Integration of a near full-length strip of thermal tape between the WD Blue SN550E drive and the front cover aids in maintaining cool operation.

The company opted for an ASMedia ASM2362 USB 3.2 Gen 2 to PCIe 3.0 x2 bridge chip in the design, similar to the company’s WD My Passport SSD. This makes for a small and compact design that is also pretty light, but a little less resistant to twists and bending. But unlike the Extreme Pro, the Extreme v2’s case and internal structure is made of plastic rather than rigid aluminum. With a carabiner loop integrated and a durable silicone coating, the Extreme v2 features a functional, portable, and enduring design for those on the move in tough conditions. SanDisk’s Extreme v2 is a bit bigger than the original, measuring 101 x 52 x 9 mm and weighing in at under 63 grams. On top of this, SanDisk backs the Extreme v2 with a longer five-year warranty over its predecessor’s three-year warranty. The Extreme v2 has been tested to withstand water flow at a rate of 30kPa for three minutes, and dust contact does not interfere with operation.

SanDisk’s Extreme v2 comes with an IP55 rating, AES 256-bit hardware encryption support, and a long warranty to ease concerns when traveling with your storage. However, while not bus saturating, sustained performance will remain reasonable with the 1TB and 2TB models. The smallest capacity will suffer the most.

Due to a small static SLC cache, the Extreme v2 will degrade to direct-to-TLC speeds quickly. Rated for up to 1,050/1,000 MBps read/write, the SanDisk Extreme v2 can deliver some very responsive performance, but these are peak figures. SanDisk’s Extreme v2 comes in capacities of 500GB, 1TB, 2TB, and 4TB, with prices ranging from $0.15-$0.19 per GB. 'IP55 water-dust resistant 2-meter drop protection'
