| .BR \-b\ \fIbucket-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. |
