Lenovo 4XB7A80319 sisäinen SSD-kiintolevy 1,92 TB 2,5" SAS V-NAND TLC

The Lenovo 4XB7A80319 is a 1.92 TB 2.5" SAS read-intensive SSD designed for ThinkSystem servers and enterprise workstations. It uses a 24 Gb/s SAS interface and V-NAND TLC technology to provide higher sustained read performance and improved reliability compared with 6 Gb/s SATA drives. The drive supports self-encryption (SED) and enterprise-level error recovery, and is intended for workloads that require fast access to predominantly read data.

Advantages

The 24 Gb/s SAS interface supports full-duplex data transfer for higher throughput and enterprise-class error recovery for better availability. V-NAND TLC and Samsung NAND management deliver increased endurance—up to 1 drive write per day (DWPD) for five years—for read-intensive enterprise applications. Self-encrypting features provide on-the-fly encryption with no performance impact, instant secure erase capability, and auto-locking to protect data if a drive is removed or stolen.

Suitable for

• Enterprise read-intensive workloads (e.g., large-scale read caching, content delivery)
• Server and storage arrays in Lenovo ThinkSystem environments
• Applications requiring on-drive encryption and secure erase

How to use

Install the 2.5" SSD into a compatible SAS bay or drive tray in a Lenovo ThinkSystem server or other supported chassis, connect to a 24 Gb/s SAS controller, and configure the drive in the system BIOS or storage controller firmware. Enable SED features through your platform or controller management tools if encryption is required. Use the operating system and storage management software to partition, format, and place data according to your workload and redundancy policy.

Recommendations

Use this read-intensive SAS SSD in server roles where read throughput and data protection are priorities. For mixed or write-heavy workloads, evaluate endurance requirements against the specified DWPD rating and consider drives optimized for higher write endurance. Ensure regular firmware updates and follow Lenovo/ThinkSystem guidance for optimal compatibility and error recovery configuration.
