This Dell 9M58K-EQL 2.5 SFF drive is an enterprise-class SSD based on the industry-standard SAS interface and operates at 12-Gb/s transfer rates. SAS SSDs combine superior reliability, data integrity, and data fail recovery making them better than both SATA SSD and Value SAS SSD for applications requiring the highest performance using SAS/SATA drives. Price is higher, but if performance is a strong requirement, then standard SAS SSDs is warranted.

This 400GB SSD from Dell EqualLogic is a part of the Mix Use (MU) category of enterprise SSDs. Offering 70/30 read/write workloads with medium endurance. E-mail/messaging, OLTP, and E-commerce are example workloads.
