Due to the potential damage that could be caused by removing the DC P3520's heat sink, we will not be doing so. We do know what is under the heat sink, so we will tell you. There are an additional 18 flash packages and three 512MB DRAM packages (one is dedicated for ECC) and of course the 18-channel Intel controller.
The drive ships in basic cardboard packaging.
Inside the cardboard packaging, the SSD is protected from shipping damage by a heavy-duty plastic clamshell container. A half-height bracket is included but not pictured.
The controller side of the PCB is covered by a full-length aluminum heat sink. Looking at the top left, we can see two large capacitors that provide host power-loss protection for data in flight.
The bottom half of the PCB has no shielding; the components are exposed. This half of the PCB houses 18 of the drive's 36 Intel 3D flash packages and two of the drive's five 512MB Micron DRAM cache packages. Four DRAM packages are dedicated for block placement and wear leveling data. The fifth DRAM package is dedicated for ECC further guaranteeing data integrity.
A view from the edge connector side of the drive.
There is a manufacturer label located on the top edge of the heat sink.
Specifications and Features
We are going to go over the 2TB DC P3520's specifications, for other capacities please refer to the above mfg. spec sheet. Intel's DC P3520 2TB Enterprise PCIe NVMe SSD comes in a half-height, half-length, low-profile Add-in Card (AIC) form factor as well as a 2.5" U.2 (SFF-8639) variant. Factory performance specifications for both form factors are identical. The 2TB AIC requires 300 LFM airflow towards the IO bracket. The 2.5" model requires 650 LFM airflow towards the connector.
Features include a PCIe Gen 3.0 x4 interface, Intel 18-channel NVMe controller, and IMFT 3D NAND flash memory. End-to-End data protection featuring XOR parity and advanced LDPC bit correction on all internal and external memories in the data path for protection at every layer.
