SABRENT Rocket 4 Plus

The Sabrent Rocket 4 Plus 4TB is a fast, high-capacity PCIe 4.0 drive with excellent random performance and strong endurance. At $880, it's pricey but competitive with the Samsung 990 PRO and WD Black SN850X. The main concerns are heat output and a frustrating RMA process reported by some users. If you need 4TB of fast storage and have a decent heatsink, this is a solid buy.

The headline numbers are impressive. 7100 MB/s sequential read and 6600 MB/s write put this drive in the 83rd percentile for speed in our database. That's not the absolute fastest PCIe 4.0 drive anymore, but it's close enough that you'd need a stopwatch to tell the difference in real-world use. The random performance is where this drive really shines. 650K random read IOPS and 700K random write IOPS land it in the 87th percentile. That means snappy application launches, fast file searches, and smooth multitasking when you've got a dozen things open.

Real-world implications? Loading games from this drive feels instant. Scrubbing through 4K video timelines is smooth. And if you're running a database or VMs, the random IOPS matter more than sequential speeds. The drive supports APST, ASPM, and L1.2 power management, so it won't torch your laptop battery when idle. But here's the trade-off: this drive runs hot under sustained load. Multiple reviewers mention needing a decent heatsink to prevent throttling. If your motherboard has a built-in M.2 shield, you're probably fine. If not, budget for an aftermarket cooler.

The Samsung 990 PRO is the elephant in the room. It's faster in sequential reads, has better brand recognition, and Samsung's Magician software is genuinely useful. But the 990 PRO 4TB is usually more expensive, and Samsung had that whole firmware fiasco with the 980 PRO that left a bad taste. The WD Black SN850X is the value play. It's often cheaper than both, with performance that's close enough that most people won't notice the difference. The trade-off is slightly lower endurance and a less polished software suite.

The Micron T710 and Seagate FireCuda 530R are also worth mentioning. The FireCuda 530R is built like a tank with a great endurance rating, but it's usually pricier. The Micron T710 is a solid performer but harder to find at retail. The Kingston Fury Renegade 4TB is probably the closest direct competitor to the Sabrent. Similar specs, similar price, similar performance. The Sabrent's advantage is the included cloning software and the sector size utility, which is genuinely useful if you're migrating from an older system. The Kingston's advantage is better availability and sometimes lower street pricing.

At $880 for 4TB, you're paying about $220 per terabyte. That's not a bargain, but it's also not outrageous for a drive with this level of performance and endurance. The Samsung 990 PRO 4TB typically runs around the same price or slightly higher, and the WD Black SN850X 4TB is usually a bit cheaper. What you're getting with the Sabrent is a proven controller, strong random performance, and that 3000 TBW endurance rating. For a workstation drive that's going to see heavy writes, that endurance matters.

The value equation shifts depending on your use case. If you're a gamer who just wants fast load times, you could save money with a 2TB drive or a slightly slower 4TB option. But if you need 4TB of fast storage in a single slot, your options are limited. The Rocket 4 Plus sits in a sweet spot where you're not paying the absolute premium for the top-tier Samsung, but you're still getting near-top-tier performance. The included cloning software adds a bit of value too, especially if you're migrating from an older drive.

The Sabrent Rocket 4 Plus is one of those drives that makes you remember why you got into PC building in the first place. It's a 4TB M.2 stick that pushes 7100 MB/s reads and 6600 MB/s writes, which puts it near the top of the PCIe 4.0 food chain. We're talking about a drive that can move a 100GB game folder in the time it takes to grab a coffee. And with 4TB of space, you're not going to be playing the uninstall shuffle anytime soon.

This drive is aimed squarely at people who need serious throughput without jumping to PCIe 5.0. Workstation users, content creators, and gamers with large libraries are the sweet spot. The Phison PS5018-E18 controller paired with TLC NAND and a DRAM cache is a proven combo. It's not the newest kid on the block, but it's a known quantity that delivers consistent performance. The 3000 TBW endurance rating means you can write about 1.6TB per day for five years before hitting the warranty limit. That's a lot of video renders.

What makes this interesting is the price. At $880 for 4TB, it's not cheap, but it's also not the most expensive option in this tier. You're paying for capacity and speed in one package. The included Acronis True Image software for cloning is a nice touch, and the sector size utility is genuinely useful if you're migrating from an older drive. Sabrent has been around long enough to know what enthusiasts want, and this drive mostly delivers.

If you're building a budget gaming PC or just need extra storage for your Steam library, this drive is overkill. A cheaper PCIe 4.0 drive or even a good SATA SSD will load games nearly as fast in real-world use. You're paying a premium for random performance and endurance that you won't fully utilize. Look at something like the WD Black SN770 or a Crucial P3 Plus instead.

Also skip this if you're the type who wants hassle-free warranty support. The RMA complaints are concerning, with one user reporting their drive sat at a residential address for weeks. Samsung's support track record is generally better, and the 990 PRO is a safer bet if peace of mind matters more than saving a few bucks. And if you're using a laptop without a heatsink, the thermal throttling will eat into the performance you paid for.

For workstation users and content creators who need 4TB of fast storage in a single slot, the Sabrent Rocket 4 Plus is a strong pick. The random performance is excellent, the endurance rating is solid, and the included software makes migration painless. Just make sure you have a heatsink, because this drive will throttle under sustained load without one. The 3000 TBW rating means you can hammer this drive with writes for years without worrying about wearing it out.

For gamers, the calculus is a bit different. You don't need 650K random IOPS to load games. A cheaper 4TB drive or even a 2TB drive would serve you just as well. But if you're the type who wants a single drive for everything, games, OS, work files, and you don't want to think about storage management, this is a great all-rounder. The customer support complaints are concerning though. If you're the type who values peace of mind, the Samsung 990 PRO's better support track record might be worth the premium.
