I might have been lucky, but in the one home and one office were I've connected 10gbit switches and PCIe cards, it has just worked. Especially the office was a nice surprise, because it is at least 20 meters (probably more) of unknown cabling and at least one unknown patch panel between the utility closet where the NAS lives and the desk area. The cables were run 15 years ago, so I expected it to be cat 5, but clearly not.

It is nice moving/streaming large files across the network at 10 gbit. It really is ten times less waiting than with plain old gigabit.

Of course, most of the time I'm working with lots of small files and then the spinning disk array in the NAS has no chance to saturated the this giant pipe, or even a normal gigabit connection...

FWIW, Cat 5e supplanted Cat 5 25 years ago.

I know when I was doing some custom wiring in a house around 2005-6, it was clear that cat-6e was the thing to use if you wanted any future-proofing.

So I bought a reel of that even though I was only going to be using 1000-BaseT. I don't remember there being too much premium on the wire itself.

[loeg]

Do you mean Cat 6 or Cat 5e? Cat 6e isn't a thing and 6a didn't exist in 2006. 6 was certainly more future-proof at the time, although arguably 5e is still fine even today. (Super-gigabit consumer equipment didn't really exist until the last five years and it's till notably more expensive and less common than gigabit, which runs on 5e just fine.)

[saltcured]

Cat 6 for sure. I thought there was some extra tweak beyond that, but I probably misremembered after all this time. Perhaps it was just that it was plenum-rated..

[globular-toast]

You might be thinking of cat6a which officially supports 10G over long lengths, unlike cat6.

[saltcured]

Nah, it was definitely around 2006 which seems to be before cat 6a was ratified. So I couldn't have bought a reel marked that way...

Did you check the jackets? I've got Cat5 (no e) marked cable running 10gbaseT. A lot of cable exceeds the specs on its jacket and specified wire provides enough signal to noise for the provided length in dense conduit. When you have shorter runs, without dense wiring, lesser cable can work.

[apelapan]

I can't see the cable jackets. There's just outlets in the walls. I ask building management to make a link between outlet X and Y and then they make it happen via one or more patch panels that I don't know where they are. :-)

People downthread has written, cat6 was already the goto thing 15+ years ago so perhaps that is what they put in when the office space was built. It is a well built office!

[kstrauser]

Same. I ran CAT6 from one end of our house to the other, because my home office is in the opposite corner as the fiber coming in to the router. After running that, and manually crimping everything, it Just Worked from the first time I turned everything on. That felt pretty good.

Man I wish I had the kind of money/hardware to get 10gbit disk io out of a nas.

[apelapan]

€200 buys you a 1tb ssd even at todays elevated prices. That has no problem giving you 10gbit of sequential io.

Four or five 7200rpm disks in an array can also sustain it for sequential reads of big files. That costs less than a gaming laptop.

A potato can saturate a 10gbit line if the data is mostly in memory.

For lots of small files in random sequence and cold caches it gets a lot harder.
