Almost a year after the The first 1.5 TB microSD card went on sale, a little-known company called AGI has sent Kioxia to the top by putting the first 2TB microSD card on sale, a candidate for our best microSD card buying guide. For just $229 plus delivery (that's around £180, AU$344) from popular US retailer Newegg, the Supreme Pro TF138 commands a premium due to its current status as the only commercially available 2TB microSD card. The card also appears on Amazon.com but hasn't gotten a price yet.
AGI claims the card can reach read/write speeds of up to 170/160 MBps, although that requires a compatible proprietary card reader, the CR138, to achieve these numbers. Other features on its spec sheet include an automatic error correction feature, UHS-1 U3 high-speed protocol, V30/A2 compatibility, and all types of tests (dust, water, shock, magnetic, and X-ray). In other words, the card is fast enough to capture 4K video.
Kioxia announced the first 2TB microSD card, the Exceria Plus, in September 2022 and said it had started mass producing them in December 2023. Now you CAN buy a 2TB microSD for less, there are plenty on eBay, Amazon and Aliexpress, but they are all 100% fake.
But not this one, why am I so sure? To start, they sent us a press release (never happens with fakes) and AGI makes a MANY other products. Finally, it is also worth watching this video of the card launch event, Last month somewhere in Asia.a video containing much more information about the product, including the ingenious integrated temperature sensor.
125 grams of petabyte goodness
Micron broke the 1TB barrier 18 months ago with its 1.5TB MTSD1T5ANC8MS-1WT, a card that It's still quite high priced, almost a year after launch. A mitigating factor is that this is an industrial microSD card, which means it has a much stricter feature set to follow, such as the ability to update its firmware remotely, 24/7 video recording days of the week and an incredible mean failure rating time of 2 million hours. .
Since then, SanDisk released another 1.5TB microSD card, the SDSQUAC-1T50-GN6MA, which costs only $149.99. At the time of writing, genuine 1TB microSD cards can be obtained from Amazon for around $55 so there is some room for cuts.
Interestingly, some of the biggest names in storage cards (Samsung, Lexar, Kingston) have yet to release products with a capacity greater than 1TB.
A microSD card is still the smallest removable storage medium; With dimensions of 15 x 11 x 1 mm and a weight of 0.25 g, you can easily fit 500 AGI Supreme Pro TF138 in a small case barely larger than a standard 3.5-inch hard drive and weighing less than the iPhone 15.
Small enough to fit in the palm of your hand; 500 of these cards will offer a total capacity of one petabyte at a cost of approximately $100,000; Yes, it was a purely academic exercise, but it shows the potential of the world's densest storage media.
I contacted AGI for a review sample and will let you know as soon as I get a test product.
