3.5″ Floppy disk drive benchmarking (WHL #57)

Yeah, you read that right. Time for some serious benchmarking of good old floppy drives. The type of benchmark that the interwebs have been waiting for.

In case you’re questioning my mental health right now: Nope, not affected by COVID-19 or the “quarantine” (that only keeps me from delivering a 2U server and causes people to act strange in the supermarkets). I’ve gone mad quite a long time ago. Probably a glitch during assembly.

Now, I got four bad boys here, revving their, umm, stepper drives?
Alps Electric DF354H(121G), 33wk 2007 – full size 3.5″ drive (5V 1000mA)
IBM FRU 06P5223 ASM 08K9835, Feb 2004, USB drive (5V 500mA)
Sony MPF820, Dec 2005, Slim drive (5V 750mA)
Teac FD-05HF, May (?) […]

Chart of Electromagnetic Radiations – vectorized (#P5F1)

News from the insane vectorizing bloke – the next part of the HUGE poster (see #P5 if you have no clue what I’m talking about) is sort-of ready. It’s the block on the lower left corner, describing reflection, refraction, diffraction, interference, polarization and Doppler’s principle.

Demo PNG is below (click for 8.2 MP rendering), SVG download link at the end of the page.

Lessons learned:

  • I’m at 21% of the image area now (wohoo!), but that was probably the easiest 21%. Yet, with the steep learning curve, it’ll stay at roughly 1-2 hours of clickedidoo per percent of area.

Chart of Electromagnetic Radiations – vectorized (#P5)

Hey – I never met you and this is crazy…but here’s my first piece, so help me maybe? (umm, I had to look this up, for sure)

When watching good ol’ Dave’s mailbags, number 940 to be precise (starting at the 9 minute mark), I was instantly hooked when he showed the gorgeous physics poster. Being a qualified physics nerd myself and obviously having too much free time, I had the idea of…vectorizing it. For the greater good, in that case, nerdgasms in posters beyond A0 size. (is there a format beyond ANSI F for you weird yankee letter format guys?) […]
