| Marketing Description |
The ThinkSystem S4520 Read Intensive SATA SSDs use 144-layer Intel 3D NAND TLC Flash Memory technology with a 6Gbps SATA interface to provide an affordable solution with outstanding performance.
Compared with the S4510 series, these Read Intensive (Entry) drives offer improved endurance. The S4520 SSDs are optimized for read-intensive applications such as boot, web servers, lower data rate operational databases and analytics. |
| Product Features |
-
Enhanced durability
Built to withstand extreme conditions, this solid state drive features shock acceleration operating at 1000 g and non-operating at 1000 g, alongside vibration tolerance for both operating and non-operating states. Its robust design ensures data integrity and drive longevity, making it a reliable choice for demanding environments.
-
High performance
With 4KB random read IOPS of 90,000 and write IOPS of 43,000, coupled with an internal data rate of 550 MBps (read) and 510 MBps (write), this drive delivers swift and efficient performance. The integration of 3D NAND technology and enhanced power loss protection further optimizes speed and data security.
-
Advanced security
Equipped with 256-bit AES hardware encryption, the drive offers reliable data protection. This feature, combined with end-to-end data protection and enhanced power loss protection, provides a secure environment for your data against unauthorized access and data loss incidents.
