## Features

- NAND module 與 CosmosPlus 的 NAND module 通用
- 可以加裝兩條 M.2 NVMe SSD
- 可以加裝兩條 DDR4 DIMM
- 可以透過設定把 DDR4 DIMMs 當成 NVMe device 使用
- 電容

Problems:

- no consolidated design (M.2 SSD + NAND + DDR4 DIMM + NVMe) yet

## Bandwidths


### NAND Module (4Ch8Way)

- Read: 332MB/s
- Write: 222MB/s

### Flash Controller

- 50MHz-100MT/s with DDR operation

### M.2 NVMe drive

- ??

### DDR4 DIMMs (configured as NVMe device)

- now configured with 800MHz-1600MT/s
- can be supported with maximum frequency, 2133MT/s.
