Lenovo S4620 960 GB 2.5" SATA Enterprise SSD — Mixed Use Performance

Meet the Lenovo S4620 960 GB Solid State Drive, a purpose-built 2.5-inch internal SSD engineered for mixed-use server environments. This drive blends high-capacity storage, enterprise-grade endurance, and robust data protection to accelerate workloads, improve boot times, and support dense virtualization. With its SATA (SATA/600) interface, 960 GB of premium flash, and server-ready features, the S4620 is designed to deliver consistent performance under heavy I/O, while offering reliable data security in data centers, web clusters, and business-critical applications. Whether you’re refreshing an aging fleet, expanding a storage array, or building a new server rack, the Lenovo S4620 brings a balanced mix of speed, durability, and security to keep demanding workloads moving forward.

• High-capacity 960 GB 2.5-inch form factor — Ideal for dense server deployments, virtualization caches, and boot drives, the S4620 provides ample space for operating systems, applications, and frequently accessed data. The compact 2.5" size makes it easy to retrofit into standard enterprise drive cages, hot-swap trays, and servers, enabling seamless upgrades without restructuring existing hardware. With generous capacity, IT teams can consolidate workloads, reduce storage sprawl, and extend the life of legacy servers by replacing slower spinning disks with fast solid-state storage. This balance of capacity and compact form factor is particularly valuable in data centers where rack density and cooling efficiency are at a premium.
• Endurance you can trust: 4 DWPD — The S4620 is engineered for sustained write workloads, delivering a durable solution that stands up to the rigors of mixed-use operations common in servers and data-intensive environments. Four Drive Writes Per Day (DWPD) highlights the drive’s ability to handle daily data writes for the duration of its warranty period, making it suitable for workloads such as database logging, application caching, and virtualization write-heavy tasks. This level of endurance translates into lower total cost of ownership by reducing maintenance downtime and the need for frequent replacements, while maintaining consistent performance under heavy use.
• Fast, reliable performance with SATA (SATA/600) interface — The Lenovo S4620 leverages the SATA III interface (6Gb/s) to deliver a steady, dependable read throughput of up to 550 MB/s. While PCIe-based SSDs may offer higher peak speeds, enterprise SATA drives like the S4620 provide predictable performance, lower latency under mixed workloads, and broad compatibility with existing storage ecosystems. This makes the S4620 a practical choice for servers, boot volumes, databases, and caching layers where reliability and stable IO are more critical than ultra-peak sequential speed.
• Security-first design with 256-bit AES encryption — Data protection is built into the drive with hardware-based 256-bit AES encryption. This feature helps safeguard sensitive information at rest, supports compliance requirements, and simplifies key management in enterprise environments. Self-encrypting drives (SED) like the S4620 reduce the risk of data leakage in the event of drive removal or theft, and they work transparently with enterprise security policies without impacting user performance.
• Server-grade reliability and warranty — The Lenovo S4620 is designed with server deployments in mind, offering compatibility with server devices and a 1-year warranty to back up its durability. Its endurance, security features, and consistent SATA performance make it suitable for virtualized hosts, database servers, and high-availability configurations where predictable behavior and quick recovery are essential. The drive’s endurance profile and security features help IT teams meet service-level agreements (SLAs) and minimize unplanned downtime.

How to install Lenovo S4620

• Power down your server or system and unplug all cables. Ground yourself to prevent static discharge before handling the drive to protect sensitive components.
• Prepare the installation: if your server uses a 3.5" drive bay, use a compatible 2.5" to 3.5" adapter or hot-swap tray. Align the Lenovo S4620 with the mounting holes and secure it using the proper screws. Ensure the drive is firmly seated to avoid connection issues during operation.
• Connect the SATA data cable to the SATA connector on the motherboard or backplane and attach the power cable to the drive’s power interface. Verify that both connections are snug and secure to prevent intermittent connectivity or drive dropouts during I/O storms.
• Power on the system and enter the BIOS or UEFI settings. Confirm that the S4620 is detected as a storage device. If needed, enable any relevant storage configuration options (AHCI mode is typically recommended for SATA SSDs) and save the changes before exiting the BIOS.
• In the operating system, initialize and format the drive as needed. For Windows environments, use Disk Management to create a new volume and assign a drive letter. For Linux-based systems, use appropriate disk partitioning and file system creation commands. Align partitions to the drive’s native erase block size to optimize performance and longevity.
• Install or migrate your applications as required. If encryption is used, ensure key management policies are in place and that clients or services that rely on the drive can securely access the encrypted data. Regular firmware and driver updates should be applied per Lenovo’s recommendations to maintain compatibility and performance over time.
• Monitor the drive’s health and performance through your server’s monitoring tools or enterprise management software. Keep an eye on SMART attributes, throughput, and any wear indicators to proactively manage the drive’s longevity and prevent potential failures.
