New Corsair MP700 PCIe 5 SSD launches with lightning-quick speeds

Corsair takes on Crucial with SSD that's 40 percent quicker than PCIe 4 drives, but requires serious cooling, with Corsair recommending a waterblock.

Corsair MP700 SSD

The first Corsair PCIe 5 SSD has finally launched, with the company claiming that the M.2 Corsair MP700 is up to 40 percent quicker than the very fastest PCIe 4 SSDs from the last generation, such as the Samsung 990 Pro.

PCIe 4 SSD speeds generally top out at just over 7,000MB/s, with the theoretical limit of the 4x PCIe 4 interface maxing out at 8,000MB/s. However, Corsair claims that the MP700 sequential read speed is 10GB/s, and quotes the same speed for sequential writes as well.

These speeds are a fair bit behind the 12.4GB/s Crucial claims for the Crucial T700 PCIe 5 SSD, but they’re still a long way in front of the performance of current PCIe 4 drives. It’s also worth bearing in mind that these speeds will only be seen in very specific scenarios where you’re transferring large amounts of data in one go – in most real-world use scenarios you’re unlikely to notice the difference.

Corsair also quotes random read performance of 1.5 million IOPS and random write performance of 1.7 million IOPS. As a point of comparison, the WD Black SN850X has maximum random read and write figures of 1.2 million and 1.1 million respectively, so the Corsair MP700 is definitely quicker, even if it isn’t twice as fast.

These blistering data transfer speeds come at a cost in terms of cooling, though, as the Corsair MP700 will throttle its speed if it’s left to its own devices. Corsair says you can either fit a heatsink that comes with your motherboard, but it also recommends using its own Corsair Hydro X XM2 waterblock, which it says will deliver “top-of-the-line cooling and performance while virtually eliminating throughput throttling.”

The company has also provided a Corsair MP700 installation guide, which you can see in the video below.
