Goodram IRDM Pro 4TB PCIe 4.0 NVMe SSD
The Goodram IRDM Pro 4 TB is a Polish-engineered PCIe 4.0 flagship that pairs the Phison E18 controller with 3D TLC NAND, hitting 7000 MB/s sequential reads with 3000 TBW endurance backed by a 5-year warranty.
Inside the IRDM Pro 4 TB sits Phison PS5018-E18, the same eight-channel controller found in premium drives from Samsung, WD, and Corsair. Goodram pairs this controller with 3D TLC NAND Flash and a DRAM buffer up to 2 GB DDR4 for consistent performance. The drive uses the M.2 2280 form factor and ships with an integrated heatsink featuring a red-accented design distinctive to the IRDM line.
The 4 TB variant sits at the top of Goodram IRDM Pro capacity stack, above 1 TB and 2 TB models. Sequential reads top out at 7000 MB/s across all capacities, but write speeds scale with size: the 1 TB model manages 5500 MB/s writes, while 2 TB and 4 TB variants reach 6850 MB/s. Random 4K performance is rated up to 650,000 IOPS read and 700,000 IOPS write on the 4 TB model. This scaling happens because higher capacities use more NAND dies in parallel, improving write throughput and IOPS consistency.
This drive targets enthusiasts upgrading gaming PCs, content creators working with 4K video, and PS5 owners expanding storage. The included heatsink adds height, so verify clearance in thin laptops or compact ITX builds before buying. Competitors in this tier include the WD Black SN850X, Samsung 980 Pro, and Kingston KC3000, though the IRDM Pro distinguishes itself with its robust bundled cooler and competitive endurance rating. Goodram positions the IRDM Pro as a value alternative to established brands while maintaining flagship-level internals, making it particularly appealing for buyers who prioritize specs over brand cachet. The Polish manufacturer has steadily improved the IRDM series, and this generation represents their most competitive NVMe offering to date.

🚀 Performance and benchmarks
Rated at 7000 MB/s sequential reads and 6850 MB/s writes, the IRDM Pro 4 TB saturates the PCIe 4.0 x4 interface ceiling. Random 4K operations are specified at up to 650,000 IOPS read and 700,000 IOPS write, delivering snappy OS responsiveness and quick game load times. In real-world use, this translates to Windows boot times under 10 seconds and near-instant application launches compared to SATA SSDs.

- PNY XLR8 CS3140 1 TB: 7,500 MB/s read, 5,650 MB/s write
- PNY XLR8 CS3140 2 TB: 7,500 MB/s read, 6,850 MB/s write
- Asgard AN4 512 GB: 7,500 MB/s read, 5,500 MB/s write
- Asgard AN4 1 TB: 7,500 MB/s read, 5,500 MB/s write
- Goodram IRDM Pro 4 TB (this drive): 7,000 MB/s read, 6,850 MB/s write
The Phison E18 controller employs SLC caching to accelerate burst writes. Independent reviews show the IRDM Pro sustaining high write speeds for several dozen gigabytes before dropping to steady-state TLC write speeds—more than sufficient for typical gaming and productivity workloads. For large file transfers like 4K video exports or game installs, you will see the drive hit its advertised speeds consistently.
Compared to PCIe 3.0 drives like the Samsung 970 EVO Plus, the IRDM Pro 4 TB offers up to twice the sequential throughput. Gaming load times improve by 10–20% over SATA, though the real-world gains depend on whether the title is optimized for DirectStorage. For PS5 use, the drive meets Sony 5,500 MB/s+ read recommendation and fits within the console 110 × 25 × 11.25 mm heatsink envelope.
🖥️ Endurance and warranty
Goodram backs the IRDM Pro 4 TB with a 5-year warranty limited by the 3000 TBW endurance rating. TBW measures the total terabytes you can write before the warranty expires—at 3000 TBW, this drive handles over 8 TB of writes daily for five years. For typical users writing 50 GB per day, that translates to roughly 164 years of use, far exceeding the warranty period.
Endurance scales with capacity: the 1 TB model is rated 700 TBW, while 2 TB offers 1400 TBW. If you exceed the TBW threshold within five years, Goodram reserves the right to deny warranty claims. The drive lacks an official MTBF rating in public specifications, but the Phison E18 controller and 3D TLC NAND combination has proven reliability across multiple product lines. Warranty claims go through Goodram Polish support, so keep your proof of purchase if buying internationally.

Conclusion
Buy the Goodram IRDM Pro 4 TB if you want flagship PCIe 4.0 performance with a premium heatsink included and do not want to pay Samsung or WD tax. The 3000 TBW endurance and Phison E18 internals make it a solid choice for PS5 expansion, game libraries, and creative workloads that require sustained write performance. Skip it if you need DRAM-less value or your laptop cannot fit the thick heatsink—consider the WD Black SN770 or Kingston NV2 instead. The IRDM Pro 4 TB earns its place as a capable alternative to established brands, especially for buyers who value bundled cooling and do not mind trading some brand recognition for savings. At its current positioning, the drive offers competitive specifications that match or exceed many tier-one flagships.
