SanDisk Ultra 64GB micro SD Card Review


It seems that everyone has a mobile phone or tablet today, as there compact so many individual things (music player, e-reader, camera, GPS, and phone just to name a few)  into one small portable device.  The problem with many of them is the limited (and expensive) storage premium, and keep in mind that the operating system can take up a good bit of this space, depending on your OS allegiance.

Even when you have expanded storage options, you can still be limited by what can be put on this memory, but that is a topic for another article.

Most people use micro SD cards to house their digital media (music, photos or videos), and for that purpose a plain-Jane micro SD card works just fine.  A problem arises when you need a faster card, such as when recording HD video, taking camera snapshots in burst mode, or loading a large game.

Thankfully micro SD storage costs have come down in price considerably within the past year.  Most modern devices now support micro SDXC, which currently tops out at 64 gigabytes (as of this writing).

The new SDXC specification expands on the SDHC spec (32GB max) by supporting up to 2 terabytes.  It is also UHS (Ultra High Speed) Class 1, meaning that it certifies a 10MB/s minimum transfer rate, but is optimized for high-bandwidth uses.

Why SanDisk?

There are several choices when it comes to maxing out your phone or tablet’s storage slot, but SanDisk is a brand name that can easily be found in most retail stores.   Generic cards are usually very cheap and have a high failure rate, so choose a brand-name card if you value your data.  There’s also a risk of counterfeit cards, so if you buy online, make sure it’s a reputable dealer.  Honestly, micro SD cards are so cheap today that there’s really no reason to take a risk from a site you’ve never heard of.

I’m just saying that if you’re in a retail store then SanDisk is probably the only recognizable name brand choice available.

While there are faster microSD cards, the SanDisk Ultra is the sweet-spot when it comes to price and performance.  “Regular” SD cards (those that don’t specify a Class rating) can have abysmal write speeds (anywhere from 4MB down to 500K per second).  The Ultra is a Class 10 card that boasts speeds up to 30MB per second (more on this later).  Additionally, the card is waterproof, X-ray proof, shockproof and temperature proof.

The card also has a bunch of environmental protection (waterproof, X-ray proof, shockproof and temperature proof).  As far as these claims go, if a microSD card is left in your pants pocket and goes through a wash cycle then you’ve probably lost it anyway.  We dropped the card in a glass of water for 30 seconds and pulled it out, and the card performed just fine.  Dropping this card is like dropping an ant from a cliff… it doesn’t have enough weight to cause any damage.  Temperature-proof is relative as every material has its thermal breaking point, but I’m sure that as long as the thing doesn’t melt then it should be fine.  We didn’t test the shock properties of the card, but I wouldn’t recommend performing your own hammer test.
