Computer Storage Interfaces Overview

Study Notes

Advanced RISC Machine (ARM)

A popular processor architecture known for its energy efficiency and performance in mobile devices.

Reduced Instruction Set Computer (RISC)

A processor design that uses a simplified set of instructions, resulting in faster execution speeds.

Serial Advanced Technology Attachment (SATA)

A modern interface for connecting storage devices like hard drives and solid-state drives to the motherboard.
Provides fast data transfer rates.
Uses a single cable for both data and power.
Comes in different versions: SATA I, SATA II, and SATA III with increasing data transfer speeds.
- SATA I: 1.5 Gbps
- SATA II: 3 Gbps
- SATA III: 6 Gbps

Enhanced Integrated Drive Electronics (EIDE)

An older interface for connecting hard drives and other storage devices.
Uses a ribbon cable for data transfer.

Parallel Advanced Technology Attachment (PATA)

An older interface for connecting hard drives and optical drives using ribbon cables.

Zero Insertion Force (ZIF)

A type of connector used in computer components that allows for easy and secure connection with minimal force.

Land Grid Array (LGA)

A type of processor socket where the pins are located on the motherboard, and the processor has flat contact pads.

Pin Grid Array (PGA)

A type of processor socket where the pins are located on the processor, and the motherboard has holes for the pins to fit into.

Peripheral Component Interconnect Express (PCIe)

High-speed interface used for connecting peripherals like graphics cards, network cards, and storage devices.

Small Outline Dual Inline Memory Module (SODIMM)

A type of memory module used in laptops and other small form factor computers.

Dual Inline Memory Module (DIMM)

A type of memory module used in desktops and servers.

Unbuffered Dual Inline Memory Module (UDIMM)

A type of DIMM that doesn’t require a buffer to manage memory signals, typically used in consumer-grade PCs.

Digital Visual Interface (DVI)

A digital video interface used for connecting monitors to video cards.

Video Graphics Array (VGA)

An older analog video interface used for connecting monitors to video cards.

Small Computer System Interface (SCSI)

A high-performance interface for connecting storage devices and peripherals.

High-Definition Multimedia Interface (HDMI)

A modern digital video interface for transferring audio and video signals.

Universal Serial Bus (USB)

A versatile interface for connecting a wide range of peripherals like keyboards, mice, printers, and external drives.

Non-Volatile Memory Express (NVMe)

A high-speed communication protocol designed for solid-state drives.
Offers much faster performance compared to SATA interfaces.

Redundant Array of Independent Disks (RAID)

A technology that combines multiple hard drives into a single logical unit to improve storage performance, reliability, and data redundancy.

RAM (Random Access Memory)

Temporary storage for actively used programs and data.
Allows for quick read and write operations making programs run smoothly.

ROM (Read-Only Memory)

Stores firmware or software that doesn't change frequently.
Its contents usually cannot be modified by a standard user.

HDD (Hard Disk Drive)

Traditional storage device using spinning disks to store data.
Offers high storage capacity at a lower cost compared to SSDs.
Relatively slow data access speeds compared to SSDs.

SSD (Solid-State Drive)

Fast storage device using flash memory.
No moving parts, making it more durable and resistant to shock.
Offers significantly faster read and write speeds compared to HDDs.

Wear Leveling

Technique used in SSDs to distribute write and erase operations evenly across memory blocks.
Extends the lifespan of the SSD.
Improves the overall reliability of the drive.

PSU (Power Supply Unit)

Converts AC power from the wall to DC power for computer components.
Capacity measured in watts (W).
Plays a crucial role in powering the motherboard, CPU, GPU, and other components.

ATX (Advanced Technology Extended)

A widely used standard for motherboard and PSU form factors in desktop computers.
Supports a variety of expansion slots, making it suitable for users with various needs.

ITX (Information Technology Extended)

A smaller motherboard form factor used in compact builds like mini PCs.
Provides limitations in terms of expansion possibilities compared to ATX.

20-Pin vs 24-Pin ATX Connector

Connect the power supply unit to the motherboard.
20-pin connectors are older and support fewer components.
24-pin connectors provide additional power for modern motherboards.
