PNY CS2150 4TB PCIe 5.0 x4 NVMe M.2 2280

The PNY CS2150 hits 10,200 MB/s sequential reads, which is top of the charts. But it's DRAM-less, so random performance is just average at the 59th percentile. At $520 for 4TB, it's a niche pick for sequential speed junkies, not an all-rounder.

10,200 MB/s read and 8,300 MB/s write are the headline numbers, and they're legit. That read speed is best-in-class, putting this drive at the top of the charts for sequential throughput. The PCIe 5.0 x4 interface is doing real work here. But here's the thing: this is a DRAM-less design. Most drives pushing these speeds lean on a DRAM cache to keep things snappy, and PNY skipped it. The random performance ranking of 59th percentile tells the story. Sequential transfers are blazing, but when you're loading a game with thousands of tiny files, it's just average.

The 4TB capacity is a standout at 93rd percentile, so you've got room for a massive game library or a serious video editing workflow. Endurance at 62nd percentile is solid but not remarkable. The feature set ranks at 85th percentile, which is strong, and hardware encryption is included. For a drive this fast, the lack of DRAM is the one spec that keeps nagging at us.

Against the Samsung 990 Pro and WD Black SN850X, the PNY CS2150 wins on raw sequential speed. 10,200 MB/s read crushes what those PCIe 4.0 drives can do. But both the 990 Pro and SN850X have DRAM caches, which means their random performance and sustained writes hold up better under mixed workloads. The Micron T710 is another PCIe 5.0 competitor, and it brings DRAM to the table, which likely explains why the PNY's random performance is only average. The Samsung 9100 PRO and Crucial T500 have also moved into our top 5, and both are strong all-rounders that make the PNY's DRAM-less tradeoff harder to swallow. The Kingston Fury Renegade 4TB and Seagate FireCuda 530R are PCIe 4.0 drives that trade blows on endurance and random performance while costing less. If you're building a gaming rig and want the fastest sequential loads, the PNY makes a case. If you're doing anything that touches lots of small files, the competition looks better.

The single US listing shows $520, which is a lot of money for a 4TB drive. But you're paying for PCIe 5.0 speed, and at 10,200 MB/s read, this is one of the fastest consumer drives on the market. The problem is the DRAM-less design. At this price point, you'd expect a drive that excels across the board, not just in sequential transfers. The endurance and random performance rankings don't justify a premium over something like the Samsung 990 Pro or WD Black SN850X, which are PCIe 4.0 but often cheaper and more balanced. If you need raw sequential speed and 4TB of space, the price might work. If you want all-around performance, you're paying a lot for one trick.

The PNY CS2150 hits 10,200 MB/s sequential reads and 8,300 MB/s writes. That puts it in the 95th percentile for speed in our database, which is the absolute best right now for consumer drives. You're getting 4TB of TLC NAND on a PCIe 5.0 x4 interface, and it's DRAM-less, which is a bit of a head-scratcher for a drive this fast. The 5-year warranty and 1.5 million hour MTBF are solid, but there's no price listed from our single US listing at $520, so we can't fully judge the value yet.

For console use it scores 71.2 out of 100, and gaming lands at 69.5. The total score of 68 is dragged down hard by the portable category at 18.8, which makes sense since this is a desktop-focused M.2 2280 drive. The endurance ranking sits at 62nd percentile, which is middle of the pack, and random performance at 59th percentile is about average. So you've got a drive that screams in sequential workloads but doesn't stand out when things get scattered.

If you're building a portable rig or need a drive for a laptop, skip this. The portable score of 18.8 out of 100 is one of the worst we've seen in that category. The DRAM-less design also means anyone doing heavy mixed workloads, like video editing with lots of small file reads and writes, won't get the most out of this drive. Random performance at 59th percentile is just average, and endurance at 62nd percentile won't impress anyone who writes terabytes of data daily. If you want balanced performance, look at the Samsung 990 Pro or WD Black SN850X instead.

The PNY CS2150 is a speed demon in one specific lane. 10,200 MB/s sequential reads are genuinely impressive, and 4TB of capacity is a lot of room. But the DRAM-less design holds it back where it matters for real-world use. Random performance is average, endurance is unremarkable, and the portable score is a disaster. At $520, you're paying a premium for sequential speed while sacrificing balance. If you're moving massive files around all day, this drive will fly. For everyone else, a DRAM-equipped PCIe 4.0 drive will feel just as fast in daily use and cost less.
