Newbie questions

Installed a drobo 5N tonight, wired to my virginmedia router, and to my great surprise, it works.

So I have started copying files from my desktop. However, I only get about 6MB/sec which seems quite slow. Ive checked the connection on my desktop (via task manager) and it says 1Gbps. I know the internet speed is about 45Mbps on a normal day so I was expecting something more in line with that.

The drobo has 2 4TB Green SATA 6Gb/s 64MB 3.5" Hard Drive, and a Enterprise 256GB mSATA Internal SSD. I have 3.6TB available for Data and about the same for protection.

The computer is connected to the router via 500Mbps Ethernet adapters.

Any pointers?

Also, I was wondering whether Windows home server would work with the drobo?

Thank you in advance

you say “500mbps Ethernet”. that’s not one of the usual standards for Ethernet ports, so I imagine you mean you are quoting the supposed speed of either your wireless adaptor, or, more likely I suspect, your powerline networking equipment.

especially since your computer says it is connected to a 1Gbps socket, that will be the rated speed of the socket on the powerline connector

Almost certainly crappy powerline network is the cause of your slowdown

you say that your internet speed is 45megaBITSpersecond on a normal day and that is what you are expecting… in fact you are getting slightly above that to your drobo 5n which you say is 6megaBYTESpersecond… so 48mbps…

in my experience that would be fairly typical for powerline networking (which usually MAX at about a third of their advertised speed, but typically run way way below that)

either connect to drobo using proper ethertnet cabling, or live with the speed of your powerline Ethernet adaptors.

yes home server works perfectly with drobo 5n,m it just sees it as another network share like any other computer

I hope that’s all clear


Ok, thank you, let me check the mega bit/byte thing!

windows 7/8 tells you file download and copy speeds in bytes

internet and networking speeds tend to be measured in bits :slight_smile:

That is why Im a newbie!

Is 5/6 MB ok though? For streaming to a TV for example?

You should be OK for media streaming over powerline at those speeds - although a very high bitrate 1080p video with DTS audio might stutter.

That speed on 500 Mbit/s AV500 kit is on the low side, you should be getting nearer to twice that. There are a number of things that can cause a slowdown. How many of the powerline boxes do you have? How big is the house? Do you only have one consumer unit? Are the power line boxes on the same circuit? What does the power line manufacturer’s diagnostics program tell you about the speed they are running at?

You’ve opened up a new world of possibilities here!

I have connected the drobo directly to my PC, and I get between 55 and 65MB/s speeds, with networking in task manager at 100% most of the time.

Before it was only 10%…

I will investigate further with your pointers. Thank you.

Powerline networking gear is adversely affected by…
[list][]Power transformers (wall warts, bricks), UPSes and surge protectors plugged into the same outlet bank
]Being plugged into a UPS or surge protector - in most cases communication should be completely cut off, unless your UPS or surge protector is doing a poor job of filtering, though I have seen them work (albeit poorly) plugged into an “Always On” socket of a surge protector.
[]Other powerline communication gear such as Z-Wave, INSTEON, X-10, HomePlug, etc.
]Being plugged into the opposite phase of other powerline adapters. For US folks, standard 2-phase service panels alternate Left-Right as you go down the rows, so AB BA AB - if one powerline adapter is on phase A and the other is on phase B, they will not perform as well as if both were on the same phase. You can get a phase coupler to help bridge communication between the two phases, though be mindful of the compatibility - not all pass all protocols or frequencies.

Usually getting better powerline performance is simply a matter of moving where one of the endpoints is (and getting a longer Ethernet cable if necessary). Sometimes adding additional endpoints can help, if they repeat traffic.
