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.

Computer Hardware, Electronics, Hardware

MediaTek’s next flagship processor is already trailing Qualcomm in an early CPU showdown. Geekbench 7 results put MediaTek’s MT6995, expected to launch as the Dimensity 9600 Pro, behind Qualcomm’s SM8975, which is tipped to become the Snapdragon 8 Elite Extreme Gen 6, in both single-core and multi-core performance.

The MediaTek chip scored 3,242 in single-core and 11,132 in multi-core testing. Qualcomm’s upcoming flagship reached 3,582 and 12,247, giving it roughly a 10% lead in both tests.

Apple just gave millions of older iPhone owners another year of free satellite safety features
Apple promised two free years of satellite access back in 2022, and four years later, it still hasn't actually started charging anyone for it.
iPhone SOS Feature

Usually, footnotes are all about burying bad news from a launch event, something that will hit people where it hurts. But Apple did the opposite with its recent launch. 

Buried in a footnote in this week's iPhone 18 Pro release is good news, specifically for old iPhone users: Apple just extended free access to its satellite-based safety features.

iOS 27 beta 2 update on iPhone

Apple spent plenty of time talking about its shiny new iPhone 18 Pro models this week, but you won't need to buy a new phone to get one of its biggest announcements. iOS 27 officially arrives on September 14, bringing Apple's long-awaited Siri overhaul to supported iPhones. Apple first showed off iOS 27 at WWDC in June, and the software has spent the past few months moving through developer and public betas. Now, the finished version is almost ready for everyone.

Plenty of smaller changes are scattered throughout iOS 27, but Siri AI definitely grabs all the attention. This isn't just Apple adding a few new commands to the existing assistant, either. Siri has been rebuilt to better understand what you're asking and, more importantly, handle multi-step requests.
