Samsung PM1653 960GB 2.5" SAS 24Gb/s MZILG960HCHQ-00A07 (DWPD 1) SSD

This Samsung PM1653 960GB SSD is a 2.5" SAS model aimed at server/workstation environments where stable performance and reliability are sought, rather than an inexpensive "desktop" solution. You get serious capacity from 960GB, combined with a SAS interface and read speeds up to 4200 MB/s, which is fully in tune with server workloads. Active dual-port, hardware encryption, and a whole lot of protection make it a sensible choice for environments where downtime and data loss are not an option. This is a device designed to run 24/7 in a rack, not to sit in a home office.

What you get

With read speeds up to 4200 MB/s and up to 600000 IOPS for reads, the PM1653 is convenient for mixed and read-heavy workloads such as databases, virtualization, and large file systems. Writes up to 1200 MB/s and up to 55000 IOPS for writes, plus 1 DWPD for 5 years and TBW 1752 TB, give you predictable resources for constant daily write load. V-NAND 3-bit MLC and MTBF of 2 500 000 hours show a focus on long-term operation in a data center. Active-active dual-port SAS and support for up to 32 initiators with TCQ allow this disk to enter serious SAN/NAS or clustered configurations without gasping from queue depth. Add to that Power-Loss Data Protection with aluminum electrolytic capacitors and End-to-End Data Protection, and you get an SSD that is first thought for data integrity, then for label speeds.

• Capacity from 960GB, sufficient for important databases, virtual machines, or critical applications in a server/workstation environment.
• SAS interface with active-active dual-port for high availability and operation in redundant configurations, typical for enterprise storage.
• Read speed up to 4200 MB/s and up to 600000 IOPS for reads, which helps with intensive random read workloads and fast access to large arrays of data.
• Write speed up to 1200 MB/s and up to 55000 IOPS for writes, suitable for constant transactional traffic and logs.
• Endurance from 1 DWPD for 5 years and 1752 TBW, balanced resources for read-heavy and mixed workloads without wearing out the SSD in a year.
• Reliability with MTBF 2 500 000 hours, UBER 1 sector per 10^17 bits, and data retention 3 months at end of endurance at 40°C, aimed at minimizing the risk of data loss.
• Security with AES 256-bit hardware encryption, TCG Enterprise self-encrypting drive, and support for T10 DIF and End-to-End Data Protection, important for environments with regulations and sensitive data.
• Enhanced Power-Loss Data Protection with aluminum electrolytic capacitors, which protects your writes in case of sudden power failure.
• Configurable bytes per sector: 512 / 520 / 4096 / 4160, facilitating integration with various storage controllers and software.
• Idle consumption around 5.0 W and typically 13.2 W for reads and 18.0 W for writes, which is completely normal for a SAS enterprise SSD of such a performance class.

Who it is suitable for

This SSD is aimed at admins and integrators who build or upgrade server/workstation systems with a SAS backend – file servers, virtualization hosts, databases, storage arrays. If you are chasing high availability, disk-level encryption, and stable 24/7 operation, without entering the extreme write-intensive class, the PM1653 is a logical choice. It is not suitable for a home desktop build or a gaming machine, unless you have a specific SAS infrastructure and a reason to use it there.

The combination of SAS interface, dual-port, serious IOPS for reads, and a strict package of protections and encryption makes the Samsung PM1653 960GB a highly practical tool for stable, predictable enterprise environments. If you are looking for an SSD that you can rely on for years in a server, this is exactly that type of hardware.
