Recommended Posts

if i purchase a Gigabit pci card and install it on my unraid. will i see a speed increase when i transfer a file from a pc that does NOT have a Gigabit card to my unraid that does?

 

pc - basic 10/100

 

unraid - Gigabit

 

any other benefits ? or w waste of money because other pcs i use dont use Gigabit connection.

 

also do i need special Ethernet cables to use Gigabit cards?

 

my logic tells me to use Gigabit speeds/benefits both pc's would need to have Gigabit cards.

 

i also use a 3com superstack 3 (model4400) to connect all my ethernet cables.

No. you wont notice anything because your switch is 10/100 and the card would switch down to 100MB.

 

If your switch was gigabit, then yes you would if you were accessing your unraid from more then one PC at a time. then in theory each PC could talk at the full 100MB/s (the first several anyways).

 

back in the day, when Gigabit over copper (it used to be fiber only for a while) was becoming available, we would upgrade the switches and servers and leave the desktops at 10/100.

eventually they started to come with built in gigabit NICs.

 

now we are installing 10 gigabit cards in our servers...

umm ok then. ill have to get a gigabit switch...expensive probably not worth it for what i use my unraid for (watching films and streaming music.. maybe if i can get a second hand unit of ebay..can i use my normal ethernet cables with gigabit ? iv not long ago bought loads of  Ethernet cables to re wire my hole home.be a waste of money if i have to re wire and buy new ones.

Gigabit switches (and adapters) are pretty cheap and you can use your existing cables.

Assuming your cables are CAT5/5E they will be fine, they're rated to ~1gbit.

Most people running gigabit now use CAT6 though because it is rated to ~10gbit. You most likely won't see any real difference though.

Gigabit is a very noticable difference when copying files but not streaming, your copies will probably change from around 6-8mb/sec to more like 50/70mb/sec, depending on your drives etc.

Theoretically 100m/bit can go up to 11mb/sec and 1000m/bit can go up to 110mb/sec but this is under perfect conditions so don't expect those speeds.

 

Edit: Ofc if your other PC is 10/100 then you won't get gigabit speeds, as mentioned above, it is fairly cheap to upgrade each box to gigabit though.

While 1000base-T is rated to run on CAT5. in the real world, especially on older or lower quality cable, we tend to see data corruption and/or dropouts.

I would strongly recommend picking up new cables.

 

you can get the very cheap online at places like monoprice.com
