The Lenovo 4XB7A90889 is an internal Solid-State-Drive (SSD) with a storage capacity of 960 GB and a 8,9 cm ( 3,5 inch ) form factor, specifically designed for use in servers and workstations. The device features a Serial ATA III interface, enabling a maximum data transfer rate of 6 Gbit/s. This interface is widely used in server environments and ensures reliable and fast communication with the host system. The SSD is not designed for NVMe technology, but is based on the SATA standard architecture, which is supported by many existing server platforms.

Applications

The SSD is designed as a mixed-use solution, meaning it is suitable for both read and write operations, with a focus on an average workload of one daily write cycle per day. It is therefore suitable for applications in enterprise infrastructure, data processing, and server storage systems where balanced performance and reliability are required. Use in servers and workstations is explicitly supported, ensuring compatibility with Lenovo ThinkSystem platforms and other systems with SATA 8,9 cm ( 3,5 inch ) components.

Features and Specifications in Detail

The SSD achieves a read speed of 480 MB/s and a write speed of 460 MB/s, ensuring efficient data processing in server environments. For random read operations (4KB), up to 81,000 IOPS are achieved, while for random write operations (4KB), 28,000 IOPS are possible. These values are typical for SSDs used in servers, where small, random data accesses are frequently required. The Uncorrectable Bit Error Rate (UBER) is less than 1 per 10^17 bits read, guaranteeing high data integrity. The mean time between failures (MTBF) is 2,000,000 hours, indicating high reliability and longevity.

Technology Explained Simply

The SATA III interface enables a data transfer rate of up to 6 Gbit/s, which is sufficient to fully utilize the SSD's performance. The 8,9 cm ( 3,5 inch ) form factor is the standard for internal hard drives in servers and allows for easy integration into existing systems. The SSD is not equipped with hardware encryption, meaning data encryption must be handled via software solutions or at the system level. The operating temperature ranges from 0 to 70 °C, enabling broad deployment in various environments. The storage temperature ranges from -40 to 85 °C, ensuring safe transportation and storage under extreme conditions.

Compatibility and Accessories

The SSD is specifically developed for use in servers and workstations, particularly for Lenovo ThinkSystem platforms. The designation Vendor Agnostic" indicates that the device is not tied to a specific manufacturer and can therefore be used in various systems, provided the physical and technical requirements (3.5 form factor, SATA III) are met.

Installation and Mounting

Installation takes place in a 8,9 cm ( 3,5 inch ) hard drive bay, which is standard in server and workstation chassis. The SSD is connected to the system via the SATA connector, with power supplied through the integrated SATA connector. No additional adapters or converters are required. Mounting is done using screws, which are typically included in the server chassis.

Operational Advantages

The SSD offers high reliability with an MTBF of 2,000,000 hours and high IOPS performance, especially for random read operations. The operating temperature range of 0 to 70 °C allows use in various environments, and the storage temperature range of -40 to 85 °C ensures robust handling. The SATA III interface ensures high compatibility with existing systems. The SSD is designed for an average workload of one daily write cycle per day, which is sufficient for many enterprise applications. Data integrity is secured by a UBER of less than 1 per 10^17 bits.
