American Fuzzy Loop

Baru saja membaca sebuah program pengecek keamanan bernama 'american fuzzy loop'
Fitur utamanya sebagai berikut:
American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road.

AFL ini pada beberapa setting akan banyak menggunakan akses baca/tulis ke harddrive. Jika menggunakan SSD, maka akan ada potensi umur SSD cepat berkurang. Solusinya menggunakan RAMDISK seperti dijelaskan di http://www.cipherdyne.org/blog/2014/12/ram-disks-and-saving-your-ssd-from-afl-fuzzing.html.
SSD yang kuat ditulis sampai mendekati 2 Petabytes
SSD bisa tahan ditulis sampai 750TB ~ 2 Petabyte, jadi sebenarnya kuat juga, menurut artikel ini http://techreport.com/review/27436/the-ssd-endurance-experiment-two-freaking-petabytes
