Disk Types:

IDE -- ATA --PATA , SATA
IDE - Integrated drive/device Electronic
ATA - Advance Technology Attachment
PATA - Parallel ATA
-40 pin data connector
-ribbon cable
-one side of cable goto MB , other side 2 connector for a device each
-one cable you can connect 2 devices/drive
-data transmission speed
-read / write speed
-old and not using now a day

SATA - Serial ATA
-7pin data connector
-one cable for one device
-faster than PATA
-data transmission speed
-read / write speed
-still we are using

SATA III - 6Gbps

-----------
SCSI - Small Computer System Interface

-interface to system , connected to motherboard
-we can connect different/multiple type of devices
-multiple device
-Devices: SCSI - Harddisk, CDROM, Printer and Scanners
-Hot Swappable
-enterprise solution

Cold Swap: to connect or disconnect a device to system ,
we need to turn off the system

-all internal device
-internal harddisk,cdrom,dvd
-ram ,cpu

Hot Swap: to connect or disconnect a device to system, no need to turn off the system
-we can connect or disconnect device while system is running

USB device, pendrives, mouse, keyboard , extranel harddisk ,priters scanners
-------------

iSCSI - Internet SCSI
-iSCSI not connect to any system / motherboard
-itself a storage bay , a storage box
-it has NIC (network interface card)
-we connect through network
-------------
SSD - Solid State Drive
NON VOLATILE STORAGE
-NAND type
-No loose parts
-light weight
-small size
-faster than SATA
-LESS POWER CONSUMES
-Costlyer than SATA
NAND SSD SATA
-Read and Write speeds up to 540MB/s and 500MB/s respectively

NAND SSD NVMe M.2
-3600MB/s R, 2000MB/s W
-------------

DAT - Digital Audio Tape
or
DDS - Digital Data Storage
