AS SSD Scores Compared: Real Review Results for 15 Drives
This page is an archive, not an estimate. Every number in the table below was recorded by a named review site testing a specific drive with AS SSD Benchmark, and every row links to the original review so you can check the figure yourself. None of these results was measured by this site — they are published review data, collected so you can compare your own run against a real result for the same drive instead of a guessed “typical” range. If your drive is not listed, the method in what is a good AS SSD score shows how to find its review. You can produce your own result with the tool from our download page.
The results table
Speeds are MB/s, shown as read / write. A dash means the review’s text did not state that row — we reproduce exactly what each source published, nothing more.

How the sources tested
Legit Reviews states the AS SSD version in each of its reviews, and the versions vary because the reviews span years: the HyperX Predator and Samsung SM951 results were produced with 1.7.4739.38088, the Crucial BX200 with 1.8.5636.37293, and the Intel 660p, Kingston A1000 and KC1000, Intel Optane 800P and Phison E12 results with 2.0.6485.19676; the WD Blue SN500 review used 2.0.6821.41776. RelaxedTech’s results come from a single comparison review of the Samsung 870 EVO, in which the 970 EVO Plus, Crucial P1, 870 EVO, 860 EVO, MX500 and TR200 were all tested on one bench — those six rows are directly comparable with each other. KitGuru’s Samsung 970 EVO Plus 1 TB review (AS SSD 2.0) is a useful extra data point in a different format: it reports a read score of 2,133 and a write score of 2,258 for the 1 TB model, against the 500 GB model’s total of 4,931 in the table — a reminder that capacity changes results within the same product family.
What the table shows
Three patterns are worth reading out of the data. First, the interface ceiling is visible. The five SATA drives’ totals sit between 823 and 1,242 and their sequential reads between 508 and 558 MB/s — the whole class pressed against the same link limit, as SATA vs NVMe scores explains. Second, sequential speed does not rank the drives. The Intel Optane 800P has the lowest sequential write figure of any NVMe drive in the table (611.58 MB/s) yet a total of 3,309, because its 4K read of 152.75 MB/s is nearly three times the next best in that column — the score formula rewards the 4K row, as Sequential vs 4K discusses. Third, version discipline matters. The two oldest results (HyperX Predator, SM951) were produced under AS SSD 1.7; their totals are historical records, not numbers to rank against the 2.0 rows beneath them.
Extra figures published by the same reviews
Some reviews published rows beyond the table’s columns. Legit Reviews reported the Phison E12 reference drive’s 4K-64Thrd figures in IOPS — 441,299 IOPS read and 427,221 IOPS write (the IOPS view is explained in MB/s vs IOPS explained) — and Copy-Benchmark ranges for several drives, for example 635 MB/s (Program) to 1,783 MB/s (ISO) for the Intel 660p and 486 / 323 / 407 MB/s (ISO / Program / Game) for the Crucial BX200; see Copy-Benchmark explained for how to read those. The compression behaviour behind some of these results is covered in Compression-Benchmark explained.
Using this archive honestly
Compare your result only with the row for your exact drive and capacity, note the version that produced it, and match your test size to the 1 GB default most reviews use. If your numbers land close to the published row, your drive is performing as reviewed; if one row is far off, that row — not the total — tells you where to investigate. And if you are choosing a new drive on benchmark evidence, weigh the 4K column at least as heavily as the sequential column; our best NVMe SSDs guide builds on these same published results. This archive will grow as we verify further published reviews; every addition must pass the same test as the rows above — a named source, a specific drive, and numbers we have read in the original review.
