Just got a Synology DS211, kitted it out with 2 x 2TB WDEARs (Green)

Have it hooked to my gigabit port with the supplied CAT5 cable...

am currently transferring files from PC to Synology but am getting awful speeds of between 300kb/s to 1.4MB/s

maximum speed I ever saw was 20MB/s but that was for a single large file...

am using Win 7 64bit enterprise edition

anyone know what the issue is?

thanks:)
 
NAS directly connected to PC? Tested both SMB and FTP transfer? Tested drives with HDTach?

As a side note I would fix the LCC issue with the WD Tool if not already done.

My 4 EADs played up constantly in Raid, I threw them in a corner and got some Samsung F4.

Golden rule...remember backup the backup if the data is valuable to you.
 
no idea what you're talking about mate, am completely new to all of this...
yes the Synology is directly connected to PC (though the CAt5 cable)..

whats LCC and whats the WD Tool?

I was copying all my data to the NAS to make it a central storage server (its in RAID 0)... idea was to read-write from a central source that I would hook up to a wireless modem/router..

however if file speeds are so slow whats the point of having it in the first place... :(
 
So it's connected directly to the PC using a crossover cable? Or your going through a gigabit router/switch?

Personally I would try it with both the pc and NAS attached to a switch and see what the transfer rates are like if possible?
 
LCC = Load Cycle Count, the WD EARS have a strange firmware issue that they park the heads after 8 seconds of inactivity, which means an increased wear rate, this can be set to 8 minutes by using the WD Idle tool (WDIDLE3.exe)
 
the WDs are in the NAS storage box; not sure how I would configure them as they are not connected to my PC.

The NAS is connected to the PC with a direct cable to the mobo ethernet port.

However, the HDD should not have 8 seconds of inactivity as there is a big upload queue on my NAS and they should be constantly writing data because of this...hence they wouldn't have time for 8 seconds of inactivity... :confused:
 
not sure if the above applies as I don't know what my LCC is...how can I determine that?

I checked the HD compatability list on the Synology site before purchasing these and they were listed as compatible
 
ok am now getting 4MB/S write speeds over a wireless (gigabit) LAN... not too impressed. almost full signal strength...This is through mapped drives and not through the Synology CP...

I checked the Synology forums re: WD drives and the only ones with speed issues seemed to be the 1.5Tb and 1.5TB ones..mine are the 2.0TB drives...

:(
 
ok, I just discovered that my ADSL2 modem/router is rated for 10/100 over ethernet so thats a theoretical max of 12.5MB/S... this could be part of the reason..

If I purchase a gigabit switch and connect the NAS, modem and Airport Extreme to the Gigabit switch, would I then be able to increase the overall network speed to a gigabit LAN?

NB, the only reason I would be connecting the Airport Extreme and modem to the Gigabit switch is because the former gives me wireless internet/coverage upstairs and is currently hardwired to the wireless modem router downstairs. Hence if both are connected to the Gigabit switch would I then benefit from a Gigabit network + internet through the Airport Extreme?

cheers

Click to expand...

Part of the reason lol. It's the whole reason. It's a theoretical max like you say and there are overheads.

If you connect everything to a gigabit switch in the way you describe it will work perfectly.
 
ok, I connected the NAS to the Airport Extreme (Gigabit router), through an Ethernet cable...speeds I am getting are approx 2.5MB/s to 3.5MB/S.. this is through a wireless N network... this is actually SLOWER than the 4MB/S I was getting when connected to the 100Mbps Aztech router!

have also recently upgraded the Airport's firmware etc...

not sure what the deal is :(
 
As far as I know the Airport Extreme supports both 2.4ghz and 5ghz bands simultaneously?

Wireless-N on a 2.4ghz band has a max speed of 130mbps (b,g,n) while Wireless-N on a 5ghz band supports up to 300mbps (a,n).

From the sounds of your last post your connected on the 2.4ghz band and being limited to 130mbps. You could also put the slight decrease in transfer speeds down to not having a 100% perfect wifi signal and other overheads.

If you want to do a proper test then you need to get your NAS connected to a gigibit switch and have a PC or laptop that has a gigabit LAN connection connected to the switch also with a cable. It's the only way you're going to see the max transfer speeds
 
Before you fart about with anything else, i'd connect the NAS directly to a PC and see what speeds you get then.
 
approx 58MB/s read and 35MB/s write (this has increased considerably from my first post...possibly due to Windows updates etc? not sure why!)

On a side note I have also updated my WDD drives to park their heads every 5 mins (to address the high LCCs)
