Enhancing The Performance Of Small Writes - HP ProBook 4330s Installation Manual

Enhancing the performance of small writes

Performance degradation can occur on a Windows 7 or WinPE platform that performs many small
writes to an Advanced Format drive. For example, using the ImageX command-line tool to apply a
Windows image (.wim file) to an Advanced Format drive would take significantly longer than
applying the same image to a traditional hard drive.
