Patriot Viper PV573 2TB PCIe 5.0 NVMe SSD
The Patriot Viper PV573 2 TB is a PCIe 5.0 NVMe drive rated at 14,000 MB/s sequential reads, built with 232-layer TLC NAND and available in 2 TB and 4 TB capacities.

The PV573 sits in Patriot's PCIe 5.0 lineup between the SM2508-based PV593 and the E26-based PV553. With rated sequential reads of 14,000 MB/s and writes of 12,000 MB/s, it targets the upper tier of PCIe 5.0 performance. The drive uses 232-layer TLC NAND and fits the M.2 2280 form factor. Patriot offers the PV573 in 2 TB and 4 TB capacities.
The controller and DRAM configuration are not specified in publicly available documentation, which is uncommon for drives at this performance level. Most competitors clearly disclose whether they use the Phison E26, Silicon Motion SM2508, or another platform. This lack of transparency makes it harder to predict sustained write behavior, thermal characteristics, and firmware maturity compared to drives with known controllers. For a drive priced in the PCIe 5.0 performance tier, the undisclosed controller is a meaningful gap in the spec sheet.
Competitors in the 14,000+ MB/s PCIe 5.0 class include the Crucial T705, Patriot's own PV593 (SM2508-based, lower power), and the WD Black SN850X (PCIe 4.0, frequently cross-shopped on price). The PV573's value proposition depends heavily on its street price — if priced below comparable drives with disclosed controllers, it can be a reasonable value pick. If priced similarly to the PV593 or Crucial T705, the better-documented alternatives are the stronger choice. Builders should also consider that the unknown controller means thermal behavior is unpredictable, which complicates cooling decisions in compact builds.
✅ Storage Comparisons:
🚀 Performance and benchmarks
Patriot rates the PV573 2 TB at up to 14,000 MB/s sequential reads and 12,000 MB/s sequential writes. These speeds place it in the upper range of PCIe 5.0 consumer drives, slightly below the PV593's 14,500/14,000 MB/s claims but above most Phison E26 drives that top out around 12,400 MB/s.

- Patriot Viper PV593 1 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 2 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV573 2 TB (this drive): 14,000 MB/s read, 12,000 MB/s write
- Nextorage NN5PRO 1 TB: 12,400 MB/s read, 11,800 MB/s write
Without confirmed controller details, predicting sustained write behavior requires some generalization. Most PCIe 5.0 TLC drives use an SLC write cache for burst performance and drop to native TLC write speeds for sustained transfers. The 2 TB model should have reasonable sustained write performance thanks to sufficient NAND die for write parallelism, but without independent benchmarks, specific sustained write numbers cannot be confirmed.
For real-world desktop use, the PV573 will handle any consumer workload well. Game loading, application launches, and general multitasking performance will be comparable to any other high-end NVMe. The PCIe 5.0 bandwidth advantage is most noticeable in large sequential transfers — moving game libraries, video files, or archives between fast storage devices.
🖥️ Endurance and warranty
The PV573 2 TB carries Patriot's 3-year limited warranty with a listed endurance of 2.0 PBW (2,000 TBW). At a typical enthusiast write workload of 40 GB per day, the endurance translates to roughly 137 years of use. As with all consumer SSDs, the warranty period is the practical limitation rather than the TBW rating. The 3-year warranty is shorter than the 5-year terms offered by Crucial and Samsung on competing drives, which is a notable trade-off at this price tier. Patriot handles warranty service through its standard RMA process. Given the undisclosed controller, long-term firmware support and reliability data are harder to assess compared to drives built on well-known platforms like the Phison E26 or SM2508.

Conclusion
The Patriot Viper PV573 2 TB delivers strong PCIe 5.0 performance at a capacity that suits most enthusiasts and content creators. The main concern is the unspecified controller, which makes it harder to assess thermal behavior and sustained performance compared to alternatives with well-documented platforms. If the PV573 is priced significantly below the PV593 or Crucial T705, it is a reasonable value pick for builders who prioritize raw capacity and speed over controller transparency. If pricing is close, Patriot's own PV593 offers the same speeds with a known, thermally efficient controller and is the stronger recommendation.
