The Corsair MP400 SSD Review

The Corsair MP400 SSD is a full-fat PCIe 2.0 x4 drive with a whopping 32GB of NAND flash memory. The drive features Corsair’s new LSI 9260 controller, which the company claims is capable of supporting up to 550 MB/s reads and up to 490 MB/s writes.

The MP400 is Corsair’s first SSD that features the LSI 9260 controller, and the company says the controller offers a host of improvements over the previous LSI 9200 controller used in the previous Corsair SSDs.

The MP400 SSD comes in a single-sided, dual-bay design with a pair of mounting rails for easy installation. The drive is designed to be compatible with the Corsair Link software and features Corsair’s own TriXX cache to increase performance.

Corsair has also included a limited lifetime warranty with the MP400 SSD.


This is the system we used to test the Corsair MP400

  • CPU: AMD Ryzen 5 3600X
  • CPU Cooler: AMD Wraith Spire
  • RAM: 32GB T-Force Vulcan Z CL18 @3,600MHz
  • Motherboard: MSI B550 Pro VDH Wi-Fi
  • Graphics card: EVGA GeForce RTX 2070 XC Gaming
  • OS SSD: Samsung 980 Pro @ 500GB
  • Power Supply: Thermaltake Toughpower GF1 750W
  • Case: ThermalTake Core V21


Here’s how the Corsair MP400 performed in our suite of benchmark tests:

  • CrystalDiskMark Sequential: 3,460.62MB/s (read); 3,063.75MB/s (write)
  • CrystalDiskMark Random Q32: 1,541.91 MB/s (read); 2,487.69MB/s (write)
  • 10GB file transfer: 5.51 seconds
  • 10GB folder transfer: 6.33 seconds
  • PCMark10 SSD: 1,303 points

Corsair MP400: Performance

Corsair MP400 ssd Review

As a general-purpose disk, 400 TBW isn’t much of a shortcoming, although you might not want to use it for 8K video workflows and similar things. One thing this drive has going for it is speed. 

However, this would make an ideal drive for a gaming rig to store a game library because playing a game requires reading from the drive far more than writing to it.

Despite being an affordable PCIe drive, this drive competes with some of the best in the industry. According to our testing, the Corsair MP400 delivers sequential read and write speeds as fast or faster than any of the PCIe 3.0 SSDs we’ve tested so far, including the WD Black SN750 and Samsung 970 Pro. Its random read and write speeds are also astonishing, hitting 1,541MB/s in random reads and 2,487MB/s in random writes – close to what we’ve seen on PCIe 4.0 SSDs.

When it comes to storage and value, you can’t do better than this drive. This drive is more than justified by the huge speed difference over a SATA drive as long as you have a PCIe slot for it.

In terms of speed and price, SK Hynix’s Gold P31 drive offers some competition (at least on sale), as it offers more speed and less price per gigabyte than similar drives. However, it is only available in 500GB and 1TB capacities. In light of the recent price of $134 (about £100, AU$175), the 1TB drive is a better value, but not if its original price of $224 (about £165, AU$295) is reinstated.

Corsair MP400: Pros and Cons

Pros Cons
Large capacity Lower endurance
Exceptional speed Value dropoff at a higher capacity

It’s worth buying if…

Fast game libraries are what you need

Thanks to its speed and space, the Corsair MP400 is a great drive to go for if you want your PC games to load quickly. It doesn’t offer the same speeds as PCIe 4.0 drives, but it is much faster than PCIe 3.0 SSDs, and it has a great price for the amount of storage it offers.

There is no PCIe 4.0 slot in your computer

If you have the right motherboard and processor, you can get faster drives. On the other hand, if you don’t, then the Corsair MP400 should suffice. This is a great value in comparison to buying a PCIe 4.0 drive that will bottleneck in a PCIe 3.0 slot.

You’re a value-oriented builder

Corsair’s MP400 is a serious value. Particularly impressive is the 2TB model, which offers a lot of storage at prices that are typical of SATA SSDs, but it’s actually a PCIe SSD, and it’s pretty fast. Furthermore, it’s even faster than most PCIe SSDs.

Do not purchase if…

A lot of data needs to be written regularly

Due to its use of QLC NAND, the Corsair MP400 is not very durable. The drive has a write speed of 400 TBW or 200 drive-writes. You might run out of space on your drive if you’re constantly dumping massive files onto it. At 400 TBW it might not fail, but do you want to take that chance with 2TB of data?

A fast drive is important to you

There’s no PCIe 4.0 SSD here, but it’s a fast drive. When slotted into a PCIe 4.0 x4 slot, its speeds pale in comparison with those of the latest generation of SSDs. You should consider the Samsung 980 Pro if you need the most speed.

You’re looking for something flashy

Corsair’s gear usually has a lot of flairs. RAM modules from Corsair are razzle-dazzle, and the company’s cases and gaming peripherals are rarely without RGB. However, Corsair probably knew this SSD would sit halfway beneath the graphics card, so it’s a pretty plain, all-black design.


The Corsair MP400 isn’t your typical PCIe SSD. It’s fast for an SSD on PCIe 3.0 but priced more like an affordable SATA drive. As far as we can tell, the only trade-off is the QLC NAND, which limits its endurance slightly.
