Overview

The Lenovo 0B47326 Ultrabay Slim DVD-RW Drive is a SATA-based internal optical drive designed to fit the 9.5mm Ultrabay media bay found in select ThinkPad laptops, including the T440p, T540p, W540, and W541. It installs directly into the bay without external cables, giving the laptop full optical read and write capability in a form factor that maintains the machine's slim profile. The drive complies with DVD Forum and DVD-multi-recorder specifications, supporting an extensive list of disc formats: CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-RAM, and both DVD+R double layer and DVD-R dual layer media.

Built-in 0.5MB buffer underrun protection helps ensure reliable recording sessions by preventing disc errors when data flow from the system is momentarily interrupted. This makes the drive suitable for burning data backups, software archives, or video discs with confidence. For ThinkPad owners who need occasional optical disc access but do not want to carry a separate external drive, this Ultrabay module provides a clean, integrated solution — though it does require giving up the bay that could otherwise house a secondary battery or storage caddy.
