PCIe 4.0 x4, NVMe 1.4
The Benefits of upgrading to PCIe Gen4.0 x4 SSDs
Here are 3 key benefits for those looking to upgrade their PC with PCIe 4.0 x4 SSDs.

1. Motherboard support PCIe 4.0 x4 SSD becomes mainstream
Many motherboards support the PCIe 4.0 x4 M.2 slot, from Intel Z490 to AMD X570 and beyond. With the widespread adoption of the PCIe 4.0 x4 M.2 slot in motherboards, upgrading your computer for greater efficiency has become easier. The GIGABYTE Gen4 4000E SSD is the first choice when it comes to boosting performance.

2. Improved performance for users
The performance boost offered by PCIe 4.0 x4 SSDs goes beyond gaming. For power users who are busy with data processing, file transfers and multitasking, the higher bandwidth of PCIe 4.0 significantly improves the overall performance of the PC. Whether you're managing large data sets or handling intensive tasks, PCIe 4.0 provides a smoother and more responsive user experience.

3. Faster operating system speed
The increased bandwidth of PCIe 4.0 SSDs results in a faster operating system. Expect instant boot times and fast loading of programmes when using Windows OS. This improvement in everyday usability enhances the overall user experience.
Unleash the Power of PCIe 4.0 x4 and NVMe 1.4
Boasting a PCIe 4.0 x4 interface and adhering to the NVMe 1.4 specification, GIGABYTE Gen4 4000E SSD offers a sequential read speed of up to 4,000 MB/s* and a sequential write speed of 3,900 MB/s*.

*Performance may vary depending upon drive capacity and the system hardware.
Host Memory Buffer (HMB)
The Host Memory Buffer (HMB) feature utilizes the DMA (Direct Memory Access) of PCI Express to allow SSDs to use some of the DRAM on PC system, instead of requiring the SSD to bring its own DRAM.

* HMB feature is only supported by Windows 10 & 11.
Secure Your Data
With support for TRIM, SMART and Over-Provision, GIGABYTE Gen4 4000E SSD ensures that your data is not only protected, but also optimized for stable and consistent performance over time.
SSD Tool Box
The newly updated SSD Tool Box is a software that gives users an overview of the SSD Status and various aspects such as model name, FW version, health condition and sensor temperature. Moreover, users can clear all the data with the Secure Erase function. You can download the SSD Tool Box from the link.
