   128GB card tested at 88MB/s read, so it meets its claim, August 21, 2015

   Verified Purchase(What’s this?)

   This review is from: SanDisk Ultra 128GB Ultra Micro SDXC UHS-I/Class 10 Card with Adapter (SDSQUNC-128G-GN6MA) [Newest Version] (Personal Computers)

   This card tested at 88MB/s read, so it meets its claim. The 4K speeds are fairly slow at 5MB/s and the sequential write is 15.8 MB/s which should suffice for most applications. This will work well for most people’s needs.

   Tests done on a Kingston FCR-HS3 USB 3.0 reader using CrystalDiskMark 3.0.3 x64.

   Product ID on the package was SDSQUNC-128G-GN6MA
   UPC was 619659133795

   Triple comparison review, August 28, 2015

   This review is from: SanDisk Ultra 32GB Ultra Micro SDHC UHS-I/Class 10 Card with Adapter (SDSQUNC-032G-GN6MA) [Newest Version] (Personal Computers)

   Vine Customer Review of Free Product (What’s this?)

   I was recently offered two of the latest 32GB MicroSDXC cards from Sandisk (the product on this page) and PNY free to review, and of course, I accepted. Additionally, I threw in one of my own personal Samsung 64GB PRO Micro SDXC cards to make this a triple comparison review. MicroSD cards are a common storage media today used in various phones, tablets and action cameras like GoPros, so I’m going to focus this review on the read/write speed of the cards. I speed tested all of the cards with CrystalDiskMark 3.0 using a Transcend USB 3.0 card reader on a USB 3.0 port.

   (Also see below for the attached screen grabs of the results).

   The PNY card scored well achieving its promised 90MB/second read speed and a very respectable 55MB/s write speed well in excess of UHS Class 3 (which specifies 30MB/s minimum write speeds) which makes the PNY card suitable for recording 4K video.

   CrystalDiskMark 3.0 – PNY U3 Turbo Performance 32GB High Speed MicroSDHC – P-SDU32GU390G-GE
   Sequential Read : 90.912 MB/s
   Sequential Write : 54.702 MB/s

   In comparison, the SanDisk Ultra 32GB card didn’t do so well…

   CrystalDiskMark 3.0 – SanDisk Ultra 32GB Micro SDHC – SDSQUNC-032G-GN6MA
   Sequential Read : 82.132 MB/s
   Sequential Write : 15.359 MB/s

   While the read speed is good, for many applications, including still and video photography, its all about the write speed. Unfortunately this particular SanDisk card I was offered for review doesn’t cut it – and as of the time of this review, this is one of their latest cards. I know they have faster cards, but they also charge A LOT more money for them. Additionally, I’ve had bad luck with SanDisk cards in the past including write errors using higher-spec SanDisk Ultra cards in GoPros, and my previous Android phone would randomly dismount the SanDisk Ultra card I was using at the time – and it was a top of the line card at the time… so I’m not a SanDisk fan.

   What I am a fan of is the third card in this triple comparison review, the Samsung 64GB PRO Micro SDXC card. They are super fast, they have been ultra reliable, and they are reasonably priced. This Samsung card beats both of the others in the all important write speed and is only a fraction behind the PNY in read speed:

   CrystalDiskMark 3.0 – Samsung 64GB PRO Micro SDXC – MB-MG64DA/AM
   Sequential Read : 87.806 MB/s
   Sequential Write : 75.562 MB/s

   So if I had to choose, I would take the Samsung Pro card, hands down… and I have! In fact, I own five Samsung Pro MicroSDs and two full size Samsung 64GB PRO SDXC cards that live in my phones, tablets, DSLR and GoPros. And since I started using them over two years ago, I haven’t had a single issue or incident like I have with SanDisk cards in the past.

   So while this may be a review for the SanDisk Ultra 32GB card, I’d say there are much better cards for the money. If you’re looking for a fast MicroSDXC card, you should consider the PNY U3 Turbo Performance 32GB card (also available in 16 & 64GB) or if you want the fastest write speeds and proven reliability, consider the Samsung 64GB PRO Micro SDXC card, which is also available in 16 & 32GB varieties.

   This review is from: SanDisk Ultra 32GB Ultra Micro SDHC UHS-I/Class 10 Card with Adapter (SDSQUNC-032G-GN6MA) [Newest Version] (Personal Computers)

   SanDisk will confuse people with their description and Amazon doesn’t make it any easier. This isn’t truly a uhs1 card based on it’s model number. There’s two types of this card but the difference in appearance in very small. The SanDisk ultra plus is meant for higher end cameras with bigger lenses and wider aperture like the dslr cameras that are rated for uhs1 and gopro hero 4 newer cameras etc. Both cards are rated as class 10, but camera devices rated at uhs1 will demand more and that’s where the uhs1 comes into the equation. This especially applies for newer devices nowadays that will throw as much data as fast as possible onto the sd card per second.

   This SanDisk ultra is for non demanding devices like the plastic Samsung galaxy phones all over the place, or pretty much any cellphone or tablet or older slr cameras. Check your specs! If you payed 2 grand for your slr camera, you probably shouldn’t even be looking at this card. If you use regular class 10 card in a gopro newest cameras or expensive dslr cameras that can take so many pics per second or 1080p recording at 120 fps or higher or any 4k recording etc, then prepare to drop some frames and wont look the best. It will still work but prepare for a headache, even if gopro website specs say only class 10 is needed…… (They’ll list minimum “recommend” specs like every other manufacturer does) Same idea in using only a crescent adjustable wrench to take apart a car engine; you’ll do it but its gonna suck. You need the right tools so get the right card.

   You can use this on gopro hero 2. Not sure about gopro hero 3+. I have the uhs1 in my gopro hero 3 silver. The item in this amazon listing is not the SanDisk ultra plus uhs1. I had to go to Walmart but cost more. Recommended You’re gonna need uhs3 for 4k recording. I hope this review helps someome out there because i was confused and called SanDisk and they were also confused like it’s a different company that’s labeling their packaging, so i had to do my own research. Check the attached images and cross-ckeck model numbers for whatever you want to buy if you’re still confused. Gracias. GIGITTY!!!!
