  • Comes in two sizes; 50TB & 80TB

Snowball Edge

  • Is a 100TB data transfer device.

  • Snowball Edge has both storage and compute capabilities.

  • It supports specific Amazon EC2 instance types and AWS Lambda functions.

  • Secure as data is encrypted at rest and in transit.

  • Can be used as a temporary storage tier for large local datasets or support local workloads in remote offline locations.


Snow Mobile
