It really would. My 3x2TB WD Blacks would easily saturate 2 gigabit links, I'd really need 3 in each machine to get full performance out of my file server. Consumerisation of 10gbps should really be going full steam ahead by now. And I'm a bit miffed that it still isn't there. IIRC, 1gbps only took about 8 years from ratification to consumer motherboards.

Easily. Don't forget Gigabit Ethernet = 1,000,000,000bps so just under 120MiB/s (ignoring overheads, which take it slightly lower, but larger Ethernet frames lessen the impact), a basic HDD can surpass that now, let alone RAID arrays and SSDs.

You realise you will need to build a data-centre in your spare room to fill a pipe that wide.
I'm shovelling VMs and disk images between a couple RAIDs and it hardly stresses my Gbe.
I just ran a quick and dirty benchmark, to check my own sanity.
A 2GB file, written to a SATA3 SSD RAID0 and read from a hardware RAID5, comprising 3 mechanical SATA2 disks, maxed at 120MBps and sustained, just about 100MBps (thats bytes not bits) over GbE. The server OS is on a separate mirror BTW.
A 2nd concurrent client, reading from the same array, would drop the speed dramatically, as the bottle neck becomes the speed at which the disk heads can seek. Similarly any writing to the RAID will move the bottle neck away from the Ethernet, as will any small files within a batch transfer.
Admittedly it was a while ago but the last SOHO RAID5 NAS I benchmarked (Buffalo Tera-Station) was processor bound, rather than network bound.
I am struggling to see a need for LAG, outside of multiple clients, reading large contiguous files, from multiple RAIDs. Earlier in the year I built a big dual Xeon, SSD RAID10 server. I considered LAG but rejected it, on the basis the complexity was not worth the performance gain the customer might see in day to day use.Sure, you can use link aggregation,
GbE is frequently the bottleneck when I'm moving large files around. Of course, multiple clients may impact performance if you're accessing different files but the impact can be negligible with some software RAID tweaking, or a decent RAID card, especially if it has a decent cache.
Off-the-shelf NAS boxes are often CPU bound for SMB transfers (they commonly use dated ARM9E CPUs running at a fairly low clock speed), but anything Atom or above should be able to max GbE. Sure, even 10Mb Ethernet would do the same job, just a lot more slowly, and while GbE is enough for most home users, it's still fairly easy to max it and it will become a real problem soon.
Never mind that, a lot of gear still doesn't have anything more than 10/100!!!
Like others in here I'd like a few 10GigE devices. Would be nice to have a server on 10GigE to the switch and then perhaps to key desktop systems. Would make backing up my photo archive a damn site less painful!
Same does for pairing switches together.
What we need is for 10GigE to be like what gigabit was just a few years ago. One to four ports enabled in a switch and semi-affordable PCIe cards for servers (I'm talking well below £100 per card). That would make me upgrade in the right situation.
Do I need 10Gig Ethernet? No, not really. Do I want it? Hell yeah
Generally 1Gig fits within my needs (moving the odd large disk image or video around) and I don't think it's realistically slowing me down that much. I can see a bigger problem with concurrent use though (but in my case it's only the Wife's facebook activity taking bandwidth..).

Me too. I suspect the slow adoption of 10 GbE is down to power usage and the complete lack of a market for home use. It's only really since SSD's that you could in normal use saturate GbE. I know HDD's have been able to do over 120MB/sec for a while now but the difference between 120MB/sec and 150MB/sec isn't that much in the big scheme of things - especially when the vast majority of home users do this very rarely if at all.Generally 1Gig fits within my needs (moving the odd large disk image or video around) and I don't think it's realistically slowing me down that much..
The other problem with 10GbE it in needs CAT6 or Cat6e cable to work.

"In a perfect world... spammers would get caught, go to jail, and share a cell with many men who have enlarged their penises, taken Viagra and are looking for a new relationship."
yep, got that bit, but we are talking Terabits per second, rather than Gigabit, which means that I'm probably going to be a zero out here, but 100,000,000,000bps, which is 1200MBps and as far as I am aware, most SSD's cant write above around 500MBps. As I said tho, I could be out by a 0 or so, which completely messes up the maths.

10 Gigabit ethernet has a max wire speed of 1250MB/sec (ten times GigE)
1Tbps would have a wire speed of 12,500MB/sec (100 times GigE)
1Tbps would strugle to even negotiate at the full rate, I've seen reports of 10GigE only managing a 9000MB/sec connection.
As has already been said, this is a network infrastructure protocal, not something we will see in consumer circles for a long long time, if ever.
As I said earlier up the thread, Ethernet is measured in base-10, so TbE is really 1 trillion bits/s. Wire speed would be 1,000,000,000,000bps so 119,209MiB/s (1000x GigE, not 100). Then you have to take overhead off that at various protocol layers. I've not come across any speed problems with 10GigE, I usually see >1000MB/s goodput when testing.

I knew there would be a 0 missing someplacethanks for finding it bud. I suppose to get anywhere close to that, you would have to have several SSD's in raid format in order to get close to those write speeds. I'm just glad that this part of technology is moving forwards, just need the rest to catch up

It would be fairly hard to max 10GbE with realistic usage at home yet, but it's the next step above GbE which is starting to become a bottleneck in some cases. IIRC when GigE was started becoming commonplace, it was fairly hard to max it and it was normally on the PCI bus so that was also a potential bottleneck, but despite that it still allowed much faster data transfer than Fast Ethernet did.
lol, 1tb/s is totally pointless when write rates haven't surpassed 1gb/s yet.
The only real use for something like this would be for server farms/data centers.

What did you think the intended use was?
