Access to GoFlex Home 2TB NAS very slow!

[jnandi1]

Hello Experts,

For the past month or so, the access to my GoFlex Home 2TB NAS has become very slow. NOTE: It was screaming fast when I first installed it. I've read post across forums on this issue, and a lot of people seem to face the problem, but haven't quite figured the solution (except in one case where someone changed the entire Linux filesystem and remounted - which is beyond my proficiency level).

The GoFlex Home 2TB NAS and my PC are both connected wired on a Cisco Linksys Wireless Hub/Router WRT110 on 100MBps Connection (although both have Gig NICs). Transfering smaller files is obviously faster than larger files. The most delays are in accessing my iTunes library (which has over 10000+ songs, and my outlook .pst files (which is 3GB+).

I conducted a LAN Speed Test (with 100K, 1MB and 10MB file size). Here are the results. Any advice would be most appreciated.

your read speeds are right on the mark but your write speeds are horrid. Is the drive nearly full?

No the drive has about 500GB on it ... since the original posting, since no one seemed to know what the issue was, I bought a Gigabit switch, Cat5e cables - and now the drive is screaming again ... guess it was a network bottleneck issue (although i can't figure out - like you said why write would be so much slower than read)

It is just as good as it gets.

You have several non-sequential files being copied. Please try to copy a 2 GB file and see the speed if it is better.
Non-sequential files are much slower than big files. Does your NAS have a built-in RAID as well? This could also cause a part of the slowness, since they have "bad" and "fakes" RAID controllers.

Remember, your transfer speed (WRITE is different than READ) is really bad.
Pay attention on this: are you talking about 5 mbps or about 5 MBPS? It is different.
I´ll assume that you are talking about the second one, which is not bad.
I have tested two different brands (which I will not point out) and both had "Gigabit (useless) Ethernet". USELESS since I had the same slowness. It is anoying. I know.

I personally have tried to use one NAS Solution, and most of them, for home usage and cheap prices are just "garbage" equipament to store your files. Have also friends who gave me disks to recover files after crashes. Any NAS without disks costing up to 400 US$ are not worth. Thats my opinion. I would much certainly spend that money to buy a RAID HW Controller and load it up on any server. You can build your own NAS cheaper and better the these ones available on the market.

Today, I use a very thiny Linux with embedded processor, using a good RAID HW Controller as a NAS and I have transfers rates around 45MB/s. Transfers between two good servers around 120MB/s. MB, not mb, which means running full Gigabit Ethernet transfer between good servers, and around 1/3 between self built NAS.
Bye.
