The GAMMIX S70 Blade comes in a small red box. Along with a picture of the drive, the front advertises a number of its key features including its 1TB capacity, PCIe 4.0 interface, 3D NAND, support for NVMe 1.4, SLC caching and optional heatsink. The back of the box provides a bit more information regarding the GAMMIX S70 Blade's features and performance. Inside, you'll find the SSD as well as a black, aluminum heatsink that can be attached to the drive.
The GAMMIX S70 Blade uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 80 x 22 x 3.3 mm and weighs in at 7g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.
Like the GAMMIX S70, the GAMMIX S70 Blade uses Innogrit's Rainier (IG5236) controller. Designed for the high-end client and entry-level datacenter markets, this PCIe Gen 4 x4 NVMe 1.4 controller has 8 NAND channels that can run at up to 1200MT/s. The GAMMIX S70 Blade also supports MLC, TLC and QLC NAND and features multiple data encryption and protection schemes including AES, ECC and end-to-end data protection.
For the 1TB version of the GAMMIX S70 Blade, ADATA has opted to use its own Micron manufactured 176-layer 3D TLC NAND flash. Looking at the picture above, you can see that there are two 256GB NAND flash packages on either side of the PCB. The drive also has a pair of 512MB Samsung DDR4 DRAM memory chips that are used for caching.
The aluminum heatsink included with the GAMMIX S70 Blade is simple, yet functional. It attaches to the top of the drive using thermal adhesive and does have a small, yet measurable, impact on temperature. I found that with the heatsink installed, the GAMMIX S70 Blade's temps dropped by a few degrees during idle periods and heavy workloads.
