Wish this can help people with similar situation.
I bought a DroboFS to replace my DroboV2+DroboShare, as it claimed to have a much higher performance. But what I got is far far behind what is claimed.
My DroboFS was having firmware version 1.0.5 . My router/switch is Linksys WRT-610n, with DD-WRT firmware. I have used both Mac (OSX 10.6.6, over 802.11n and GB-Ethernet) and Win7 (over 802.11n). Read performance is around 3MB/s (Yes! more or less the same as my old droboshare, if not slower.). Used AFP and SMB and performance is more or less the same.
After searching thru the forum and someone talked about updating the firmware. Got 1.1 firmware it from http://www.drobo.com/support/updates.php and install, and Boom! performance boosted to around 40MB/s over GB Ethernet. However speed over 802.11n is still not that fast (still 3MB/s, and around 7MB/s using 5GHz… I bet that probably due to my router setting)
One weird thing is, I tried SSH to my DroboFS, tried
#cat some.file > /dev/null
to see the ‘non-network’ performance of my DroboFS. Tried several files, some works file but several of them simply keep running forever (waited for several minutes, while they are only 700MB-1.5GB)
Anyone can give some direction what may cause this? I just feel a bit not comfortable on the strange behaviour… thanks
