Product Details

Lenovo Solid State Drive (SSD) 200GB MLC 2.5in HS SAS G3HS ( 00AJ207, J32BK79) - New


  • Utilizes 19 nm MLC NAND technology
  • Enterprise level read and write performance
  • High endurance, with up to 29.2 PB of total bytes written (TBW) to withstand applications with intensive read/write workloads
  • Energy saving, with as little as 7 watt power consumption
  • No moving parts reduces the potential for failure
  • S.M.A.R.T. support
  • Advanced Encrypting Standard (AES) 256-bit encryption
  • FlashGuard technology extends the native endurance of commercial-grade MLC flash
  • DataGuard technology protects against data corruption and loss
  • EverGuard technology protects data in the event of unplanned power outages
  • Static wear leveling evenly distributes data across the drive
  • Bad block management replaces failed blocks with new ones from the spare pool
  • Thermal throttling to extend the life of the drive
  • Data retention management to ensure availability and integrity of stored data

The key difference between Enterprise SSDs such as the SAS MLC Enterprise SSDs and other SSDs is their endurance (or life expectancy). SSDs have a huge but finite number of program/erase (P/E) cycles, which affects how long they can perform write operations and thus their life expectancy. Enterprise SSDs have significantly better endurance but higher cost/IOPS ratio compared to Enterprise Value SSDs. SSD write endurance is typically measured by the number of program/erase cycles that the drive can incur over its lifetime, listed as 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 will not fail upon reaching the specified TBW, but at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive will reach the end-of-life point, at which time the drive will go 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 will not be exceeded prior to the required life expectancy.

For example, with SAS MLC Enterprise SSDs, the entire drive can be fully re-written up to ten times per day to meet the five-year lifetime expectation of the drive, while Enterprise Entry SSDs can sustain less than 1 full-drive write per day to provide the same five-year lifetime.
