# Patriot Viper PV573 2TB PCIe 5.0 NVMe SSD (2026)

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.

Quick answer: 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.

## Performance

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.

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, TBW & 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.

## Pros and Cons

**Pros:**

- 14,000 MB/s rated sequential reads
- 12,000 MB/s rated sequential writes
- 232-layer TLC NAND
- PCIe 5.0 x4 interface
- 2 TB capacity suits creators and gamers
**Cons:**

- Controller not publicly specified
- 3-year warranty vs 5 years on many competitors
- No included heatsink
- Requires PCIe 5.0 M.2 slot for rated speeds
- PV593 offers better value at similar pricing


## Verdict

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.

## Frequently Asked Questions

### Is the Patriot Viper PV573 2 TB good for gaming?

The PV573 2 TB is a fast drive with plenty of capacity for gaming, but PCIe 5.0 speeds do not meaningfully improve game load times compared to PCIe 4.0 drives. Game loading is dominated by random I/O and CPU decompression, not sequential bandwidth. The 2 TB capacity is the primary benefit for gamers — enough room for an OS plus a large game library. For gaming-only builds, a cheaper PCIe 4.0 drive like the Samsung 990 Pro 2 TB delivers an identical gaming experience.

### What controller does the Patriot Viper PV573 use?

The controller is not disclosed in Patriot's publicly available specifications for the PV573. This is unusual for a drive at this performance tier, where most competitors clearly state the controller vendor and model. The rated speeds of 14,000/12,000 MB/s are achievable with several PCIe 5.0 controller platforms, including the Phison E26 and Silicon Motion SM2508, but without confirmation, sustained write behavior and thermal characteristics remain uncertain.

### What is the endurance rating of the PV573 2 TB?

The PV573 2 TB is rated at 2.0 PBW (2,000 TBW). At a typical enthusiast write workload of 40 GB per day, this translates to approximately 137 years before reaching the endurance limit. The 3-year warranty will expire well before the TBW rating becomes a practical concern under any realistic consumer workload.

### Does the PV573 2 TB need a heatsink?

A heatsink is recommended for any PCIe 5.0 NVMe drive, including the PV573. PCIe 5.0 controllers generate significantly more heat than PCIe 4.0 models, and sustained writes can push temperatures high enough to trigger thermal throttling. Without a disclosed controller, it is not possible to predict exact thermal behavior, but erring on the side of additional cooling is prudent. Most motherboards with PCIe 5.0 M.2 slots include integrated heatsinks that should be sufficient.

### How does the PV573 compare to the PV593?

Both are Patriot PCIe 5.0 drives, but the PV593 uses the well-documented Silicon Motion SM2508 controller and claims higher write speeds (14,000 vs 12,000 MB/s). The PV593 also has the advantage of lower power consumption and heat output thanks to the SM2508's efficient 4-channel design. The PV573 has a slightly lower rated write speed and an undisclosed controller. If pricing is similar, the PV593 is the stronger choice due to its known controller platform and better thermal characteristics.

### Is the PV573 2 TB compatible with the PS5?

The PV573 is a PCIe 5.0 drive and is backward compatible with the PS5's PCIe 4.0 M.2 slot, but performance will be capped at PCIe 4.0 speeds. Sony recommends NVMe drives with 5,500 MB/s or higher sequential reads, which the PV573 easily exceeds even on PCIe 4.0. However, without knowing the controller, power draw characteristics are uncertain — some PCIe 5.0 controllers run hotter than Sony recommends. A native PCIe 4.0 drive is a more reliable and cost-effective choice for PS5.
