The Intel S4610 Mainstream SATA solid-state drives (SSDs) for Lenovo servers are advanced data center SSDs optimized for mixed read-write performance, endurance and strong data protection. Compared with the Intel S4600 series, these new drives offer improved performance and lower latency.The Intel SSD S4610 drives with 3 full drives writes per day (DWD) are an excellent choice as cache in transactional application and high-speed storage for enterprise databases.The Intel S4610 Enterprise Mainstream SATA solid-state drive is shown in the following figure.The key difference between Performance SSDs such as the S3710 SSDs, Mainstream SSDs such as the S4610 SSDs, and Entry SSDs, such as the S4510 SSDs, is their endurance (life expectancy). SSDs have a huge, but finite, number of program/erase (P/E) cycles, which determines how long the drives can perform write operations and thus their life expectancy. Mainstream SSDs have better endurance than the Entry SSDs, but at a higher cost/IOPS ratio.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 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, but 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 S4610 960 GB drive has an endurance of 6.0 PB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 3,288 GB of writes per day, which is equivalent to 3.4 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 5,479 GB of writes per day, which is equivalent to 5.7 full drive writes per day.

LTO Generation 6 tape drives feature hardware-based data encryption capabilities and support write once, read many (WORM) cartridges to help protect your data. With WORM cartridges you can store vital data in a non-erasable, non-rewritable format, while AES256 hardware encryption can securely store data to help ensure compliancy with data security, information disclosure, and privacy regulations for data at rest.This drive is compatible with the cartridges of its predecessor, the Half-High LTO Ultrium 5 Tape Drive. It can also read generation 4 cartridges.

The 12 Gb SAS HUSMM32 Enterprise Performance FIPS SED solid-state drives (SSDs) are high-performance self-encrypting drives (SEDs) that adhere to the Federal Information Processing Standard 140-2 (FIPS 140-2) cryptographic standard. These drives are available in either 2.5-inch or 3.5-inch drive form factor for System x servers.Self-encrypting drives provide the ultimate in security for data-at-rest and help reduce IT drive retirement costs in the data center. When combined with the compatible RAID controllers, SED drives in Lenovo servers deliver a cost-effective, secure solution for businesses of all sizes. Self-encrypting drives are also an excellent choice if you need to comply with government or industry rules regarding data privacy and encryption.The 12 Gb SAS Enterprise Performance FIPS SED SSD is shown in the following figure.
