Kioxia RC500 500GB NVMe SSD Review (2026)
The Kioxia RC500 500GB (originally branded as Toshiba OCZ) is a value-oriented PCIe 3.0 NVMe SSD with Toshiba TLC NAND and a DDR4 DRAM cache, offering 1,700 MB/s reads at an entry-level price.
Controller & Memory
The RC500 was originally launched under the Toshiba OCZ brand before the storage division was renamed to Kioxia. It uses a Toshiba in-house controller paired with Toshiba BiCS4 96-layer 3D TLC NAND and a DDR4 DRAM cache. The hardware foundation is solid for an entry-level NVMe drive: TLC NAND and DRAM cache provide consistent performance that QLC or DRAM-less alternatives cannot match.
The 500GB model is rated at 1,700 MB/s sequential reads and 1,600 MB/s sequential writes, with 355K random read IOPS and 410K random write IOPS. The RC500 range also includes a 1TB capacity. Unlike the newer Exceria line, the RC500 carries a shorter three-year warranty instead of five years.
The RC500 uses an M.2 2280 form factor. It targets budget builders upgrading from SATA storage who want NVMe speeds without paying the premium for higher-tier drives. The DRAM cache and TLC NAND are genuine advantages at this price point. Competitors include the Kingston A2000 500GB and the Crucial P2 500GB.

RC500 Performance & Benchmarks
The RC500 500GB is rated for 1,700 MB/s sequential reads and 1,600 MB/s sequential writes. These are entry-level PCIe 3.0 NVMe speeds — roughly three times faster than SATA SSDs (550 MB/s) in sequential reads. Random IO is rated at 355K read IOPS and 410K write IOPS, which is respectable for the price tier.

- ADATA XPG Spectrix S40G RGB 256 GB: 3,500 MB/s read, 3,000 MB/s write
- ADATA XPG Spectrix S40G RGB 512 GB: 3,500 MB/s read, 3,000 MB/s write
- Kioxia RC500 500 GB (this drive): 1,700 MB/s read, 1,600 MB/s write
The DRAM cache ensures consistent random IO performance under multitasking workloads, giving the RC500 an advantage over DRAM-less competitors. The TLC NAND maintains consistent write speeds after the SLC cache fills, avoiding the dramatic write-speed collapse that QLC drives exhibit. For OS boot, application launches, and game loading, the RC500 delivers a noticeable improvement over SATA storage. Gaming load times are faster than SATA but not as quick as 3,400 MB/s NVMe drives.

Endurance, TBW & Warranty
The Kioxia RC500 carries a three-year limited warranty — shorter than the five-year coverage on Kioxia's newer Exceria and Exceria Plus lines. Kioxia does not publish a specific TBW rating for the RC500 500GB in most documentation. The three-year warranty period is the primary coverage metric. For a budget boot drive handling mostly reads, the warranty duration should be sufficient for most users. Warranty service is handled through Kioxia's RMA process or the retailer.

Verdict: Is the RC500 Worth It in 2026?
The Kioxia RC500 500GB is a budget NVMe SSD that delivers on its core promise: 1,700 MB/s reads with TLC NAND and DRAM cache at a low price. The DRAM and TLC combination is a genuine advantage over QLC-based competitors at similar prices. The main drawbacks are the shorter three-year warranty (versus five years on most competitors) and the older product positioning — Kioxia's own Exceria line has largely superseded the RC500 with similar speeds but better warranty coverage. For the price-sensitive buyer, the RC500 is a competent NVMe upgrade from SATA. For a small price increase, the Kioxia Exceria 500GB offers the same performance with a longer warranty.
+ Pros
- 1,700 MB/s reads — three times faster than SATA
