# ashift=12: 2^12 = 4KiB sectors, for certain NVMe drives use 13 (8KiB)

3

# autotrim: TRIM for SSDs

4

# encryption=on: Defaults to aes-256-gcm (since 0.8.4)

5

# pbkdf2iters=700000: Double the default PBKDF2-SHA1(?) iterations, default is 350000

6

# dnodesize=auto: Is supposed to be used on systems running SAMBA with xattr=sa

7

# compression=on: Defaults to lz4 (when lz4_compress is enabled, see `zpool get feature@lz4_compress ${NAME}`)

8

# normalization=formD: Decomposed Unicode normalization, implies utf8only=on, so UTF-8 filenames only

9

# longname=on: Allows filenames up to 1023 bytes, default is off meaning 255 bytes (supported since 2.3.0)
