The tiny SanDisk 1TB microSD cards are breaking speed records

An entire terabyte of data can now fit on a microSD card — and now data can be recorded as fast as 160MB per second. On Monday, February 25, Western Digital announced the 1TB SanDisk Extreme UHS-I microSDXC card during Mobile World Congress. While the new microSD is not the first to reach that 1TB capacity, the company says the new card is the fastest 1 TB UHS-1 microSD card yet. Micron also launched a 1TB card, joining Lexar’s 1 TB announced earlier this year.

The new SanDisk card can record with 90MB/S write speeds with up to 160MB/s read speeds. Western Digital says the card can transfer files with twice the speed of standard UHS-1 microSDs. That’s paired with 1TB of storage, designed to expand the memory of a smartphone or to manage large files in action cameras and drones. The card will also launch in a 512GB version.

“People trust SanDisk-brand cards to capture and preserve their world. Our goal is to deliver the best possible experience so consumers can share the content that’s important to them,” Brian Pridgeon, director of marketing for SanDisk-branded products for Western Digital, said in a press release.

Western Digital says the new speeds are made possible through the company’s own flash technology. For smartphone use, the card fits in an a2 specification for running apps.

As part of the Extreme line, the card is designed to withstand shock, extreme temperatures, moisture, and X-rays. SanDisk also has 400GB, 256GB, 128GB, 64GB, and 32GB sizes available in the same series, though cards lower than 128GB have slower speeds.

Micron also announced a 1TB card, the Micron c200 1 TB micro SDXC UHS-1. The read speeds aren’t quite as fast as the SanDisk at 100MB/s, but write speeds have a slight edge at 95MB/s and the card also meets A2 specifications for running apps. The microSD uses a 96-layer 3D quad-level cell NAND design. Micro calls it “cost effective” but hasn’t yet shared a list price for the new card.

The 1TB SanDisk Extreme UHS-I microSDXC card will launch in April. Pre-orders are available now for about $450, or $200 for the 512GB version.

I’d trade the Pixel 11 Pro’s temperature sensor for HiLight every single time

I don’t miss the Pixel’s temperature sensor. I need HiLight more

Electronics, Mobile Phone, Phone

During the recent Pixel 11 announcement, Google showcased its new HiLight feature. We had our initial skepticism about it, but what caught my eye more was the temperature sensor being replaced. This was a feature barely anyone remembers (or uses), though it was something unique to the Pixels at the time.

The hardware eventually became capable of measuring body temperature, and I can appreciate the engineering behind squeezing something like this into a smartphone's body. Even then, I rarely had a reason to reach for it in day-to-day use. While I wasn't immediately drawn to the concept behind its replacement, I don't mind making this trade at all.

I played around with the Pixel 11 Pro Fold. I think Google finally saw the right focus points

The Pixel Fold’s smallest upgrades make the biggest difference

Electronics, Phone, Mobile Phone

Google has a new foldable ready to hit the shelves, and it's quite a compelling package with some alarms going off. I spent some time with the phone earlier today, and after collecting my thoughts, I can’t quite figure out whether I should be excited about it or disregard it in favor of rivals like the Samsung Galaxy Z Fold 8 pair.

The conundrum is warranted. It’s a $1,899 phone after all, and that’s the base price. But based on my limited time with the phone, it comes out as an overwhelmingly more practical device, especially for buyers based in the US. But let’s set aside the comparisons for the latter part of the debate.

Samsung may be going in for the full iOS-esque Liquid Glass look in OneUI 9.5

Well, well, well, Samsung could very much adopt the full Liquid Glass look instead of the mild-baked version we see currently.

Samsung appears to be preparing a major visual overhaul for One UI, with early leaks suggesting One UI 9.5 could adopt a more glass-like design with shinier edges, transparency, and greater visual depth.

The reported changes surfaced shortly after Samsung began rolling out One UI 9 Beta 5 for the Galaxy S26 series. According to Android Central, tipster Fahad Ali shared leaked screenshots of the upcoming interface on X, offering an early look at Samsung's apparent design direction.
