What USB flash drive format and capacity do you need to save your DVD collections?
The capacity of the USB flash drive you need to store your DVD collection depends on the size of each movie. A standard single-layer DVD can hold up to 4.7 GB, while a dual-layer DVD can store up to 8.5 GB.
If we assume that most movies are around 2 hours long and encoded with good quality at about 1-2GB per movie, a 128GB USB flash drive could hold approximately between 64 and 128 movies. However, this is an estimate; actual storage may vary based upon the specific file sizes.
As for format, it depends on what device you plan on using to play these files:
FAT32: This is compatible with almost all systems but has a file size limit of only 4GB.
NTFS: Works well with Windows systems and supports large files but might not work perfectly with other operating systems like macOS without additional software.
exFAT: This works well across both Windows and macOS systems and supports large files as well.
So if you're planning on storing full DVDs (as ISOs or Video_TS folders) which are larger than 4GB in size, then choosing NTFS or exFAT would be better options than FAT32.
