Last June, the SD Association announced SD Express, an incredibly fast SD card standard that taps a PC's PCI Express bus for speeds up to 985 Mbytes/s. Virtually no one adopted it. Now, the SD Association has tried again, applying the same spec to the much more popular microSD card form factor: microSD Express. On paper, the SD Express standard should have succeeded. With support for both the PCI Express bus as well as the NVMe memory access layer, SD Express cards could have provided external removable storage about as fast as an internal SSD--great news for laptops.
Samsung has kicked off mass production of its new super-fast 512GB eUFS 3.0 chips and says it will launch 1TB versions later this year. The chip will be the industry's first 512GB embedded Universal Flash Storage (eUFS) 3.0 for mobile devices, which is twice as fast as eUFS 2.1. Samsung debuted its 512GB eUFS storage chips in 2017, which offered double the capacity of its 2016 eUFS, and quadruple the capacity of its first eUFS 2.0 chips in 2015. The key difference with the 512GB eUFS 3.0 chip is the speed enhancement, offering a sequential read rate of 2,100 megabytes per second (MB/s), or double what was available with eUFS 2.1. According to Samsung, the 512GB eUFS 3.0 storage chip is four times faster than a SATA solid-state drive and 20 times faster than most microSD cards.
Most people look to Amazon Prime Day for deals on big-ticket items -- think laptops, fancy headphones and the like. But the shopping event also brings a ton of sales on tech that you might not think about too often, like the portable drive you use to store family photos and SD cards for your camera or smartphone. These are gadgets that you'll want to get on sale if you can, because they can be expensive on a normal day -- plus, if you wait until you're in dire need of a new one, you may get stuck paying full price. Prime Day this year brought a number of good deals on SSDs, portable drives, microSD cards and other storage devices, and some of them represent rock-bottom prices. Here are the best storage deals we found for Prime Day.
The days of the lowly 2GB MicroSD card are officially over. On Tuesday, Samsung announced a 256GB MicroSD card, matching – or exceeding – the storage capacity of a typical new laptop. This is remarkable because MicroSD cards are some of the smallest memory devices on the planet-- even smaller than already-tiny MiniSD cards. Samsung's EVO Plus 256GB card is targeted at high-end devices that need lots of additional storage. That includes smartphones, tablets, and a variety of cameras, including 360-degree video cameras that require lots of capacity.
Western Digital has unveiled what it says is the world's highest-capacity microSD card -- one that crams 400GB of storage into your smartphone. The company says its 400GB SanDisk Ultra microSDXC UHS-I card is world's highest-capacity microSD card for use in mobile devices. The card can hold up to 40 hours of Full HD video and can transfer data at up to 100MBps: at that speed users could move 1,200 3.5MB photos per minute over USB 3.0. The card, which Western Digital is aiming at Android smartphone and tablet users, comes with a ten-year warranty and a US retail price of $249.99. Western Digital said its memory technology, design and production processes allowed for more bits per die, enabling it to push the microSD card capacity up again.
