Samsung’s all-flash solutions for heavy workloads deliver unrivalled performance, reliability and capacity without bottlenecks.

Samsung PM1725a NVMe SSD: Fast Performance with Consistent Low Latency
Embedded with advanced flash memory, PM1725a is the optimal SSD for essential workloads, capable of huge data throughput. Its ultra-low latency and PCIe Gen3 achieve superb performance without bottlenecks. Maximum 5 DWPD top expectations for reliability and endurance.

Maximise Data Transfer with the High-Performance, Reliable PM1725a
Enterprise environments have unique requirements to ensure that they operate optimally 24/7, 365 days a year. A varied level of performance with low latency is essential. It is also critical that these environments remain stable when processing various read and write workloads. Moreover, the most crucial criteria of all are protection from data corruption or loss due to unexpected power outages. Considering each of these factors, IT and data centre managers are tasked with finding high performing, dependable memory solutions. Samsung is well-equipped to offer superb enterprise environment SSDs. The drives deliver exceptional performance in multi read applications, such as compute and virtualisation, relational databases, and storage. These high-performing SSDs also provide outstanding reliability for continual operation regardless of unanticipated power loss. Their reliability also extends to non-interrupt service in case a failure occurs on one of the paths to a port. Using its proven expertise and wealth of experience in cutting-edge SSD technology, Samsung memory solutions helps data centres operate continually at the highest performance levels. Samsung has the added advantage of being the sole manufacturer of all of its SSD components. This advantage helps ensure end-to-end integration, quality assurance and the utmost compatibility.

Optimised for enterprise environments
The Samsung PM1725a SSD is optimised to excel in virtually any data centre scenario. This enterprise-level, ultra-high performance SSD provides unsurpassed random read performance and is particularly suitable for read-intensive data centre applications. When compared with other standardised Samsung SSDs, the PM1725a SSD provides the highest random read IOPS performance. The PM1725a is equipped with Samsung 3rd-generation TLC V-NAND technology. This technology eliminates performance and reliability issues that result from capacity limitations found in planar NAND technologies. The Samsung V-NAND technology delivers reliable and consistent performance at lower costs for today's demanding data-centric world.

Superb Performance Over SAS SSDs
The PM1725a uses a state-of-the-art NVMe interface to overcome bottlenecks experienced in SAS (serial-attached SCSI) and SATA interfaces. Furthermore, the PM1725a employs the highest density to successfully process intensive and heavy enterprise workloads. When we compare the performance of a Samsung enterprise SAS SSD, which uses MLC V-NAND flash memory, to the TLC-based PM1725a, with comparable cost, the PM1725a provides up to 4.3 times more bandwidth than the MLC-based SAS SSD for sequential read and up to 5 times more IOPS for 4 KB random read.

Enterprise-Grade Power-Loss Protection
During normal power-off periods, the host server allocates time to maintain data integrity by transmitting standby commands to each device. In the event of an unexpected power loss, though, the SSD immediately uses the stored energy from tantalum capacitors to provide enough time to transfer the cached data in DRAM to the flash memory. This process helps ensure no loss of data. Power loss can occur with power outages or when users unplug devices from the system. However, the PM1725a NVMe SSD has been designed to prevent data loss with its PLP (power-loss protection) architecture. In the event of sudden power off or power failure, the PLP solution can help ensure that data issued by the host system is written to the storage media to reduce the risk of loss of data.

Dual-Port Capability
IT and data centre managers need features that can provide access to storage data without interruptions. Samsung has taken this need into consideration by including a key feature that provides access by smartly using dual-port PCIe® (PCI Express®) SSDs to get the most out of high availability. Samsung has enabled this feature in the PM1725a 2.5-inch drives, which provides the ability to create two fault domains and increases availability, providing non-interrupt service for accessing storage data. Even if a failure occurs in one of the paths to a port, preventing access along that path, the device is still accessible using the second port. The PM1725a provides virtually nonstop service with this dual-port feature support.

The PM1725a supports multiple namespaces, where a single SSD can be partitioned into multiple hardware partitions. A namespace can be assigned to multiple hosts or dedicated to a single host. The PM1725a supports up to 32 multiple namespaces.FeaturesExceptional Value
The PM1725a utilises Samsung V-NAND flash memory, which features a unique design that stacks 48 layers on top of another. It also employs cost-effective TLC (triple-level cell) flash memory, which delivers higher reliability than MLC (multi-level cell) planar NAND flash memory SSDs. With this architecture, the PM1725a can deliver enterprise-level performance economically.

Consistently High Performance
The PM1725a 2.5-inch SSD delivers a bandwidth of up to 3,300/3,000 MB/s for sequential R/W and up to 800K/160K IOPS for random 4KB R/W, respectively. The PM1725a delivers QoS (quality of service, 99%) of 160µs and 100µs for random 4KB writes.

Outstanding Reliability
Even though the PM1725a employs a TLC V-NAND flash memory, it boasts 5 DWPD (drive writes per day) for 5 years. This rate translates to writing a total of 32TB each day during that time, which means users can write 6,400 files of 5GB-equivalent data every day. This level of reliability is more than sufficient for enterprise storage systems that have to perform ultra fast transmissions of large amounts of data.

High Density
By fitting more memory into a V-NAND chip, it provides significantly more capacities of up to 6.4 TB in both the PM1725a 2.5-inch and HHHL card SSDs. Depending on your storage requirements and applications, 800GB, 1.6TB, 3.2TB and 6.4TB capacities are available.
