The tested unit then, you should easily be able to place the M.2 unit into a compatible NVMe protocol motherboard. Most motherboard chipsets support it. You should, however, check out with the motherboard manufacturer if you have an x4 lane PCIe Gen 3.0 / 4.0 version with NVMe protocol support.

We have a 1TB, and 2TB Solidigm P44 Pro is available. The SSD uses a PCB layout with only one side. Front labels feature the Solidigm logo and model information, while back labels specify the country of origin, SN code, and PN code. Single-sided SSDs are slimmer than double-sided SSDs and can store the same amount of data. Regarding desktop computers, the thickness of an M.2 SSD often is not an issue, but it is a significant concern for laptops. Most laptops do not allow for the installation of double-sided solid-state drives.

The compact M.2 2280 form factor ensures compatibility with the next-generation desktop and mobile platforms that support the M.2 PCIe slot and interface. The 80 on 2280 is short for 80mm, aka, that is the length of the card, and 2280, you guessed it now .. 22mm for its width. The heatsink does raise a new concern; it's higher. Very low PCIe devices could be blocked, albeit there was enough clearance for graphics cards that we quickly inserted to check out.

The SSD's primary chips are its master controller, DRAM cache, and two flash memory chips. It can be seen that these are all chips of SK Hynix. Solidigm, after all, is a perfectly typical offshoot of SK Hynix. The SK Hynix ACNS075, also known as Aries Aries, is the chip at the heart of the Solidigm P44 Pro. It is manufactured using TSMC's 12nm process. It is a quad-core Cortex-R5 controller that supports eight-channel flash memory, and the maximum transmission rate of each channel flash memory is 1600MT/s. The H25T2TC88C from SK Hynix is 3D TLC flash memory with 176 layers. The ONFI 4.2 protocol is used, and the maximum throughput is 1600MT/s. Two 512GB chips provide up to 1TB of storage space and two 1GB ones for the 2 TB model. DRAM is provided via an SK Hynix H54G36AYRBX257 1GB LPDDR4 module.
