COLORFUL CN700 1TB M.2 NVME Gen4 Internal Solid State Drive ( SSD )

Features of COLORFUL CN700 1TB M.2 NVME Gen4 Internal

The COLORFUL CN700 1TB SSD came with a small box. There’s a window at the front to see the SSD inside. Right beside its name is a sticker indicating the drive’s capacity. From Colorful’s press release, the CN700 is available in 512GB, 1TB, and 2TB capacities. However, I don’t see a 2TB capacity of this specific model yet. Only the CN700 Pro and CN700 “War Halberd” have 2TB capacities.

Above, you can see the top and bottom views of the CN700 SSD. It’s a single-sided SSD, meaning all the components or the chips are on the (front) top side only. Most of the components are hidden behind the sticker label. Unfortunately, it’s not a heat spreader; it’s only a sticker. Let’s remove the sticker and see what’s under the hood.

The Controller and NAND Flash

The Colorful CN700 uses a controller, and NAND flash that I am unfamiliar with. The controller is MAP1602A from a company called MaxioTech. The MAP1602 is a controller specifically designed for DRAM-less SSDs. Based on its specs, the controller can support up to 7,200MB/s and 6,500MB/s of sequential read and write speeds, respectively. However, the CN700 is only rated for 5,000MB/s and 4,500MB/s of sequential read and write.

Meanwhile, this is the second time I have heard or encountered the NAND flash from YMTC. I first discovered a YMTC NAND when reviewing the . It’s a 128-layer TLC NAND flash based on YMTC’s Xtracking 2.0 cell architecture. There are four NAND flash chips on the CN700 1TB capacity.

I don’t have any more information about YMTC’s NAND flash, as the company (Yangtze Memory Technologies Co., Ltd.) was only established in 2016. Meanwhile, its controller is from (Maxiotek/Maxio Tech Corp) a spin-off company of JMicron, also established in 2016. I don’t have any further information, so let’s see how this drives performs.

Test Setup

I tested Colorful’s CN700 1TB capacity on an X670E motherboard with an AMD Ryzen 7 7700X. I installed the drive on the first M.2 slot with the motherboard’s M.2 heatsink. For presentation purposes, I removed the heatsink and took the above photo. Below are the rest of the system’s specifications:
