OK my Sandisk USB 2.0 CF/SD 4 in 1 has worked very well ...but the new big MPS files were too much for it.
Naturally I thought well get the new USB 3.0 variant..............then I read the reviews .... apparently really cheap nasty tacky crap. Bent pins the lot!
Anyway the hunt was on for a really well built, from a big named brand was on . The best I could find was The Lexar Professional Workflow model.
Yeah I fully admit I am paranoid about a cheap CF card reader damaging the CF card, and that in turn damaging the Pins on my 5DS R.
Wish they would move to SD or something with robust connection - those needle like pins are mental!
All I can say is its well built great solid cable connection - firm , solid yet smooth, likewise putting the card in very very positive action.
As for the speed ............ technically no idea but a shoot on the USB that said 28 mins to doen load to a Samsung SSD ok on a laptop, but via a USB 3.0 port, now takes 6 mins.
So a great result for £18 

When I move to the PC I will definitely get the complimentary SD SH1 Card reader
Just though I should let you guys no as hitherto I never rated Lexar, for no good reason just a Sandisk man historically.
