Angelbird has built a strong reputation for quality professional media storage, including cards and drives designed specifically for use with ARRI, RED, and Blackmagic Design cameras. Because of that, they are one of my first stops for video and audio recording media.

The AV PRO microSD memory cards come in both V30 and V60 speed classes, covering a vast majority of needs and situations.

Highlights include...

  • Sustained write speeds of 140 MB/s (V60) and 80 MB/s (V30)
  • Shock, moisture, X-ray, and magnetic protection
  • Operating temperatures of -25° C to 85° C (-13° F to 185° F)
  • Sticker-free label = nothing to peel off and stick in slots

Angelbird also publishes and usually meets sustained read and write speeds for their cards. This is something very few brands can claim.

All in all, it's really hard to go wrong here unless you need extreme write speed or durability.

microSD Card Buyer's Guide

Choosing the right microSD cards for recording video can be daunting and confusing.

But, it doesn't have to be.

The following information will give you the knowledge and confidence needed to choose the best microSD card.

Terms to Know

Data Rate

The amount of data that moves from one place to another in a given time.

Throughput

The amount of data that moves through a component or system in a given time.

Bit

The smallest unit of data that computers and devices use, consisting of either a 0 or 1.

Short for "binary digit".

Represented by a lowercase "b" in abbreviations.

Byte

The minimum unit of data historically used to represent a single character of text, consisting of eight bits.

Represented by an uppercase "B" in abbreviations.

Standard

A document published by an authority that defines criteria necessary for effective interchange/interconnection within a system.

Sustained

To maintain continuously.

Sequential

To perform or use in sequence.

Bus

The physical infrastructure used to pass data from one device to another.

Short for "omnibus".

Data Rates

In this specific situation, data rates are the amount of video data transferred per second from a camera or recording device to the memory card.

Because video recording is done continuously and in real time, the memory card must be able to write and store data fast enough to prevent data loss from occurring. And the higher the data rate, the faster the write speed required for the card to reliably write the files.

Cameras and recording devices should always specify the data rates required to write every format, resolution, and quality. This way we know how fast the memory card needs to be in order to work efficiently and reliably.

You can find data rates expressed in either bits or bytes depending on the context. The two units can be used to explain data rates in the same way, just in two different sizes.

The formulas to convert between the two are simple:

  • Bytes = bits * 8
  • bits = Bytes / 8

Prefixes refer to how many thousands of units are represented:

  • kilo = 1,000 (lowercase "k")
  • Mega = 1,0002 or 1,000,000 (uppercase "M")
  • Giga = 1,0003 or 1,000,000,000 (uppercase "G")
  • Tera = 1,0004 or 1,000,000,000,000 (uppercase "T")
  • Peta = 1,0005 or 1,000,000,000,000,000 (uppercase "P")

Therefore, data rates are usually expressed in these formats:

  • kbps - kilobits per second
  • kB/s - kilobytes per second
  • Mbps - Megabits per second
  • MB/s - Megabytes per second
  • Gbps - Gigabits per second
  • GB/s - Gigabytes per second
  • Tbps - Terabits per second
  • TB/s - Terabytes per second
  • Pbps - Petabits per second
  • PB/s - Petabytes per second

IMPORTANT: Pay close attention to prefixes and uppercase/lowercase letters because you will sometimes see them written differently or incorrectly.

Once you put it all together, a data rate of 80 Mbps = 10 MB/s and vice versa, a data rate of 4,000 kbps = 4 Mbps and vice versa, a data rate of 250 MB/s = 2 Gbps and vice versa, and so on.

SD Card Standards

Standards for SD and microSD cards, and their supporting technology, are controlled by the SDA.

The specifications and ratings discussed below are also defined by SD standards.

Every card in this guide is also fully compliant with SD standards.

Read & Write Speeds

This part can be confusing.

Nearly all memory card manufacturers will claim a maximum read and write speed.

