ThinkSystem 5200 Mainstream SATA 6Gb SSDs

Product Guide

The ThinkSystem 5200 Mainstream SATA 6Gb solid-state drives (SSDs) use Micron NAND flash memory technology with a SATA 6Gbps interface. They provide an affordable solution for mixed read/write applications such as excellent choice as cache in transactional application and high-speed storage for enterprise databases.

The 5200 Mainstream SATA SSD is shown in the following figure.

Did you know?

Lenovo also offers high-performance self-encrypting drives (SEDs) in the 5200 Series. These SSDs adhere to the Federal Information Processing Standard 140-2 (FIPS 140-2) cryptographic standard. Read about them in the ThinkSystem 5200 Entry SATA 6Gb SED SSD product guide .

Rigorous testing of the 5200 Series SSDs by Lenovo through the ServerProven program assures a high degree of storage subsystem compatibility and reliability. Providing additional peace of mind, these drives are covered under Lenovo warranty.

Features

The 5200 Mainstream SATA SSDs have the following features:

Industry standard 2.5-inch or 3.5-inch form factors

Innovative 64-layer triple-level cell (TLC) 3D NAND technology

Suitable for mixed read/write workloads with an endurance of between 2.5 and 5 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

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. Mainstream SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Performance 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.

ThinkSystem 5200 Mainstream SATA 6Gb SSDs 2

For example, the 5200 Mainstream drive in a 960 GB capacity has an endurance of 8.7 PB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 4,800 GB of writes per day, which is equivalent to 5.0 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 8,000 GB of writes per day, which is equivalent to 8.3 full drive writes per day.

Technical specifications

The following table presents technical specifications for the 5200 Mainstream SATA SSDs.

Tip: Drives listed in this product guide with the exception of the 3.84 TB drive are the Lenovo versions of the Micron 5200 MAX family of SSDs. The 3.84 TB drive is the Lenovo version of the Micron 5200 PRO SSD.
