Thick Provision Lazy Zeroed vs Thick Provision Eager Zeroed

Thick Provision Lazy Zeroed: Consumes the allocated disk space on creation time, although data remaining on the disk is not wiped, rather it is zeroed out on demand later. Hence old data could theoretically be retrieved.

Thick Provision Eager Zeroed: Consumes the allocated disk space on creation time, although in contrast to the Lazy Zeroed approach remaining data on the disk is zeroed out. This option is best for performance, although takes much longer to initially create the disk.