However, not all of them will be able to maintain those speeds all the time. Just like an automobile, the maximum speed on the speedometer does not mean the automobile will always travel that speed or can even reach that speed in all situations.

The problem with only knowing maximum speed is that it is unclear where the more stable and consistent speeds may be. Like I mentioned earlier, recording video is a continuous and real time process that requires consistent write speeds.

This is where speed class certifications become important, specifically the UHS ("U") and video ("V") classes. SD memory cards compliant with these speed classes must meet or exceed the minimum sustained sequential write speed for that class.

The UHS speed class is represented by the letter U with either a number 1 or 3 inside. UHS describes the bus type used for transfers, and the numbers stand for minimum sustained write speeds in tens of megabytes per second (10 * MB/s).

  • U1 = 10 MB/s = 80 Mbps
  • U3 = 30 MB/s = 240 Mbps
Icons for SD UHS speed classes
Icons for SD UHS speed classes

The video speed class is represented by the letter V followed by a number. The letter V stands for "video" and the numbers stand for minimum sustained write speeds in megabytes per second (MB/s).

  • V6 = 6 MB/s = 48 Mbps
  • V10 = 10 MB/s = 80 Mbps
  • V30 = 30 MB/s = 240 Mbps
  • V60 = 60 MB/s = 480 Mbps
  • V90 = 90 MB/s = 720 Mbps

Icons for SD video speed classes

When recording video I recommend U3 and V30 class microSD cards at a minimum. All of the cards in this guide meet that minimum requirement.

It is also important to understand that these ratings are for properly formatted cards that are un-fragmented. More about that in the formatting section later.

Bus Speeds

If data is cargo, the bus is the trucks that carry the cargo and the highway they drive upon.

A crucial factor in the transfer of data is the maximum throughput the bus supports. microSD cards with read and/or write speeds that exceed bus speeds will always be limited by the bus speed.

Specifications for maximum bus speeds include:

  • Default Speed: 12.5 MB/s
  • High Speed: 25 MB/s
  • UHS-I: 50 MB/s (SDR50 and DDR50) or 104 MB/s (SDR104)
  • UHS-II: 156 MB/s (Full Duplex) or 312 MB/s (Half Duplex)
  • UHS-III: 312 MB/s (Full Duplex) or 624 MB/s (Half Duplex)
  • SD Express: 985 MB/s (PCIe Gen.3 × 1 Lane), 1970 MB/s (PCIe Gen.4 × 1 Lane or PCIe Gen.3 × 2 Lane), or 3940 MB/s (PCIe Gen.4 × 2 Lane)

The two most common bus speed classifications to understand right now are UHS-I and UHS-II.

The distinction is important when recording higher data rate video formats where UHS-II speeds are necessary, because a UHS-II rated card will only read and write at UHS-I speeds when connected to a bus that is only rated for UHS-I speeds.

One simple way to tell if a card is capable of UHS-II bus speeds is to look at the contacts on the back of the card. Cards rated for UHS-I or lower will only have one row of contacts, while cards rated for UHS-II or higher will have two rows of contacts.

And because bus speed specifications require cards to have backwards compatibility with slower rating classes, it generally never hurts to get a higher rated card than you think you need.

Capacity Classes

SD and microSD cards, and their host devices (e.g. cameras or recorders), are categorized into four different classes depending on the card's total capacity:

microSD

  • 2GB and less
  • Uses the FAT12 and FAT16 file systems
  • microSD memory cards can be used in all current host devices
  • microSD host devices can only use microSD memory cards

microSDHC

  • 2GB to 32GB
  • Uses the FAT32 file system (4GB maximum file size)
  • microSDHC memory cards can be used in microSDHC, microSDXC, and microSDUC host devices
  • microSDHC host devices can use microSD and microSDHC memory cards

microSDXC

  • 32GB to 2TB
  • Uses the exFAT file system
  • microSDXC memory cards can be used in microSDXC and microSDUC host devices
  • microSDXC host devices can use microSD, microSDHC, and microSDXC memory cards

microSDUC

  • 2TB to 128TB
  • Uses the exFAT file system
  • microSDUC memory cards must only be used in microSDUC host devices
  • microSDUC host devices can use all current memory cards

Lower capacity cards like microSD and microSDHC can only use older, and more limited, file system formats that have file size limitations. This can require host devices like recorders and cameras to limit recording times and/or create multiple files during a single recording.

