Server. I created two files using fsutil, a 1 GB file and a 2.5 GB file (ex: fsutil file createnew c:\1gbfile.txt 1073741824). I will do...

I performed more performance tests focused on the network. I tried link aggregation with a HP ProCurve 1800 switch, plus combinations of jumbo packets and standard packets. Nothing of the network optimizations I performed impacted the speed. I find the speed of the QNAP TS-639 disappointing...

I bought a WD Black drive, which is supposedly one of the fastest 7200 RPM drives around, and performed a series of tests against a 1 TB WD10EADS Green drive in my QNAP TS-639 NAS. Both drives have Feb 2009 manufacture dates. To my surprise the green drive was consistently faster at writes than...

Thanks. I bought a green drive to test. I compared a 1 TB WD Green with an old 150 WD Raptor (since a VelociRaptor doesn't fit into a NAS), and the Green was noticably faster than the 10,000 RPM Raptor. It was around 5 MB/s faster when writing a 2.5 GB file and around 7-10 MB/s faster when...

If I copied an 80 GB file from a computer with a WD Velociraptor drive to a QNAP TS-639 filled with the latest WD Caviar Green 1TB drives over gigabit ethernet, would the bottleneck be the network speed or the hard drive? I am wondering if the speed benefits of WD Caviar Black drives would be...
