Silver 2.5 inch SAS solid state drive with model label

SAMSUNG

SAMSUNG MZILT3T8HBLS-00007 PM1643a 3.84TB SAS 12Gbps 2.5 internal SSD

SKU CH-AST9-GZFW2 MPN MZILT3T8HBLS-00007

A 3.84 TB SAS 12Gb/s 2.5-inch solid-state drive delivering 2100 MiB/s sequential read, 2000 MiB/s sequential write, 450k random read IOPS and 90k random write IOPS

  • 84 TB capacity supports large data sets
  • SAS 12Gb/s interface delivers 2100 MiB/s sequential read
  • 2000 MiB/s sequential write accelerates write-heavy workloads
  • 450k IOPS random read speeds transactional access
  • 90k IOPS random write handles mixed I/O patterns

3.84 TB SAS 12Gbps Enterprise SSD

The Samsung PM1643a provides 3.84 TB of storage in a 2.5 inch form factor with a SAS 12Gbps interface. It delivers sustained sequential reads of 2100 MiB/s and writes of 2000 MiB/s. Random 4KiB performance reaches 450k read IOPS and 90k write IOPS. This drive targets read-intensive enterprise workloads.

Server and array builders needing high-capacity

The drive suits storage arrays, content repositories and backup targets where sequential throughput and read IOPS matter. It is not for write-heavy transactional databases or low-latency caching tiers that demand higher random write endurance. Systems without SAS backplanes or controllers cannot use this drive.

No bundled accessories or software included

The product ships as a bare drive without mounting brackets, cables or management utilities. Integration relies on the host chassis and SAS infrastructure. Firmware updates and monitoring are handled through standard server management tools rather than a vendor-supplied package.

Questions sur cet article

Will this 2.5-inch SAS drive fit in a standard 2.5-inch drive bay or hot-swap tray?

Yes, the 2.5-inch form factor matches common server and storage array bays and hot-swap trays designed for 2.5-inch SAS drives.

Does the host system need a 12 Gb/s SAS controller to use this SSD?

The drive operates on a SAS 12 Gb/s interface and will negotiate down to 6 Gb/s or 3 Gb/s on older controllers, though peak throughput scales with the link speed.

What sustained throughput can I expect for sequential and random workloads?

Sequential reads reach 2100 MiB/s and writes 2000 MiB/s at 64 KiB; random 4 KiB reads hit 450k IOPS and writes 90k IOPS.
