Guide & know-how

NVMe SSD = up to 2000 MB/s, ideal for backups and 4K video edit. SATA SSD = 400–550 MB/s, cheaper than NVMe and plenty for standard backups. USB stick = practical for transfer and boot sticks, USB 3.2 models reach 300–400 MB/s. HDD only makes sense for cheap bulk storage 4–18 TB — backup NAS or archive.
Speed classes: V30 = 30 MB/s sustained (4K30 video), V60 = 60 MB/s (4K60 video), V90 = 90 MB/s (8K video). For Steam Deck and Nintendo Switch: microSD A2 for fast game loading. Action camera 4K: V30 is enough — cinema camera: V90.
USB sticks and external SSDs come in different speed grades: USB 3.0 = 5 Gbps, USB 3.2 Gen 2 = 10 Gbps, USB 3.2 Gen 2×2 = 20 Gbps (rare in laptops), Thunderbolt 3/4 = 40 Gbps. Match the laptop spec — a USB 3.2 SSD on a USB 2.0 port only delivers 40 MB/s.
Sensitive data on the go? Models with hardware AES-256 encryption and PIN keypad on the stick are the safest option. Software encryption (BitLocker / FileVault) is free and equally secure but device-bound.
