About this product
This Hitachi DK23AA-90 is a 9GB 2.5-inch hard disk drive with an ATA/66 interface. Operating at 4200 RPM with a 512KB cache, this HDD is compatible with both laptops and PCs. It features a shock sensor for enhanced durability and is part of the Travelstar product line. The drive is listed as used but fully tested and pulled from a working environment, making it a suitable choice for legacy systems or specific industrial applications requiring a smaller capacity, older interface drive.
Our take
If you're diving into retro builds or need a very specific replacement for an older laptop or PC, this 9GB Hitachi DK23AA-90 could be what you're looking for. The 4200 RPM speed and ATA/66 interface are definitely old school, so don't expect blazing performance. However, for a period-correct restoration or simple data storage where capacity isn't a huge concern, it serves its purpose. The integrated shock sensor is a nice touch for a portable drive of its age. As a used item, the "fully tested" assurance is good, but the 9GB capacity is restrictive for anything beyond very basic use.
