Everything You Need to Know About Micro SD Card

What are micro SD cards used for?

A Micro SD card is a type of removable flash memory card designed specifically for mobile phones and cameras. Like any flash memory card, it's used to store multiple types of files, including photos, videos, music, or software. It's especially useful for devices that don't come with capacious internal storage. Micro SD is one of the smallest memory card formats available. In terms of size, a microSD card can be compared to the size of a fingernail.

How to buy an SD memory card?

When buying an SD card, you'll need to determine the right speed class, size, and capacity for your needs. Be sure to check what your device supports and consider what speed and capacity you'll actually need.

How long do micro SD cards last?

Micro SD cards can last 10 years or more. With that being said, frequent users should replace their SD cards every few years. For professional photographers or videographers who use up their microSD card often, it's recommended that they have a substantial number of high-quality backup SD cards on hand.

Which is the best micro SD card?

According to Android Central, here are the best micro SD cards:

Best micro SD cards for Android

  • Best blend: Samsung EVO Select - reliable and fast
  • Ultra affordable: SanDisk Ultra - powerful, offers up to 100MB/s read speeds
  • Best for 4K video: Lexar Professional 1000x - capable of shooting tons of 4K video and storing a significant amount of game data; V60 speed classification
  • High capacity options: SanDisk Extreme - optimized for apps, available up to 1TB
  • Go pro: PNY PRO Elite - store app data and record 4K video
  • For constant use: Samsung PRO Endurance - for loop recording in dash cams and security cameras as well as phones with limited memory
  • Heavy duty: SanDisk High Endurance -can withstand accidental drops and harsh conditions, ideal for action cameras
  • Ultra-resistant: Verbatim Premium microSD Card with Adapter - V10 video class speed & up to 80MB/s read/write speed
  • Withstand the elements: Netac 32GB microSD Card - can withstand anything from water to shock, extreme temperatures, and X-ray radiation

Can I use a micro SD card instead of an SD card?

Absolutely! In fact, there's no difference between a full-size SD card and a microSD card in an SD adapter. Even if your device only comes with an SD card slot, you can still use a microSD card in it with the help of an adapter sleeve.

What is the highest GB in micro SD card?

The highest GB in a micro SD card is 1TB. For instance, SanDisk's 1TB Extreme microSD card is the biggest capacity that it has ever sold.

How long will a 32GB micro SD card record?

A 32GB micro SD card allows you to record approximately 90 minutes of 1080p (1,080 x 1,920) Full HD video. If the video resolution is reduced to 720p (720 x 1,280) HD Ready, you can record up to 200 minutes of footage on a 32GB micro SD card.

Why are microSD cards cheaper than SD?

The reason why microSD cards come at a cheaper price than SD cards these days is that they are highly demanded electronic products such as smartphones and tablets. On the other hand, the use of SD cards has lessened, and as a result of lower demand, the price of SD cards is relatively high.

What is SDUC/SDXC/SDHC?

SDUC is the acronym of SD Card Ultra Capacity. SDXC stands for Secure Digital Extended Capacity while SDHC stands for Secure Digital High Capacity.

Each of these cards has a memory capacity range:

  • SD standard - Up to 2GB SD memory card using FAT 12 and 16 file systems
  • SDHC standard - over 2GB-32GB SDHC memory card using FAT32 file system
  • SDXC standard - over 32GB-2TB SDXC memory card using exFAT file system

What is a Speed Class?

Speed class refers to the standard of minimum sequential write speed. The SD Association defines it as a way to identify different kinds of speeds. Each speed class answers different demands for advanced video quality recording.

The three speed indications are Speed Class mark (number in a C symbol), UHS Speed Class mark (number in a U symbol), and Video Speed Class mark (a V symbol followed by a number).

These symbols with a number indicate minimum writing speed. It's recommended that you use a fast bus mode that does not affect the memory write speed.

For instance, C10 is used in High Speed mode or faster; U1 and U3 are used in SDR50/DDR50 or faster; V60 and V90 are used in UHS-II mode or faster.

There are four different speed classes—10, 6, 4, and 2. Class 10 is the fastest, suitable for full HD video recording and HD still consecutive recording. Class 2 is the slowest, suitable for standard definition video recording. Classes 4 and 6 are both deemed suitable for high-definition video recording.

In general, you'll want to go for a class 4 or 6 card for a digital camera, smartphone, or tablet. If you're shooting high-resolution videos or RAW photos, then Class 10 cards would be your best bet.
