Last year,
Intel updated its line-up of
NVMe, PCI Express-based solid state drives, for cloud and data center applications, with a couple of different models tuned for different workloads. The Intel
SSD DC P4600 we will be showing you here was among those drives. It features a fourth-generation Intel controller and performance-optimized firmware, along with 3D TLC NAND flash memory (384Gb per die). If you remember,
the DC P3700 we looked at a few years back had an 18-channel controller and MLC NAND, so the P4600 may sound like a downgrade in some respects, but as you’ll see a little later, performance is still strong with
this newer drive relative to its predecessor.
We’ve got the Intel SSD DC P4600’s main features and specifications outlined in the table below, along with a quick tour of the and-in card. Take a peek at the specifics and
then we’ll dive in and see how the drive performs with a variety of benchmarks...

The top of the line DC P4600 series is rated for up to 702K/257K 4K random read/write IOPs, with sequential reads/writes topping out at up to 3.2GB/s and 2.1GB/s, respectively. Endurance is rated for up to 2.9 drive writes per day for five years, or 21.7 PBW (petabytes written) with a random/JEDEC workload.
The particular drive we’ll be showing you here is a
2TB Intel SSD DC P4600. The drive features the aforementioned 12-channel Intel NVMe controller, paired to IMFT 3D TLC NAND flash memory. The drive is outfitted with a PCIe x4 electrical interface (max bandwidth up to 4GB/s) and it has a half-height form factor, though U.2 based models are also available.
The Intel controller used
on these drives in an 12-channel design. This particular 2TB drive is outfitted with 24 NAND packages (12 front, 12 rear), along with some DRAM cache. There are also an array capacitors on the PCB, which provide some measure of power-loss protection.
The Intel SSD DC P4600 is also outfitted with a large heatsink that covers the controller and all of the front-mounted
NAND, but we found it hardly got warm to the touch, even after hours of testing. Unlike some previous PCIe-based enterprise SSDs we’ve looked at, which necessitated a robust cooling solution, the Intel SSD DC P4600 should be fine as long as there is moderate air-flow through the system.
Read/Write Power is rated for 9.9W / 20.7W and the drives carry a 5-year warranty. Let's setup and test...
