Toshiba KBG40ZNS1T02 Kioxia BG4 1TB Solid State Drive Review
Built for Speedy Application Performance
This Toshiba KBG40ZNS1T02 Kioxia BG4 1TB SSD is built for a variety of applications such as mobile, IoT devices, and server boot. BG4 stands for the fourth generation of the company’s ball grid array (BGA) SSD product line. These new SSDs come in the tiny M.2 2230 form factor making them ideal for ultra-mobile PCs, 2-in-1 notebook PCs, IoT/embedded devices, and server and storage array boot drives.
The Kioxia BG4 solid state drive leverages Toshiba’s 96-Layer BiCS FLASH to hit quoted speeds of up to 2.3GB/s read and 1.8GB/s write as well as throughput as high as 390K IOPS read and 200K IOPS write. Not too shabby for something slightly larger than an SD card. The BG4 is able to hit these numbers while only using 3.7W of power.
Toshiba BG4 NVMe SSD Design and Build
The KBG40ZNS1T02 Toshiba BG4 is a very small SSD with a single NAND pack on one side and blank on the other. The drive itself is smaller than a standard SD. The BG4 had SQL Server performance of 2,568.4 TPS with an average latency of 1,099ms.
BG4 SSDs deliver best-in-class read performance in single package SSDs, of up to 2,000MB/s (sequential read) and up to 390K IOPS (random read), with active power consumption of up to 3.7W (Typ.). The drive is also offered in an SED model supporting TCG Opal Version 2.01.
