Solid-state drives don't have moving parts, and that simple fact makes them intrinsically suited for use as portable storage. Adata's SD700 external SSD combines the inherent robustness of SSDs with a dust-proof and water-resistant case to create a tough and tiny take-along drive.
Adata says the SD700 been tested for compliance to the IEC's IP68 protection standard. That means it should be impervious to dust and waterproof for up to an hour in 5' (1.5 m) of water. The company also claims the drive passes muster for the US Army's 810G-516.6 shock and drop resistance standard. The SD700's performance in those tests is no doubt improved by the shock-absorbing rubber that encircles its outer edge. Despite the durable design, Adata says the new drive masses just 3.5 oz (100 g).
The SD700 hooks up to PCs using USB 3.1 Gen 1, better known as USB 3.0. Adata says the drive can push 440MB/s either way across its USB cable. The SD700 will come in 256GB, 512GB, and 1TB capacities when it becomes available online—although Adata didn't clarify when that might be. The company expects the 256GB model to go for $110, while the 512GB model should sell for $190.
