A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
The FAT file system is a file system used on MS-DOS and Windows 9x family of operating systems. [3] It continues to be used on mobile devices and embedded systems, and thus is a well-suited file system for data exchange between computers and devices of almost any type and age from 1981 through to the present.

The exFAT format allows individual files larger than 4 GB, facilitating long continuous recording of HD video, which can exceed the 4 GB limit in less than an hour. Current digital cameras using FAT32 will break the video files into multiple segments of approximately 2 or 4 GB. EFS supported in Windows 10 v1607 and Windows Server 2016 or later.

File Allocation Table (FAT) is a file system developed for personal computers and was the default filesystem for the MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.
The text is in an alphanumerical symbolic raw content format. A recording format is a format for encoding data for storage on a storage medium. The format can be container information such as sectors on a disk, or user/audience information such as analog stereo audio. Multiple levels of encoding may be achieved in one format.
P2 (P2 is a short form for "Professional Plug-In") is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004.
