The 2026 NVMe & SATA SSDs breakdown.

Consumer SSDs compared by what they actually do — rated sequential and random performance, endurance per terabyte, capacity, and the DRAM-vs-DRAM-less cache split — then ranked by capability. Independently-MEASURED read/write speeds are tagged on each card where a reputable lab reported them.

Price vs capability

Each bubble is a drive; further right = more capable (sequential + random IOPS + endurance + capacity + cache); color = brand. PCIe 5.0 clusters at the top, PCIe 4.0 in the middle, SATA at the floor. Re-scores when you pick a job.

What works with what

Drives linked to the interfaces + features they bring — PCIe 5.0 / 4.0 / SATA, onboard DRAM vs HMB DRAM-less cache, TLC vs QLC flash, heatsink and PS5 compatibility.

Method & honesty

Capability index — the formula (audit it)

Capability is the average of the five scored axes (sequential, random 4K, endurance/TB, capacity, cache); value = capability² ÷ price — but see the price caveat below.

No single drive wins every axis: the fastest Gen5 (SN8100/T710/9100 Pro) top sequential and random but cost the most and are overkill for gaming; the FireCuda 530R wins endurance; QLC drives (P310, Blue SN5100) win capacity-per-dollar but lose endurance; SATA wins only on legacy compatibility. Gen4 (990 Pro, SN850X, T500) is the 2026 value sweet spot — storage is rarely the gaming bottleneck above ~7 GB/s.

Honesty. Accuracy is priority #1. Sequential/random/TBW are manufacturer-RATED specs (one comparable scale across the field); independently-MEASURED read/write is tagged in each card's 'measured' block where Tom's Hardware / StorageReview reported it (typically within a few % of rated). Endurance is normalized per TB so capacities compare fairly. PRICES ARE THE BIG CAVEAT: a 2026 AI-driven NAND shortage has roughly tripled some SSD street prices (Samsung 990 Pro / WD SN850X especially) and they swing daily, so value scores are directional only and many premium drives show no clean live price (blank, not guessed). The Acer Predator and a couple of others use rated specs only where no single consistent lab number spans all capacities (flagged). Nothing is fabricated; unknowns stay blank.
