Presently, a 64 GBs iPad model is quiclky becoming the “new” 16 GBs iOS device storage model, as presently, 128, 256, 512 GBs and 1.0 and 2.0 TBs internal storage models exist.
New base model iPads come in ONLY 64 GBs and 256 GBs configurations.
While a “sufficent” internal data storage option, a 64 GBs storage iPad starts out with approx. 60 GBs.,after initial internal flash drive formatting.
Minus approx. 6-6.5 GBs for iOS/iPadOS leaves between 53-54 GBs.
Minus 3-6 GBs, for iOS/iPadOS system operational reserve, that MUST BE MAINTAINED AT ALL TIMES, to ensure/insure normal, expected operation of iOS/iPad OS, leaves approx. between 48-50 GBs of actual, usable data storage space.
If you feel iPad storage needs are very modest, you may be able to get by with a 64 GBs internal storage model iPad.
256 GBs storage iPad starts out with approx. 238.5GBs.,after initial internal flash drive formatting.
Minus approx. 6-6.5 GBs for iOS/iPadOS leaves 231.0 GBs.
Minus 3-6 GBs, for iOS/iPadOS system operational reserve, that MUST BE MAINTAINED AT ALL TIMES, to ensure/insure normal, expected operation of iOS/iPad OS, leaves approx. between 224-228 GBs of actual, usable data storage space.
If you want to futureproof this new iPad purchase and have it for another 8-10 years, purchase the largest internal data storage, available in current iPad models, that you can afford.
Best of Luck to You!
