SSD Hard Drives

Samsung PM9A3 NVMe U.2 SSD 1.9TB 2.5'' PCI Express 4.0

Key features:

  • PCIe Gen4 x4
  • Read speed 6800 MB/s
  • Write speed 2700 MB/s
See full description

  • Communication Protocol

    Most SSDs use SATA III or PCI Express.

    Almost all 2.5" SSDs connect via SATA III while most M.2 SSDs connect via PCI Express.


    PCI Express connection offers higher speeds, but this is mainly noticeable in demanding applications (high-resolution video processing, transferring large files, etc.) and is not necessary for everyday use.

  • Write Speed

    Indicative size for the maximum speed of the hard disk during data recording. The larger the size, the faster the data recording.

    For an SSD that uses the SATA III protocol, the average recording speed is 300MB/s, while for one with NVMe it is 1200MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

  • Read Speed

    Indicative size for the maximum speed of the hard disk during data reading. The larger the size, the faster the data reading speed.

    An average reading speed for an SSD using the SATA III protocol is 600MB/s, while for one with NVMe it is 2000MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

Description

Description

The Samsung PM9A3 NVMe U.2 SSD 1.9TB 2.5’’ PCI Express 4.0 is an SSD primarily aimed at businesses and users seeking high performance and reliability. With support for PCIe 4.0 technology, it offers exceptional read and write speeds.

It is ideal for applications that require large capacity and fast data access, such as databases, cloud computing applications, and applications that demand high I/O.

Additionally, the Samsung PM9A3 NVMe U.2 SSD 1.9TB 2.5’’ PCI Express 4.0 is designed to provide high performance, reliability, and data security for server applications.

Improved speed and reliability

The PM9A3 is the solution for achieving high responsiveness in data centers that require accelerated performance. Available in capacities of 960GB, 1.92TB, 3.84TB, and 7.68TB, the PM9A3 allows your business to excel in managing big data.

Seamless, powerful performance

Get fast results with the next-generation NVMe® interface. Sequential read/write speeds of up to 6,900/4,100 MB/s, random read/write speeds of up to 1100K/200K IOPS, and an excellent level of QoS (quality of service) allow for real-time big data analysis.

Secure critical data

Data integrity is vital for the data center SSD. The PM9A3 NVMe® U.2 is protected with end-to-end data protection to ensure consistency throughout the entire data transfer path and prevents data corruption in the event of a power outage with power loss protection.

Enhanced Operational Efficiency

Achieve much more with less. Attain higher efficiency and performance compared to older storage systems, with fewer servers, reduced power and cooling, and lower TCO, all with effective management from the advanced Samsung SSD Toolkit software.

Reliability and quality of Samsung

Enjoy superior quality and reliability of SSDs produced in-house using components manufactured by Samsung. Empower your business 24/7 to operate faster, more efficiently, and at reduced costs with world-class reliability with a limited 5-year warranty or 1.0 DWPD.
