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.
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.
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 Micro SD cards are so fast and how to determine the quickest 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 most 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).
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 no surprise: Kingston Canvas React Plus (Amazon) since its reliable, fast, and meets the requirements of a fast SD Card (UHS-II, A1, C10, U3, V90).
Below is our chart on Micro SD memory card speeds:
|Sustainable write speed||Speed Class||Video speed Class||UHS||Ideal Resolution|
|90mb/sec||N/A||V90||N/A||4k or 8k|
|10mb/sec||C10||V30||1||1080p 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)
What is the fastest micro SD Card reader?
To get the most out of your camera and high speed memory card; you’ll need a fast Micro SD Card reader. Some are better than others and the fastest, more expensive SD cards may come with a high speed SD Card reader.
Prograde is the fastest UHS-II MicroSD Card reader we tested and outperforms others due to its USB 3.2; allowing up to 1.25Gb/s (10GB/s). This is extremely fast and enables you to get the most out of your Camera & SD Card.

The Prograde 256GB Micro SD Card is one of the fastests, providing 130mb/s write speed and 250MB/s read speed. This allows extended recording of video footage at 4k.
Why it’s so good: The Prograde has become popular amongst the fastest SD memory cards due to it’s V60, UHS-II, class 10. This SD Card aims for consumers to get the most out of their cameras
For a MicroSD Card like Prograde, it’s important to have a UHS-II reader. I’ve tested and used the Prograde USB 3.0 card reader to get over 90MB/s read write in combination with very fast card.
Sd card recovery software: The ProGrade outshines other 256GB SD Cards by allowing for video and photo restoration software in the rare case the card becomes ‘corrupted’.This software combined with Progrades quick MicroSD Card (250Mb/s write speed), makes it one of the best memory cards for photographers.

Unlike other MicroSD Cards, this delkin has a video speed class of V60, and not V30, allowing for roughly 60MB/s sustained write speeds.
Sustained write speeds are the hidden speeds most manufactures don’t show you. For example, V30 MicroSD Cards indicate roughly 30MB/s. So you can now understand why this microSD Card is the fastest compared to others.
2. Samsung Evo 32: Fastest 32GB SD Card (Micro SD)
Who it’s for: Those who want a microSDcard with the highest level reliability in addition to speed will want to check out the Samsung EVO. This card shines for those with phones.
This card outperforms others due to its low-price point and large capacity for mobile smartphones and tablets. This card is very quick for Full HD video. The Samsung evo can transfer 3GB of data in 38 seconds and is ideal for sharing photos and video on smartphones and tablets.This is the fastest samsung MicroSD card from samsung so far.
Why it’s so good: The Samsung microSD Card is fast, strong, and great for recording 4k UHD Video to be used with action camera’s drones, Android devices, Samsung Galaxy, Samsung Note tablets & phones.
This card outperforms others due to its low-price point and large capacity for mobile smartphones and tablets. This card is very quick for Full HD video. The Samsung evo can transfer 3GB of data in 38 seconds and is ideal for sharing photos and video on smartphones and tablets.
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?
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.
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
If you’re looking for the fastest memory 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.
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?
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
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.
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.
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.
