ThinkSystem ST50 3.5″ 5300 960GB Entry SATA 6Gb Non Hot Swap SSDNew SSDs for ThinkSystem serversDrives use Micron 96-layer 3D NAND flash memory technology with a SATA 6Gbps interfaceProvides an affordable solution for read-intensive applications such as boot, web servers, lower data rate operational databases and analyticsThe 5300 Entry SATA solid-state drives (SSDs) are new SSDs for ThinkSystem servers. The drives use Micron 96-layer 3D NAND flash memory technology with a SATA 6Gbps interface and provide an affordable solution for read-intensive applications such as boot, web servers, lower data rate operational databases and analytics.This product guide provides essential presales information to understand the 5300 Entry SSD offerings, their key features and specifications, components and options, and configuration guidelines. This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the SSDs and consider their use in IT solutions.The 5300 Entry SATA SSDs have the following features:Industry standard 2.5-inch or 3.5-inch form factors New generation 96-layer 3D TLC NAND flash memorySuitable for read-intensive workloads with an endurance of between 0.6 and 1.5 drive writes per day (DWPD) for 5 years6 Gbps SATA host interfaceHigh reliability and enhanced ruggednessMTTF of 3 million device hours – 50% more than most drivesAbsence of moving parts to reduce potential failure points in the serverS.M.A.R.T. supportAdvanced Encrypting Standard (AES) 256-bit encryptionSSDs 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. Entry SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mainstream and 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.For example, the 960 GB 5300 Entry 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. .Operating system supportSATA SSDs operate transparently to users, storage systems, applications, databases, and operating systems.Operating system support is based on the controller used to connect to the drives. Consult the controller propduct guide for more information:RAID controllers: https://lenovopress.com/servers/options/raidSAS HBAs: https://lenovopress.com/servers/options/hbaWarrantyThe 5300 Entry SATA SSDs carry a one-year, customer-replaceable unit (CRU) limited warranty. When the SSDs are installed in a supported server, these drives assume the system’s base warranty and any warranty upgrades.Solid State Memory cells have an intrinsic, finite number of program/erase cycles that each cell can incur. As a result, each solid state device has a maximum amount of program/erase cycles to which it can be subjected. The warranty for Lenovo solid state drives (SSDs) is limited to drives that have not reached the maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the SSD product. A drive that reaches this limit may fail to operate according to its Specifications.
