What Is The Largest SD Card Available

The largest SD card available in the market currently is 1TB. You can find both form factors in microSD and standard SD online.

Here are those manufacturers which provide you the 1TB storage capacity on their memory cards:

  • SanDisk
  • PNY Technologies
  • Lexar
  • TeamGroup
  • Silicon Power

According to SD Association, SDXC’s highest capacity can go up to 2TB. However, we have yet to see any maker supplying this capacity in the market. 

The majority of the card makers still supplying 512GB in the market, only a tiny portion started introducing 1TB in their product line-up.

Why Need 1TB SD Card?

As more people are creating their own video using personal portable devices, the need to store and share this content become imminent.

With technological advancement, creating 4K video has become mainstream and this will require larger storage capacity. Typically, for a 128GB memory card, it can store around 40min ~ 5 hours of 4K video, depending on the characteristics of the video file.

If you have a lot of video files, a larger SD or microSD card is a better choice. The demand for higher capacity SD/microSD cards is trending up yearly. 

Privacy is another reason people choose to use SD cards to store their video and photo files. Although cloud storage allows you to conveniently transfer your file to the cloud and retrieve it anywhere, it may not be as secure and private as an SD card.

Internet connection may be down or unstable at your location. Hackers may access your file on the cloud and service providers may use your file for unauthorized usage. 

New applications like 360 viewings, drone surveying, VR and AR gaming, and AI assist mission tasks are high usage of storage capacity. 

The miniaturization of devices also driving the demand for expansion of memory storage on the microSD card. These tiny little devices are getting more powerful and sophisticated in terms of capturing live data in 3D and moving pictures. Higher resolution will require a larger capacity to store the data.

Newer Gaming device like Nintendo Switch has expanded their card acceptance up to 2TB. This has prompted many SD card manufacturers to increase their storage capacity further. We expect to see more of them increase their capacity from 512GB to 1TB and gradually move to 2TB in the next 2~3 years.

New SDUC Spec allow capacity increase to 128TB

The Secure Digital Ultra Capacity (SDUC) introduced by the SD Association in its SD 7.0 specification can support memory cards capacity to 128TB. The technologies behind memory fabrication and manufacturing have become more sophisticated and advanced. 

With new applications like AI, VR, AR, 3D, 5G, Ultra-high resolution video production, 360-degree photography shooting, more video files are created by individuals so the demand for these devices will drive up and require a different approach 

As consumers and businesses increasingly produce 4K/8K video, more storage capacity is needed. A typical 8K video will consume about 100GB of memory storage for a 2-hour movie. To maintain the quality of the original video, it is advisable not to do any compression, thus larger storage space is required.

SDUC specification is full of forward-looking vision. With 3D NAND Flash memory capable of stacking multiple layers of tiny chips on each other, storing multiple TB of data on a memory card has become possible. This will create a very exciting future, with the metaverse evolution taking shape from now on. 

Are you excited about the new future with your imagination going into Virtual Reality? It is really up to your imagination. As long as humans can imagine, there is a possibility out there.

SD Card Buying Guide

  • before you get your favorite card, make sure your host device is compatible with the SD card you are buying. Some of the host devices still have lower spec than the card you intend to use. 
  • You may consider buying lower capacity card to spread your risk. For example getting 2x512GB microSD card instead of 1x1TB microSDXC card. In case one card faulty, you still have one spare to use and data retent. 
  • get name-brand like SanDisk, Samsung, Kingston, Lexar, Gigastore. These are the establish brands which have stringent in-house testing before they release out to the market.
  • Speed of the card is also important when come to large file transfer. It will shorten the file transfer and copy time.
  • For High-definition video recording like 4K Ultra HD, consider using card with higher writing speed. It is recommened to use card with minimum writing speed of 30MB/s. Therefore, choose card with UHS class 3 and video class with at least V30. 

Knowing what to read and understand the specification of an SD card is important when buying the card you need. Below are those technologies apply on the card:

(1) Speed Class – There are 4 different speed classes consisting of Class 2, 4, 6, and 10. Each represents how many MB/s according to the number assigned.

(2) Video Class – 5 levels of video class starting from V6, V10, V30, V60, and V90 indicating the minimum writing speed in MB/s.

(3) UHS Speed Class – Two classes with U3 faster than U1. The speed is derived by multiplying the number by 10MB/s.

(4) Application Performance – There are 2 classes of Application Performance defined by the SD Association. A1 Class is defined by SD Physical 5.1 specification, whereas A2 Class is defined by SD Physical 6.0 specification and has much higher performance than A1 by using functions of Command Queuing and Cache. 

(5) UHS Bus Interface – Currently there are UHS-I and UHS-II in the market. UHS-II comes with 2 rows of connectors/pins. Using 2 lanes for data transfer, the 1st lane is assigned for the downstream direction (host to card) and the 2nd lane is used for an upstream direction (from card to host).

In Summary

The demand for larger SD card memory storage comes along with the evolution of human needs and technological advancement. As the content creation becomes more sophisticated, larger space for its storage and the speed of accessing and processing this content get more critical. 

You no more need to carry many SD cards with you. With just one 1TB SD card, all your essential information and data is with you. No more worry about data get stolen by others in the cloud. Everything is in your hand within the SD card you carry with.

No more worry about internet connection. No concern on the data plan. You can work anywhere you like.

We hope you enjoy our research on the current 1TB SD card in the market and find one which meets your needs. We will continue to monitor the progress of memory technologies and share those new products with you.

  1. I recently started filming my trips and uploading them to my YouTube channel. The response of my audience has been good. But YouTube’s algorithm has treated me even better because I was able to double my subscribed members in 2 weeks. However, I am shooting in 4K and I need more space. So, a 1TB SD Card is what I need. I have always liked SanDisk.

    • Hi Ann,

      That is wonderful. You will enjoy all your lovely trips shooting in one 1TB SD card. 

      SanDisk has been around for many years, about 34 years since 1988. Therefore, you can trust the brand fully and it is even under big company Western Digital now.
