Rectangular E1.S SSD with silver label, 33.6 by 118.75 by 9.5 mm

SAMSUNG

SAMSUNG MZ-TL23T8A PM9A3 3.84TB E1.S PCIe Gen 4x4 internal SSD

SKU CH-Z1YE-TMJST MPN MZ-TL23T8A

A 3.84 TB E1.S internal SSD with 6800 MB/s sequential read and 4000 MB/s sequential write

  • 84 TB capacity supports large enterprise workloads
  • Sequential read up to 6800 MB/s accelerates data access
  • Random read 1,000,000 IOPS handles heavy queue depths
  • 128-layer V-NAND TLC enables high density and endurance
  • E1.S 9.5 mm form factor fits dense server chassis

Enterprise E1.S capacity

The Samsung PM9A3 MZ-TL23T8A is a 3.84 TB internal solid-state drive built for servers and storage arrays that use the E1.S form factor. It connects through a PCIe Gen 4 x4 interface and uses Samsung 128-layer V-NAND TLC flash.

Suited for high-density read-heavy workloads

This drive fits systems designed for the E1.S 9.5 mm height and 118.75 mm length with a 33.6 mm width. Builders using U.2, M.2 or taller E1.S bays cannot install it without an adapter or a different chassis.

Sequential read reaches 6800 MB/s

That throughput supports fast data ingest and analytics pipelines. Random read hits 1,000,000 IOPS while random write reaches 190,000 IOPS, and the drive draws 11 W reading and 13.5 W writing with a 2,000,000-hour MTBF.

Questions about this item

Does the E1.S form factor fit a standard M.2 slot?

No, this drive uses the E1.S form factor measuring 33.6 x 118.75 x 9.5 mm and requires a compatible E1.S bay or adapter; it will not fit an M.2 slot.

What power budget should I plan for this 3.84 TB drive?

The drive draws 11 W during sequential reads and 13.5 W during sequential writes, so ensure your backplane and cooling can sustain at least 13.5 W per drive.

What sustained write throughput can I expect in a PCIe Gen 4 x4 server?

Sequential write speed is rated at 4000 MB/s and random write at 190000 IOPS when connected to a PCIe Gen 4 x4 interface.
