Silicon Power 256GB MicroSDHC UHS-I U3 V30 A2

Print

Companies that specialize in memory cards have had to adapt or die. The market for memory cards has shrunk a fair bit over the past few years as many consumers use mobile devices for video and picture taking. Many wireless handset manufacturers do not implement removeable or expandable storage in their products as they'd rather charge you a huge premium for a device with more storage.

In the past, MicroSD cards were really limited in capacity as well as performance, so they only worked for certain mainstream applications. MicroSD storage has dramatically improved over the past few years and even the mainstream unit from Silicon Power is a bit of a force to be reckoned with. It's not a gale force, but it is a pretty strong contender. Make sure you read more to find out how it holds up.

Introduction:

Silicon Power recently asked if we would like to take a look at a couple more products and we happily agreed! A few of these are exceedingly handy and while they may not be the first company you think of when it comes to storage products, they probably should be. While a MicroSD card may not be that exciting to review, they can be handy - and a slow memory card is a pain in the butt. We'll see how this compares to several other flash storage options in just a little bit.

256GB Superior

 

There's not much to see as you can see in the image above. You get a small, get decent capacity 256GB MicroSD and an adapter. There's not much else that would sweeten the deal, so no complaints here - especially for the price!

On the next page, we'll quickly cover the specifications and features before we jump in and run a couple of tests.


About the SP Superior 256GB MicroSD:

A New Standard For App Responsiveness
With an advanced A2 rating, the Superior microSDXC UHS-I card is specifically designed for app enhancement. Minimum random read of 4,000 IOPS and random write of 2,000 IOPS equate to lightning-fast launches and smoother operation. This translates to an overall superior user experience on your Android-based smartphone, tablet, and other app-running mobile devices. It also saves internal storage space on your device.

4K Ultra HD Never Looked So Good
Life moves fast, so you need a card that can keep up with its speed. With UHS Speed Class 1 (U3) and UHS Video Speed Class 30 (V30), the Superior microSDXC UHS-I card allows you to capture uninterrupted 4K Ultra HD videos. And, since every second counts, read and write speeds up to 100 and 80 MB/s, respectively, ensure that you’re spending more time recording every bit of the action in stunning quality.

Enough Capacity For All Of Your Needs
Whether you're looking to store data on your digital camera, smartphone, drone, portable game console, tablet, or another device, the Superior microSDXC UHS-I card can fulfill all of your needs. With up to 256GB storage capacity, it can store up to 39,400 songs, 75,200 photos, or 12 hours of 4K Ultra HD video. That's a whole lot of data.

Get Out There, Worry Free
We know the best shots are usually not the easiest to obtain. That’s why we’ve engineered this card to be waterproof, shockproof, temperature-proof, and X-ray-proof. So you can get out there and capture those amazing shots without needing to worry. From blizzards in the mountains to scorching hot deserts and the rainiest rainforests, this card is as durable as you are adventurous.

Testing:

 

For the following tests, we compared the Silicon Power 256GB MicroSD to a SanDisk Ultra 128GB SDXC card as well as an ADATA 128GB U3 A2 MicroSD card. All of these cards sit in the same class in terms of speed and we used a good USB 3.1 Memory Card Reader to get the numbers.

Conclusion:

As you can see, the Silicon Power card holds its own against other entry-level-brand cards as well as high-end cards from brand name companies. When you combine 94MB/s read speeds, 64MB/s write speeds, a 5-year warranty and the price of this super affordable memory card, it's pretty hard to go wrong by making it your first choice when shopping for additional storage.

It's quick, affordable and appears to be quite reliable. Overall, it's an easy choice for anyone that wants some extra storage for their mobile hardware. It has fast enough read and write speeds to work well in a camera with the included adapter as well. Fan. Tas. Tic.
