7 Fastest MicroSD Cards (256GB, 512GB, 1TB) – Speed Test

7 Fastest MicroSD Cards (256GB, 512GB, 1TB) – Speed Test

This article will cover the fastest MicroSD cards and provide test driven research on what exactly the ideal speeds are for mirrorless cameras, DSLRs, drones, goPros, security cameras, android tablets and Samsung smartphones, and any Micro SD capable device.

Pro tip: The fastest MicroSD Cards will have a minimum speed class labeled V30, UHS-ii, and Class 10 on the SD Card’s details from the manufacturer.

Understanding SD card speed classes is important for those that want to squeeze the best quality out of your camera for both photos and videos.

When consumers search for high speed Micro SD Cards, the advertised write speed is more often than not tailored to the SD Card burst speed… and not it’s sustain speed. The sustain speed is significantly more important and is essentially hidden from the product details. 

Note: We also cover the 5 largest Micro SD cards that exist today. There’s even a 2TB Micro SD Card Prototype.

It’s for these reasons that fast micro SD cards are ideal for photographers, filmmakers, videographers and Vloggers. I’ll be explaining in detail why these fast Micro SD cards (256GB, 512GB, 1TB, and so on) are so quick and how to determine the fastest memory card for your camera or device.

Speed classes of high speed SD Cards

Understanding the many different speed classes that high speed MicroSD Cards advertise can be quite complex.

It’s easy to become confused by the advertised speeds of SD Card manufacturers.

This is because the majority of SD cards only advertise the read and write in terms of burst speed (there’s more to a camera than just burst shots). To help solve for this, manufacturers have created ‘speed classes” that are listed on your SD Card:

For the fastest Micro SD card choice, make sure your SD has the following classes: UHS-ii, Class 10, and V30 (V30 or above for 4k/8k shots).

Let’s make things simple for those who aren’t tech savvy. Below is our infographic on the ideal class speeds for 4K video:

Required class speeds for 4k video on Micro SD

To get the most out of your camera

For recording 4k or 8k video, a SD card with 90-100mb/s of write speed or higher allows for pro-level quality and speed. For example, the video speed (V90 class), the fastest microSD Cards will have sustained write speeds of over 90MB/s. 

Update: Our top pick for professional use is not a surprise: Kingston Canvas React Plus  (Amazon). The reason we chose this card is because it is reliable, fast, and meets the requirements of a fast SD Card (UHS-II, A1, C10, U3, V90).

A strong 64GB alternative to the Kingston Canvas is the Verbatim Pro II 62. It is a V90, U3, Class 10 memory card and I use it for the heaviest tasks out there.

Those who the fastest sd card for cameras (or a similar device) will want to check out the chart below.

Below is our chart on Fast Micro SD memory card speeds:

Sustainable write speedSpeed ClassVideo speed ClassUHSIdeal Resolution
90mb/secN/AV90N/A4k or 8k
10mb/secC10V3011080p or 4k

A higher bitrate settings on your device will results in less hours of recording on your SD. While it varies between devices, my 128gb MicroSD, for example, was able to handle roughly 4 hours of lower bit-rate 4k video. Determining the exact amount of hours is extremely difficult to pin-point, making testing is the best route. (source)

One thing to note, is that if you’re using 32GB for 4k video you may want to consider 128gb or larger, since this is what Samsung recommends. Ideally this size is a bit on the smaller side for extended 4k video recording, especially if you’re looking to create pro-level videography or youtube videos with your android phone.


Why do you need a fast micro SD Card reader?

Why do you need a fast micro SD Card reader

A fast Micro SD Card reader will enable the read and write speeds your MicroSD Card is capable of. The receiving device, such as a pc or laptop, can use an adapter known as a SD Card reader to accept faster speeds.

Depending on what you’re using the micro SD card for, there will be certain benchmarks you want to keep in mind.

