Corsair MP700 Micro 4TB

Manufacturer: Corsair

The Corsair MP700 Micro 4TB is a high-capacity M.2 NVMe solid state drive built around the PCIe 5.0 interface, targeting users who need substantial storage alongside fast transfer rates. With 4000GB of usable internal storage, it suits workloads where both space and throughput matter. The drive uses TLC NAND and relies on a Host Memory Buffer cache scheme, keeping the design compact without an integrated heatsink.

At the core of the MP700 Micro sits the Phison PS5031-E31T controller, operating across four channels and supporting NVMe version 2. Sequential read performance reaches 9400 MB/s, while sequential writes are rated at 8100 MB/s; random I/O figures stand at 1,200,000 IOPS read and 1,400,000 IOPS write. Endurance is specified at 2400 TBW, and Corsair rates the drive at an MTBF of 1.6 million hours, backed by a five-year warranty. The unit also carries a 1500G shock resistance rating, though it ships without hardware-level AES encryption support or RGB lighting.

Pros
  • Sequential read and write speeds of 9400 MB/s and 8100 MB/s respectively indicate very fast data transfer for large files
  • Random write performance of 1,400,000 IOPS and random read of 1,200,000 IOPS support demanding workloads with many simultaneous small operations
  • A 4000GB capacity provides substantial storage space within a compact M.2 form factor
  • The 2400 TBW endurance rating is well-suited for heavy, sustained write-intensive usage over time
  • A five-year warranty offers long-term coverage assurance
  • 1500G shock resistance provides meaningful protection against physical impacts
Cons
  • No integrated heatsink, which may require users to source a separate cooling solution given the thermal demands of a PCIe 5.0 drive
  • Hardware-level AES encryption is not supported, limiting data security options for users who require it
  • Relies on Host Memory Buffer rather than dedicated DRAM cache, which ties cache performance to available system memory
  • No RGB lighting for users who prioritize visual customization within their build
Who is this for?

This drive is well-matched to users who regularly handle large file transfers or data-intensive workloads, such as video editing, 3D rendering, or working with sizable datasets, where its 9400 MB/s sequential read speed and 8100 MB/s sequential write speed translate directly into time savings. The 4000GB capacity makes it a practical choice for those who need substantial on-drive storage without adding multiple devices, while the 2400 TBW endurance rating means it can sustain prolonged heavy usage over years of operation. Users building systems on platforms that support PCIe 5.0 and NVMe 2 will be positioned to take full advantage of what this drive offers.

Who is this NOT for?

Users who require hardware-level AES encryption for data security compliance or sensitive workloads will find this drive unsuitable, as it offers no native encryption support. Since the drive depends on a Host Memory Buffer cache rather than dedicated onboard DRAM, systems with limited available RAM may not sustain peak cache performance under prolonged load, making it a poor fit for low-memory configurations. Additionally, users working in thermally constrained builds without access to aftermarket cooling solutions may face challenges, given that the drive ships without an integrated heatsink despite operating on the heat-generating PCIe 5.0 interface.

Read speed:

sequential read speed 9400 MB/s
random read speed 1200000 IOPS

The Corsair MP700 Micro 4TB delivers a sequential read speed of 9400 MB/s, making it well-suited for transferring large files at pace. On the random side, it reaches 1,200,000 IOPS, reflecting strong performance when handling numerous small, scattered read operations typical of active system workloads.

Write speed:

sequential write speed 8100 MB/s
random write speed 1400000 IOPS

The MP700 Micro 4TB is rated for a sequential write speed of 8100 MB/s, handling large sustained write operations at a strong pace. Its random write performance is specified at 1,400,000 IOPS, indicating the drive can manage a high volume of small, non-sequential write requests efficiently under demanding conditions.

The Corsair MP700 Micro 4TB is an M.2 NVMe SSD using the PCIe 5.0 interface and conforming to NVMe version 2, with 4000GB of internal storage built on TLC NAND. The drive is powered by the Phison PS5031-E31T controller operating across four channels, and uses a Host Memory Buffer cache scheme in place of dedicated DRAM. Endurance is rated at 2400 TBW alongside an MTBF of 1.6 million hours, and the drive carries a five-year warranty. It offers 1500G shock resistance but ships without an integrated heatsink, without AES hardware encryption support, and without RGB lighting.

Final Verdict

The Corsair MP700 Micro 4TB is a high-capacity PCIe 5.0 NVMe drive built for users whose workflows genuinely push storage throughput to its limits. Its combination of rapid sequential transfer rates and a 2400 TBW endurance rating signals a drive designed for sustained, demanding use rather than light everyday tasks. Prospective users should be aware of its reliance on Host Memory Buffer caching and the absence of hardware encryption and an integrated heatsink, meaning the surrounding system setup matters. For those running a compatible platform with adequate cooling and memory, the MP700 Micro 4TB represents a well-specified option within the high-capacity NVMe space.
