Crucial P1 1TB Type 2280 SSD Review

Storage/SSD by stefan @ 2019-07-24

The 1TB version of the P1 NVMe SSD definitely offers more performance versus the 500GB model, and can keep the write speeds up for even longer, thanks to more SLC buffer (12GB versus 5GB on the 500GB drive). The increased DDR3 buffer also seems to come into play but expect a visible speed drop when writing large files to the drive. If the drive is operated in mainstream, home computers you won’t observe this limitation, but in production workstations were data changes frequently, the TLC write speed limitation will become more evident.

Packaging, A Closer Look

After taking a look at the 500GB P1 SSD from Crucial back in December of 2018, it is time to check out the 1TB version of the drive, which is advertised as having a noticeable better performance. The packaging of the drive did remain the same, with the cardboard external enclosure, that shows the total drive capacity and the interface it operates on:

On the back side of the box, we will get to see some product highlights such as the offered data transfer software, the enclosed installation guide but also the upgradeable firmware. The product is also backed up by a 5-year warranty:

Inside the box we will get to see the advertised Quick Installation Guide, but also a transparent plastic mold, which holds the drive protected during transit:

The small guide is pretty straight forward, since most of the resources are available online anyway:

P1 comes with the usual M.2 2280 drive format, while on the front we can spot a sticker with the product code name, its power rating, the serial number but also the currently installed firmware:

On the back side there aren’t any more components, but only placeholders for two more NAND ICs and a RAM cache:

After carefully removing the sticker, we can take a look at the drive internals:

The drive comes with two Micron 64-layer 3D QLC NAND packages, each having 512GB of raw storage:

Next to it, we do have a Micron 1GB DDR3 IC:

The Silicon Motion SM2263ENG controller is a four-channel part that supports the NVMe 1.3 standard, together with full drive encryption (TCG Opal, AES):

When the drive is accessed, a green SMD LED will also blink on the drive PCB:
