Buy the WD_Black SN7100 2TB.

It is faster, cheaper, and built for the sockets modern PCs actually have.

What was compared

  • WD_Black SN7100 2TB NVMe SSD - Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,9... — $304.00
  • Samsung SSD 870 EVO SATA III 2.5” 2TB, Read Speeds Up to 560MB/s | SATA Internal Solid Sta... — $490.96

Five reasons

  1. 1. Files move in seconds, not minutes

    The SN7100 hits up to 7,250 MB/s sequential read against the 870 EVO's 560 MB/s SATA ceiling, a gap that shows up every time you copy a game install, export video, or boot Windows. That is not a lab number you never touch, it is every big file operation you do.

  2. 2. Cheaper and still the faster drive

    At $304 the SN7100 undercuts the 870 EVO's $490.96 by over $180 for the same 2TB, and you are not trading speed for that saving, you are getting more of it. The 870 EVO asks a premium for a SATA interface that tops out decades below what NVMe already delivers.

  3. 3. Fits the laptop and handheld you actually own

    M.2 2280 slots straight into modern laptops, mini PCs and handhelds like Steam Deck with no cable, no drive bay, no extra weight. The 870 EVO needs a 2.5 inch bay and a SATA cable, hardware most thin modern machines simply do not have anymore.

  4. 4. Built on an interface with room left to grow

    SATA III has been capped at roughly 560 MB/s since 2013 and nothing changes that, it is a dead end. PCIe Gen4 still has headroom for faster CPUs and boards down the line, so the SN7100 ages better inside a system you will keep upgrading around it.

  5. 5. Yes, SATA fits more old PCs. Still skip it.

    If you are upgrading a decade-old desktop with zero M.2 slots, the 870 EVO's SATA connector is genuinely the only one that will work, and that is a real reason to buy it. But most people buying a fresh 2TB drive today are building or upgrading a machine from the last few years that already has an M.2 slot, so that compatibility rarely gets used.
