I'm more impressed he got trips, that's pretty amusing about the USB being as fast as an SSD. Technically SSD's are supposed to be based off SD card tech if I'm not mistaken, issue with a USB being based off the same tech is the USB speeds themselves vs a SSD can go significantly faster due to its connector (SATA or otherwise). Although I can see USB C being 'fast enough' instead.

SSDs indeed use more or less the same type of flash memory as USB sticks and SD cards, but the fundamental difference lies in how the controllers interface with that memory. While modern high-end USB memory sticks and SD cards are able to keep a sustained single write operation going at pretty high speeds, each write operation must be finalized with an update to the media's block allocation map, which is the point where the media experiences a form of throttling. Consequently this results in multiple small write operations - each of which need the same finalization procedure - bringing the performance of the stick/card to a complete crawl, with even read operations being blocked.

There's probably admin tools for that.

I wondered about this, but sometimes people say it cause the previous post they see is 999 so they post it, sometimes you get lucky as heck haha. I doubt they'd screw with the admin tools just to do it.

On big boards there's so many posts per hour that it's impossible to really predict this way, it's very much luck.
I remember people used to run scripts to be sure to get the big gets (6+ last digits identical) but I suppose such methods don't work anymore with captcha and other anti spam measures.

Pass users don't have CAPTCHA though.

As someone not that familiar with 4chan, what are trips?

When the post number ends with 3 of the same number. In this case 000. Theres also dubs and quads.
