SGI SSD Options

The current product portfolio breaks down as follows:

Client+
Client+ SSDs should be considered for boot drive or for other workloads without a lot of writing. However, these SSDs do have enterprise features, such as redundant flash and power loss protection. SGI cannot guarantee the longevity of an SSD without write throttling; therefore wear out due to flash exhaustion will not be covered by the warranty on drives without write throttle. The flip-side of that is that SSDs with write throttling may suffer a loss of write performance if over-used. Using the "smartctl" command and/or "smartd", users can monitor the life of their drive, to manage the drive and keep track of flash life remaining.

Enterprise
This class of SSD traditionally has higher over-provisioning to increase write performance and endurance at a cost of capacity. They also have temperature sensors to help flag environmental conditions that would affect SSD reliability.
