122.88 TB, Samsung shows off BM1743 enterprise-class QLC SSD

According to news from this site on August 15, technology media Anandtech published a blog post on August 13, reporting that Samsung attended the FMS 2024 exhibition and demonstrated the BM1743 enterprise-class QLC solid-state drive with a capacity of up to 122.88 TB.

BM1743

Compared with the previous generation product, BM1743’s I/O performance has been improved by 4.1 times, the data retention rate has been improved, and the energy efficiency of continuous writing has increased by 45%. The official announcement of the relevant data of the 128 TB QLC solid-state drive is as follows:

Sequential read speed is 7.5 GBps

Write speed is 3 GBps

Random read IOPS is 1.6 million

16 KB random write IOPS For 45,000

PM9D3a

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.

PM1753

PM1753 is Samsung’s current enterprise-class SSD flagship product. This U.2 / E3.S SSD supports 16 NAND channels, has a capacity of up to 32 TB, and has nominal sequential read and write speeds of 14.8 GBps and 11 GBps respectively.
