The Kioxia Exceria NVMe drive was known as the Toshiba RC500 in a previous life but along with the re-branding, there has come a new flagship drive with a 1TB capacity, double that of the original flagship RC500. The drive uses a combination of a 4-channel in-house controller and BiCS4 96-layer 3D TLC NAND.

Performance-wise Kioxia quote Sequential read/write figures of 1,700MB/s and 1,600MB/s respectively for the 1TB Exceria NVMe. Under testing with the ATTO benchmark, we could confirm those figures with test results from the review drive of 1,630MB/s and 1,570MB/s for read and writes respectively. Using our own Sequential tests we got slightly better results. Both reads 1,780.53MB/s (QD16) and writes 1,674.91MB/s (QD16) were faster than the official figures.

Random 4K performance figures (QD32 T8) for the 1TB model are up to 350,000 IOPS for reads and up to 400,000 IOPS for writes. With our 4-threaded tests, we couldn’t get close to these figures, the best read figure we saw from our tests was 214,385 IOPS. Similarly write figures were at 117,506 IOPS (QD8), a lot lower than the official ratings. However, we did some quick tests at a QD of 32 using 8 threads and got a read figure of 414,268 IOPS and writes of 448,325 IOPS, both bettering the official ratings.

Kioxia's SSD Utility management software all the tools you need to maintain the drive as it displays lifespan, capacity usage, temperature as well as supporting firmware updates. There’s even a built-in benchmarking tool to run to see how the drive is performing.

We found the 1TB Kioxia Exceria on Span.com for £106.80 (inc VAT) HERE.

Pros

• All-round performance.
• 5-year warranty.

Cons

• Couldn’t reach the official maximum 4K figures under our testing.

KitGuru says: Kioxia have aimed the Exceria NVMe drive at a highly competitive sector of the market but have given it every chance with a pretty competitive price with the added attraction of a 5-year warranty.
