I used two sets of benchmark programs. One is called 'Flash Memory Toolkit v2.0', which measures the random read/write speed of files between 1MB and 15MB. The other one is called 'H2testw v1.4', which measures the sequential read/write speed using 1GB files. Here are my results: (see my uploaded charts in 'Customer Images' section for details)
- For smaller files (1-5MB), the Sandisk class-4 card gives an amazing write speed of 15-17MB/s, while the PNY 'class-10' card can only get 1-6MB/s
- For larger files (10-15MB), the Sandisk and PNY cards are about equal at around 8MB/s for write
- For huge files (1GB), the PNY did better at 9.5MB/S, while the Sandisk dropped to 5.5MB/s
- The read speeds of both cards are equally high at around 18MB/S (this number may be limited by the maximum speed of my card reader used)
What the above shows is that: When used in a typical digital camera (with file size 3-5MB), this Sandisk 'class-4' card is at least twice as fast as the PNY so-called 'class-10' card. But when used in a HD video camera (sequential writing of huge file), then the PNY card should perform better.
For a card to be marketed as a 'class-10', it must maintain a MINIMUM write speed of 10MB/s. So by this definition, the PNY card does not qualify since it cannot even achieve a MAXIMUM write speed of 10MB/s. This Sandisk card, on the other hand, exceeds the requirement of 'class-4' by a huge margin.
Sandisk seems to be the only flash memeory manufacturer that still gives honest, conservative speed class ratings. Any other manufacturers would have labeled this card a 'class-6' or even higher. As a matter of principle, I rather give my money to a company that promises less but delivers more, instead of to others that do the opposite. At the present cost of about 1 buck per GB, this is an unbeatable deal!
The capacity of this card, as reported by my computer, is only 29.7GB. Note that this is actually normal, because compter people define one 'Giga' as '2 to the power 30', which is 7.4% greater than 1 billion. So 29.7GB comes to just about 32 billion bytes, which is '32GB' according to marketing people.
[Update Dec 3, 2011]
I re-tested the two cards above, using the CrystalDiskMark v3.01. The results are consistent with my previous finding. See my newly uploaded charts in 'Customer Images' for details.
[Update Nov 19, 2013]
The Sandisk card is still working fine after two years in my tablet. It should be noted that I have purchased dozens of CF/SD/microSD cards over the past decade, and only experienced ONE card failure (which was caused by an incompatable card reader). So I'm probably just more careful in handling memory cards. For example, I always make sure to discharge myself electrically before touching a card to avoid ESD zap, and use "Safely Eject USB Device" command to remove a card.
You can imagine how I felt...
This is NOT good quality coming from San Disk and I buy all San Disk and Lexar cards ( for my D500 ).
I removed the card and re-seated it in the phone but to no avail. Next, I removed it from the phone and tried to insert it into my PC reader adapter. It saw that a new USB drive had been mounted but no files or directories were detected. After trying another adapter (USB 3.0) I tried a USB 2 reader. Here's where I'm not sure whether it was the USB 2 adapter or the fact that I left it in the reader for 10 minutes and it eventually saw the drive and directories. I had started reading forums on bad SD cards and apparently the 32GB micro SD card from SanDisk has a significant number of reliability problems. I found dozens of users whose SD card worked for a while and then all of a sudden, stopped. None of the forums that I viewed had any suggestions other than to contact SanDisk for a replacement or to leave it in the reader for a while (in my case it was 10 minutes) and maybe you will be able to read it. In my case, I'm copying over the whole SD card to my PC so that I can salvage the hundreds of pictures I have taken, that have not been copied over already.
Since I purchased this card years ago, even though it's only been used for about 9 months, I can't expect SanDisk to replace it. But, I think SanDisk has a quality issue for 32 GB micro SD cards based on the number of people having the same problem. I gave it one star since I've only been able to salvage a dozen pictures out of the hundreds taken.
My name is Allen from SanDisk support. I am sorry to learn that your memory card stopped functioning and caused you loss. It is an entry level card and is recommended to be used mostly with entry level cameras and mobile phones that don't require high performance cards. However, SanDisk stands behind the warranty on its products. We recommend you to please contact SanDisk support at 1-866-SANDISK or submit a support request at www.sandisk.com/support. The manufacturer warranty on brand new products extends beyond the Amazon.com 30 day return period. We will assist you towards a resolution including a possible warranty replacement.
The cloud then start whining I'm out of space, my Settings->Storage & USB also showed I'm down to like a gig. Woe is me.
Genius idea hits: hey doesn't my phone have, like, an unused SD card slot? Why don't I just get, like, more memory. It's like, 2016 after all.
Went on Amazon, got this card for not even $10.
Turned off Phone. Opened phone (piece of cake, Google it), put it in. Turned on phone, it mounted by itself. Voila now I have another 29.71G and can take random Hi-res pictures without having to constantly go into my photo albums to clean up again! Life is good. (See what I did there? you know, LG? Life is Good? ha)
Just a couple quick notes:
* As usual, "32G" doesn't mean 32G bytes in binary units. Card manufacturers always use SI units to make the storage sound bigger. There's usually a 6.9% delta for Gigs. So 32 * 0.931 should be 29.8. 29.71 Gigs more of storage is what I got which is about right.
* Every time I restart my LG G3, I get a message that the card has been unmounted, and then it mounts again by itself. No biggie, though then I need to remember to go into my Gallery app (see screenshot) to specify any more pictures I take is saved onto the card instead of the phone's internal storage. This is likely more an issue with my phone configuration than the card per se, of course.
