# Kioxia Exceria 1TB NVMe SSD Review (2026)

The Kioxia Exceria 1TB is the range-topping capacity of Kioxia's mainstream NVMe line, offering 1,700 MB/s reads, 400 TBW endurance, and confirmed TLC NAND with DRAM cache at a budget-friendly price.

Quick answer: The Kioxia Exceria 1TB is a value-focused mainstream NVMe SSD that delivers the right features at a budget price: confirmed TLC NAND, DRAM cache, 400 TBW endurance, and enough capacity for a full system build. The 1,700/1,600 MB/s speeds are entry-level for NVMe but represent a genuine upgrade from SATA. The Exceria Plus offers double the throughput for more money. For budget builders who prioritize capacity, reliability, and consistent write performance over peak speed, the Exceria 1TB is one of the better TLC NVMe options at its price point.

## Performance

The Exceria 1TB 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 — three times faster than SATA in sequential reads. The 1TB model's larger SLC cache absorbs roughly 30–60 GB of burst writes before folding to native TLC rates around 1,000–1,200 MB/s, which is better than the smaller capacities.

The DRAM cache ensures consistent random IO performance under multitasking workloads. Gaming load times are noticeably faster than SATA SSDs, though not as quick as 3,400 MB/s NVMe drives. The 1TB capacity holds 15–25 AAA titles alongside the OS and applications, making it a practical single-drive solution for budget builds. Content creators will find the sustained write performance adequate for basic video editing, though the 1,600 MB/s ceiling is lower than enthusiast-grade NVMe drives.

## Endurance, TBW & Warranty

Kioxia rates the Exceria 1TB at 400 TBW with a five-year limited warranty. At 30–40 GB of writes per day, the endurance budget covers 27 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
- 1TB capacity for OS, games, and applications
- TLC NAND with DRAM cache at a budget price
- 400 TBW endurance with 5-year warranty
- In-house Kioxia controller with native BiCS5 NAND
**Cons:**

- 1,700 MB/s reads — entry-level NVMe speed
- Exceria Plus delivers double the speed for moderate price increase
- PCIe 3.0 — surpassed by Gen4 drives
- 1,600 MB/s writes lag behind premium NVMe drives
- Limited management software compared to Samsung or WD


## Verdict

The Kioxia Exceria 1TB is a value-focused mainstream NVMe SSD that delivers the right features at a budget price: confirmed TLC NAND, DRAM cache, 400 TBW endurance, and enough capacity for a full system build. The 1,700/1,600 MB/s speeds are entry-level for NVMe but represent a genuine upgrade from SATA. The Exceria Plus offers double the throughput for more money. For budget builders who prioritize capacity, reliability, and consistent write performance over peak speed, the Exceria 1TB is one of the better TLC NVMe options at its price point.

## Frequently Asked Questions

### Is the Kioxia Exceria 1TB good for gaming?

The Exceria 1TB delivers 1,700 MB/s reads, providing game load times that are significantly faster than SATA SSDs. The 1TB capacity holds 15–25 AAA titles alongside the OS. The TLC NAND and DRAM cache ensure consistent performance during game installations and updates. For budget gaming builds, the Exceria 1TB offers good capacity and reliable TLC performance. If maximum load speed is the priority, the Exceria Plus with 3,400 MB/s reads is worth the upgrade.

### Does the Kioxia Exceria 1TB have a DRAM cache?

Yes. The Exceria includes a DDR4 DRAM cache that assists the Kioxia TC58NC1202GST controller with flash translation layer management. The DRAM ensures consistent random IO performance under multitasking workloads, giving the Exceria an advantage over DRAM-less budget NVMe drives. This is a notable feature at the Exceria's price point.

### What is the TBW endurance of the Kioxia Exceria 1TB?

The Kioxia Exceria 1TB is rated at 400 TBW (terabytes written), covered by a five-year limited warranty. At a typical consumer workload of 30–40 GB per day, the endurance budget covers 27 to 36 years. Even at a heavy 100 GB per day, it would take 10 years to exhaust the allowance. For normal desktop and gaming use, endurance is not a practical concern.

### How does the Exceria 1TB compare to the Crucial P2 1TB?

Both are budget PCIe 3.0 NVMe drives. The Exceria uses TLC NAND with a DRAM cache, while the Crucial P2 has been known to use QLC NAND in some batches. TLC provides more consistent sustained writes than QLC. The Exceria also has DRAM, which some P2 variants lack. Peak speeds are similar. For reliability and consistent write performance, the Exceria's confirmed TLC with DRAM is the safer choice.

### Is the Exceria 1TB good for video editing?

The Exceria 1TB handles basic video editing adequately with 1,600 MB/s writes and 400 TBW endurance. The 1TB capacity provides room for project files and render caches. The TLC NAND maintains consistent write speeds during exports. However, the 1,600 MB/s write ceiling is lower than enthusiast NVMe drives (3,000+ MB/s). For casual 1080p editing, the Exceria is sufficient. For professional 4K workflows, a faster NVMe drive like the Exceria Plus would be a better investment.

### Does the Kioxia Exceria 1TB work in a laptop?

The Exceria 1TB uses an M.2 2280 form factor compatible with most laptops that have an NVMe-capable M.2 slot. Power draw is moderate for a PCIe 3.0 drive. Verify that the laptop supports NVMe (not SATA-only M.2) before purchasing. The 1TB capacity is an excellent upgrade for laptops with limited storage.
