The DTNA-22110 is a fairly unassuming drive from IBM, having been released in 1996. It’s a 2.1GB 2.5″ unit, for mass mobile computing during a period where things began to be somewhat more attainable for the general population. While basic, IBM’s 2.5″ drives from the period have their own stories to tell.

It’s a reasonably low profile drive for the period (as 4LP would suggest), being only 12.5mm in height with three platters. This form factor for the platter count was fairly widespread at the time, with Toshiba having managed it back with the MK1926FCV in 1995 as an example.
This drive was produced in Thailand, prior to that of IBM owning their own factory. This particular unit was manufactured in April 1997.
It’s an excellent label, featuring jumper settings & most practically useful information.
It’s of similar design to previous Travelstars, with a few changes here and there.
It’s the base of the board! Aside from some foam, it’s blank.
Logic is from Mitsubishi, TI and custom IBM IC’s. As is with many IBM’s of the era, the codename printed on the board of “AYABE-5” is of unknown relevance. Who knows if that’s the internal name for these units.
The rear of the board is nothing special, a few stickers & date codes here and there.
It’s a fairly basic 2.5″ drive for 1997. Even simple drives need their time in the spotlight, right?
