Corsair MP600 Pro XT Review


One look at the Corsair MP600 Pro XT (starting at $149.99 for the 1TB model tested) with its massive finned matte black heatsink should be enough to convince anyone that this internal SSD is a beast built for gaming at home. high impact in a spacious desktop platform. This impression is confirmed by the MP600 Pro XT’s sizzling sequential read and write speeds, which exceeded its ratings in our tests, and its 4K write speed, the fastest we’ve ever recorded. If you don’t need such a heavy heatsink, however, plenty of gaming-centric speedsters, starting with the Editor’s Choice award-winning Acer Predator GM7000, await you in the wings.

Two cool choices

The Corsair MP600 Pro XT is a four-lane PCIe 4.0 drive built on a “gumstick” M.2 Type-2280 circuit board (80mm long). It uses the NVMe 1.4 protocol on the PCIe 4.0 bus and includes Phison’s E18 controller, which we’ve seen in other speedsters such as the Kingston KC3000 and the special T-Force Cardea A440 Pro series. The drive is based on Micron’s 176-layer 3D NAND TLC flash memory. (Curious about some of that terminology? Check out our glossary of SSD jargon.)

Since 1982, PCMag has tested and reviewed thousands of products to help you make better buying decisions. (See how we test.)

With its heatsink, the MP600 Pro XT is just 20mm tall, far too big to fit in a PlayStation 5 or most laptops. If you really wanted to use this drive with a PS5, you can remove the heatsink by pulling the finned part away from the frame and then lifting the M.2 stick. (Corsair recommends(Opens in a new window) use a plastic prying tool for this; if you don’t have one on hand – and who has one? – a small flathead screwdriver will also work.) Removing the heatsink requires some delicacy. It also defeats the purpose of buying this drive, as we’ve found plenty of SSDs that work well with the PS5 right out of the box.

Corsair offers another version of this SSD, the Corsair MP600 Pro XT Hydro X, which swaps the aluminum heat sink for a water block and can be integrated into the cooling loop of a water-cooled rig. The Hydro X version is only available in 2TB and 4TB capacities, priced at $30 and $15 respectively compared to the air-cooled versions when you buy direct from Corsair. The retail price of the Hydro X, particularly the 2TB model, varies wildly, so you may need to shop around for the best deal. Corsair and its partners also sell the block separately, for use with any M.2 drive, like the Hydro X Series XM2 SSD Water Block ($39.99).

Retailing for around $150, the MP600 Pro XT sits in the middle of the pack, price-wise, for elite PCI Express 4.0 drives. You pay a bit more for the Corsair’s heatsink, but if you have a desktop rig that will fit it, it might be worth it.

The MP600 Pro XT’s durability ratings are 700 TBW for 1TB, 1,400 TBW for 2TB, and 3,000 TBW for 4TB. These numbers match the Silicon Power XS70 for all three capacities and the MSI Spatium M480 HS for both lower sizes (the MSI doesn’t have a 4TB model). They’re also similar to other TLC-based speedsters like the Samsung SSD 980 Pro, whose 1TB and 2TB models are rated at 600 TBW and 1,200 TBW respectively. That said, a few PCIe 4.0 drives offer higher durability ratings, such as the MSI Spatium M470’s 1,600 TB for 1 TB and 3,300 TB for 2 TB. At the other extreme, the Mushkin Delta, which uses QLC memory less durable, is rated at only 200 ToW for 1 TB, 400 ToW for 2 TB, and 800 ToW for 4 TB.

The “terabytes written” specification is a manufacturer’s estimate of how much data can be written to a drive before some cells begin to fail and are taken out of service. TBW typically scales 1:1 with capacity, although the 4TB MP600 Pro XT is rated at just over double the TBW of the 2TB stick, as with the 4TB versions of the Silicon Power XS70 and Acer Predator GM7000.

Corsair warrants the MP600 Pro XT for five years (or until you reach the rated TBW figure in data writes, whichever comes first). The drive supports AES 256-bit hardware encryption, the industry standard for consumer-level data protection.

MP600 Pro XT review: A new brand of 4K writing

We test PCI Express 4.0 internal SSDs using a desktop test bench with an MSI X570 motherboard and AMD Ryzen processor, 16GB of Corsair Dominator DDR4 3600MHz memory, and a discrete graphics card .

We ran the Corsair MP600 Pro XT through our usual internal SSD benchmarks, including Crystal DiskMark 6.0 and PCMark 10 Storage. We’re also including results from a relatively new test, UL’s 3DMark Storage Benchmark, which measures a drive’s performance in a number of gaming-related tasks.

Crystal DiskMark’s sequential speed tests provide a traditional measure of drive throughput, simulating straight-line transfers of large files at best.

In the Crystal DiskMark tests, the MP600 Pro XT exceeded both its sequential read and sequential write speed ratings, reading speed by over 300MB/s, putting it near the top of our database test as one of four discs to join “the 7,400 club”. While its 4K read speed was only average for a high-end SSD, the Corsair blew away the competition by setting a new 4K write score record for PC Labs.

The PCMark 10 overall storage test score of the MP600 Pro XT puts it in a tight bunch ahead of the pack. This test measures the speed of a drive in performing various routine tasks such as loading games and launching programs including the Windows operating system. Game launch speeds for Battlefield 5, Overwatch, and Call of Duty: Black Ops 4 fell in the middle of our test group. The drive ISO copy score was near the top, while the other PCMark 10 trace scores were mediocre.

We built our 3DMark test results, but for the most part we only compared the most recent of our comparison drives. The MP600 Pro XT’s score was typical of these elite speedsters, falling within 100 points of all but two drives. Only the WD Black SN850 broke away from the pack with a higher score, and even that wasn’t drastically different.

An SSD with speed and pizzazz

The Corsair MP600 Pro XT cuts a formidable figure with its brushed, matte black fins, and it delivered blazing speeds in our Crystal DiskMark tests. If it doesn’t fit (literally or figuratively) your setup, you can choose from other high-end PCI Express 4.0 M.2 drives, such as the Acer GM7000 and the ADATA XPG Gammix S70 Blade , both PCMag Editors’ Choice. products. That said, upgrading to this SSD is a way to add style, substance, and speed to your rig.

The essential

The Corsair MP600 Pro XT internal SSD has the raw speed for high-impact gaming and the cooling to stay in top form under pressure, but you’ll want to look elsewhere if you need a drive for a laptop or PS5.
