# Patriot P300 256GB PCIe 3.0 NVMe SSD (2026)

The Patriot P300 256 GB is an entry-level PCIe 3.0 NVMe SSD built around Phison's DRAM-less E13T controller, offering 2,100 MB/s reads for budget builders upgrading from SATA storage.

Quick answer: The Patriot P300 256 GB is a straightforward budget NVMe SSD that gets the job done for basic desktop use, OS boot, and light application loading at a low price point. Builders outfitting a new system on a tight budget or upgrading from a SATA SSD will see a meaningful speed improvement. Anyone doing sustained large-file writes, heavy gaming, or content creation should step up to a DRAM-equipped NVMe like the Patriot VPN100 or a higher-capacity P300 variant, since the 256 GB model has limited write performance under heavy workloads.

## Performance

Patriot rates the P300 256 GB at up to 2,100 MB/s sequential reads and up to 1,650 MB/s sequential writes, with random performance up to 290,000 read IOPS and 260,000 write IOPS. These figures are identical across all P300 capacities, which is common for DRAM-less budget drives where the controller's four channels saturate before the NAND capacity becomes a bottleneck.

In practice, the P300 256 GB delivers a clear upgrade over SATA SSDs, which max out around 550 MB/s. Against higher-end PCIe 3.0 drives with DRAM caches, the P300's random I/O performance falls behind, particularly in write-heavy workloads where the DRAM-less design and small SLC cache are limiting factors. For OS boot drive duty and light gaming, the P300 256 GB is adequate. For sustained writes of large files, the 256 GB capacity's small SLC cache will exhaust quickly and write speeds will drop to the native TLC write rate.

## Endurance, TBW & Warranty

The P300 256 GB carries an 80 TBW endurance rating within Patriot's warranty period. At a typical 10 GB per day write workload for a boot drive, the 80 TBW rating would take approximately 21 years to exhaust. Budget drives typically carry lower endurance ratings than enthusiast models, and the P300 sits at the lower end of the spectrum. The Phison E13T platform uses LDPC error correction for data integrity. Patriot backs the P300 with their standard limited warranty.

## Pros and Cons

**Pros:**

- 2,100 MB/s reads, a big step up from SATA
- Single-sided M.2 2280 fits any desktop or laptop
- Low power draw suits notebook use
- HMB support eliminates dedicated DRAM cost
**Cons:**

- 256 GB fills up quickly with modern games
- DRAM-less design limits random write performance
- Small SLC cache exhausts under sustained writes
- Low 80 TBW endurance rating
- No included heatsink or software


## Verdict

The Patriot P300 256 GB is a straightforward budget NVMe SSD that gets the job done for basic desktop use, OS boot, and light application loading at a low price point. Builders outfitting a new system on a tight budget or upgrading from a SATA SSD will see a meaningful speed improvement. Anyone doing sustained large-file writes, heavy gaming, or content creation should step up to a DRAM-equipped NVMe like the Patriot VPN100 or a higher-capacity P300 variant, since the 256 GB model has limited write performance under heavy workloads.

## Frequently Asked Questions

### Is the Patriot P300 256GB good for gaming?

It depends on the use case. For loading a few games and general desktop use, the P300 256 GB offers a clear improvement over SATA SSDs with its 2,100 MB/s reads. However, the 256 GB capacity fills up fast with modern AAA titles that often exceed 50 GB each. Gamers with larger libraries should consider the 512 GB or 1 TB variants instead.

### Does the Patriot P300 have a DRAM cache?

No. The P300 uses Phison's E13T DRAM-less controller, which relies on Host Memory Buffer (HMB) technology to borrow system RAM for flash translation table lookups. This works automatically on Windows 10 version 1709 and later. The HMB approach saves cost but delivers slightly lower random I/O performance compared to drives with dedicated DRAM caches like the Patriot VPN100 or VPR100.

### What is the TBW endurance of the P300 256GB?

The 256 GB P300 is rated at 80 TBW (terabytes written). For a boot drive with typical usage of 10 to 20 GB of writes per day, this endurance rating should last many years. Heavier workloads involving frequent large file transfers or drive cloning operations would consume the endurance rating faster. Users concerned about longevity should consider the 512 GB or 1 TB models, which carry higher TBW ratings.

### Is the P300 256GB compatible with laptops?

Yes. The P300 uses a single-sided M.2 2280 form factor with no heatsink, making it compatible with most laptops that have an M.2 NVMe slot. The DRAM-less E13T controller also draws less power than enthusiast NVMe controllers, which helps laptop battery life. Users should verify their laptop supports NVMe (not just SATA) M.2 drives before purchasing.

### How does the P300 compare to the Kingston NV2?

Both are budget PCIe 3.0 NVMe SSDs with DRAM-less controllers and similar performance targets around 2,000 MB/s reads. The P300 uses the Phison E13T while the Kingston NV2 uses various controllers depending on the batch. Performance is comparable between the two. The main differentiator is typically pricing at the time of purchase.

### Is the P300 256GB fast enough for video editing?

For basic 1080p editing with small project files, the P300 256 GB can serve as a boot drive. For serious video editing work, especially 4K timelines, the drive's DRAM-less design, small SLC cache, and limited 256 GB capacity make it a poor choice as a scratch disk. Video editors should look at drives with dedicated DRAM caches and capacities of 1 TB or more.
