Dell 400-BCML 1.92 TB enterprise SSD 2.5" SAS 12Gb/s mixed use

Dell 400-BCML 1.92 TB SAS SSD

The Dell 400-BCML is a new 1.92 TB enterprise solid-state drive built for Dell PowerEdge servers and the PowerVault MD1420 storage system. It uses a 2.5 inch hot-plug form factor with a SAS 12Gb/s interface and 512e sector formatting. Mixed-use endurance of 1 DWPD and 10512 TBW suits workloads that balance reads and writes.

SAS 12Gb/s interface limits

The drive operates on a 12Gb/s SAS link, so throughput cannot exceed that bus speed regardless of the SSD's internal performance. A backplane or controller limited to 6Gb/s will halve the available bandwidth. Hot-plug capability requires a compatible drive bay and controller support; older enclosures without SAS 12Gb/s ports will restrict the drive to lower speeds.

1 DWPD mixed-use endurance

At 1 drive write per day the 1.92 TB drive is rated for 10512 TBW, making it appropriate for mixed read and write workloads such as databases or virtualization. Write-heavy applications that exceed this endurance level will wear the drive faster than rated. Buyers who need higher write endurance should select a drive with a greater DWPD rating.
