The Apacer AS2280P4U Pro is a solid-state drive in the M.2 2280 form factor, launched on April 10th, 2021. It is available in capacities ranging from 256 GB to 2 TB. This page reports specifications for the 256 GB variant. With the rest of the system, the Apacer AS2280P4U Pro interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the PS5012-E12S-32 from Phison. Apacer has installed TLC NAND flash on the AS2280P4U Pro, the flash chips are made by Unknown. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The AS2280P4U Pro is rated for sequential read speeds of up to 3,500 MB/s and 1,200 MB/s write; random IOPS reach up to 210K for reads and 315K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Apacer guarantees an endurance rating of 170 TBW, a typical value for consumer SSDs.

Notes

Controller:

2 main cores using Cortex-R5 clocked at 667 MHz with CoXProcessor technology (one additional dual-core) Cortex-R5 clocked at a lower clock for better efficience. The difference between this revision and the E12 revision is that this has a nichel IHS to improve the temperature, a smaller size, smaller node (12nm TSMC FinFET) and this works with less DRAM capacity.
