A Low Level Format (LLF) means redefining physical disk layout. This is not doable by user on today's HDDs and SSDs. One usually want's to perform LLF to securely erase all data, reallocate bad sectors and/or remove malware.

---

[ATA Secure Erase][1]

Allows you to erase data on disk even on reallocated sectors. See:

• How do I perform a low level format of a Sandforce solid state disk?

# Ruby-level LOB fetch performance test
#
# Measures Ruby execution time for the same operations as bench_lob_fetch.c
# Tests 10,000 rows with 10KB LOBs using three different fetch modes:
#   1. LONG interface (:long_as_string) - default, fast
#   2. LOB locators without prefetch (:locator) - slow
#   3. LOB locators with prefetch (:locator + lob_prefetch_size) - slower
