Silicon Power P34A80 1TB NVMe SSD Review (2026)
The Silicon Power P34A80 1TB is the flagship capacity of this Phison E12-based NVMe lineup, offering 3,200 MB/s reads, 708 TBW endurance, and enough space for a full OS, game library, and working files on a single drive.
Controller & Memory
The P34A80 1TB uses the Phison PS5012-E12 eight-channel controller with Toshiba BiCS3 64-layer 3D TLC NAND and an SK Hynix DDR4 DRAM cache. The 1TB model has the most NAND die of the P34A80 range, which means the best parallel-write performance and the largest dynamic SLC cache. Silicon Power rates it at 3,200 MB/s sequential reads and 3,000 MB/s sequential writes.
The drive is double-sided with NAND packages and DRAM on both faces of the M.2 2280 PCB. Endurance comes in at 708 TBW — the highest in the P34A80 range and competitive with other Phison E12 1TB drives. The ECFM12.1 firmware that Silicon Power ships is newer than the firmware on some earlier Phison E12 drives, and AnandTech's testing showed it delivers competitive performance.
At 1TB, the P34A80 targets users who want a single-drive solution for OS, games, and working files. Direct competitors include the Corsair Force MP510 960GB (same E12 platform), the WD Black SN750 1TB (WD's in-house controller), and the ADATA SX8200 Pro 1TB (also Phison E12). Silicon Power's typical pricing advantage makes the P34A80 1TB one of the most affordable 1TB TLC NVMe drives with DRAM cache.

P34A80 Performance & Benchmarks
The P34A80 1TB is rated for 3,200 MB/s sequential reads and 3,000 MB/s sequential writes, with 390K random read IOPS and 450K random write IOPS. The 1TB model saturates the Phison E12's write pipeline thanks to its higher die count, and sustained TLC writes after SLC cache exhaustion hold around 1,500–2,000 MB/s — a key advantage over QLC drives that can drop below 200 MB/s.

- ADATA SX 8800 Pro 512 GB: 3,500 MB/s read, 2,700 MB/s write
- ADATA SX 8800 Pro 1 TB: 3,500 MB/s read, 2,700 MB/s write
- ADATA XPG Spectrix S40G RGB 256 GB: 3,500 MB/s read, 3,000 MB/s write
- ADATA XPG Spectrix S40G RGB 512 GB: 3,500 MB/s read, 3,000 MB/s write
- Silicon Power P34A80 1 TB (this drive): 3,200 MB/s read, 3,000 MB/s write
AnandTech tested the P34A80 with the ECFM12.2 firmware and found it competitive with other Phison E12 drives, delivering solid real-world performance in PCMark and SYSmark benchmarks. The drive's slight disadvantage versus WD's in-house controller (WD Black SN750) in some workloads is attributable to Silicon Power's configuration with less spare area (1024 GB usable vs. 960–1000 GB on some competitors). For everyday desktop use and gaming, the difference is imperceptible. Content creators will find the sustained write consistency valuable for video scratch disks and large file transfers.

Endurance, TBW & Warranty
Silicon Power rates the P34A80 1TB at 708 TBW with a five-year limited warranty. At 40 GB of writes per day — a heavy desktop workload — the endurance budget covers roughly 48 years. The five-year warranty period is the practical limit for most users, and the 708 TBW endurance provides substantial headroom. Warranty claims are handled through the retailer or Silicon Power's direct RMA portal.

Verdict: Is the P34A80 Worth It in 2026?
The Silicon Power P34A80 1TB is the best overall value in this lineup — enough capacity for a full system build, proven Phison E12 and Toshiba TLC hardware, 708 TBW endurance, and typically the lowest price among 1TB TLC NVMe drives with DRAM cache. Its weakness is that it is a PCIe 3.0 drive in an era where PCIe 4.0 and 5.0 are the new standards, but for motherboards that only support PCIe 3.0, or for budget builds where Gen4 pricing is hard to justify, the P34A80 1TB delivers reliable TLC performance. The Corsair MP510 and ADATA SX8200 Pro are near-identical alternatives to compare on price.
+ Pros
- 3,200 MB/s reads and 3,000 MB/s writes on PCIe 3.0
- 708 TBW endurance with 5-year warranty
- Phison E12 with Toshiba 64L 3D TLC and DRAM cache
- Consistent sustained writes — no QLC collapse
- Typically the most affordable 1TB TLC NVMe with DRAM
- Cons
- PCIe 3.0 — half the ceiling of Gen4 drives
- Double-sided PCB may limit slim-laptop compatibility
- Less spare area than some Phison E12 competitors
- Surpassed by PCIe 4.0 drives for peak throughput
- Minimal bundled management software
