Amazon has started selling the 1TB version of the Sandisk Extreme , which was announced earlier this year, and means you can potentially load your smartphone or camera with more storage space than your laptop.

It is temporarily out of stock, having moved out of preorder earlier today, which indicates that there might be a backlog in orders.

At $450 (around £350, AU$650) on Sandisk’s online shop , it carries a significant premium over smaller capacities. The 128GB version for example retails just over $26 (around £20, AU$40), less than half the per GB price.

The card (known as the SDSQXA1-1T00-GN6MA) comes with a lifetime warranty and, Sandisk says, is waterproof, shockproof and x-ray proof. With a read speed of up to 90MBps, the Sandisk Extreme is compatible with the new V30 speed class and can record videos at 4K without hitch.

More coming but where’s Samsung?

Should you want something even faster, then try the Extreme Pro , also in 1TB capacity. It went on sale at Amazon today albeit only in the UK and at a much higher price as well. It almost doubles the read speeds to 170MBps and is fast enough to record in 8K.

Micron and Lexar are the other manufacturers that have already announced a 1TB microSD card; the first one, which we understand, will start selling its card before the end of the month.

Other major players that are currently selling 512GB microSD cards include Samsung, Kingston, PNY and Integral. None have confirmed yet when they will offer a 1TB version.
