Accelsior 1M2 Keep Your Cool

Keep Your Cool, Silently

When deadlines and workload pressures start to mount, the Accelsior 1M2 helps you keep your cool. An industrial quality black aluminum alloy heat sink with deeply grooved fins keeps the Accelsior 1M2 performing silently so you can stay chill and focused in even the most challenging environments.

The Performance Advantage Of Nvme

Non-Volatile Memory Express (NVMe) is a communication standard specifically built to optimize the performance of modern flash technology. Using it enables the Accelsior 1M2 to deliver significantly faster SSD performance than an SSD that’s still using the old SATA interface — a communication protocol that was originally designed for hard disk drives. Instead of tinkering around with slow-performing SSDs, you can shift your workflow into the fast lane with Accelsior 1M2.
