+**In-memory Disk Accelerator**:
+
+Depot runners reserve a portion of the memory on the runner host for a disk accelerator, backed by a RAM disk. The accelerator acts as buffer between reading and writing to the root disk, which allows Actions runs to perform incredibly fast I/O operations much quicker than the physical disk would allow.

 ## Intel runners
 
 Intel runners use AMD EC2 instances. Their EBS volume is provisioned with 8000 IOPS and 250 MB/s throughput.
