Gigabyte M.2 SSD 1TB NVMe 1.4 (GM21TB)

Gigabyte M.2 SSD 1TB NVMe 1.4 (GM21TB)

All-Round SSD
GIGABYTE M.2 SSD adopts Phison's E15T controller and 3D NAND flash, delivers up to 3400 MB/s sequential reads and 3200 MB/s sequential write performance. By utilizing Host Memory Buffer technology, the SSD controller can access the host DRAM without performance loss.

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.

Power Saving While Operating
Comparing with regular PCIe 3.0 x4 SSD, GIGABYTE M.2 SSD reduces about 30% power while operating. Power consumption of the GIGABYTE M.2 SSD is notably improved.

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.

Warranty
1. Limited 5-years or 600TBW.
2. Limited warranty based on 5 years or 600TBW, whichever comes first. (*TBW is evaluated by JEDEC workload standard. )
*TBW (Terabyte Written): Terabytes Written is the total amount of data that can be written into a SSD before it is likely to fail.
3. When the usage of an NVME SSD as indicated by the "Percentage Used" (SMART ID: 05) in SMART page of "GIGABYTE SSD toolbox" reaches 100 means out of warranty. (A new unused product will show the number of 0)
