P420m Overview
The P420m SSD conforms to the PCIe Card Electromechanical (CEM) specification ver-
sion 2.0, section 6.1 (low profile add-in card size). This is also called the half-height,
half-length (HHHL) form factor.
The P420m HHHL drive is available in two capacities: 700GB and 1.4TB. Both options
have the same HHHL form factor and support a x8 link width PCIe Gen2-compatible
motherboard slot.

A total of 64 NAND placements are on the drive. The 700GB drive has four NAND die
per package and the 1.4TB drive has eight NAND die per package. NAND are placed on
both the component and solder sides of the drive along with the component and solder
sides of two daughter boards, as shown in Figure 1 and Figure 2.
Figure 1 shows the drive’s LEDs. The state of these LEDs, such as color and blinking pat-
tern, convey information about the drive’s status and behavior. See Table 2 (page 50)
for LED descriptions.
