Solidigm P44 Pro Spec and Price in the United States

NVME2TBM.2 22807000 MB/s read

Released October 18, 2022 · $234.99 MSRP

Solidigm built the P44 Pro around the same SK hynix Aries (ACNS075) controller and DRAM cache as the Platinum P41, and the resulting spec sheet is nearly identical: 7,000 MB/s sequential read, 1.4 million random read IOPS, 1,200TB TBW. Where it diverges is price — $234.99 at launch, well under the P41's $379.99 — positioning it as an enthusiast PCIe 4.0 option for buyers chasing flagship-tier numbers without the flagship price tag. The five-year warranty matches the rest of the high-end tier.

Tied 34th of 106 models in the SSD catalog on Sequential read — 9 models share this figure. Tied 28th of 106 models in the SSD catalog on Sequential write — 4 models share this figure.

How to choose an SSDFour questions decide almost every SSD purchase — what fits, how big, how fast, and how much it should cost.NVMe or SATAWhich interface your machine takes, how to tell without opening it, and what the speed difference actually buys you.How much SSD capacity you actually needHow to size a drive from what you already use, why leaving headroom matters, and when one bigger drive beats two small ones.M.2 sizes and SSD form factorsWhat 2280, 2242, and 2.5-inch mean, which one your machine takes, and how to check the keying before you buy.What SSD speed numbers actually tell youSequential versus random performance, why the number on the box describes the rarer case, and how to read it without being misled.PCIe generations for SSDsWhat Gen 3, Gen 4, and Gen 5 change, why a newer drive always works in an older slot, and when the extra speed is worth paying for.TLC, QLC, and DRAM-less SSDsWhat the NAND type and the controller's cache change about how a drive behaves, and when either is worth caring about.SSD endurance and warrantiesWhat TBW and DWPD actually promise, how much a normal machine writes, and when endurance is worth paying extra for.How to install an SSDFitting an M.2 or 2.5-inch drive, choosing between cloning and a clean install, and what to check on the first boot.When an SSD price is actually goodWhy price per terabyte beats any discount percentage, and why a good price on one capacity says nothing about the others.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

Class-leading all-around performance with strong sustained throughput and good power efficiency.
Good software support and a reasonable list price.
Outstanding speed, described as the fastest drive the reviewer had tested, with a large cache and excellent sustained writes.
No thermal throttling, with an onboard cache and five-year warranty.

Commonly criticised

Would benefit from a heatsink, and there is no 4TB option.
Price is slightly on the high side, and the top capacity is 2TB.
