The DJSA-232 is one of IBM’s most marvellous creations: a four-platter 2.5″ drive, with a height of only 12.5mm. Truly incredible stuff, particularly given the time in which this drive was produced. In 2023, this drive is still an incredible innovation for the hard drive industry, stuffing as many platters as possible in such a low-height form-factor.<\/p>\n

While IBM had major trouble with their drive designs at the time, this unit fortunately lives on today. It’s unknown as to how unreliable these similarly produced Travelstars are compared to their infamous “Deathstar” brethren, but at least they’re not all in a landfill just yet.<\/p>\n

The DJSA-232 is one of many Travelstar’s from the period, obviously being one of the higher end options IBM produced. Limits were pushed, which was perhaps something that was too audacious when regarding their 3.5″ line-ups (see: 75GXP<\/a>).<\/p>\n

The label.<\/strong><\/em><\/figcaption><\/figure>\n
Being well into IBM’s glory years when concerning their label designs, this unit delivers the usual excellent information motherload.<\/p>\n
This unit was produced in December 2000, in IBM’s drive factory in Thailand.<\/p>\n

The rear.<\/strong><\/em><\/figcaption><\/figure>\n
This drive really is packed. With the platter count totalled above, it really is impressive how thin IBM managed to make these models.<\/p>\n

The base.<\/strong><\/em><\/figcaption><\/figure>\n
The base has little going on, the usual elements stand out.<\/p>\n

The PCB.<\/strong><\/em><\/figcaption><\/figure>\n
There are few IC’s on the back of this board, including 2MB of buffer memory from OKI, a standard Mitsubishi microcontroller (as seen on IBM’s 3.5″ desktop drives, albeit somewhat different models) & a spindle motor controller from Texas Instruments.<\/p>\n
It’s unknown what Asuka-5B refers to, given the often obfuscated nature of IBM’s native codenames.<\/p>\n

PCB rear.<\/strong><\/em><\/figcaption><\/figure>\n
There’s nothing of note on the rear, aside from the indication that the assembly was produced in the Philippines, with the PCB itself being made in Japan.<\/p>\n

Performance metrics.<\/strong><\/em><\/figcaption><\/figure>\n

An example machine – Ref: Maximum PC, December 2000 [1]<\/strong><\/em><\/figcaption><\/figure>Given the clear label indications that this example came from a Dell machine originally, it is quite possible it served in the exact model above: the Inspiron i8000. Obviously, for the year 2000, 32GB was certainly quite a capacity for a 2.5″ drive. As a result, these drives found use in higher-end machines, with the machine listed above being catered towards multimedia use with a price-tag of near $3.6k USD.<\/p>\n
Even now, almost 25 years later, the DJSA-232 is an incredible feat of technology. IBM pushed the barrier as hard as possible, it’s just a shame they departed so soon after.<\/p>\n
