SanDiskUltra 32GB SDHC Class 10/UHS-1 Flash Memory Card Speed Up To 30MB/s- SDSDU-032G-U46 (Label May Change) [Old Version]

I have many Sandisk and Transcend memory cards. I am a photographer and those two card manufacturers are my go-to's. Doing lots of events and headshots I can easily take a thousand photos in a night. This card is constantly being used. I haven't had one problem with any of them that wasn't caused by my loss or mistake. They are stable and if you find a great price worth the money. I have to take thousands of photos regularly and my cards get used and wiped constantly without failure yet.The 64gb if your electronics support it, is a lot of space. Not everything supports these larger sizes as one of my pocket cams just showed me an exclamation point. Then I realized it was due to the card size not being supported. All of my other cameras haven't had a problem but be aware of your equipment's limitations.The 64gb size has saved me many times when I forget to wipe or want to make certain and keep copies of my photos until they're delivered. I can still take more pictures and do other jobs without running out of space. It's worth the money to get the fastest card possible and while not as fast as a CF card this 64GB SD card has saved me many times.

I wanted a single SDXC card that would theoretically enable me to go on vacation and never have to worry about the picture capacity of my Nikon D5300 SLR camera. This 64GB Sandisk Ultra card fits that specification very well. SanDisk cards are very reliable and the capacity of this card allows me to shoot NEF format photos without having to worry about filling up the card. This is a Class 10 card so it is also suitable for recording videos as well. I have not done any benchmark testing on this card as regards read/write speeds so I cannot comment much on that except to say that it subjectively seems pretty fast with my D5300 when shooting rapid photo sequences so the card is able to keep up with my camera.Overall this seems like a good deal for the price point and it will definitely be going with me to Hawaii this summer.

I got this 32GB SD card for my Nikon D800 36.3 MP CMOS FX-Format Digital SLR Camera (Body Only) camera, replacing a SanDisk Extreme 16 GB SDHC Class 10 UHS-1 Flash Memory Card 45MB/s SDSDX-016G-AFFP. I have a CF 32GB card, and so I wanted both cards in the camera to be 32GB.Pros:- Insert the card, format it, and it works- Hasn't failed me yet.- Easy to use!- Fast enough to have no lag on high-shutter speed sport shooting or video. Absolutely no problems here. Not sure why anyone would complain about write speed, as it's definitely enough at least for me.Cons:- None yet. Card performs and operates perfectly.I bought the card because I like the SD card over the CF as the primary because I can take the SD card out and insert it into my MacBook Pro right away without an adapter. The card's performance is perfect for my landscape shooting style, as well as when I need it for my kids' soccer games, where I shoot about 200-350 photos on Ch (continuous shooting high) mode.

Over the years, I have used many memory cards from the Sandisk Ultra-series. Their earlier cards (such as SanDisk Ultra 16GB SDHC SDSDRH-016G-A11) were called 'class-4'. But later cards in the same series were labeled as 'class-6'. Now this SanDisk Ultra 32 GB SDHC SDSDU-032G-AFFP is even marketed as 'class-10'. The cynic in me has to ask: are those the same card being sold at different prices? So I used three different benchmark programs to measure the performance of this Sandisk class-10 card, and compared against my other class-10 SDHC cards of various brands.First, I used a benchmark program called "H2testw v1.4" to find out the write speed for large (1GB) files. This is essentially the same as the sequential-write speed used for SD card speed ratings. To qualify as a class-10 card, the card must be able to sustain sequential-write speed of 10MB/s.Here are the Write speeds for all my class-10 SDHC cards: (Note that their Read speeds are all around 18MB/s, which is limited by the card reader I'm using)- HP CG790A : 15.1MB/s- Transcend TS16GSDHC10E : 14.6MB/s- PNY P-SDHC16G10 : 13.6MB/s- Kingston SD10G2/16GB: 10.7MB/s- Sandisk Ultra 32GB class-10 (this product): 10.6MB/s- Wintec Filemate 3FMSD32GBC10-R: 10.2MB/sAs we can see, the Sandisk Ultra ranked near the bottom even though it still qualifies as a class-10. This looks disappointing so far. However, the results from other benchmark programs ("Flash Memory Toolkit v2.0" and "CrystalDiskMark 3.01") were more impressive. The Sandisk Ultra card delivered excellent write speed for both large and small files, while most other cards performed poorly for smaller files (see pictures I uploaded to 'Customer Images' section for details).Of course, the REAL benchmark needs to be done in the actual application. For that, I inserted each card in my Canon Rebel T1i, set it to save both RAW and JPEG formats, then took 10 consecutive shots in burst mode. The Sandisk Ultra card ranked right in the middle among my class-10 cards in this case. It took 23.8 seconds to save all 250MB of data. For comparison, my fastest card (HP class 10) took just 16.7s to finish, while the slowest class-10 card (Wintec Filemate) took 28.3s.Bottom Line:This Sandisk Ultra SDHC card meets the minimum Write speed requirement of 'class-10' card, and it performs equally well for writing large or small files. That means it will work reliably in any appliance that requires a class-10 card. However, it is not the fastest amoung all budget-priced calss-10 SDHC cards I have tested. The HP class-10 card, for example, gives 40% faster write speed for about the same price, so it is a better value.
