Samsung 860 PRO 1TB SATA SSD (S tier)
Samsung 860 PRO 1TB SATA SSD
The Samsung 860 PRO uses MLC NAND — the most durable NAND type available in consumer SSDs — giving it endurance ratings that dwarf TLC-based competitors and sustained write performance that doesn't degrade after the cache fills. It's the right choice for write-heavy workloads like video editing scratch disks or servers, though for typical desktop use the endurance advantage is more than you'll ever need.
Samsung 860 PRO 1TB SATA SSD (S tier)
Samsung 860 PRO 1TB SATA SSD
Same drive as B078WR35K7 — the Samsung 860 PRO 1TB with MLC NAND and the MJX controller. MLC endurance and consistent performance under sustained writes put it at the top of the SATA category.
Samsung 860 EVO 1TB SATA SSD (S tier)
Samsung 860 EVO 1TB SATA SSD
The Samsung 860 EVO is the most widely deployed SATA SSD ever made, combining V-NAND TLC with a DRAM cache and Samsung's MJX controller into a package that delivers consistent real-world performance across every workload type.

Samsung 870 EVO 1TB SATA SSD (S tier)
Samsung 870 EVO 1TB SATA SSD
The Samsung 870 EVO is the definitive SATA SSD — its MJX controller, V-NAND TLC, and DRAM cache deliver the most consistent real-world performance in the category, with endurance ratings that exceed most competing TLC drives. It's the benchmark against which every other SATA SSD is measured, and it earns that status.
A
Transcend SSD230 1TB SATA SSD (A tier)
Transcend SSD230 1TB SATA SSD
The SSD230S uses 3D TLC NAND with a DRAM cache, LDPC error correction, and an SLC write buffer — a solid, well-rounded package from a reputable brand. It falls just short of S-tier because its controller and NAND don't match the sustained performance consistency of Samsung's MJX-based drives.
Angelbird AtomX SSDmini 1TB SATA SSD (A tier)
Angelbird AtomX SSDmini 1TB SATA SSD
The Angelbird AtomX SSDmini is purpose-built for continuous video recording on Atomos devices, with endurance and thermal characteristics tuned for that specific workload — it genuinely outperforms general-purpose SSDs in that niche. For standard PC or laptop use, it's overspecified and overpriced relative to what you actually need.
Samsung 850 PRO 1TB SATA SSD (A tier)
Samsung 850 PRO 1TB SATA SSD
The Samsung 850 PRO was the gold standard of its era, using MLC V-NAND with Samsung's MEX controller and delivering endurance that still holds up today.

Western Digital WD Red SA500 1TB SATA SSD
The WD Red SA500 is specifically validated for NAS enclosures with 24/7 operation, vibration compensation, and higher endurance ratings than standard desktop SSDs — it's the right tool if you're running a home NAS. For a regular PC or laptop, you're paying for NAS-specific features you won't use.
B
OWC Mercury Extreme Pro 1TB SATA SSD (B tier)
OWC Mercury Extreme Pro 1TB SATA SSD
OWC's Mercury Extreme Pro 6G uses quality NAND and is well-regarded for Mac upgrades, but at this price point it doesn't offer a compelling advantage over Samsung or WD drives that cost significantly less. It's a reliable drive, but you're paying a premium that isn't justified by performance data.
WD Blue SA510 1TB SATA SSD (B tier)
WD Blue SA510 1TB SATA SSD
The WD Blue SA510 is a competent mainstream SATA SSD from a trusted brand, but it's DRAM-less — relying on HMB — which means performance degrades more noticeably under sustained writes compared to DRAM-equipped drives. Fine for a secondary drive or light-use laptop, but not the best choice for a primary OS drive under heavy workloads.
Transcend SSD225 1TB SATA SSD (B tier)
Transcend SSD225 1TB SATA SSD
The Transcend SSD225 is a budget-oriented TLC drive with SLC cache and LDPC error correction, but it lacks a DRAM buffer, which limits its sustained write performance. It's a step down from the SSD230S and better suited to light use cases like PS4 upgrades or secondary storage.
WD Blue SA510 1TB M.2 SATA SSD (B tier)
WD Blue SA510 1TB M.2 SATA SSD
This is the M.2 2280 SATA form factor version of the WD Blue SA510 — it belongs in this category as a SATA SSD, but the M.2 slot it occupies could otherwise hold an NVMe drive, making this a questionable choice for new builds. It's fine for systems where M.2 NVMe isn't an option.
SanDisk Ultra 3D 1TB SATA SSD (B tier)
SanDisk Ultra 3D 1TB SATA SSD
The SanDisk Ultra 3D is a DRAM-less TLC drive that performs well for light workloads but throttles under sustained writes — a known limitation of this design.

1TB SATA SSD Criteria

S-tier SATA SSDs use MLC or high-quality TLC NAND paired with a DRAM cache and a proven controller, which together maintain consistent speeds under sustained workloads rather than throttling once the SLC write buffer fills. The Samsung 870 EVO is the benchmark here: its MJX controller, DRAM buffer, and V-NAND deliver predictable performance across sequential and random workloads, plus industry-leading endurance ratings. At this tier, firmware maturity and long-term reliability data from millions of real deployments matter as much as peak specs.

Mid-tier drives (B and C) typically use 3D TLC NAND with an SLC cache and may or may not include a DRAM buffer. DRAM-less designs rely on the host system's RAM via HMB, which works fine for light desktop use but degrades noticeably under sustained writes like large file transfers or OS installs. Brands like WD Blue, Crucial BX500, and SanDisk Ultra 3D land here — they're competent for everyday computing but won't hold up as well in write-heavy or NAS scenarios. The gap between B and C often comes down to whether the drive has DRAM and how well the manufacturer's firmware handles cache exhaustion.

D and F tier drives are typically no-name or obscure brands with unverified NAND sourcing, no DRAM, weak or undisclosed controllers, and little to no track record in independent testing. These drives may advertise competitive sequential read speeds but collapse under random I/O or sustained writes. Buying an unvalidated SSD for primary storage is a real data-loss risk — the savings are not worth it when established alternatives exist at similar price points.
