1384870 2014-09-27 23:35:00 I hear that with this M2 SSD Drives and motherboards that you can get a data throughput of 10 Gb's. Can someone explain that to me? lostsoul62 (16011)
1384871 2014-09-28 01:03:00 It's the theoretical speed of the M2 interface when using 2 PCI-E lanes (some boards/drives only use 1 lane). In practice I don't think any current SSDs are actually anywhere near that fast.
Some of the best drives can exceed the speed of the SATA interface by a little so they benefit slightly from the extra speed of M2 but it's not something you are likely to notice.

I love the Idea of an M2 drive with my OS on it attached to the motherboard, that way the entire system is actually contained on one board. That's got nothing to do with performance though.
Also note the M2 interface can share lanes with other PCI-E slots so using it can reduce graphics performance on multi card setups in theory and on some boards I'm sure I've seen that you can not use some of the SATA ports if you use the M2?

It's also something that you would only see the benefit from if you were an HD video editor which is pretty much what it is designed for.

1384873 2014-09-28 06:47:00 If you do get one / use one it can / or will use 2 SATA ports for its bandwidth.

Could have put one on the new build here. Its got an M.2 slot on it. But then there's only 4 SATA 3 ports. I would lose 2. And only have 1 left, because a DVD would be in one of the spare SATA ports.

Altho there's not much in it now. Only the SSD and a DVD burner. And nothing else. Dont have a GPU in it, using the onboard HDMI

It's called marketing.

1384875 2014-09-29 19:57:00 Thanks dugi - with that explanation I suddenly understand my sad, lonely and previous lack of reason for living in this bewildering universe

You're always a help. :-)
