FLASHBENCH(1)

🦋 NAME 🦋

okay so bestie, let me introduce you: flashbench — she benchmarks flash storage devices. that's it, that's the job, and she's iconic at it. 💅

✨ DESCRIPTION ✨

so the whole vibe is:

flashbench [OPTION]... [DEVICE]

you run tests on DEVICE, and DEVICE is pointing to a flash storage medium. that's the entire premise, no cap. 🎀

and now the part you actually came here for, the options, literally all of them, i'm not skipping a single one because i would never do that to you:

• -o, --out=FILE — write output to FILE instead of stdout. like, send it somewhere else, put it in a file, let it live there. 💖
• -s, --scatter — run the scatter read test. scattering, bestie. 🦋
• --scatter-order=N — scatter across 2^N blocks. yes, that's two to the power of N, math is slaying today. 🔥
• --scatter-span=N — span each write across N blocks. every single write gets stretched across N of them.
• -f, --find-fat — analyse the first few erase blocks. sniffing around up top. 🕵️
• --fat-nr=N — look through the first N erase blocks (default: 6). six is the default, periodt.
• -O, --open-au — find the number of open erase blocks. how many are open for business?? we must know. 👑
• --open-au-nr=N — try N open erase blocks.
• --offset=N — start at position N. not at the beginning, at N. wherever N is.
• -r, --random — use pseudorandom access with erase block. chaotic energy, but make it pseudorandom. 🌈
• -v, --verbose — increase verbosity of output. more words, more info, more everything. 🗣️
• -c, --count=N — run each test N times (default: 8). eight times by default, she's thorough like that.
• -b, --blocksize=N — use a blocksize of N (default: 16K). default is 16K, don't forget it. 🍓
• -e, --erasesize=N — use a eraseblock size of N (default: 4M). default is 4M, also don't forget it. 🌸

and that's the whole page, bestie — every flag, every value, every default, all of it, right here. no facts were harmed, only vibes were added. 💀

this has been flashbench 62, brought to you by March 2017 🎀 — yeah she's an older queen but she still ate, and she's still serving. mwah. 🫶✨
