SanDisk has launched a new 512GB microSD Express card aimed at creators, adventurers, and gamers who need high-speed, durable storage in a compact format. It is priced at 1499 yuan on JD.com and $119.99 on Amazon.
SanDisk 512GB microSD Express Specifications
The card uses PCIe 3.1 NVMe technology to deliver read speeds of up to 880MB/s. The 512GB and 256GB models reach write speeds of up to 650MB/s with sustained write speeds of 210MB/s.
The 128GB model offers the same maximum read speed but writes at up to 480MB/s, with a sustained rate of 100MB/s. These speeds place it close to mainstream portable SSDs and far ahead of standard microSD UHS-I cards.
The card supports 5.3K and 4K video recording, high-resolution RAW photography, and slow-motion footage. It works with PCIe NVMe and is backward compatible with microSD UHS-I devices, covering Android smartphones, tablets, drones, action cameras, laptops, and handheld gaming consoles. It is also compatible with the Nintendo Switch 2.
The card is resistant to water, extreme temperatures, humidity, drops, shocks, magnetic interference, X-rays, and abrasion. SanDisk includes its ThermAdapt technology, which uses a specially designed shell and controller with dynamic thermal management to prevent overheating during heavy workloads.
When paired with the SanDisk Pro-Reader SD Express dual-slot card reader, the card reduces transfer times significantly. Transfers of a 60-minute 4K30 video can be up to 2.8 minutes faster, while 2,000 10MP RAW images move up to 2.9 minutes faster. Under optimal conditions, a two-hour HD movie transfers in less than 3.5 seconds
The card comes with a lifetime limited warranty and a two-year subscription to SanDisk’s RescuePro Deluxe file recovery service. It measures 14.99mm by 10.92mm by 1.02mm and operates in temperatures from -25°C to 85°C, with storage tolerance from -40°C to 85°C.
