    Synology NAS 5.5 hrs to Backup 250GB?????

    Just a quick sanity note - any pointers to whether this is the sort of speed I should be expecting?
    I have a newly installed DS211 with 2 x Samsung F3 2GB mirrored drives.
    Seems incredibly slow, but it's my first NAS so maybe i Have done something wrong??
    I was thinking that 50MB/s - 100mb/s so worst way 1GB in 20 secs..........
    I must have something set up wrong, surely

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    That's slight faster than I get with my Synology 407e with 4 x F1 in Raid 5. With an external USB drive I get about 100GB/hour; to the Synology I get about 50GB/hour which is what you are getting.

    100mb/s = 12.5 MB/s = 750MB/min = 45GB/hour

    That sounds pretty optimistic to me, I don't think the speeds you're getting now are particularly shocking - it's around 13MB/s.

    Yeah, what exactly are you doing - backing up the NAS to a USB drive, PC to NAS over network, between drives in NAS, etc?

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    PC connected to BE Router

    NAS Connected to BE router

    So I am guessing (remember I am a Network N00b) that it should be pretty damn quick - ie 100mb/s

    That is why it seemed incredibly slow.

    I have however been told by a customer today that if I buy a ethernet switch (the faster variety) and wire everything to it that will solve my speed issues - does that sound right?

    http://www.scan.co.uk/products/netge...managed-switch

    Something like this OK to then connect up a wired network around the house and solve my issues?

    (As I will be rennovating a 3 bed largish 100 year old house and running wired CAT6 points into the important rooms as I go )

    As per my calculations above, you are getting over 100mb/s at present. I can only guess that you are on gigabit ethernet already? What speeds are the networking cards reporting as being at?

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    I have the same NAS and was in pretty much the same situation as yourself.

    Previously I had the backup running from PC > WRT54GL > DS211 and that was taking 10+ hours for ~600Gb

    I introduced a gigabit switch a few months back and now everything passes through that.

    I backed up 420Gb from the NAS to a USB HDD connected to the front USB port of the NAS.

    The backup started at 10am and the DS211 emailed me (love that feature) at 14:42 to tell me the backup was complete.

    The time taken to back up from the PC > NAS has roughly halved too.

    As Originally admitted I am a networking N00b - I thought that 100MB's meant 100MB's per second - DOH

    That sounds very encouraging, thanks m8 So in respect to the first quote how does that make sense?? I am confused!

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    250Gb in 5.5 hours = ~250,000 Mb in 19,800 seconds = 12.63 Mb/s

    Log into the NAS, open Resource Monitor and click on Network Flow to get a bigger graph of your LAN flow.

    Start a transfer and give it a few minutes to find the speed and level off - I regularly see around 20 to 25 MB/s when transferring data to and from the NAS.

    If the above is correct, you should be seeing around 10 to 15 MB/s (10,000 KB/s according to the NAS's scaling)

    Edit: What blueball is saying is your speeds are correct.

    You can increase them by adding a gigabit switch as long as your PC supports gigabit ethernet of course. I went for Cat6 patch cables too, mainly because the Cat5/5e patch cables I were using were old. I'm sure it's placebo but everything appears quicker.

    I've just had a quick look, and across my Gigabit network I can get 40MB/s writing from my desktop to my server, so I would guess that you could beat your current 13MB/s with Gigabit, unless the Synology is horrendously slow.

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    DS211 got 1.6Ghz CPU and 256MB of RAM Jim - its horrendously slow given that it has to calculate XOR parity for RAID5 as well [if you use RAID5 though]

    My QNAP box can handle 100MB/s sustained writes and pretty much saturate the GigE link in reads. That's with 1 NIC, as I got two of them NICs aggregated in 802.3ad, reads can hit 200MB/s fairly easily, only my main PC with Broadcom NIC can do 802.3ad, rest are just plan GigE clients [you need multiple MAC addresses to achieve >1Gbps though]

    I would say CPU/RAM combination is killing you there...

    Re: Synology NAS 5.5 hrs to Backup 250GB?????

    The DS211 will do ~105 MB/s reads under RAID 1 (RAID 5 isn't supported) and Windows and ~54 MB/s writes.

    Granted it's not superfast, but it's not a performance item

    See my sig for my long exploits into NAS territory. Or the short version is to get a Gigabit switch to connect the NAS to your PC, and then plug the switch into the router.
    I'm commenting on an internet forum. Your facts hold no sway over me.

    Sounds like a switch is the way forward - i need one to connect a wired network to the rest of the house anyways - is something like this the best solution?

    Well I personally always recommend ZyXEL switches, they're much cheaper than the Netgear ones and it's not like there's any difference in performance - unmanaged switches all perform pretty much exactly the same i.e. wire speed.
