Synopsis: Jon Coulter reviews the 1TB Toshiba XG3 MLC M.2 NVMe SSD, a drive that “packs a huge punch” outperforming the Samsung SM951 and 950 Pro.

Before diving into his review, TweakTown’s Jon Coulter gives some  that Toshiba first announced their XG3 series of NVMe SSDs at Flash Memory Summit in 2015 with the XG3 family of SSDs available exclusively to OEM clients in four capacities: 128GB, 256GB, 512GB, and 1024GB.

Coulter goes on to say, “Toshiba has a reputation for building SSDs that are rock solid. One of the reasons for this reputation is Toshiba's proprietary error correction technology. The XG3 employs Toshiba's proprietary Quadruple Swing-By Code (QSBC) error-correction technology, a highly efficient error correction code (ECC), which helps protect customer data from corruption, improves reliability, and extends the life of Toshiba SSDs. QSBC is rumored to be even more efficient than LDPC.”


Referencing the Samsung SM951 from an earlier review, Coulter begins his review by discussing the differences between the SM951 and the Toshiba XG3. “Obviously, the 1TB model (XG3)  is by far the most interesting of the bunch because it is double the current capacity of Samsung's competing OEM NVMe M.2 SM951 product line. The ability for consumers to order a laptop with 1TB of NVMe goodness built right in is very appealing to mobile enthusiasts and work professionals alike.“

To address the concern of power consumption within a notebook environment, Coulter notes that “Toshiba engineered the XG3 family of SSDs for power efficiency, through lower power state modes and the use of components engineered for power efficiency.”

When compared with the competition, the XG3 did nothing but impress as Coulter points out, “It has far better sequential write performance than Intel's 750 series, and better random 4K QD4 & QD32 write performance than the Samsung offerings” and in terms of total latency, “the XG3 really delivers”. Something he reiterated after further testing, “The XG3 outperforms both the SM951 and the 950 Pro. This is a very good indicator that the XG3 can deliver better heavy workload performance in certain scenarios than Samsung's M.2 NVMe SSDs”

Coulter also mentions that Toshiba’s advertised sequential specifications for the XG3 offer read speeds up to 2516MB/s and write up to 1572MB/s. However, when tested by TweakTown, sequential transfers maxed out at an impressive 2,697MB/s read and 1644 MB/s write on an OS volume filled to 75% of its total capacity, confirming their suspicion that “the XG3 is an absolute beast in terms of performance.“

Final Thoughts

TweakTown Editor's Choice Award

In a list of pros and cons, TweakTown listed that the performance, capability, build quality, and the most appealing form factor were all strong “pros” for the product, while the only “con” was the availability of the product to consumers.

Coulter summarized, “our user experience while running the XG3 as our OS disk was outstanding. The 1TB XG3 is notably snappier than Intel's 750 series SSDs. Boot times are second only to the 950 Pro, and once inside the OS, there is no way to tell the difference between it and Samsung's M.2 NVMe SSDs.

He concludes, “Toshiba's 1TB XG3 M.2 NVMe SSD delivers performance that rivals the Samsung SM951 and 950 Pro drives with double the capacity...Overall, we feel that a 1TB NVMe M.2 SSD with the performance that the XG3 can deliver is the most appealing consumer-based SSD ever made.”

The Toshiba 1TB XG3 M.2 NVMe SSD is TweakTown recommended with a 96% overall rating, earning the TweakTown Editor's Choice Award.
