KINGBANK KP260 Plus 512GB: a faster step up from the KP260 (2026)
Quick answer
The KINGBANK KP260 Plus 512GB suits value-focused buyers who want flagship-tier PCIe 4.0 speed - a fast PS5 upgrade or gaming boot drive - without paying flagship-tier prices.
Read: 7000 MB/s Write: 6500 MB/s Endurance: 600 TBW Warranty: 1 years Interface: M.2 4.0 x 4
The KINGBANK KP260 Plus 512GB is a DRAM-less PCIe 4.0 NVMe drive rated past 7,000 MB/s reads, a notable step up from KINGBANK's standard KP260 at a similar budget price.
Controller & Memory
KINGBANK builds the KP260 Plus around the same Maxio controller and YMTC TLC NAND combination as its standard KP260, again skipping a dedicated DRAM chip in favor of Host Memory Buffer, but tunes the firmware and cache behavior for a substantially higher rated sequential speed. It connects over PCIe 4.0 x4 in the standard M.2 2280 form factor.
The "Plus" naming marks this as the faster sibling of KINGBANK's base KP260, which tops out around 5,000 MB/s reads and 4,000 MB/s writes - the Plus roughly doubles the write figure while keeping the same 600 TBW endurance and 1-year warranty terms. It also ships in 1 TB and 2 TB capacities, and KINGBANK continues to sell primarily direct-to-consumer through online marketplaces rather than major Western retail chains.
Without an included heatsink, the KP260 Plus fits laptops, thin desktops, and the PS5's internal M.2 slot without clearance issues, though a desktop build under sustained heavy writes may benefit from an aftermarket M.2 heatsink given the higher rated throughput. At this speed tier it lines up against DRAM-less flagship-class drives like the Lexar NM790 and WD Black SN770, both of which carry longer independent review histories and more consistent retail warranty support overall for cautious buyers.

KP260 Plus Performance & Benchmarks
KINGBANK rates the KP260 Plus 512GB at up to 7,000 MB/s sequential reads and 6,500 MB/s sequential writes over PCIe 4.0 x4, putting it in flagship-speed territory despite the DRAM-less design. Independent aggregated benchmark data on the same drive family (1 TB unit) shows real-world measured throughput closer to 6,385 MB/s reads and 5,075 MB/s writes - lower than the rated burst figures, which is a normal gap between manufacturer-rated peaks and sustained measured performance rather than a sign of a problem.

- 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: 14,000 MB/s read, 12,000 MB/s write
- KINGBANK KP260 Plus 512 GB (this drive): 7,000 MB/s read, 6,500 MB/s write
As with the standard KP260, the Plus leans on an SLC write cache and Host Memory Buffer rather than dedicated DRAM to hit its numbers; once a large sustained transfer exhausts the cache, write speeds drop toward the native TLC ceiling. Random IOPS figures for this capacity aren't independently confirmed, so treat specific numbers seen elsewhere with caution. For gaming, OS responsiveness, and general desktop use, the KP260 Plus delivers speeds that outrun most DRAM-equipped budget drives, though buyers doing constant large sustained writes will still find more consistent behavior on a drive with dedicated DRAM.

Endurance, TBW & Warranty
KINGBANK rates the KP260 Plus 512GB at 600 TBW of total write endurance, the same figure as the slower standard KP260 despite the higher speed. At a typical 20-50 GB of writes per day, that budget lasts roughly 33 to 82 years before hitting the rated limit, far longer than most buyers will own the drive, so endurance isn't a practical concern for normal use. The MTBF rating is 2,000,000 hours, a statistical reliability figure describing failure rates across a large population of drives rather than a guarantee for any individual unit.
Warranty coverage on this listing is 1 year, notably short for a drive rated at flagship-tier speeds and shorter than the 3-to-5-year terms common among established brands. Buyers should weigh that shorter coverage window against the lower purchase price typical of KINGBANK's direct-to-consumer sales model.

Verdict: Is the KP260 Plus Worth It in 2026?
The KINGBANK KP260 Plus 512GB suits value-focused buyers who want flagship-tier PCIe 4.0 speed - a fast PS5 upgrade or gaming boot drive - without paying flagship-tier prices. It's a weaker choice for buyers who prioritize long warranty coverage or an established independent review track record, since KINGBANK's 1-year warranty trails bigger names by several years. Buyers who want similar DRAM-less speed with more warranty security should look at the Lexar NM790. Overall, the KP260 Plus 512GB is a strong price-to-performance pick for anyone comfortable trading brand recognition and warranty length for a lower price at a genuinely fast rated speed.
