Tough USB flash drives for secure industrial use
Furthermore, a version with MLC-NAND in pSLC configuration is offered under the name U-56k for an endurance seven times longer than that of a MLC-NAND with the same memory density. SLC versions with densities of 2 to 32 GB, MLC versions with 16 to 128 GB and a pSLC configuration with 8 to 64 GB will be available by the end of the year. All USB 3.1 sticks are also offered in versions with integrated data protection features. In combination with the SuperSpeed USB 3.1 interface, U-500k, U-50k and U 56k offer outstanding data rates for the sequential writing of data. As the firmware works with page-based mapping, the random-write IOPS performance increases, while wear decreases significantly. This in turn makes USB sticks the perfect solution for data logging applications. Smart firmware routines recognize weak data segments and update them before any data loss occurs. This is particularly important when used as boot medium or for long-term data storage.
