SanDisk - Pixtor 8GB microSDHC Class 10 Memory Card

I have tested dozens of SDHC and micro-SDHC cards. One disturbing trend I noticed is that: the speed class rating for micro-SDHC is typically inflated. For example, a 'class-10' rating means the card must deliver a sequential write speed of at least 10MB/s. But somehow, a class-10 microSDHC cards is always slower than a class-10 SDHC card from the same manufacturer. Case in point: the PNY 32 GB microSDHC Card (P-SDU32G10-EFS2) claims to be 'class-10', yet it can only write at 8.6MB/s maximum, while the full-size PNY P-SDHC16G10 achieved 13.4MB/s according to CrystalDiskMark v3.01. This SanDisk Ultra 32 GB microSDHC Class 10 UHS-1 card (SDSDQUA-032G-U46A), however, proves to be the exception. It achieved a sequential write speed of over 10MB/s according to two different benchmark programs (11.8MB/s in "CrystalDiskMark", 10.6MB/s in "H2testw v1.4"). This is faster than all my other microSDHC cards, including two 'class-10' cards from PNY and Polaroid. A closer look at the file transfer speed using "Flash Memory Toolkit" revealed another nice surprise: For writing small files, this Sandisk Ultra microSDHC card performed just as well as its full-size counterpart, the SanDisk Ultra SDHC (SDSDU-032G-AFFP). In contrast, all my other class-10 microSDHC cards perform poorly while writing smaller files. See the benchmark results I uploaded to 'Customer Images' for details. When you use a memory card in a digital camera to record HD video, it needs to store a huge video file each session. That means its sequential write speed is most critical. When used in a tablet or a smart phone, however, the card's random write speed for small files is more important. That's why in such applications, the Sandisk microSDHC will perform faster than the PNY and Polaroid cards, even though they are also rated as 'class-10'. [Bottom Line] As of this writing, the Sandisk Ultra microSDHC card ia actually priced lower than other class-10 cards from PNY and Polaroid. This makes the Sandisk the best value - especially if you need honest class-10 performance across all platforms.

I bought this MicroSD card for my Garmin GPS which had run out of internal memory. Adding this card to it has made it work faster and smoother. I can now load newer maps and add-ins to my GPS. I would have bought a larger capacity but the GPS does not support a higher capacity. Performance in harsh winter temperatures has yet to be tested.

I originally purchased a cheap sd card for my camera, and almost returned the camera because it ran so slow. I decided I needed another card or two for shooting special occasions so that I could keep the good photos separate from the random clicks and child-taken photos that are usually filling up the card, and found this one on sale. The speed difference was very noticeable, and I no longer feel the need to shop for a new camera.

I'm writing this review based on my use of it (in a GPS for map downloads and updates): I currently have a Garmin nuvi 2555 LMT that needed a microSD card in order to conduct product and map updates. After browsing around online briefly this was the best price for the overall quality. Having used the GPS/memory card several times since purchasing it, the product has performed excellently with no issues.

The scan disk is very simple to install in your camera, regardless of the brand you choose. The memory preloaded on the disk is very good at all times during operations and does not have to be taken out of the its drive and replaced to get it to work like some other scan disks. The quality of the scan disk is well made with quality control.

I researched best pricing via internet but couldn't find the product on Best Buy website. So, I decided a store visit was necessary because Best Buy almost always has a better product and cost. And you didn't let me down. Your product was $4 less for the same item in other top name stores. Now I know to check with Best Buy first.

I actually purchased this for use in GPS so I could expand my maps for the entire U.S. and Canada. I loaded the disk in the system, updated the maps and used the maps all over Montana without issue. Speed was not an issue for this need but rather memory and it worked perfectly for what I needed.

I previously purchased two of these great memory cards to expand the memory in my phone and my son's. I have been very pleased with their performance. When I saw them on sale again I bought two more to have for my camera. Great deal. I would purchase again.
