PogoPlug Series 4 questions and advise wanted.

[hpglow]

Still have 9 hours to go on the resize. So I decided to test my new setup with a USB 3.0 Flash formatted EXT3 drive while I wait. Plugged into a normal desktop I get 90 MB/sec reads and 19 MB/sec writes. Connected to the PP series 4 it writes at 12 MB /sec until the ram gets full and then drops to 7 MB/sec. Reads range from 7 to 9 MB/sec but seem to actually speed up over time, I only had a 180 MB file (my BluRay rips are on the drive being re-sized) so nothing big enough to find out where it capped off at. The other thing of note is that the only avalible computer is connected wireless and it has never been a great performer in the first place so these arn't good benches just something to pass the time with.

I'm looking forward to seeing what a HDD with a 64 MB cache will do once it gets done resizing. Then the real tests being HD streaming playback on the PS3 and other devices.

I haven't converted my HDD to EXT3 yet. After the fiasco I had just to get a 1G swap I'm kinda afraid. I may just go buy another 3T drive just so I don't have to deal with resizing a partition again. As it sits I'm seeing 6 to 8 MB /sec writes and 12 to 15 MB /sec reads. So opposite what I saw with the usb 3.0 Flash stick.

The CPU is near pegged but not quite when reading so there must be another bottleneck causing NTFS peroformance to be so bad possibly the low amount of ram. Not that I can do anything about it other than re-format to a native file system.

The NTFS driver sucks. Simple as that.

Took the plunge today. After a long debate I formatted EXT4. It was a pita, I couldn't make it work connected to the PP series 4, I had to unplug the drive and walk it over to an actual computer and format it. After that it worked just fine. It got it's true test today I had two computers uploading (one was averaging 10MB/sec) to it while it was streaming to the PS3. No problems, no network errors, no hitches. Before it would cause errors just to stream with one upload, so far I'm impressed. Haven't tried 1080p HD content yet but I just don't see there being an issue.

Once I get all my data back on it I will run a download benchmark.

No change in read speeds, writes went up on average. I guess 12 to 15 MB /sec is just the limit for this device or for my network. The device did get some memory back with the swap to EXT4 so that is something. I'm not complaining, I use this device primaraly for media streaming and for that it does a fine job. 12 MB /sec will allow me to stream up to 96 Mb /sec HD content, or multipule lower res streams. ATM I have only checked it with 5Ghz wireless, I'm sure 1G wired would be better, and 2.4G wireless would be worse. But I don't think it can go much faster than it does, I'm pretty sure either my router or the 800 MHz CPU in the PP are holding it at around 15 MB /sec. Which would beg the question...Why put SATA and USB 3.0 on it?

I'm going to do some updating to my wireless router settings to see if I can squeeze a tad more out.

EDIT: I was able to get a tad more download speed to 16 MB /sec by raising my MTU to its max (my DSL modem maxes out at 1492 so I had the router set at that as well, as long as it dosn't hurt my pings while gaming I will leave it there.)

15 mB/s maxes out your wireless. Remember that 300/270 mbit is the signaling rate, effective data througput is about half of that. If your connection is wifi g @54, its maxed out at aboout 27mbit/s data rate if you are lucky. I get 12mB/s over 5ghz wireless from linksys wrt610n v2/e3000 with dd-wrt @ 300 connection rate to my mac.

No, it's difficult to implement full-duplex in the same band as it will cause self-interference.
