Best MicroSDXC Cards Available
If you do a Google search for MicroSDXC cards, you are going to see hundreds of results. There are tons of cards available and for the average person, it can be difficult trying to figure out which one is the best, which one offers the most space and which one performs the best. Below, I highlight the absolute best cards on the market below.
What is the MicroSDXC Memory Card?
The Micro Secure Digital eXtended Capacity (MicroSDXC) Memory Cards is a miniature sized storage device that is used in a variety of digital devices from smartphones to digital cameras.
The SDXC format was announced in January 2009 and it supports cards in the range of 64GB to 2 TB. As stated above, these cards small, having dimensions of just 15 mm × 11 mm × 1.0 mm., making it small enough to fit on your fingernail.
What is the Difference Between the 3 Micro Formats?
I think many of you will be relieved to read this section, as it can be very difficult trying to understand the differences between MicroSD, MicroSDHC and MicroSDXC cards. I admit that before starting this blog, I was absolutely clueless myself, but the differences between the 3 memory card formats is pretty simple to understand.
MicroSD, MicroSDHC and MicroSD XC
With so many different types of memory cards available, it can really be confusing trying to know what memory card will work with what device. It is even more confusing when it comes to SD, SDHC and SDXC memory cards as they all are the same shape and at times, each card can be used in varying devices.
The Main Differences Between the 3
Micro Secure Digital (Micro SD Cards) – These cards are only available in sizes from 8MB – 2GB. As you can see, their storage capacities are laughable now, but when released, those numbers were a big deal.
Micro Secure Digital High Capacity (MicroSDHC) – SDHC cards come in sizes from 4GB – 32GB. These cards are some of the most popular on the market these days. These cards can only be used in any device that takes SDHC & SDXC. SDHC devices can use SD but not SDXC cards.
Secure Digital eXtended Capacity (SDXC) – SDXC cards are the new kids on the block and they come in sizes from 48GB – 2TB. You can only use these cards in devices that take SDXC. SDXC devices will be able to take SD & SDHC cards as they are backward compatible.
MicroSDXC Card Sizes
As it relates to the Micro Secure Digital eXtended Capacity (MicroSDXC) Memory Cards, at the moment there are only 3 size capacities available. You can get this card in 64GB, 128GB and 256GB. While the SDXC format can support up to 2 TB, the larger cards have not yet hit the market.
The 256 GB option is a behemoth and it is guaranteed to deliver an immense amount of storage space for whatever device it is used in. Where this card fails is the price point, as it is out of the reach of the average consumer, but it is more designed for those professionals or users who need a lot of storage space.
Both Samsung & SanDisk are the leading card manufacturers of this capacity and it is available in various speed options.
The use of 128GB MicroSDXC cards is starting to grow as their prices continue to come down and people search to increase the storage capacity of their phones. 128GB cards are affordable and they instantly provide a massive increase in storage space for device such as smartphones, video cameras and cameras.
Right now the 64 GB MicroSDXC card is the most popular option on the market, as it relates to eXtended Capacity cards. Prices for these memory cards are extremely low and with many high end smartphone offerings from Samsung, HTC, LG & Motorola, you will often find people buying this particular size to bump up their phones internal storage.
MicroSDXC Memory Card Speeds
With Secure Digital memory cards there are different speeds available. The speeds of the cards determine how fast the data is written. Some devices such as digital cameras often require high speed cards. This is the same with the newer video cameras that use flash memory. They need fast cards as they will be writing huge amounts of data to these cards.
Some SD card manufacturers will use different ways to identify the speed ratings of their cards.
Below is a table that lists the common speed ratings. Also examined is the minimum transfer speeds.
Storage Capacity of MicroSDXC Memory Cards
I have crafted a little table below just to highlight how much data can be stored on the MicroSDXC card. A lot of people will have phones or cameras and would love to know if there is a specific card they should get, based on its storage capacity.
**It should be noted that all the numbers presented in the table below are based off real world numbers. You should be aware that the memory card will be able to hold more or less data, it depends on a variety of factors. The information is just so you can have a general idea of how much the different cards can store.
