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 Logical Disk Manager (LDM) is an implementation of a logical volume manager for Microsoft Windows NT, developed by Microsoft and Veritas Software. It was introduced with the Windows 2000 operating system, and is supported in Windows XP , Windows Server 2003 , Windows Vista , Windows 7 , Windows 8 , Windows 10 and Windows 11 .
C: — First hard disk drive partition. D: to Z: — Other disk partitions get labeled here. Windows assigns the next free drive letter to the next drive it encounters while enumerating the disk drives on the system. Drives can be partitioned, thereby creating more drive letters. This applies to MS-DOS, as well as all Windows operating systems.

In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface.
Higher-level logic than RAID1 and RAID5 - multiple storage spaces span multiple disks of different size, storage spaces are resilient from physical failure with either mirroring (at least 2 disks) or striped parity (at least 3 disks), disk management and data recovery is fully automatic Windows 10: Storage Spaces: Yes Yes Yes Yes Yes Yes Yes
Note that many of these protocols might be supported, in part or in whole, by software layers below the file manager, rather than by the file manager itself; for example, the macOS Finder doesn't implement those protocols, and the Windows Explorer doesn't implement most of them, they just make ordinary file system calls to access remote files ...
