Dell BOSS-S1 (3JT49) Designed for booting / system disks, featuring a specialized solution for Dell servers (PowerEdge) as Boot Optimized Server Storage.

Height / profile: Low-profile card
Supported drives: 2 × M.2 SATA SSDs (6 Gb/s)
Maximum number of drives: 2 (for RAID / non-RAID)
RAID configuration: The manufacturer specifies RAID 1 (mirroring) as the default option; more than 1 virtual disk cannot be created.
Non-RAID support (passthrough): Yes — drives can also be used without a RAID layer → each disk operates independently.

Disk cache / non-volatile cache: The card has no non-volatile cache or backup power battery.
TRIM support: In non-RAID mode, the TRIM command is supported (for SSDs)
