FAT32

has 8 hexadecimal character instead of 4 like 16. Very old. Could support 8 TiB volumes.

Fragmentation

When a file is in two different spaces on the file allocation table.

NTFS stands for what?

New Technology File System(NTFS). Been around for a long time. dominant today. Supports up to 16 EiB volumes. Individual files can be up to 256 TiB. Primary for windows

MFT stands for what?

Master File Table, used with NTFS. Sits in the middle of your volumes.

ExFAT

The inbetween FAT32 and NTFS. Less overhead. Great for thumb drives.

CDFS stands for what?

Compact Disc File System. Standard for all optical media. And have files up to 4 GiB.

ext3 for Linux

Supports 32 TiB volumes, and files are up to 2 GiB. Are for Linux

ext4 for Linux

Supports up to 4 EiB volumes, and files up to 16 TiB. Are for Linux

HFS+ stands for what?

Hierarchical File System Plus for Mac OS. Dominant for Mac OS and supports 8 EiB volumes and files.

Disk Management

Windows uses disk management to partition and format disks.

Dynamic Disks

Unique to Windows. You can shrink and expand and span across multiple drives.

Spanned volume

you can take two disks to act like one. Not good to do.

GPT advice

1. Keep boot drive basic (not dynamic). 2. Set boot drive to GPT. 3. Easy to create dynamic disks.

Software RAID

Uses the operating system to configure the RAID array.

Storage Spaces

A powerful tool to configure advanced software RAID arrays. And also provides great flexibility.

Types of encryption

File based encryption and disk-based encryption.

File-based encryption

encrypting files and folders

Disk-based encryption

encrypting an entire drive.

EFS stands for what?

Encrypting File System(EFS). Used in windows and built into NTFS. Allows you to encrypt files and folders

TPM stands for what?

Trusted Platform Module. A chip built into the motherboard with a encrypted key.

Bit Locker

a disk-based encryption used on windows. Requires TPM.

Storage Spaces

software RAID tool built into windows OS.
