Ultra 16GB SDHC Class 10/UHS-1 Flash Memory Card Speed Up To 30MB/s- SDSDU-016G-U46 (Label May Change) [Old Version]

There are a ton of SD cards out there. Of all the things I spent the most time researching, is which SD card to buy for the Raspberry pi. This SanDisk is about the best one available. Although much higher performance (more expensive) SD cards are out there, the current version of RPi either won't take advantage of speed, or it simply won't work. From what I can tell, 20MB/s is about the best the RPi will do, And for under 10 bucks, this is a great deal!My full Raspberry Pi setup includes:- RASPBERRY PI MODEL B 756-8308 Raspberry Pi B- Edimax EW-7811Un 150 Mbps Wireless 11n Nano Size USB Adapter with EZmax Setup Wizard- Multicomp Clear Raspberry Pi Enclosure (MC-RP001-CLR)- SanDisk Ultra 8 GB SDHC Class 10 Flash Memory Card 30MB/s SDSDU-008G-U46- AmazonBasics Wired Keyboard and Wired Mouse Bundle- AmazonBasics 7 Port USB 2.0 Hub with 5V/4A power adapter- USB to RS485 Converter Adapter ch340T chip Support 64-bit Win7- GearMo® Mini USB to RS485 / RS422 Converter FTDI CHIP with Screw Terminals (I actually bought this RS485 adapter elsewhere, as it was rather expensive on amazon)Overall, the Raspberry Pi is an awesome device, and this SD card was the perfect addition! I hope it will inspire the new generation to learn more about the inner workings of computers. There are very cool online resources, with project ideas such as the adafruit Raspberry Pi WiFi Radio. If interested in RPi, be sure to check out the eLinux (dot org) web site, as it has a ton of great information on compatibility.

Great product for a reasonable price.

No issues working in my Zoom H6 recorder.

I use this in a Canon DSLR a Go-Pro and a smaller Canon point and shot. All work very well with this card. The most noticeable would be the DSLR. In the continuous shoot mode the 30MB/s is a big help. my camera is a little older but coming from a class 2 card this was great it will shoot about 30 pictures in fast succession before it slows down.32Gb is a lot of space - I shoot a lot of pictures for fun (1000 per month) all of my cameras stays on the highest resolution without going to RAW.30MB/s the speed the card is supposed to accept images.The class of the card can be found in what looks like a C with a number in it. This card is a class 10 which is a universal designation for 10MB/s or faster. If you see the cards with C4 they basically are rated at 4MB/s.Dependable:This is my third SanDisk Ultra 32. I had to replace one because I lost it. They've survived some serious abuse with me as well. I like activities that will put any electronic device to the test. ATV, Rafting, Boating, Hiking. Everything I have gets wet once in a while in a while. I washed the card I have had for over a year now in the washing machine then sent it through the dryer and it still works like new.Overall very happy with them especially priced less than 1$ per GB of space. (.75 cents per GB)

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.
