News - BT to test 1Gbps broadband within months

[Jay]

the VelociRaptor will do 130MB/s write

and the WD Black will do over 135MB/s write

so they could saturate it.

Finally....me little Ramdisk will show its true value (btw Sisoft Sandra reports 5Gbs read/write values). I`ll use it as a buffer then and bring it on BT . If they give me the 1Gbps i`ll take care of it. So not to worry me dear sir, we have the hardware. Just a little server with 4 SSDs in Raid5 is waitin` to be challenged. And because the poor little thing is on SAS expander have some spare room for additional SSDs about 10 extra.

These 100Mbps+ services are interesting but little more than marketing gimmicks at the moment. There really is no need for more than 100Mbps for a home connection as things stand. Then again even BT state that this is really more about showing what the technology is capable of rather than a practical offering. But I even take this with a pinch of salt because if it's fibre then there is almost no limit to the speed it could run given the right optics at each end.

If it's fibre to the premises then 1Gbps could be useful in some scenarios such as a block of flats.

It is possible to pull more than 100Mbps down from the internet even for a home user but only for large file downloads. I'm not aware of any streaming type services that need more than 10Mbps at the moment so a 100Mbps connection would easily support enough of those for a whole house. Large file downloads could saturate the connection but these are not normally time sensitive so these could be controlled with a little QoS to ensure that multiple 10Mbps stream don't get impacted.

So no need for now but could be useful to have more than 100Mbps in some scenarios. However I remember thinking how great 512Kbps was when I first got ADSL but that seems pathetic now. 100Mbps seems great now but I'm sure we will be wanting more in 5-10 years.

Woohoo look, I'm getting the countries biggest penis within months.

However I wont have enough blood in my body to get it hard so it'll be no use to anyone..

Is that real drive performance or market quoted figures.

Only the most expensive SSD's and HD's will perform this well.

Even the Velociraptor couldn't manage a sustained 125MB/s. In addition these were heavily controlled and optimised conditions. The read/write handling of these programs will have been made to optimum efficiency. Who knows what the read/write speed of your drive would be while doing other things such as playing music/watching a vid or playing a game.

That's the raw linear performance, the pertinent part when writing out huge files, and as your neat diagrams point out, an SSD will easily saturate the link, as will a striping RAID array. But as I already pointed out, you don't need to saturate the link with just one device.

Why does everyone insist on talking about velociraptors like they're the fastest HDDs on the planet? The faster rpm is totally outweighed by the much lower data density conpared to high capacity 7200rpm drives; a 1TB F3, for example, has higher sequential speeds. The only thing the VRs are quicker at is random access timea, which is why they are good OS drives.
