The '''Memory Stick PRO Duo (MSPD)''' quickly replaced the Memory Stick Duo due to the Duo's size limitation of 128&nbsp;MB and slow transfer speed. Memory Stick PRO Duos are available in all the same variants as the larger Memory Stick PRO, with and without High Speed mode, and with and without MagicGate support.

Sony has released different versions of Memory Stick PRO Duo. A Memory Stick PRO Duo with MagicGate was released as a 512&nbsp;MB stick.{{Citation needed|reason=Existing citation link no longer valid|date=February 2020}} Additionally, a 16&nbsp;GB version in March 2008 and another a 32&nbsp;GB version on August 21, 2009.<ref>{{cite web|url=http://www.crunchgear.com/2009/08/21/sony-bumps-the-memory-stick-pro-duo-capacity-up-to-32gb/ |title=Crunchgear.com |website=Crunchgear.com |date=August 21, 2009 |access-date=November 13, 2011}}</ref> In 2009, Sony and SanDisk also announced the joint development of an expanded Memory Stick PRO format tentatively named "Memory Stick PRO Format for Extended High Capacity".<ref name="techon">{{cite web|url=http://techon.nikkeibp.co.jp/english/NEWS_EN/20090108/163799/|title=SanDisk, Sony to Expand Memory Stick PRO, Memory Stick Micro Formats|publisher=Nikkei Business Publications|date=January 8, 2009|access-date=January 5, 2010}}</ref> Sony has since finalized the format and released its specification under the new name, ''Memory Stick XC'' (see below).<ref name="sonyinsider">{{cite web|url=http://www.sonyinsider.com/2009/08/05/sony-finalizes-backwards-compatible-memory-stick-xc-with-2tb-maximum-capacity/|title=Sony Finalizes Backwards Compatible Memory Stick XC With 2TB Maximum Capacity|last=MacManus|first=Christopher|date=August 5, 2009|website=Sonyinsider.com|access-date=January 5, 2010}}</ref>
