The MiWhole CT300 is a solid-state drive in the M.2 2280 form factor, launched in 2022. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 512 GB variant. With the rest of the system, the MiWhole CT300 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the MAP1602A Falcon Lite from MaxioTech, a DRAM cache is not available. MiWhole has installed 232-layer TLC NAND flash on the CT300, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 80 GB, once it is full, writes complete at 900 MB/s. Copying data out of the SLC cache (folding) completes at 415 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The CT300 is rated for sequential read speeds of up to 7,500 MB/s and 6,500 MB/s write.
At its launch, the SSD was priced at 33 USD. The warranty length is set to five years, which is an excellent warranty period. MiWhole guarantees an endurance rating of 900 TBW, a good value.
