Deployment / Use Cases
This SSD is engineered for server storage applications where consistent read performance and data security are priorities. The 1.92TB capacity provides substantial storage for operating systems, application files, databases, and virtual machine images in single-server or small cluster configurations.
Typical deployment scenarios include file servers, web servers, and application servers where read operations dominate the workload. The read-intensive endurance profile makes it suitable for caching layers, content delivery networks, and archival storage systems that require frequent data access with moderate write activity.
Server Storage Expansion
Add high-performance storage capacity to existing Lenovo ThinkSystem servers without requiring infrastructure changes, leveraging the hot-swappable design for easy maintenance.
Read-Intensive Workloads
Support applications with heavy read patterns including database queries, media streaming, and virtual desktop infrastructure where fast data retrieval enhances user experience.
Physical Profile
The drive measures 2.76" wide by 3.94" deep with a 7mm (0.28") height profile, fitting standard 2.5" server drive bays. At approximately 2.47 ounces (70 grams), it maintains a lightweight form factor that minimizes weight load in multi-drive server configurations. The compact dimensions ensure compatibility with rack-mounted and tower server chassis designed for 2.5" storage devices.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 0.28" (7 mm), 2.76" (70 mm), 3.94" (100 mm), 2.47 oz (70 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
What server models is this SSD compatible with?
This Lenovo 5400 PRO SSD is specifically validated for Lenovo ThinkSystem servers including the SE450 (7D8T), ST250 V2 (7D8G/7D8F), and SR250 V2 (7D7R/7D7Q) models. It uses a standard 2.5" form factor with SATA 6Gb/s interface, making it potentially compatible with other servers supporting 2.5" SATA drives, but optimal performance and reliability are guaranteed in the listed ThinkSystem configurations.
What does 1.5 DWPD endurance mean for this SSD?
DWPD stands for Drive Writes Per Day, indicating how much data can be written to the drive daily over its warranty period while maintaining reliability. The 1.5 DWPD rating means you can write 1.5 times the drive's 1.92TB capacity (approximately 2.88TB) every day for the warranty period. This translates to 5,256 TBW (Total Bytes Written) total endurance, classifying it as a read-intensive drive suitable for server workloads with more read than write operations.
How does the encryption work on this solid state drive?
The drive features 256-bit AES hardware encryption that protects data at rest without requiring software intervention or impacting performance. This enterprise-grade encryption secures all data stored on the drive, making it suitable for servers handling sensitive information. The encryption is always active and transparent to the operating system, providing security compliance for regulated industries and data-sensitive applications.
What are the performance specifications for random I/O operations?
For random 4KB operations, this SSD delivers 95,000 IOPS (Input/Output Operations Per Second) for read operations and 33,000 IOPS for write operations. These random performance metrics are particularly important for server applications where multiple small file accesses occur simultaneously, such as database transactions, virtual machine operations, and file server activities. The high read IOPS supports responsive server performance under multi-user workloads.
Can this drive be replaced while the server is running?
Yes, this SSD features hot-swappable capability, meaning it can be removed and replaced while the server remains powered on and operational. This design allows for maintenance, upgrades, or failed drive replacement without requiring server downtime. The hot-swap functionality requires a compatible server chassis with hot-swap drive bays and proper handling procedures to ensure data integrity during the replacement process.
What warranty coverage does this Lenovo SSD include?
The Lenovo 5400 PRO SSD comes with a one-year limited warranty that includes customer-replaceable unit (CRU) service. This means if the drive fails within the warranty period, Lenovo provides a replacement unit that customers can install themselves, minimizing server downtime. The warranty covers manufacturing defects and ensures the drive meets its published specifications for the duration of the coverage period.
