The official announcement of the relevant data of the 128 TB QLC solid-state drive is as follows:

Samsung also shared the PM9D3a 8-channel Gen 5 SSD at the exhibition, mainly for data centers:

Serial read speed up to 12 GBps

Write speed up to 6.8 GBps

Random read speed is 2 million IOPS

Random write speed is 400,000 IOPS

The hard drive is available in a variety of specifications, with a maximum capacity of 32 TB (M.2 has a maximum capacity of 2 TB). The firmware includes optional support for Flexible Data Placement (FDP) to help resolve write amplification issues.

Note from this site: Write amplification is an undesirable phenomenon in flash memory and solid-state drives, that is, the actual amount of physical data written is many times the amount of written data. Because flash memory must be erased before data can be rewritten, and erase operations are much coarser-grained than write operations, performing these operations moves user data and metadata multiple times.
