Choosing a memory card based on the reliability of the manufacturer. Data loss and memory device stopped working is the most annoying case. Who makes a reliable SD card? Lexar and SanDisk are the two card manufacturers who make really reliable stuff. If you got one that is faulty from them, you’re really unlucky.

I use SanDisk, mostly because it’s more popular in Malaysia, most of the retail shops are selling it. There is also a chance that you bought a fake, but I doubt that. Buying online reduces the risk of getting a fake one.

What should you know when buying a memory card?

criterias-of-choosing-microsd-card

1) Types of card and its compatibility

There are three formats: SD, SDHC, and SDXC (or microSD, microSDHC, and microSDXC, but both micro and full-size cards are based on the same spec). Each format is defined in the SD specification, but they don’t work in the same ways.

MicroSD: Has a capacity up to 2 GB, and can be used in any microSD slot.

MicroSDHC: Has a capacity of more than 2 GB and up to 32 GB, and can be used in hardware that supports either SDHC and SDXC.

MicroSDXC: Has a capacity of more than 32GB and up to 2 TB (although at the time of writing this, 512 GB is the largest available card), and can only be used in devices that support SDXC.

2) Ultra High Speed

The SDHC and SDXC formats can support the Ultra High Speed (UHS) bus interface — faster circuitry that enables data to move at a quicker rate. The two versions of UHS are UHS-I (with bus speeds of up to 104 MBps) and UHS-II (up to 312 MBps).

Not all computer benefits from the increased performance of UHS. UHS memory cards will work in older slots but with a reduced bus speed of 25 MBps.

Panasonic recommends UHS Speed Class 3 (U3) for shooting 4K video. For full HD video, it suggests Class 10 or Class 6 at a push. If your card’s write speed is too slow, it will result in dropped frames and produce stuttering video.

3) Reliable Brands

Buying cards from big brands is always better than buying no-name cards for cheaper. These are the products that carry risks to your precious data. Reliable brands such as Lexar, SanDisk, Samsung provide greater levels of reliability, as well as more robustness, with cards routinely protected against shock, water, and even airport X-rays.
