SanDisk 64GB Class 4 SDXC Flash Memory Card- SDSDB-064G-B35 (Label May Change)

works perfectly

I liked how this product easy to use and sustainable for quite long time. This is my 3rd time buying this

So far so good. Pictures are clear and card works well.

I've used these to add storage to computers, digital cameras, GPS devices, and other similar applications. They are also useful for archiving files, and transferring files between devices. But then, anyone shopping for one already knows this. So far I have never had any speed or compatibility issues with this or any other SanDisk device. Having said this, my needs are probably not demanding. For occasional use, and low to medium volume data transfers, I'm more interested in reliability and compatibility than I am in absolute transfer speed. If you must have the very fastest read/write rates, I can't comment. Maybe these are, but I don't pretend to know. In my experience, these have been good, reliable units. The one piece of practical advice I might offer is this: I tend to buy cards with more storage capacity than I think I will strictly need. My reasons are threefold. First, storage capacity tends to be cheaper per data volume in the upper middle of the commercially available price range, high capacity but well short of the very highest capacity available. Second, if storage needs have ever tended to decrease, I have yet to observe it. Third, even if (is that "when"?) a device becomes obsolete, one can probably salvage the memory card and use it in some newer, more modern application. And that newer, more modern application may well come with a higher storage utilization than that of the obsolete one.

I've purchased many of these for critter cameras around my property. They work exceptionally well, but I have an ongoing issue with the sliding tab on the side that is used to lock out recording or erasures. When the card is inserted into the camera, the action often causes the tab to slide down, locking out the chip and preventing recording. These need to be redesigned so the tab has a 'click' detent for the On and Off position which will avoid unintended movement.

It’s great! No viruses (I checked) and I popped it into my dsi for modification.

Excellent

Bought this for Mercedes ML 350 radio hard drive. Transferred my music from my computer to the card. Put in my Mercedes ML350 slot and it copied to hard drive perfectly. I bought this one because of the price and it had to be that kind of card.
