Our Verdict
The Corsair MP700 Professional completed in a digital tie with the Adata Legend 970 for best-in-class PCIe 5.0 efficiency. In case you have the mandatory M.2 slot and need most pace, it’s a short-lister.

Although PCIe 5.0 M.2 slots are nonetheless comparatively uncommon, when you have one, a premium SSD such because the Corsair MP700 Professional will present a pleasant bump in total efficiency.
After I say premium, I’m speaking about efficiency that’s proper there with the very best NVMe SSDs we’ve examined. And sure, I additionally imply it’s priced like a top-tier performer.
Additional studying: See our roundup of the very best PCI3 4.0 SSDs to find out about competing merchandise.
What are the Corsair MP700 Professional’s options?
As intimated, the MP700 Professional is a PCIe 5.0 x4, NVMe SSD within the 2280 (22mm extensive, 80mm lengthy) kind issue. The controller is a Phison PS5026-E26 and the NAND is 232-layer TLC (Triple-Degree Cell/3-bit). There’s a whopping 2GB of DRAM major cache for each 1TB of capability–double the norm. Good.
The 2280 MP700 Professional is obtainable with or with no moderately hefty and tall, fan-cooled heatsink (proven under with the ability cable for the fan). Both manner the drive is warrantied for 5 years or 700TBW (terabytes which may be written) per 1TB of capability.

In case you weren’t conscious, TBW mitigates the guarantee time period as miles do in an car guarantee. Corsair’s 700TBW is 100TBW above common, however nowhere close to the Seagate FireCuda 540 or Seagate Recreation Drive PS5‘s stage, which is nearly double that also.
How a lot does the Corsair MP700 Professional value?
The Corsair MP700 Professional with heatsink is at present accessible in 1TB and 2TB (examined) variations, for $190 and $325, respectively. Sans heatsink, it’s $180 and $315.
Corsair didn’t ship us the 1TB model, therefore we’re undecided if it sports activities a smaller heatsink/cooler that’s price solely half the premium. No pricing was introduced for an upcoming 4TB capability.
How briskly is the Corsair MP700 Professional?
Corsair’s MP700 Professional traded blows with the fast-in-the-real-world Adata Legend 970 to an total statistical draw.
If we ranked solely on CrystalDiskMark 8 sequential take a look at the MP700 would’ve dominated the Adata, although it misplaced by a small margin to the also-formidable Essential T700.
CrystalDiskMark 8 4K file efficiency was a barely completely different story with the Adata besting the the MP700 Professional by greater than a little bit, largely due to the latter’s drop-off within the 32-queue write.
Not one of the different drives may match the Seagate FireCuda 540 within the 48GB transfers. It wasn’t even notably shut, although the MP700 Professional continues to be among the many quickest. For some purpose, late-model host reminiscence buffer (HMB) designs (none proven) do very nicely on this and the 450GB write exams.
As you’ll be able to see under, there’s little distinction between the primary three late mannequin PCIe 5.0 NVMe SSDs within the 450GB write take a look at–nicely throughout the regular statistical variance. Having referred to as out the Seagate FireCuda 540 for its superior 48GB transfers, I need to additionally word that it was moderately slothful for a PCIe 4.0/5.0 SSD on this take a look at.
Be aware that most of the quickest drives within the 450GB write take a look at are PCIe 4.0 with, once more, some being host reminiscence buffer (HMB) designs.
We did discover some oddities: It took the MP700 Professional almost 30 seconds to format moderately than the conventional 5 to 10 seconds. There was additionally a momentary steep dip at finish of the 450GB write to round 950MBps. That’s hardly tragic, but it surely was noticeable.
Additionally, once we wrote an extra 1.35TB in two giant information to fill the 2TB MP700 Professional to close capability, writes vacillated between 120MBps and three.2GBps although largely in the direction of the latter. Little question the dip and vacillations had been the good caching allotting extra secondary cache on the fly (NAND written as SLC as a substitute of TLC).
The MP700 Professional lastly leveled off at about 950MBps across the 1200GB mark of the second write. Be aware that writing 1.35TB in two giant information is a state of affairs few will ever topic the MP700 to, and almost 1GBps continues to be fairly quick within the grand scheme, so most customers can ignore that habits.
Must you purchase the Corsair MP700 Professional?
The Corsair MP700 is a wonderful NVMe SSD that may present top-flight efficiency in any system sporting a PCIe 5.0 M.2 slot. Nonetheless, the Adata Legend 970 and Essential T700 are proper there with it performance-wise, so I’m calling the shopping for resolution a choose’em primarily based on present pricing and model desire.
How we take a look at
Drive exams at present make the most of Home windows 11, 64-bit operating on an X790 (PCIe 4.0/5.0) motherboard/i5-12400 CPU combo with two Kingston Fury 32GB DDR5 4800MHz modules (64GB of reminiscence complete). Each 20Gbps USB and Thunderbolt 4 are built-in to the again panel and Intel CPU/GPU graphics are used. The 48GB switch exams make the most of an ImDisk RAM disk taking on 58GB of the 64GB of complete reminiscence. The 450GB file is transferred from a 2TB Samsung 990 Professional which additionally runs the OS.
Every take a look at is carried out on a newly formatted and TRIM’d drive so the outcomes are optimum. Be aware that in regular use, as a drive fills up, efficiency might lower as a result of much less NAND for secondary caching, in addition to different elements. This may be much less of an element with the present crop of SSDs with far sooner late-generation NAND.
Caveat: The efficiency numbers proven apply solely to the drive we had been shipped and to the capability examined. SSD efficiency can and can differ by capability as a result of extra or fewer chips to shotgun reads/writes throughout and the quantity of NAND accessible for secondary caching. Distributors additionally sometimes swap elements. In case you ever discover a big discrepancy between the efficiency you expertise and that which we report, by all means, tell us.
