# Patriot Viper PV573 4TB Review — Blower-Cooled Gen5 Storage (2026)

The Patriot Viper PV573 4TB pairs a rated 14,000/12,000 MB/s of PCIe 5.0 bandwidth with its own blower fan — a 4 TB Gen5 drive that cools itself.

Quick answer: The Patriot Viper PV573 4TB makes sense for a Gen5 desktop owner who needs 4 TB of very fast storage and does not mind powering a blower fan: video editors, AI dabblers, and library builders are the target. Skip it for a PS5 — the 16.5 mm cooler physically exceeds Sony's 11.25 mm limit — for cramped small-form-factor cases, or if waiting for independent benchmark coverage of retail units matters. The Crucial T705 4TB is the established alternative with slightly higher rated speeds and a long review record, while the TeamGroup T-Force GE Pro shares the same IG5666 platform. We would call the PV573 a well-engineered niche play: exceptional rated endurance and self-cooling, with real-world proof still to come.

## Performance

Patriot rates the Viper PV573 4TB at 14,000 MB/s sequential reads and 12,000 MB/s writes, with 2,000K random-read and 1,650K random-write IOPS — figures from the launch spec sheet, mirrored across retail listings. Independent benchmarks of retail units are still scarce, so this section leans on rated numbers rather than measured runs; treat the figures as manufacturer ceilings.

The platform's expected character is easier to describe. The IG5666 is an eight-channel Gen5 controller, and with 4 GB of DDR4 DRAM holding the flash translation tables, sustained behavior should be far more stable than DRAM-less Gen5 designs that collapse once the SLC cache empties. The 4 TB of TLC NAND also gives the controller deep parallelism, which is where large-drive sustained writes traditionally gain. On a Gen4 board, the same drive runs at roughly half these ceilings. For the intended workloads — 4K video scrubbing, large dataset moves, DirectStorage-style asset streaming, and multi-hundred-gigabyte game installs — the rated headroom is real even though game load times will look identical to a fast PCIe 4.0 drive. The blower cooler exists because this class of controller draws serious power under load; Newegg's listing puts active power around 12 W.

## Endurance, TBW & Warranty

Patriot rates the Viper PV573 4TB at 3,000 TBW of total writes, among the highest endurance budgets available in a consumer drive, under a 5-year global warranty. At a heavy 50 GB of writes per day, the budget stretches beyond 160 years, so the warranty term — not the NAND — is the practical limit for any realistic desktop workload. Patriot specifies 4K LDPC error correction and advanced wear leveling to back the rating. The blower fan itself is rated for 25,000 hours of operation per launch coverage, and because it is part of the cooling solution rather than an accessory, keep it unobstructed in the case. Warranty claims run through Patriot's global support network, with the five-year term applying worldwide per the launch announcement.

## Pros and Cons

**Pros:**

- Rated 14,000/12,000 MB/s on PCIe 5.0 x4
- 3,000 TBW endurance on the 4TB model
- 5-year global warranty
- 4 GB DDR4 DRAM cache on board
- 2,000K random-read IOPS rating
- Blower fan rated for 25,000 hours
**Cons:**

- 16.5 mm cooler exceeds the PS5's 11.25 mm limit
- Blower fan needs its own power connection
- Draws around 12 W under load
- No independent retail benchmarks published yet
- NAND vendor not officially named


## Verdict

The Patriot Viper PV573 4TB makes sense for a Gen5 desktop owner who needs 4 TB of very fast storage and does not mind powering a blower fan: video editors, AI dabblers, and library builders are the target. Skip it for a PS5 — the 16.5 mm cooler physically exceeds Sony's 11.25 mm limit — for cramped small-form-factor cases, or if waiting for independent benchmark coverage of retail units matters.

## Frequently Asked Questions

### Is the Patriot Viper PV573 4TB compatible with the PS5?

No. Sony's published requirements cap drive height at 11.25 mm including the heatsink, and the PV573's blower-cooled assembly stands 16.5 mm tall — it physically cannot fit the PS5's slot. The speed side would be overkill anyway: the PS5's slot runs at PCIe 4.0, where this drive's Gen5 rating would be halved, and Sony recommends 5,500 MB/s reads that far cheaper Gen4 drives meet. For console storage, pick a low-profile PCIe 4.0 4 TB drive with a slim heatsink that clears the height limit.

### Does the Patriot Viper PV573 have a DRAM cache?

Yes — and a large one. The 4 TB model carries 4 GB of DDR4 DRAM, per Patriot's retail listings, which store the flash translation tables on the drive rather than in system memory. Combined with the eight-channel IG5666 controller, that DRAM is what keeps sustained and random performance stable under heavy mixed workloads, where DRAM-less Gen5 designs fall back on Host Memory Buffer and settle noticeably lower. For buyers comparing Gen5 drives for sustained creative workloads, the on-package DRAM is one of the PV573's stronger arguments.

### Is the Patriot Viper PV573 4TB good for gaming?

For a PC, yes — with realistic expectations. The 4 TB capacity holds a serious library of modern installs that routinely run 100 GB or more, the rated 14,000 MB/s reads give DirectStorage titles headroom, and the 2,000K random-read rating keeps load times competitive. But games rarely saturate sequential bandwidth, so load times will closely match a fast PCIe 4.0 drive; Gen5's gaming benefit today is capacity and future-proofing, not visibly faster levels. Note the console exclusion: the 16.5 mm cooler does not fit a PS5.

### What is the TBW endurance of the Patriot Viper PV573 4TB?

3,000 TBW — Patriot's own product page, the launch spec sheet, and retail listings all carry the figure, making this one of the highest endurance ratings in the consumer market. At a sustained 50 GB of writes per day, which is heavier than most desktop workloads ever produce, the budget would run past 160 years. The 5-year global warranty is therefore the practical limit rather than flash wear. Many competing Gen5 drives rate lower at this capacity, so Patriot is clearly positioning the PV573 for sustained professional write loads.

### Does the Viper PV573 need a heatsink?

No — it ships with one, and it is not the usual passive slab. The 16.5 mm aluminum heatsink integrates a blower fan that Patriot claims improves cooling by more than 40 percent over passive designs, with launch coverage specifying an 8,000 RPM fan rated for 25,000 hours. Two installation notes follow: the fan draws power from the PSU rather than the M.2 slot alone, so plan the cabling, and do not stack a motherboard's own M.2 heatsink on top. Check clearance above the slot before buying — shrouded slots and tight cases may not fit the assembly.

### Patriot Viper PV573 4TB or Crucial T705 4TB?

The T705 is the reviewer-proven flagship, rated slightly faster at 14,500/12,700 MB/s, with a long independent benchmark record and both bare and heatsink versions on the market. The PV573 answers with active cooling built in, a 3,000 TBW endurance budget, and a 5-year global warranty. Choose the T705 if proven real-world results and ecosystem maturity matter most; choose the PV573 if the workload is sustained heavy writing, where active cooling and the endurance rating carry the argument. Both are desktop drives — neither fits a PS5.
