- -C

- -B

- -U UUID

- -b bucket-size
- Specifies the bucket size. Allocation is done in terms of buckets, and
cache hits are counted per bucket; thus a smaller bucket size will give
better cache utilization, but poorer write performance. The bucket size is
intended to be equal to the size of your SSD's erase blocks, which seems
to be 128k-512k for most SSDs. Must be a power of two; accepts human
readable units. Defaults to 128k.
