Lexar NS100 vs NM620 SSD: SATA or NVMe for Your Laptop?
Lexar NS100 vs NM620: Despite sharing a brand, NS100 and NM620 use different connections. NS100 is a 2.5-inch SATA SSD; NM620 is M.2 PCIe Gen3x4 NVMe. A correct comparison starts with the laptop, not the SSD’s marketing.
Technical comparison and key compatibility points
Choosing storage correctly requires verifying interface, form factor, manufacturer part number and the destination computer. An internal SATA SSD, an M.2 NVMe laptop SSD and an M.2 expansion drive for PlayStation 5 do not automatically serve the same equipment.
- A 2.5-inch SATA drive such as NS100 is relevant where the laptop has a compatible bay and SATA connector.
- NM620 requires an M.2 socket that supports PCIe NVMe and an appropriate module mounting position.
- An M.2-shaped SATA socket does not necessarily support NM620, even if the drive’s physical shape looks close.
- SATA SSDs are already a major step up from old mechanical hard disks for many tasks.
- An NVMe SSD can transfer large sequential files faster on suitable hardware, but does not solve problems caused by too little RAM.

Buying decision: five steps
- Check the exact device: note the laptop serial/service tag, motherboard type or console model before ordering an SSD.
- Confirm the slot: compare PCIe NVMe, M.2 SATA and 2.5-inch SATA requirements using official technical documentation.
- Check space and purpose: weigh 500GB/512GB, 1TB or 2TB capacity against actual file and game-library needs.
- Review costs: compare prices, warranty terms and any required heatsink, screws, caddy or adapter.
- Protect your data: maintain a backup before cloning or installing Windows, and verify the new drive after installation.
Common questions
Can I swap NS100 for NM620 without changing hardware?
Not unless the computer has the required separate NVMe slot; the connections differ.
Which is better for an old laptop?
Choose the interface actually supported. Many older HDD-based laptops benefit from a 2.5-inch SATA SSD.
