# Patriot P300 512GB PCIe 3.0 NVMe SSD (2026)

The Patriot P300 512 GB slots into the middle of Patriot's budget NVMe lineup, pairing a Phison E13T DRAM-less controller with Kioxia 96-layer TLC for 2,100 MB/s reads at a low cost.

Quick answer: The Patriot P300 512 GB is a competent budget NVMe SSD that delivers 2,100 MB/s reads at a price point that makes sense for cost-sensitive builds. It is best suited as a boot drive with room for several applications and games, or as a secondary drive in a system that already has a faster primary NVMe. Builders who regularly transfer large files or run write-intensive workloads should spend more on a DRAM-equipped drive like the Patriot VPN100. For basic desktop and light gaming duty, the P300 512 GB gets the job done without overcharging for features most users will not miss.

## Performance

Patriot rates the P300 512 GB at up to 2,100 MB/s sequential reads and up to 1,650 MB/s sequential writes, with up to 290,000 random read IOPS and 260,000 random write IOPS. These numbers are identical across the entire P300 capacity range, as the E13T controller's four channels reach their ceiling before NAND quantity becomes a factor.

Compared to SATA SSDs capped at roughly 550 MB/s, the P300 512 GB is a substantial upgrade for OS boot times, application loading, and file transfers. Against DRAM-equipped PCIe 3.0 drives like the Samsung 970 EVO Plus, the P300 falls behind in random write workloads and sustained transfers after the SLC cache fills. The 512 GB model has a larger SLC cache than the 256 GB, which means it can absorb more data before falling back to native TLC write speeds. For everyday desktop use, light gaming, and general productivity, the performance gap between the P300 and more expensive NVMe drives is difficult to notice.

## Endurance, TBW & Warranty

The P300 512 GB carries a 160 TBW endurance rating within Patriot's warranty period. At a typical 20 GB per day write workload, the 160 TBW rating translates to approximately 21 years before reaching the rated limit. The Phison E13T platform uses LDPC error correction for data integrity. Budget drives typically carry lower endurance ratings than enthusiast models, but 160 TBW is adequate for the light to moderate workloads the P300 512 GB is designed for.

## Pros and Cons

**Pros:**

- 2,100 MB/s sequential reads at a low price
- Single-sided M.2 2280 fits laptops and desktops
- Larger SLC cache than the 256 GB variant
- Low power consumption for mobile use
- HMB support keeps costs down
**Cons:**

- DRAM-less design limits random write performance
- SLC cache still modest compared to DRAM-equipped drives
- 160 TBW is lower than enthusiast NVMe drives
- No heatsink or SSD toolbox software included


## Verdict

The Patriot P300 512 GB is a competent budget NVMe SSD that delivers 2,100 MB/s reads at a price point that makes sense for cost-sensitive builds. It is best suited as a boot drive with room for several applications and games, or as a secondary drive in a system that already has a faster primary NVMe. Builders who regularly transfer large files or run write-intensive workloads should spend more on a DRAM-equipped drive like the Patriot VPN100. For basic desktop and light gaming duty, the P300 512 GB gets the job done without overcharging for features most users will not miss.

## Frequently Asked Questions

### Is the Patriot P300 512GB good for gaming?

For casual and mid-tier gaming, the P300 512 GB offers a noticeable improvement over SATA SSDs. The 512 GB capacity fits the operating system plus a handful of modern AAA titles. Gamers who install many large games or want the fastest possible load times should consider a DRAM-equipped NVMe like the Patriot VPN100 or a PCIe 4.0 drive instead.

### Does the P300 512GB have a DRAM cache?

No. The P300 uses Phison's E13T DRAM-less controller with Host Memory Buffer (HMB) support. HMB borrows a small amount of system RAM on Windows 10 version 1709 and later to store the flash translation table. This approach saves cost and power but results in slightly lower random I/O performance compared to drives with dedicated DRAM.

### What is the TBW endurance of the P300 512GB?

The 512 GB P300 is rated at 160 TBW (terabytes written). At a typical 20 GB per day write workload, this endurance rating would take approximately 21 years to exhaust. This is adequate for the light to moderate workloads the P300 is designed for, though it is lower than enthusiast-tier NVMe drives that often exceed 600 TBW at the same capacity.

### Is the P300 512GB compatible with laptops?

Yes. The single-sided M.2 2280 form factor with no heatsink fits in virtually any laptop with an M.2 NVMe slot. The DRAM-less E13T controller draws less power than enthusiast NVMe controllers, which is beneficial for battery life. Verify your laptop supports NVMe M.2 drives (not just SATA M.2) before purchasing.

### How does the P300 512GB compare to the Crucial P3?

Both are budget PCIe 3.0 NVMe SSDs with DRAM-less controllers and similar sequential read speeds around 2,100 MB/s. The P300 uses Phison's E13T while the Crucial P3 uses various controllers depending on revision. Real-world performance is comparable. The deciding factor is typically pricing and availability at the time of purchase.

### Is the P300 512GB good as a PS5 SSD?

No. The PS5 requires a PCIe 4.0 NVMe SSD with sequential reads of at least 5,500 MB/s recommended. The P300 is a PCIe 3.0 drive capped at 2,100 MB/s, which falls far short of Sony's requirements. PS5 owners should look at PCIe 4.0 drives like the VP4300 or Samsung 980 Pro.
