Dell Precision T3620 - Upgrade From 1 to 4 Hard Drives

Precision Tower 3620

The Precision tower 3620 base configuration has a single hard disk drive (HDD) or solid state drive (SSD) and an optical disk drive (ODD). The system has a total of 4 SATA ports for the controller allowing support for a total of 4 internal SATA drives.

This will allow a configuration of 3 HDD / SSDs and an optical drive or a 4 HDD/SSD configuration without an internal optical drive.

What do I need to upgrade to a 4 drive configuration?

The additional parts that are needed to convert the system from a single hard drive to 4 hard drives are as follows:

  • Quantity 4 2.5 in Solid Start or Hard Disk SATA 3 drives of your choice
  • Dell Part: P876J - screw that holds HDD to R494D. Quantity x 4 screws (per drive) 16 total for 4 drives
  • Dell Part: 16VP1 ASSY,CBL,SATA,ST,280MM, quantity x3 (System shipped with 1) (Figure 1)
