Crucial 1TB SSD PCIe 4.0 NVMe M.2

6600 MB/s reads and 700K random write IOPS make the P5 Plus a genuine Gen4 performer, landing in the top 21% for speed and top 11% for random operations. The 4.8/5 rating from 122 reviews backs up the performance story. Just watch the price, EUR 122 to EUR 362 is a wild spread, and the DRAM-less design means sustained writes aren't its strong suit.

6600 MB/s read and 5000 MB/s write. Those are the headline numbers, and they're legit. In our database, this drive lands in the 79th percentile for speed, which translates to well above average but not quite top of the charts. The random performance is where it actually shines brighter, 630K read IOPS and 700K write IOPS put it in the 89th percentile for random operations. That's a standout result, and it's why this drive feels snappy in everyday use, not just when you're moving giant files around.

The catch is that this is a DRAM-less design. Normally that's a red flag for sustained performance, but Micron's controller does a solid job compensating with HMB (host memory buffer) support. The 2,000,000 hour MTBF and 5-year warranty back up the reliability story. Just keep in mind that full speed requires a PCIe 4.0 slot. Drop it in a Gen3 board and you'll leave a chunk of that 6600 MB/s on the table, though it'll still work fine.

Against the Samsung 990 EVO, the P5 Plus actually holds its own on sequential reads at 6600 MB/s, though Samsung's newer drive has better sustained write performance thanks to its DRAM cache. The Kingston KC3000 is the more direct competitor here, with similar Gen4 speeds but higher endurance ratings, typically 800 TBW or more for the 1TB model. The MSI SPATIUM M480 PRO and Corsair MP700 Elite both push closer to 7000 MB/s reads, but you'll pay a premium for that extra few hundred MB/s that most people will never notice outside of benchmarks. The Western Digital WD Blue SN5100 is the budget alternative, slower on paper but often cheaper. If raw sequential speed is your priority and you find the P5 Plus at a good price, it's a smart pick. If endurance matters more, the KC3000 is worth the extra cash.

Pricing is all over the place depending on where you shop. In EUR, you're looking at a spread from EUR 122 to EUR 362 across three listings in Spain, France, and Italy. That's a EUR 240 gap for the exact same drive, which is frankly ridiculous. If you can find it near the EUR 122 mark, this is an absolute steal for Gen4 performance. At EUR 362, you're paying Samsung 990 Pro money for a drive that doesn't quite hit that tier. The GBP 85 listing in the UK also looks very competitive. Our affordability score lands at the 51st percentile, dead average, but that's dragged up by the expensive listings. Shop around and this becomes a budget-friendly pick.

The Crucial P5 Plus hits 6600 MB/s sequential reads and 5000 MB/s writes, which puts it in the top 21% of drives in our database for raw speed. That's a serious number for a 1TB Gen4 drive, and it lands at 82.5/100 overall in our scoring. The social proof is even stronger, sitting in the 95th percentile with a 4.8/5 rating across 122 reviews, so buyers clearly aren't regretting this one.

But the story gets more interesting when you dig into the details. This is a DRAM-less drive using Micron's own DMO1B2 controller and TLC NAND, which is a bit unusual for a drive pushing these speeds. The endurance rating of 600 TBW is decent but not class-leading, and several owners mention it runs warm under sustained load. Still, for the money, especially at the lower end of that EUR 122 to EUR 362 spread, it's hard to argue with the performance you're getting.

If you're doing heavy sustained writes, like constant 4K video editing or running a database server, the 600 TBW endurance and DRAM-less design will hold you back. The portable use case score of 19.9/100 is one of the worst we've seen, so don't buy this for an external enclosure that'll get moved around a lot. And if you're still on a PCIe 3.0 board with no plans to upgrade, you're paying for Gen4 speeds you'll never see. In that case, a cheaper Gen3 drive or a budget Gen4 option like the WD Blue SN5100 makes more sense.

The Crucial P5 Plus is a fast, reliable Gen4 drive that punches above its price point when you shop smart. The 6600 MB/s reads and 700K random write IOPS are genuinely impressive, and the 95th percentile social proof tells you real owners are happy with it. The DRAM-less design and 600 TBW endurance are the trade-offs, and they're real ones if you're hammering the drive with heavy sustained writes. But for gaming, everyday use, and even most creative workloads, this drive delivers. Find it near the low end of that EUR 122 to EUR 362 range and it's an easy recommendation.
