Capacity and interface

The Samsung PM1643a MZ-ILT3T8B is a 3.84TB internal solid-state drive with a 2.5 inch form factor and a SAS 12Gb/s interface. It is built for servers and storage arrays that require high-capacity flash storage on a dual-ported SAS bus.

Included items

The drive ships without cables, mounting brackets or printed manuals. Buyers must provide their own SAS interconnect and any carrier required by the target chassis or backplane.

Interface limits

The SAS 12Gb/s link caps maximum throughput at the bus rate and does not support SATA signalling. Systems without a native SAS controller or compatible backplane cannot use this drive.

Questions about this item

What maintenance or replacement will the Samsung PM1643a 3.84TB drive need later?

The drive has no moving parts, so no mechanical maintenance is required; replacement is only needed if the flash media reaches its write endurance limit or a controller fault occurs.

What limit shows up first on the SAS 12Gb/s interface under sustained use?

The 12Gb/s SAS link sets the maximum throughput ceiling; once the queue is saturated, the interface bandwidth becomes the bottleneck before the internal flash does.

How much noise, heat or power does the 2.5" PM1643a produce running all day?

With no spinning disks the drive is silent; power draw stays at typical enterprise SSD levels and heat output is low enough for standard 2.5" bay cooling.
