My only complaint about the D750s I own is the relatively small buffer. I decided to see how much I could improve the recovery speed by using a relatively fast card. The short answer is: a great deal.

The cards: Samsung 128GB 80 MB/s v. SanDisk extreme pro 128GB 95 MB/s

The files: stored 14 bit NEFs in slot 1 and normal JPGs in slot 2

Shooting: For both brands I shot at “high continual” till the buffer was full and the timed how long the buffer took to empty. The greater number of shots reflects how quickly the buffer emptied while shooting.

The results:
Samsung: 11 shots and 15 seconds.
SanDisk: 21 shots and 5 seconds

Conclusion: For me, the Sandisk cards eliminates my complaints about the D750’s smaller buffer.

A word of caution....and Thankfully I caught it on time, I run Win 7 on all my computers and refuse to up to Win 10 (won't go into why not, to long a story) so anyway, as everyone else I keep getting the pop up reminders to upgrade and I continue to uninstall the installer (KB3035583 update file) But unless you turn off auto update window, it will return. Well this morning I turn on my monitor, (I never shut down my network) and to my surprise Windows 10 installed itself overnight... I woke to a screen asking if I was who I am and accept or decline the install...I answered No and declined... So my machine rolled back and restored my computer back to Window 7 but took an hour....so beware, they are pushing ....BYW, there is no one that uses my computer but me and I know I didn't okay the install. There is a few articals about unauthorized upgrades, so beware if your one who doesn't want Win 10.

Last night I was trying to copy a DVD via DVDclone on my small LG external CD/DVD writer. The original DVD was of a programme I had recorded from the BBC and recorded on my Panasonic DVD recorder.

DVDclone read the DVD perfectly but then refused to copy it on to a vigin DVD disc.

Frustrated and thinking that the writer had finally broken, I ordered a new one. However, this morning, out of curiosity, I tried an original DVD in the writer again and it worked!!
If using USB on the writer, sometimes changing USB ports helps.
How come? Anyone give an explanation?
