Buying Guide

Choose the right form factor

Match drive type to your system: M.2 2280 for NVMe slots, 2.5" for laptop bays, and 3.5" for desktop drives or trays

Prefer interface over claimed speed

PCIe Gen3/4 NVMe offers much higher throughput than SATA; pick NVMe for OS or application installs when the motherboard supports it

Weigh capacity vs longevity

SSDs deliver faster access and durability for OS use, while HDDs remain cost-effective for bulk storage and archival data

Check power and cooling needs

High-speed NVMe drives and 7200 RPM HDDs benefit from airflow or heatsinks to sustain performance under load

Consider installation accessories

Adapters, riser cables, or hot-swap trays can enable compatibility and easier maintenance in desktops and servers

Verify warranty and controller type

Controller, NAND type, and manufacturer warranty give signals about long-term reliability and performance consistency
