Mobility Digest Review: Tmart 16gb Class 6 MicroSD Card

I think microSD cads are the most popular type of storage out there for mobile related products and their prices are coming down lower and lower. I don’t know about you, but I’m always on the lookout for deals and I never seem to have enough storage for my portable devices. Recently a company I never head of, Tmart, approached me asking to review some of their products and one of them they offered was a very inexpensive 16gb microSD card so that’s what I have for review today. The card is a no-name brand but it’s a class 6 card, and I was very curious to see how an off-branded and very inexpensive card might compare to name brand ones so I said sure I’ll review it. So read on for  a quick review…

What’s in the Box?


Tmart keeps prices down by not having any special packaging for their products, it’s just a zip style bag with a sticker on it.


Inside of the bag you’ll find a plastic case with the microSD card and an SD adapter.


It’s a mciroSD card, they all pretty much look the same. This one doesn’t really have any identifying marks on it. There’s a holographic style sticker on the back which I can’t make out at all, so I don’t know who actually manufactured this card.




Impressions / Review:


For testing I used my in-bay card 3.5” USB 2.0 reader, that’s how I test all of them.

For testing I used ATTO Disk Benchmark and Crystal DiskMark, here’s the raw test results from ATTO:


Then here’s a handy comparison chart of many microSD cards I’ve tested in the past. They’re all varying speed classes, but it gives you  a good idea of where they stand in terms of performance.

The Tmart Class 6 microSD card comes in at the lower end of the chart, but it’s about average really in terms of performance, it’s not super fast but it’s not horribly slow either.

Class 6 cards are supposed to hit at the minimum 6mb/s for write speeds and this card well exceeds that.


Here’s the Crystal DiskMark results:

They’re close to the ATTO scores. I run the second test to get an idea of the speeds for comparison and verification.


As far as price, right now Tmart is selling this card for $10.99 with free shipping. I checked Amazon and I thought I had found one for cheaper at $8, but then I looked at the shipping cost which was $6.54 putting the total up to $14.54 and the brand is INFONONLINE which is something I’ve never heard of. So right now, as it stands, this card is the cheapest on the market I think…





For the price this card isn’t bad at all and the speeds are about average. The read speeds are more than good enough for HD Content as the write speeds are as well, so it’s good enough for most any use surely.

As far as longevity, who knows, it’s an off-brand or no-name brand actually, so you never know, it’s a gamble. I’ve bought name brand expensive products that have died before their time, and I’ve bought generic ones that have lasted forever. You never know what you’ll get really when it comes to anything, name brand or not.

So I say why not, it’s an inexpensive way to add more storage and it performs well overall.



+Decent speeds overall
+Comes with adapter


-Not the fastest
-No-name brand
