Dell 84C40 7.68TB SAS SSD

The Dell 84C40 is a 7.68TB enterprise solid-state drive built for read-intensive workloads. It uses a 12Gbps SAS interface and a 2.5-inch form factor. The drive suits database servers, virtualisation hosts and content repositories that demand high capacity and consistent read performance.

PM1643a TLC firmware update

The PM1643a controller and TLC NAND are shipped with updated firmware and full component testing. This preparation reduces deployment time and helps maintain steady read latency across the supported Dell PowerEdge platforms. No extra configuration utilities are bundled with the drive.

7.68TB read-intensive capacity

The 7.68TB capacity provides ample headroom for large read-heavy datasets such as analytics warehouses or media libraries. Write endurance is limited by the read-intensive design, so workloads with sustained heavy writes will exceed the drive's rated limits.

Highlights

  • 68 TB capacity supports large datasets
  • 12 Gbps SAS interface delivers fast data transfer
  • Read-intensive TLC design suits heavy read workloads
  • 5 inch form factor fits standard drive bays

Questions about this item

How often will the 7.68 TB TLC NAND in this PM1643a need replacement under read-intensive workloads?

Read-intensive TLC is rated for low write cycles, so the drive typically lasts the server refresh cycle without NAND replacement.

What limits sustained throughput first on the 12 Gbps SAS link?

The 12 Gbps SAS interface sets the maximum sustained bandwidth ceiling for the PM1643a.

How much heat does the 2.5-inch 7.68 TB SSD produce during all-day operation?

The 2.5-inch form factor and read-intensive firmware keep power draw low, so heat output stays minimal in a ventilated bay.