If your host device has been made in the last decade then it should be microSDXC compatible. Therefore, the only cards I recommend now are microSDXC.

If your host device is only rated up to microSDHC, then the 32GB microSDHC capacities of some cards in this list should be compatible.

Be Conservative

As always, just because something is rated for a certain speed does not mean you should always push it to that limit.

Some codecs and manufacturer specifications refer to target data rates and not maximum data rates. Since compression algorithms are not always a constant data rate it is common to see fluctuations around 10%-20% above or below the target data rate.

Therefore, I recommend leaving at least 20% headroom for the rated class speed of any given card.

For example, a memory card with a class rating of V30 should ideally see a maximum write speed of 24 MB/s or 192 Mbps for best results.

This is a situation where leaving headroom never hurts. When recording you want consistency and reliability.

Formatting Your Cards

How and when you format your cards is critical.

If a memory card is not formatted properly or files have been changed in any way while on the card, you can easily end up with corrupted, missing, or incomplete files.

Following this simple workflow exactly will give you the best chances of success when recording:

  1. Ensure every file on the card you want to keep is saved and backed up elsewhere. I recommend using the 3-2-1 backup strategy.
  2. Format the card before every recording session in the camera or recording device in which the card will be used.
  3. If your camera or recording device does not have formatting capability, consult its manual to ensure you format your card correctly using a computer before recording.
  4. When recording is complete, immediately transfer all files from the card directly to another form of storage.
  5. Never edit, move, or delete files directly on the card. This includes deleting files using the camera or recorder. File allocation tables can become corrupted or fragmented, causing data loss and/or slower write speeds.

Diversify

Spreading out your recorded files among multiple memory cards is safer than recording everything to the same card.

If you don't need continuous recording for multiple hours, I recommend purchasing a few smaller cards instead of one larger card.

In general, try to get memory cards that will hold about 1 hour of footage at the data rate needed. That ensures you keep a healthy habit of switching out cards to make sure risk is minimized.

And remember...

One is none and two is one.

Always get two or more cards so you have at least one backup.

Use Proper Form Factors

Lastly, when recording or writing files be sure to always use the matching form factor card for the card slot(s) available.

For example, microSD cards should only be used to record in devices that have microSD card slots.

Avoid using adapter cards to record or write to smaller form factor memory cards in larger card slots. They add many more potential points of failure in the connection between the host device and memory card.

If your host device has a regular size SD memory card slot, then check out my recommendations for The Best SD Cards for Video Recording.

Store Them Properly

Always keep cards in a proper storage case when not in a device.

Look for storage solutions that keep the cards isolated and protected from dust and water.

Be sure to check the actual data rate your specific camera or recording device uses, especially for H.264/H.265/MPEG-4 formats. Once you get up into higher qualities like 10-bit the data rates can vary drastically.

Avoid Counterfeit Cards

Unfortunately, there is a rather prevalent counterfeit memory card market.

Here are some simple guidelines to follow when purchasing cards:

  • Buy from resellers with solid and long-standing reputations
  • When shopping on Amazon, purchase products shipped and sold by Amazon directly, from third-party resellers like Adorama, Focus Camera, or 6ave, or directly from the manufacturer's Amazon store
  • Be sure to purchase products with a good return policy in case you discover the card(s) you receive are counterfeit
  • Immediately after purchase, do some speed tests using Blackmagic RAW Speed Test or CrystalDiskMark to make sure the card(s) meet or exceed the rated speeds
