Mass Storage Flashcards
Mass Storage
Types of mass storage
Hard Drivers
Solid State Drives
Optical Media
Mass Storage
Regardless of OS - your systems sees mass storage as
Logical Block Address’s
LBAs
Mass Storage
There is a difference between decimal values and
IEC values
Mass Storage
Magnetic drives data storage
Spinning Platters
Mass Storage
How do spinning platters actually store data
via magnetism and read/write heads
Mass Storage
Har disk sizes
- 5
- 5
- 8
Mass Storage
What protocol is used to communicate with hard disk drives
Ataboy
Advanced Technology Attachment
Mass Storage
The dominant ATA is called
SATA
Serial ATA
Mass Storage
Archaic and the domain of old ATA is called
PATA
Parallel ATA
Mass Storage
Solid State drives (SSDs) store data using chips
There are no moving parts.
Mass Storage
Data is stored in
Blocks and pages.
Mass Storage
SSDs come in the following sizes
- 5
- 5
M.2
Mass Storage
A protocol that increases performance over SATA in SSDs
NeVerMindE
NVMe
Mass Storage
An ancient standard that still has great support
Small Computer Systems Interface (SCSI)
Mass Storage
This old SCSI technology is long gone
PATA
Mass Storage
SCSI lang is still
supported
Mass Storage
Modern SCSI standard
Serial Attached SCSI
–and–
iSCSI
Mass Storage
When a system boots its looking for a
bootable device
Mass Storage
It is important that the system looks for these boot devices
The correct ones
Mass Storage
Boot order is defined in
CMOS system setup
Mass Storage
Storage is organized into Logical Blocks
LBAs
Mass Storage
These describe capacity not organizational structure
Gigabytes
and
Gibibytes
Mass Storage
These are the organizational structure of SSDs but not all mass storage devices
Pages
Mass Storage
Command and connection standard for mass storage devices.
Advanced Technology Attachment (ATA)
Mass Storage
This uses a serial data transfer protocol.
SATA
Mass Storage
SATA
Data is transferred one bit at a time from the drive to the computer and
one bit at a time from the computer to the drive.
Mass Storage
SSD memory cells
Pages
Mass Storage
Magnetic drive storage units
Sectors
Mass Storage
Why is NVMe the fastest interface
Because it uses PCLe lanes
Mass Storage
Combined SCSI and SATA
Serial Attached SCSI (SAS)
Mass Storage
What language does SAS speak
SCSI command language
Mass Storage
Connector interface and a form factor.
M.2
Mass Storage
Uses SCSi commands over ethernet
iSCSI
Mass Storage
Not a boot device
UEFI
its a firmware interface
Mass Storage
USB drivers, optical drives and SSDs are valid boot devices but will only boot if
They contain a working, properly-created bootable drive image.
