PNY High Performance 64GB High Speed microSDXC Class 10 UHS-1 up to 40MB/sec Flash Memory Card -P-SDUX64U1-GE-A (OLD MODEL)

GREAT PRICE AND GREAT PERFORMANCE!!! I have bought 2 of these! One for my phone and one for my AXIS security camera. I also have my clients purchase these for their Axis Security Camera's that I Sell and Install for them. I am actually an IT Administrator, but our company also happens to do IP Camera Installations too, so I find myself doing more and more of those. Those Camera's are VERY demanding on the type of SD card you can use in them. In fact they only recommend you use one brand. That brand is not this brand, and they cost about twice as much as I can usually get these for on Amazon or N_E_W_E_G_G, but these I find work just as well IF NOT BETTER than the brand recommended by Axis. I have found that it is Hit or Miss with PNY, but with the about 15 installations that I have been apart of now, where we have used these very SD CARDS, and in my own Camera and Phone, these are yet to fail me! And I purchased them both about 8 months ago. So Maybe I'll be posting another review if something happens and one of them fails, maybe I'll change my mind and say never mind, they won't last longer than a year, but at this point I can only say good things, have they get CONSTANTLY Written too, read from, erased, repeat, and they are still just as fast as when I first bought them. So Yeah, they really are a great product! So If you see that certain brand that is recommended by most people, There initials are actually the same Initials for SD, and you see that PNY has these exact brand of card available for half the price per GB, than I would definitely say get the PNY!!! Just make sure its this very model with a 10 Rating, They make other models that I haven't had such pleasant experiences with, but this model you will LOVE!!!!

Possibly the lowest priced, quality 128gb card out. Works as intended and data transfers are very quick, especially when using the adapter or a USB 3.0 connection. Perfect to put in a phone or tablet.UPDATE 8-19-15This card worked flawlessly up to about a week ago; speedy write and load times as well as massive storage capacity. However it all of a sudden stopped working in my Galaxy s5. Followed all the regular procedures (restart phone, take out battery, take out/re-insert card, etc.) and it still wouldn't work. Used the included adapter and used a "chkdsk" command in my computer and found nothing wrong, but the card fails to re-format in both phone and computer.Unfortunate as this may be, I would still recommend this card to others as its the best quality and lowest price micro sd on the market.

I picked this up for my new Alcatel OneTouch Idol 3 cell phone when it was on sale for $69, Best price for a 128GB microSD card except maybe ebay but I don't like to chance buying on ebay. Anyway, I have about 75GB of music and copied all of it onto the SD card and still have tons of space for more music, as well as whatever else I decide to put on it. It's pretty fast for a SD card but don't expect miracle people. Anyway good card for a good price. PNY makes good computer tech so I knew this would be a good purchase. If you're looking for micro SD card be sure you know what your device supports. Not a lot of devices support 128GB or even 64GB for that matter.

I picked this up for my Samsung Galaxy s5 - I wanted to expand the memory. It has worked well for the month or so I've had it. It's easy to use, easy to install and uninstall. I bought it because it was on sale for a cheap price, and it was definitely worth it (I thunk it was about $16 at the time, maybe $20). For that price, it's a good deal. However, the data transfer rate is pretty slow - I usually get a great transfer on SD cards, but this microSD was significantly slower. Maybe thats all microSD's, though. Beyond that, it serves its purpose well and was delivered promptly and well packaged.ProsCheap when on saleComes with an SD slot plug-inReliable so farConsSlow transfer rateDidn't come with a case for the microSD card, just the adapter

Bought this for my 11.6" ASUS X205TA. While I love that laptop, its 32GB internal storage was getting eaten up too quickly. After Windows 8.1 updates and programs like MS Office 2013 I was left with only 8 or 9 GBs of space left, which is far too little for my own comfort.The card reads and writes very quickly. In fact, I've loaded several games (although they are older... like Rollercoaster Tycoon 2 or Unreal Tournament 2004) onto the card and it runs very well with no slowdown. One other thing I love about the card is the fact that it comes with a full size SDHC adapter, which makes it much easier to transfer files between this and my older computers that don't have micro SDHC slots.Overall, highly recommended.

Performance is satisfactory. Nowhere near the 40 MBs Read as advertised. Best that I've attained is 29 MBs Read. Write Speeds obtained are in the vicinity of 9 to 10 MBs. Not a bad SD Card for the price. Good for general multi-media usage only. Think MP3 Players and such. Not suitable for high speed videos and action photos.

I am using this in a Nifty Micro Drive adapter in my Mid 2012 Retina MacBook Pro. This has worked well so far. I am mainly using the drive for extra file storage, but I did move my VMware Fusion Virtual Machine onto it as well, since I use it so little. It worked well enough to be able to run some camera DVR/NVR software and extract some security footage, although I do notice some lag in the operation of that VM. Overall though this works flawlessly for what I planed on using it for, which was just simple file storage to expand upon the internal 256GB drive without forking out the kind of money needed to replace the internal SSD.

This is a review of the PNY MicroSD 32GB class 10 card.I snagged 4 of these during a sale and only wish I had gotten a few more. These have been great in my GoPro Hero3+ Black. No issues keeping up with the video recording no matter what frame rate or resolution I'm using.These have also worked in my Nexus 7 tablet.I've had many problems with SanDisk Micro SD cards previously and have had no issues since switching to PNY.Recommended.
