ADATA SD700 512GB Black Gen1 External Solid State Drive (SSD)

The ADATA SD700 512GB Black external solid state drive is purpose-built for users who need reliable, high-speed portable storage in demanding environments. Housed in a compact square shell measuring just 83.5 × 83.5 × 13.9 mm and weighing a mere 75 g (2.6 oz), it disappears into a jacket pocket while delivering serious protection and performance. Connecting via USB 3.2 Gen 1, the SD700 reaches sequential read speeds of up to 440 MB/s and sequential write speeds of up to 430 MB/s — a marked improvement over conventional portable hard drives that typically top out around 100 MB/s. This makes transferring large files such as high-resolution video or RAW photo libraries noticeably faster. Inside, the drive relies on 3D TLC NAND Flash, a stacked-cell technology that offers higher storage density, improved endurance, and better power efficiency compared to planar 2D NAND designs. The drive operates on DC 5V at 900 mA — power drawn directly from the USB port, so no external adapter is required. Durability is a headline feature. The SD700 carries an IEC IP68 rating, confirming it is completely dust-tight and can survive submersion in up to 1.5 m of water for 60 minutes. It has also been tested to MIL-STD-810G 516.6 shock resistance standards, providing confidence against accidental drops. Compatibility is broad: the drive works with Windows XP through 10, Mac OS X 10.6 or later, Linux Kernel 2.6 or later, and Android 5.0 or later, making it straightforward to share content across platforms. The operating temperature range is 5 °C to 50 °C (41 °F to 122 °F). In the box you will find the drive, a USB 3.2 Gen 1 cable, and a Quick Start Guide. ADATA backs the SD700 with a 3-year warranty.