This is necessary for getting the speeds you need as a professional that works with photos or video. So if you know you have a Fast MicroSD card, but it just won’t transfer at a quick speed, it’s important to check if you’re using a fast microSD Card reader that is capable of the speed class of your card. (UHS-i, UHS-ii)

How fast is a class 10 Micro SD Card

How fast is a class 10 Micro SD Card

If you’re looking for the fastest sd card for a camera, then determining what a class 10 MicroSD Card means is essential. A Class 10 Micro SD card is one of the quickest and can support 10MB/s (sustained write speed). 

This means it’s fast enough for most pro-photography work using 1080p and 4k. However, it’s important to understand the slower versions are Class 6, 4, and 2; which will give you a better perspective on what is considered slow or fast. 

Update: Now if you’re using a tablet it’s likely you’d want to just use the camera on it along with its base storage instead of a fast micro SD. Particularly the iPad and Android based tablets have very powerful tablet cameras that have improved significantly over the years.

By viewing some of the Fastest Micro SD Cards for cameras (photographers), be sure to check the expensive ones and you’ll find that many are simply class 10 (and rarely lower than that). 

What does V10, V30 mean on a Micro SD Card?

What does V10 V30 mean on a Micro SD Card

V10 or V30 is the video speed class manufacturer give to their MicroSD cards to indicate how many MB per second the minimum sequential write speed is on the card. 

This means that a MicroSD card (the the Sandisk models)with a class V30 video speed can transfer 30mb/sec; proving to be very fast . This level of speed (V30) is the ideal minimum speed to be used for 4k video. However, choosing V60 is only required when you’re looking to create 4k, 8k, extreme studio level work with fast action shots or just want the most out of your camera.

I have researched and tested V6, V10, and V30 MicroSD card speeds and found there is a noticeable difference in transfer speed when using the lower V10 and V6 for very advanced shots (as expected)

Fastest microSD Card for switch

Fastest microSD Card for switch

The fastest Micro SD card for Nintendo switches the Nintendo Sandisk MicroSD. When wondering what Micro SD card is best for Nintendo switch, the one labeled Nintendo switch on the actual microSD card proves to be one of the fastest.

Whats interesting is MicroSD cards are also optionally used for Roku devices which could extend how long your Roku lasts. Although, the primary purpose is to make the retrieval of certain apps and channels faster.

It should be no surprise that when a card is made with the name of the product in mind on it that it’s compatible and works well. Not only is it fast, but it confirms the compatibility amongst these devices.

Which are the fastest SD cards for a camera? (burst speeds for a photographer)

Largest micro SD Cards

The fastest SD card will transfer data quickly and can be determined based on their classification. For example, The UHS-1 & II cards can hit over 100MB -300MB. However, a SD card that is not UHS was known to max out at 25 Megabytes per seconds. If you’re using a camera, then know that this is beneficial-particularly when to comes to burst speed.

So if you’re capturing sports or something where you’re catching a blurry photo, then be sure to check what classification and how fast your SD card is.

Keep in mind that burst photography can be difficult because the just-released cameras can handle a lot more than previous models.

If you’re checking out minimum write speeds, which you should be aware of, know that the speed class (as mentioned earlier) is super important to understand. V90’s, & V60’s means you have a very quick minimum sustained write speed.


Many cameras don’t work well with the super cheap, no-name brand MicroSD alternatives you see floating around online. The fastest micro SD (fastest memory cards) listed are compatible with cameras such as Nikon, Panasonic, Canon, Garmin, Sony, blackmagic and more. 

Speed classes apply to and stay consistent throughout all Micro SD card sizes: 64gb, 128gb, 256gb, and 1TB cards.

Ensuring the fastest MicroSD Card means getting a minimum of UHS-II, C10 and V30 or higher, which is considered the minimal fastest options by experts. UHS-I is speedy and most might be sufficient for a casual photographer, however a V10 is not ideal for professional 4k video.
