Apple today announced 128GB version of the fourth generation iPad, both Wi-Fi and Wi-Fi + Cellular models. It seems that not everyone's convinced that iPad with bigger space maybe useful for many iPad users. Sure, for casual users 32GB or 64GB models will suffice. But people using iPads professionally might have different needs. Here's what Apple says about that:
iPad continues to have a significant impact on business with virtually all of the Fortune 500 and over 85 percent of the Global 500 currently deploying or testing iPad. Companies regularly utilizing large amounts of data such as 3D CAD files, X-rays, film edits, music tracks, project blueprints, training videos and service manuals all benefit from having a greater choice of storage options for iPad. The over 10 million iWork® users, and customers who rely on other incredible apps like Global Apptitude for analyzing team film and creating digital playbooks, Auria for an incredible 48 track recording system, or AutoCAD for drafting architectural and engineering drawings, also benefit greatly from having the choice of an iPad with more storage capacity.
Just to go slightly deeper, Apple mentions Auria app which supports up to 48 mono tracks of 24bit/96kHz quality. Say, you are working on a 4 minute song, each 24bit/96kHz mono track would require 65.92MB of space. That means 48 auria track project would require a total of 48 x 65.92MB = 3.09GB space. Now that's almost 5% of total storage capacity of 64GB model iPad. That's a lot!
Audio file sizes are tiny compared to raw video files that video editors might have on their iPads. So yes, there's a need for 128GB iPad.
