How to Find the Fastest or Best SSD on SSD Tester

Updated

SSD Tester (ssd-tester.com) publishes benchmark results for M.2 NVMe, SATA, portable, and USB flash drives, and it names a "Current winner" for overall performance — as of the site's 2026 data, the Western Digital WD_BLACK SN8100 1TB. To find the fastest or best SSD for your situation, start with that winner if you want the top performer, then use the category tables (M.2, SATA, external, USB) to compare read/write speeds, capacity, price, and score within the interface type you actually need.

What SSD Tester provides

The site is a benchmark and review database rather than a shop. Its stated purpose is to help you make an informed purchase decision using detailed performance, speed, and benchmark reviews. Key features visible on the homepage:

  • Current winner — a highlighted top pick (Western Digital WD_BLACK SN8100 1TB, listed at 1409 in the score column).
  • Category test sections — M.2 SSD Test, SATA SSD Test, External Drives Test, and USB Flash Drive Test.
  • Comparison tables — each row lists product name, capacity, read speed, write speed, price, and score.
  • Regular updates — new models are tested regularly, and Gen5 SSDs are now included.
  • Daily updated shop prices — price fields are refreshed daily, though the site does not sell drives itself.

Step-by-step: finding the fastest or best SSD

  1. Decide which category matches your hardware. M.2 covers PCIe 5.0, 4.0, and 3.0 NVMe drives; SATA covers 6 Gb/s drives; External covers USB-C portable drives; USB covers USB 3.0/3.1/3.2 flash drives. A drive from the wrong category won't fit or won't reach its rated speed in your system.
  2. Check the Current winner first if raw speed is your priority. It represents the site's top-scoring drive across its testing.
  3. Open the relevant category table and sort your attention by the score column, then cross-check read/write speeds. Higher score generally means better overall measured performance in that category.
  4. Filter by capacity and price. The tables show capacity in GB and a price figure, so you can weigh speed against cost per drive.
  5. Confirm the interface ceiling. A SATA SSD tops out around 600 MB/s theoretical (~560 MB/s practical), so don't expect M.2-level speeds there. USB 4.0 external drives can theoretically reach 40 Gbit/s (~3,700 MB/s practical).

How to read the comparison tables

Each category table uses the same columns, which makes cross-model comparison straightforward:

Column What it tells you
Product name The exact model tested
Capacity Drive size in GB
Read / Write Measured sequential speeds in MB/s
Price Daily-updated shop price indicator
Score The site's aggregate benchmark score

Example rows from the M.2 table show how to compare: the fanxiang S880E 1TB lists 7229 MB/s read and 6208 MB/s write with a score of 12755, while the Taimi Phoenix 2TB shows 7466 MB/s read and 6761 MB/s write with a score of 15048 — higher capacity and higher score, but also a higher price figure.

Category-specific notes

M.2 SSD Test

Covers PCIe 5.0 (Gen5), PCIe 4.0, and PCIe 3.0 x4 NVMe drives. This is where the fastest consumer drives appear, and where the Current winner sits.

SATA SSD Test

SATA 6 Gb/s drives, theoretical maximum 600 MB/s (practically ~560 MB/s). Useful if your board or laptop only has SATA ports.

External Drives Test

USB-C portable drives. USB 4.0 allows a theoretical 40 Gbit/s (~3,700 MB/s practical). Note that real-world results depend heavily on the host port and cable.

USB Flash Drive Test

USB 3.0, 3.1, and 3.2 drives. USB 2.0 drives are excluded because the site considers them outdated.

Choosing between drives

  • If you want the single fastest drive: go with the Current winner, then verify it fits your slot type (M.2 NVMe) and that your motherboard supports its PCIe generation.
  • If you're limited to SATA: pick the highest score in the SATA table; expect roughly 550 MB/s read at best.
  • If you need portability: compare External Drives results, but match the drive to your port — a USB 4.0 drive won't hit its ceiling on an older USB port.
  • If budget matters more than peak speed: use the price column alongside score to find the best score per price within your category, rather than defaulting to the top of the list.

Practical caveats

  • Benchmark scores reflect the site's test setup; your real-world speed depends on your CPU, motherboard, port, cable, and how full the drive is.
  • The price column is a daily-updated shop price indicator, not a checkout price — confirm the actual price at the retailer.
  • The site tests and reviews drives; it does not appear to sell them, so treat it as a research tool before buying elsewhere.
