82.44 including delivery from BT Shop. Hey you want to get scammed, worth paying that extra to buy from Scan.

Excluding delivery, so the "local shop" option here is cheaper, though OCUK is slightly cheaper if you do want it delivered at £88.69

Are these sticks faster than the normal SSD's?

Yes.
SATA3 is limited to 6Gb/s which means a max of around 550MB/s.
The max read here is up to 1,570MB/s.
Of course, these are theoretical burst values so probably not that useful but they make good headlines.
Don't think this drive performs that well in benchmarks. Here it is vs the now rather old Samsung 850 Pro: http://www.anandtech.com/bench/product/1817?vs=1415
Then again the M.2 drives which do perform very well can suffer from thermal throttling since M.2 is physically so small. On desktop that can be mitigated with a heatsink but in laptops there usually isn't any space.

They are, not that you'd notice, and to top it all this isn't a fast M.2 SSD either, this is a budget M.2 SSD

Yes pretty much so AS long as its a NVME dirve not a sata interface.. this drive is nice but slow compared to other NVME drives eg samsung 960 ..
OCUK have better customer service as well, which is always worth considering. Scans not bad though, they aren't the Curry's of PC hardware, but they aren't as good as the OCUK guys who have always bent over backwards any time I had an issue and thrown in more than a few extras over the years.

Personally I agree with what you say regards OCUKs service.

To bought one of these bit returned it after reading about its low endurance rating. I had the 1tb model but was pretty shocked that you can only write 78Tb of data to it before it locks it's to read only mode to "preserve the integrity of the data". Models, admitedly more expensive, have much higher endurance ratings. This drive only has an endurance rating of 78TBW (terabytes written).
Now, I don't know if I'd ever write 78Tb of data to it over the course of its life, but I don't want that kind of limit hanging over my head every time I use my computer.

Can be done on a consumer (home machine) but not on a 256gb ssd - 1tb or 2tb drive yes - but not 256gb .

Only the 128GB model is 78TB, the 1TB is an order of magnitude higher, at 576TB.
