SAMSUNG PM1633a MZILS7T6HMLS-000D4 7.68 TB SAS 12Gb/s 2.5 internal SSD

SKU CH-KJ9X-Y0GKS

A 7.68 TB SAS internal SSD rated for 1 DWPD with 1,250 MB/s sequential read and write speeds

  • High-capacity 7.68 TB storage for large datasets
  • SAS 12Gb/s interface enables fast 1250 MB/s sequential reads
  • Read-intensive endurance rated at 1 DWPD for steady workloads
  • 200K IOPS random write performance handles heavy write streams
  • 5-inch form factor fits standard drive bays

Capacity and interface

The Samsung PM1633a is a 7.68 TB SAS 12Gb/s internal solid-state drive built for read-intensive workloads. It suits data-centre servers and storage arrays that need high-capacity flash with consistent sequential throughput.

Compatibility checks

Verify that your system provides a 2.5-inch bay and a SAS 12Gb/s backplane or controller; the drive uses a single SAS interface and measures 70 x 100 x 15 mm. Confirm the chassis can supply adequate airflow for a 140-gram unit and that your firmware supports 1 DWPD endurance.

Thermals noise and power

With no moving parts the SSD runs silently and generates minimal heat under normal read-intensive operation. Sequential read and write speeds reach 1250 MB/s while random 4 KB performance delivers 35k IOPS read and 200k IOPS write within the rated 2,000,000-hour MTBF.

Questions about this item

Does the drive ship with a tray, cables or screws, or must those be purchased separately?

The listing shows the drive only. A 2.5-inch SAS tray and SAS data or power cables are not included and must be sourced separately for your server or enclosure.

Should I choose the 7.68 TB model or a smaller capacity for a read-intensive workload?

The 7.68 TB model delivers 1 DWPD and 1,250 MB/s sequential throughput. Select it when you need maximum capacity at that endurance level; pick a smaller capacity only if your dataset fits and you want lower cost per drive.

What does the 1,250 MB/s sequential read figure mean once the drive is installed in a server?

In a SAS 12 Gb/s backplane the drive can sustain up to 1,250 MB/s sequential reads and writes, with 35 k random read IOPS and 200 k random write IOPS at 4 KB block size.
