SanDisk Extreme Pro 16gb SDHC UHA-1 with Nikon D800 Review

Author sophos9 - Last updated: 19.07.2012


Hey, so this is a review of Sandisk Extreme Pro 16gb 95mb/s UHA-1 SDHC card. I’m putting it through its paces and doing some comparative testing against other types of card. Most people ask “why should I pay that for a card when I can get one much cheaper?” – in this review, we find out…

For performance, I’ve tested this in terms of its actual performance on a Nikon D800, shooting RAW and on continuous shooting. The practical test was compared against a Sandisk Extreme III 30mb/s compact flash card and a standard Sandisk 8gb SD card.

The results are telling of the price difference.

Sandisk Extreme Pro 16gb SDHC UHA-1
Maximum shots – 26
Calculated write speed – 43.1mb/s

Sandisk Extreme III 16gb 30mb/s CF
Maximum shots – 17
Calculated write speed – 14.4mb/s

Sandisk Standard 8gb SD
Maximum shots – 16
Calculated write speed – 6mb/s

So in terms of real life difference, the Sandisk Extreme Pro UHA-1 has 38% more bandwidth to write images than the standard Sandisk card. Now this might not matter to you as the buffer will do its job until it becomes full then buffer stop kicks in and you are left holding your expensive DSLR whilst it takes an age dumping the buffer to the memory card.

Pricing for the cards are as follows (taken from Amazon UK)

Sandisk Extreme Pro 16gb SDHC UHA-1
Cost – £27.48

Sandisk Extreme III 16gb 30mb/s CF
Cost – £16.95

Sandisk Standard 8gb SD
Cost – £4.10


I’ve owned lots of Sandisk memory cards, from SD through to CF. I’ve never once experienced a problem with any of them. I try to make sure that I format them in the DSLR when I need to. These things are supposed to be water proof and even some have been frozen in ice before to be tested (not that I would try it). The test will be shooting them in Pripyat when we head out in August 2012.


Personally I cannot recommend any other memory for DSLRs. Sandisk products have never let me down so I have no reason to change from them. Yes, they are more expensive than other brands however that price comes with reliability and thats what I pay for. For high end DSLR like Nikon D800, you need a fast card. When you think that Nikon D800 RAW images are circa 50mb, a standard SD card will write at circa 3mb per second – your buffer is not going to last long and you will have a long wait time as per the performance demonstration. UHA-1 cards in my opinion are a must. A SD card writes at speeds around 1/3 slower than compact flash cards however this is offset in price.

Memory is one of the most corrupt sales in the world. Only buy from authorised dealers like Amazon or brand high street stores – if its cheap, its cheap for a reason and in all reality, your memory card will perform badly. I buy from either high street or Amazon, not the Amazon resellers but proper Amazon – they buy in millions of units so prices are very competitive.

In summary, I fully recommend the new UHA-1 SD cards – worth paying extra for the speed and reliability. If you have ever had a failed card, you will know what I mean…

Good review sophos9 – I agree completely. I get so frustrated waiting for my images to be written to my card and on occassions it has lead to me missing the shot. I suppose it’s not too bad for urbex type shots because normally you can afford to wait a few more seconds – the scene’s not going to change much (not unless you’re waiting for that special light).

I’ve never had a memory card fail on me but I also use the SanDisk Extreme Pro 16gb SDHC UHA-1 just for peace of mind and that bit of extra speed. I’ve found it cuts about 1 second off the time I have to wait for a 7 shot HDR burst to write out to the card. (Add up all those seconds over the course of a days shooting and I’ve got an extra minute of my life back!)

I used to love Sandisk. However, I’ve had three failures in the last year. The first two were old, however, I just bought th3 16 gb and after 3 weddings I had a failure. One that couldn’t be saved. Not so sure I trust Sandisk anymore. I’m going back to the 8 gb ones to be safe.
