# Kioxia Exceria 500GB NVMe SSD Review (2026)

The Kioxia Exceria 500GB is a mainstream PCIe 3.0 NVMe SSD built on Kioxia's own controller and Toshiba 96-layer TLC NAND, offering 1,700 MB/s reads and a DRAM cache at a budget-friendly price.

Quick answer: The Kioxia Exceria 500GB is a well-positioned mainstream NVMe SSD that delivers 1,700 MB/s reads with confirmed TLC NAND and a DRAM cache — features that distinguish it from QLC competitors at similar prices. The 500GB capacity is the practical minimum for a combined OS and game drive, and 200 TBW endurance provides comfortable headroom. The main trade-off is speed: the Exceria Plus delivers double the throughput for a moderate price increase. Budget builders who prioritize capacity per dollar and value TLC reliability will find the Exceria 500GB a solid choice. Those who want faster game loads should step up to the Exceria Plus or a Samsung 970 EVO Plus.

## Performance

The Exceria 500GB is rated for 1,700 MB/s sequential reads and 1,600 MB/s sequential writes, with 350K random read IOPS and 400K random write IOPS. These are entry-level PCIe 3.0 speeds — roughly three times SATA in reads but well below the 3,200+ MB/s that higher-end PCIe 3.0 drives achieve.

The SLC cache on the 500GB model absorbs roughly 15–30 GB of burst writes at full speed before folding to native TLC rates around 800–1,000 MB/s. For a boot-and-application drive that handles mostly reads, the cache is adequate. Random IO performance is consistent thanks to the DRAM cache, which gives the Exceria an advantage over DRAM-less competitors under multitasking workloads. Gaming load times are faster than SATA but not as quick as 3,400 MB/s NVMe drives.

## Endurance, TBW & Warranty

Kioxia rates the Exceria 500GB at 200 TBW with a five-year limited warranty. At a typical consumer workload of 15–30 GB per day, the endurance budget covers 18 to 36 years. The 1.5 million hour MTBF is a population-level statistic. Warranty service is handled through Kioxia's RMA process or the retailer.

## Pros and Cons

**Pros:**

- 1,700 MB/s reads — three times faster than SATA
- TLC NAND with DRAM cache at a budget price
- In-house Kioxia controller with native BiCS5 NAND
- 200 TBW endurance with 5-year warranty
- 500GB capacity for OS plus game library
**Cons:**

- 1,700 MB/s reads — entry-level NVMe speed
- Exceria Plus delivers double the speed for modest price increase
- Small SLC cache on the 500GB model
- PCIe 3.0 — surpassed by Gen4 drives
- 1,600 MB/s writes lag behind premium NVMe drives


## Verdict

The Kioxia Exceria 500GB is a well-positioned mainstream NVMe SSD that delivers 1,700 MB/s reads with confirmed TLC NAND and a DRAM cache — features that distinguish it from QLC competitors at similar prices. The 500GB capacity is the practical minimum for a combined OS and game drive, and 200 TBW endurance provides comfortable headroom. The main trade-off is speed: the Exceria Plus delivers double the throughput for a moderate price increase. Budget builders who prioritize capacity per dollar and value TLC reliability will find the Exceria 500GB a solid choice.

## Frequently Asked Questions

### Is the Kioxia Exceria 500GB good for gaming?

The Exceria 500GB delivers 1,700 MB/s reads, providing noticeably faster game load times than SATA SSDs. The 500GB capacity holds the OS plus 6–10 AAA games. The TLC NAND and DRAM cache ensure consistent performance during game installations and updates. For budget gaming builds, the Exceria is a solid choice. If gaming performance is the top priority, the Exceria Plus with 3,400 MB/s reads is worth the price increase.

### Does the Kioxia Exceria 500GB have a DRAM cache?

Yes. The Exceria includes a DDR4 DRAM cache that supports the Kioxia TC58NC1202GST controller's flash translation layer. Having DRAM at this price point is notable — many budget NVMe drives are DRAM-less and rely on Host Memory Buffer. The DRAM cache provides more consistent random IO performance, particularly under multitasking workloads.

### What is the TBW endurance of the Kioxia Exceria 500GB?

The Kioxia Exceria 500GB is rated at 200 TBW (terabytes written), covered by a five-year limited warranty. At a typical consumer workload of 15–30 GB per day, the endurance budget covers 18 to 36 years. For a read-heavy boot-and-game drive, endurance is not a practical concern.

### How does the Exceria compare to the Kingston A2000?

Both are entry-level PCIe 3.0 NVMe drives with TLC NAND and DRAM cache. The Kingston A2000 uses a Silicon Motion controller and delivers similar 2,000/1,700 MB/s speeds. The Exceria uses Kioxia's in-house controller with native BiCS5 NAND. Both are reliable TLC drives. Pricing varies by region — compare at time of purchase. The Exceria's vertical integration may offer slightly better firmware optimization.

### Is the Exceria 500GB better than QLC drives at the same price?

Yes. The Exceria uses TLC NAND, which maintains consistent write speeds after the SLC cache fills. QLC drives can drop below SATA SSD speeds (under 200 MB/s) when their cache exhausts. The Exceria's DRAM cache also gives it an advantage over DRAM-less QLC drives in random IO. At similar prices, TLC with DRAM is the better choice for any workload that involves writes.

### Does the Kioxia Exceria 500GB work in a laptop?

The Exceria uses an M.2 2280 form factor and is compatible with most laptops that have an NVMe-capable M.2 slot. Power draw is moderate, and the single-sided design fits slim laptops. Verify that the laptop supports NVMe (not SATA-only M.2) before purchasing. The 500GB capacity is a good balance for laptop upgrades.
