SanDisk Solid State Drives

Internal NVMe, SATA, and Portable SSDs for Every Workload

SanDisk and Western Digital SSDs span internal NVMe and SATA models for desktops, laptops, and servers, plus rugged portable USB-C drives for on-the-go storage, with interfaces covering SATA III through PCIe Gen 5. The color-coded WD lineup, Black for performance, Blue for mainstream, Red for NAS, and Green for budget, simplifies selection by matching drive characteristics to workload. The full lineup sits within the broader Western Digital family of hard drives, flash drives, and memory cards, and you can compare across all brands in the complete storage category.

SanDisk Solid State Drives for Every Use Case

• Gaming and content creation — WD Black SN850X delivers PCIe Gen 4 speeds up to 7,300 MB/s sequential reads for fast game loading and video rendering, while the SN8100 pushes into PCIe Gen 5 for next-generation motherboards
• Mainstream computing and fleet upgrades — WD Blue SA510 (2.5-inch SATA) and SN5000 (M.2 NVMe) provide meaningful speed upgrades over mechanical hard drives at mainstream prices for office desktops and laptop refreshes
• NAS caching and storage tiers — WD Red SA500 (SATA) and SN700 (NVMe) are tuned for the mixed read/write workloads, vibration tolerance, and endurance ratings that multi-bay NAS enclosures demand
• Portable field storage — SanDisk Extreme and Extreme PRO portable SSDs deliver up to 2,000 MB/s in pocket-sized, IP65-rated enclosures for photographers, videographers, and field professionals
• Budget builds and point-of-sale systems — WD Green SSDs deliver the core benefits of solid-state storage, no moving parts, faster boot times, and silent operation, at the lowest price per gigabyte in the lineup

Choosing the Right SanDisk SSD

Western Digital's color-coded system simplifies SSD selection. Black is the highest-performance line for gaming, video editing, and creative workstations. Blue is the mainstream choice for everyday computing where the goal is a meaningful upgrade from a mechanical drive. Red is purpose-built for NAS environments. Green is the budget option for basic computing. Portable SSDs from the SanDisk Extreme line serve users who need to move large files between machines or work in the field.

NVMe vs. SATA

If your system has an M.2 slot, NVMe drives like the WD Blue SN5000 or WD Black SN850X outperform SATA drives by a factor of five to ten in sequential transfer speeds. SATA drives like the WD Blue SA510 remain the right choice for older laptops and desktops that lack an M.2 slot, and for NAS appliances that use 2.5-inch drive bays.

Internal vs. Portable

Internal SSDs deliver the best performance per dollar and are the right choice for primary boot drives, game libraries, and NAS caching. Portable SSDs like the SanDisk Extreme PRO make sense when you need to move large files between machines, shoot in the field, or maintain a transportable backup that is faster than a traditional external hard drive.
