Adata advertises sequential learn speeds of as much as 3.8GB/s and write speeds reaching 3.7GB/s with its new SE920 transportable SSD. When linked to gadgets that may saturate its USB4 bandwidth, that efficiency may nearly double the Elite SE880 the corporate launched final 12 months and practically quadruple main fashions like Samsung’s T7 Defend.
Unsurprisingly, the SE920 is backward appropriate with USB 3.2 and a couple of.0, however its USB-C USB4 connection additionally permits cross-compatibility with Thunderbolt 4. Sequential write speeds by Intel’s associated switch protocol can attain 3.2GB/s. The SSD is available in 1 and 2TB fashions.
One other distinctive characteristic is the drive’s spring-loaded transformable shell, which controls its lively cooling system.
