Abstract
A storage device. The device includes both low-latency persistent memory and higher-latency nonvolatile memory. The persistent memory may be used for write caching or for journaling. A B-tree may be used to maintain an index of write requests temporarily stored in the persistent memory. Garbage collection may be performed in the nonvolatile memory while write requests are being stored in the persistent memory.
