Lenovo UltraBay

From Wikipedia, the free encyclopedia

UltraBay is Lenovo's name for the swappable drive bay in the ThinkPad range of laptop computers and some of IdeaPad Y Series laptops. Introduced with the ThinkPad 750 series,[when?] this technology has gone through redesigns with almost every new generation of ThinkPad, leading to some confusion. The following table gives an overview of the different UltraBay types, in which models they occurred and which drives are available for them. Note that the optical drive bay in G series and R40e series ThinkPads is not an UltraBay in that the drives are fixed and not removable. It is however, mechanically, an Ultrabay 2000-device without the surrounding "caddy".

On the media side different UltraBays relate to the form factor of the drives they accept; for example, early A, T and X series models can accept UltraBay devices up to 12.5 mm thick, whereas current T and X series machines are limited to devices no more than 9.5 mm thick, with the exception of the T500 and T510.

The IdeaPad Y400 and Y500 laptops have an ultrabay slot which can be swapped for another hard drive, another fan or another Nvidia GT650M (or GT750M)[1] GPU which will work in SLI with the system's primary video card for increased graphics performance. Existing orders for the UltraBay Y500 DVD Burner (no built in optical drive) were cancelled in early June, 2013, likely for quality problems.[citation needed]
