Looking for recommendations for an sd card in particular anyone has any real life experience of any benefit of super high speed uhs 1 90mb or if a 45 is ok

i know these arent minimums and this is the problem
 
A lot depends on your camera and what you shoot as to whether you will see the benefit of a really fast card.

If your shutter buffer can't match the speed of the card, or you aren't shooting fast paced things like sports, its probably not worth it.

I personally though use Sandisk for Compact Flash. I've been using Transcend for SD cards, not had any issues with them.
 
ive been reading a bit about buffer dumps on to the card, its tough not having a definitive benchmark for sd cards

i was mainly looking at

lexar 32gb 400x
sandisk extreme 32gb 45MBps
transcend 32gb 600x

these are all fairly similar in price
 
I wondered for a while whether a faster SD card would make a difference. I started with a basic class 10 32GB card that I picked up in my local Tesco since I'd forgotten to buy one with my camera. I used that for a while and after reading that it apparently did make a difference, I got myself a 95Mbit/s 32GB card instead.

My findings are that it definitely makes a difference! Normally I don't really manage to get the buffer filled on my 650d with the fast card but today I had to use my slow card in my 70d after I'd filled the fast one and I managed to fill the buffer on two occasions :/
 
I've only used 45MB SD in my SX50 so far, but that never seems to struggle when recording video at 1080p. So I'd expect a DSLR, with superior electronics, to be fine unless you have a niche use in mind. But I suspect the internal buffer and processing will be the main limitations, unless using a slow SD card.
 
From what I read, as long as it's a class 10 card then you won't have issues recording video unless you can find a device recording completely uncompressed video or something but even then I'm not sure.

Still images seems to be where the fast SD cards helps because the buffer can clear a lot quicker.
 
I've got a 90MB/s 16gb Sandisk Extreme Pro SD card, I know it's overkill but I like being able to pull images off it quickly. Others are all 20MB/s - 45MB/s, all seem to work fine.
 
its not the video its the dumping of the buffer to the sd card in burst mode i am thinking of

the camera will be a 70d

ha the 90MB car is definitly extreme! :p
ive read good things about the lexar cards

im only looking at cards 30MB + max speed..its the min i worry about.. there is a sony that claims 90MB max but reviews seem to say not good so i cant just go on rating of the card

I have a similar, but smaller, pile (I have lots of random others but never use 'em unless its an emergency).

The other thing to consider is reliability. You can never guarantee against failure (all electronics fails eventually), but I've not yet had a single Sandisk card fail, where I have had at least one random other fail (actually, it split in half!).

Anyway, write speed definitely makes a difference - most noticeably when burst shooting, but in any event the sooner the buffer gets flushed out the less likely you are to lose photos (e.g. from accidentally pulling the battery).

PS - If you do go Sandisk, watch out for fakes! Buy from a reputable seller.
 
Only card I've ever had fail is a Kingston SD card, which is enough to put me off buying their products.
 
most say sandisk with the 'Pro' version not being needed?

Btw, Raymond, that is a lot of Flash storage! why so many? trips abroad?
 
Yeah, I shoot weddings :) Thanks Andrew for the kind words!

I have had 1 Sandisk card die on me, it died to a point that recovery software didn't work and it could not be formatted but either computer or camera, luckily it was only holiday photos on my backup (compact) camera. Had to RMA it, and I remember making a tweet about it and Sandisk got in touch !

But that was 5 years ago and it has not happened since.
