| write cache size = number |
Allowable values : decimal number of bytes
Default : 0 (disabled)
Allocates a write buffer of the specified size in which Samba accumulates data before a write to disk. This option can be used to ensure that each write has the optimal size for a given filesystem. It is typically used with RAID drives , which have a preferred write size, and with systems that have large memory and slow disks.
