Samsung 990 EVO Plus vs WD Blue SN5100 1TB: Which Fits Your PC and Migration Plan?

Both are 1TB M.2 2280 NVMe drives with five-year and 600TBW published warranty limits. Their form factor and published interface details make host verification the first step. For migration, WD advertises an Acronis license with conditions; Samsung documents Data Migration in Magician, but its support list shows the BW code, not this US AM code. Verify exact compatibility before treating either tool as ready for your system. The published maximum throughput figures do not establish a real-world winner.

The buying question

Which drive should I choose after confirming my host's M.2 slot and the migration software I can actually use?

The documented format and warranty are similar; the useful distinction is how each manufacturer describes host support and migration software, with exact system and SKU compatibility still needing confirmation.

Quick verdict

Choose Samsung 990 EVO Plus 1TB (MZ-V9S1T0B/AM) if

  • Your host manual confirms a compatible M.2 2280 NVMe slot and Samsung confirms Data Migration support for MZ-V9S1T0B/AM in your current software and migration setup.

Choose WD Blue SN5100 1TB (WDS100T5B0E) if

  • Your host manual confirms a compatible M.2 2280 NVMe slot and the Acronis license and compatibility conditions for WDS100T5B0E fit your migration plan.

When to skip: Your computer has no available M.2 2280 NVMe slot; check its service manual before selecting either drive.
When the recommendation changes
  • The recommendation changes with the motherboard or laptop's available M.2 NVMe slot, PCIe generation, and physical clearance.
  • It also changes if the exact Samsung US variant is confirmed as supported by Data Migration or if Acronis's terms do not suit the buyer's source drive, operating system, or redemption timing.

The differences that matter

Host Compatibility And Physical Fit

Samsung 990 EVO Plus 1TB (MZ-V9S1T0B/AM)

The US listing identifies the Samsung 990 EVO Plus 1TB as MZ-V9S1T0B/AM. Samsung's family datasheet lists M.2 2280, maximum dimensions 80.15 x 22.15 x 2.38 mm, PCIe 4.0 x4 / 5.0 x2, backward compatible with PCIe 4.0 x4 and 3.0 x4.[1, 2]

WD Blue SN5100 1TB (WDS100T5B0E)

SanDisk's US product page and datasheet identify the WD Blue SN5100 1TB as WDS100T5B0E-00CPE0 and list M.2 2280, 80 x 22 x 2.38 mm, PCIe 4.0 x4, and earlier-generation PCIe compatibility.[4, 5]

What this changes: Because both specifications name M.2 2280, check whether the host has an available NVMe M.2 slot and sufficient clearance; the host manual is needed to verify a real system fit.[2, 5]

The better fit depends on your priorities

Model Specific Warranty And Migration Support

Samsung 990 EVO Plus 1TB (MZ-V9S1T0B/AM)

Samsung's 990 EVO Plus 1TB datasheet lists five years limited and 600 TBW, whichever comes first. Samsung Magician documents Data Migration; its supported-model list includes MZ-V9S1T0BW (1TB) but not the listed US part code MZ-V9S1T0B/AM. Exact AM variant eligibility remains unknown.[2, 3]

WD Blue SN5100 1TB (WDS100T5B0E)

The WD Blue SN5100 1TB datasheet lists five years limited or 600 TBW, whichever comes first, and advertises Acronis True Image for compatible drives with a five-year license that must be redeemed within 90 days, subject to offer terms.[5]

What this changes: The published basic warranty limits align, while migration requires checking exact software eligibility and terms. A buyer should not treat either migration tool as guaranteed for an unspecified source drive, operating system, or regional SKU.[2, 3, 5]

The better fit depends on your priorities

Best for your routine

A buyer whose PC has a confirmed M.2 2280 NVMe slot

No clear winner

Both product documents describe M.2 2280 NVMe drives. The buyer's host manual, slot generation, lane support, and clearance determine fit; these specifications do not show a universal advantage for either drive.

A buyer moving an operating system or data from an existing drive

The better fit depends on your priorities

WD advertises Acronis under a time-limited license with compatibility conditions. Samsung documents Data Migration in Magician, but its published supported-model list uses the BW code rather than the exact US AM code. Confirm the exact software support and source-drive requirements before choosing.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Compare the current offers after confirming both are the intended 1TB models; a price difference matters only if the host-fit or migration requirements apply to your setup.

There is not enough price history to say Buy Now or Wait. Check the current offers and confirm the exact 1TB model before purchasing.

Limitations

  • No hands-on, benchmark, sustained-write, thermal, or side-by-side performance testing was performed; published maximum rates do not predict this system's real-world result.
  • Check the host's service manual for a free M.2 NVMe 2280 slot, interface generation and lanes, and heatsink/clearance before buying; no particular host was evaluated.
  • Samsung's global Magician model list names MZ-V9S1T0BW and does not list the US MZ-V9S1T0B/AM code. That omission is not proof that the US SKU is unsupported; verify the current compatibility list or support response before relying on Data Migration.
  • SanDisk describes Acronis for compatible drives and gives redemption and offer conditions. Confirm the current terms and that the buyer's source drive and operating system qualify.
  • Warranty terms can have regional conditions. The listed five-year/600TBW figures are manufacturer-published terms; consult the applicable US warranty statement for claim eligibility.
  • Prices and offers can change. Verify the current offer and exact 1TB model before purchase; no price-timing recommendation is made.

Questions shoppers ask

Does M.2 2280 mean either drive will fit my laptop or motherboard?

No. It describes the drive format, not your host's available slot, NVMe support, lane wiring, or surrounding clearance. Check the model-specific service or motherboard manual before buying.

Can I count on Samsung Data Migration for the US 990 EVO Plus 1TB?

Samsung describes Data Migration as a Magician feature and lists a 990 EVO Plus 1TB BW code on its supported-model page. The page does not show the US MZ-V9S1T0B/AM code, so confirm that exact variant and your migration setup with current Samsung support. The omission alone does not prove it is unsupported.

Methodology and sources

Compared exact 1TB model codes, form factor, interface/host compatibility notes, published warranty terms, and manufacturer migration-software documentation. No sequential-rate or other maximum specification was treated as a real-world performance result.

Research assistance was used to locate and organize official manufacturer material. No hands-on comparison or product testing was performed.
