# 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.

Quick answer: 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.

## Performance

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.

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.

## Pros and Cons

**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


## Verdict

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.

## Frequently Asked Questions

### Is the Silicon Power P34A80 1TB good for gaming?

The P34A80 1TB is a strong gaming drive with 3,200 MB/s reads and consistent TLC write performance. The 1TB capacity holds 15–25 modern AAA titles alongside the OS and applications. Game load times are fast and comparable to other PCIe 3.0 NVMe drives. The TLC NAND ensures game installations and updates proceed at full speed without the cache-exhaustion slowdowns of QLC drives.

### Does the Silicon Power P34A80 1TB have a DRAM cache?

Yes. The P34A80 1TB includes SK Hynix DDR4 DRAM (two 256 MB chips) that serves the Phison E12 controller's flash translation layer. This DRAM cache provides consistent random IO performance under mixed workloads and is a significant advantage over DRAM-less NVMe drives that must use system RAM through Host Memory Buffer.

### What is the TBW endurance of the P34A80 1TB?

The P34A80 1TB is rated at 708 TBW (terabytes written), covered by a five-year limited warranty. At a typical consumer workload of 30–50 GB per day, the endurance budget lasts 38 to 64 years. Even at a heavy 100 GB per day, it would take 19 years to exhaust the TBW allowance. For normal desktop and gaming use, endurance is not a concern.

### How does the P34A80 1TB compare to the ADATA SX8200 Pro?

Both drives use the Phison E12 controller with Toshiba 64-layer TLC NAND. Performance is nearly identical since the hardware is the same reference design. The SX8200 Pro sometimes ships with slightly different firmware configurations and may have a different SLC cache strategy. Pricing fluctuates, but the P34A80 is typically a few dollars less expensive. Both are excellent TLC NVMe drives that deliver consistent performance.

### Is the P34A80 1TB good for video editing?

The P34A80 1TB works well as a video editing drive with 3,000 MB/s sustained writes and 708 TBW endurance. Transferring 4K footage is fast, and the TLC NAND maintains consistent write speeds even after the SLC cache fills — important for long render jobs. The 1TB capacity provides room for project files and render caches. For professional 4K or 8K workflows with very large files, a PCIe 4.0 drive with higher write speeds would be a better choice.

### Is the P34A80 1TB compatible with the PS5?

The P34A80 is a PCIe 3.0 drive, and the PS5 requires PCIe 4.0 or faster NVMe SSDs for its expansion slot. The P34A80 does not meet Sony's published requirements for PS5 storage expansion and will not work in the PS5 M.2 slot. For PS5 expansion, look for a PCIe 4.0 drive with at least 5,500 MB/s reads.
