Toshiba released a new BG4 series SSD at CES this year, with a maximum storage capacity of 1TB. The BG4 1TB NVMe SSD uses 96-layer BiCS 4 NAND flash memory with a read speed of 2.3GB/s and a write speed of 1.8GB/s. This article will tell more details about BG4 1TB SSD.

Nowadays, people are increasingly demanding the use of computer storage devices. Whether it is a PC desktop or a notebook computer, SSD is already an inaccessible storage device. Users not only want high-speed data transmission efficiency, but also storage. The capacity of the device should be as large as possible.

The BG4 1TB NVMe SSD uses the fourth-generation single-chip ball array package (BGA) SSD solid-state drive product, which can meet the needs of users to a large extent.

Introduction of BG4 1TB NVMe SSD

First, the BG4 series SSD uses 96-layer 3D BiCS TLC NAND flash memory chips instead of the 64 layers you are relatively familiar with. The use of such a memory chip not only brings about an increase in overall capacity, but also a reduction control of about 20% in the power consumption portion.

What’s more, Toshiba BG4 1TB NVMe SSD is only 30mm long and weights 26g. It is a M.2 2230-S3 form factor SSD with a PCIe Base Specification Revision 3.1a (NVMe Revision 1.3b) interface, which has greater data throughput.

Its sequential read speed is up to 2300MB/s and sequential write speed can reach 1800MB/s. In addition, random read speeds of up to 390K IOPS and random write speeds of up to 190K IOPS. Its effective power consumption is up to 3.7W, which has little difference from BG4 256GB SSD.

Performance of Toshiba BG4 1TB NVMe SSD


Test the SATA of the Toshiba BG4 1TB NVMe SSD using the Dell H730PRAID card inside the Dell PowerEdge R740xd server. Set the card to HBA mode to avoid the effects of RAID card caching.

This approach focuses on drive latency across the whole load range of the drive, not just the minimum QD1 levels, ensuring full capture of the end-user workload profiles. This method also reflects the end-user process with the scalability, flexibility, and compliance testing provided by the virtualization server.

Houdini by SideFX

Houdini by SideFX is a piece of software designed to evaluate the storage performance associated with CGI rendering. The test bench for this application is a variant of the Dell PowerEdge R740xd server type with dual Intel 6130 CPUs and 64GB DRAM. So Ubuntu Desktop running bare metal is installed so that the benchmark output can be completed in seconds or less.

The Maelstrom demo is part of the rendering pipeline that demonstrates storage performance by showing its ability to effectively use swap files as an extended form of memory. In order to isolate the effects of latency and wall-time on the underlying storage components, this test does not write result data or processing points. This test consists of five phases, three of which are run as part of the benchmark.

As you can see from the picture below, Toshiba performed very well in the Houdini test, scoring 2,624 seconds near the top of the non-Optane drives.

Bottom Line

The Toshiba BG4 1TB SSD is small in size but has a capacity of 1TB and also supports the SED model that provides TCG Opal version 2.01. It is ideal for portable PCs with exceptional performance.
