DRAM (Dynamic Random Access Memory)
DRAM is a type of RAM that requires continuous refreshing of its capacitors, unlike static RAM (SRAM). It loses stored data when the computer is turned off.
SDRAM (Synchronous DRAM)
SDRAM syncs with the CPU’s clock speed, allowing faster performance. It comes in 168-pin DIMMs for desktops/servers and 144-pin SoDIMMs for laptops.
DDR RAM (Double Data Rate)
Doubles data transfer by utilizing both edges of the clock cycle. It comes in 184-pin DIMMs for desktops/servers and 200-pin SoDIMMs for laptops.
DDR2 (Double Data Rate Gen 2)
Further increases speed and introduces dual-channel mode. It uses 240-pin DIMMs for desktops/servers and 200-pin SoDIMMs for laptops.
DDR3 (Double Data Rate Gen 3)
Improves transfer speeds and reduces power consumption by 30%. It comes in 240-pin DIMMs for desktops/servers and 204-pin SoDIMMs for laptops.
DDR4 (Double Data Rate Gen 4)
Boosts transfer speeds up to 4266 MT/s and lowers voltage to 1.2V. It uses 288-pin DIMMs for desktops/servers and 256-pin SoDIMMs for laptops.
DDR5 (Double Data Rate Gen5)
Offering a substantial boost in data transfer speeds, reaching up to 8400MT/s, it operates at a lower voltage of 1.1V, increasing energy efficiency. DDR5 modules are available in 288-pin DIMMs for desktops and servers, and 262-pin SoDIMM variants for laptops. It also supports larger capacities and includes on-die ECC (Error Correction Code) to improve reliability and data integrity, making it ideal for high-performance applications like gaming, data centers, and AI.
mSATA SSD
A compact version of SATA SSDs, used primarily in ultra-portable devices and older laptops.
M.2 SSD
A versatile SSD available in both SATA and NVMe protocols, popular for its small form factor and high performance in laptops and desktops.
U.2 SSD
A high-performance SSD that connects via the PCIe interface, commonly used in enterprise environments, providing high capacity and speed.
SSD
(Solid-State Drive)
SSD is a storage device that uses NAND flash memory to store data, unlike traditional hard drives (HDDs) that rely on spinning disks. SSDs have no moving parts, making them faster, more durable, and energy-efficient. They offer quicker data access, reduced load times, and improved overall system performance. SSDs are commonly used in laptops, desktops, and servers, providing a reliable and high-speed alternative to HDDs for storing and retrieving data
SATA SSD
(Serial ATA SSD)
A type of SSD that connects via the SATA interface, offering read/write speeds up to 600 MB/s. It is widely used in consumer devices but is slower than newer interfaces like NVMe.
NVMe
(Non-Volatile Memory Express)
This is a high-performance protocol designed for accessing non-volatile storage, such as SSDs, through the PCIe (Peripheral Component Interconnect Express) interface. NVMe enables faster data transfer speeds, lower latency, and improved efficiency compared to older storage protocols like SATA and AHCI. It is optimized for modern SSDs, allowing for parallel processing and faster access to data, making it ideal for tasks requiring high-speed performance, such as gaming, data-intensive applications, and enterprise storage solutions.
3DS Memory
(Three-Dimensional Stacked DRAM)
This is a type of DRAM that stacks multiple layers of memory dies vertically to increase capacity and performance without expanding the module's footprint. Using Through-Silicon Vias (TSVs), these layers are interconnected, improving bandwidth and power efficiency.
