Lenovo ThinkSystem 2.5″ 5400 PRO 480GB Read Intensive SATA 6Gb HS SSD – 4XB7A82259
- Storage : 480GB SSD
PN: 4XB7A82259
Overview
The ThinkSystem 5400 PRO Read Intensive SATA 6Gb SSDs are general-purpose self-encrypting SSDs (SEDs) based on the Micron 5400 PRO platform and are available in capacities ranging from 240GB to 7.86TB. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads.
Features
The 5400 PRO SSDs have the following features:
- Industry standard form factors:
- 2.5-inch with Lenovo hot-swap tray
- 2280 M.2
- Compliant with the Trusted Computing Group Enterprise Security Subsystem Class cryptographic standard (TCG Enterprise SSC)
- Supports the SafeStore self-encrypting drive (SED) functionality of ThinkSystem RAID adapters
- New generation 176-layer 3D TLC NAND flash memory
- Suitable for read-intensive workloads with an endurance of up to 1.5 full drive writes per day (DWPD) for 5 years
- 6 Gbps SATA host interface
- High reliability and enhanced ruggedness
- Absence of moving parts to reduce potential failure points in the server
- S.M.A.R.T. support
- Advanced Encrypting Standard (AES) 256-bit encryption
- Supports Sanitize Cryptographic Erase
- Full end-to-end data path protection:
- Extended error correction code (ECC)
- Exclusive-OR (XOR) parity to protect against Flash die failure
- Parity-checked internal data paths without an external write cache
- Power loss data management without the need for a supercapacitor
SSDs have a huge but finite number of program/erase (P/E) cycles, which affect how long they can perform write operations and thus their life expectancy. Read Intensive SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mixed Use SSDs. SSD write endurance is typically measured by the number of program/erase cycles that the drive can incur over its lifetime, which is listed as total bytes written (TBW) in the device specification.
The TBW value that is assigned to a solid-state device is the total bytes of written data that a drive can be guaranteed to complete. Reaching this limit does not cause the drive to immediately fail; the TBW simply denotes the maximum number of writes that can be guaranteed. A solid-state device does not fail upon reaching the specified TBW. However, at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive reaches the end-of-life point, at which time the drive goes into read-only mode. Because of such behavior, careful planning must be done to use SSDs in the application environments to ensure that the TBW of the drive is not exceeded before the required life expectancy.
For example, the 5400 PRO 960GB drive has an endurance of 2,628 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 1,440 GB of writes per day, which is equivalent to 1.5 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 2,400 GB of writes per day, which is equivalent to 2.5 full drive writes per day.
