Corsair’s thick new SSD smokes all first-gen PCIe 4.0 drives

The quickest SSDs all leverage the PCIe 4.0 bus, however not all are created equal—when it comes to rated specs, it largely boils all the way down to once they have been launched. Timing issues, as a result of the primary crop of PCIe 4.0 SSDs topped out at round 5,000MB/s. Then got here a brand new spherical of reminiscence controller {hardware}, which pushes speeds north of seven,000MB/s. Corsair’s new MP600 Professional XT falls into the latter class, whereas additionally boasting extremely excessive IOPS.

That is Corsair’s quickest SSD to this point. It is out there in 4TB, 2TB, and 1TB capacities, and whereas specs differ between the smallest and two largest drives, all three are rated to ship as much as 7,100MB/s of sequential learn efficiency. This is a snapshot of the related velocity metrics:

  • 4TB—7,100MB/s seq. reads; 5,800MB/s seq. writes; 1.2 million random learn IOPs; 900K random write IOPS
  • 2TB—7,100MB/s seq. reads; 6,800MB/s seq. writes; 1.2 million random learn IOPs; 1 million random write IOPS
  • 1TB—7,100MB/s seq. reads; 5,800MB/s seq. writes; 1.2 million random learn IOPs; 900K random write IOPS

The rated IOPS is the place the MP600 Professional XT separates itself from the competitors. Take for instance Sabrent’s Rocket 4 Plus, one of many finest SSDs for gaming. It provides up comparable sequential learn (7,100MB/s) and write (6,600MB/s) specs, however the random learn and write IOPS verify in at 650,000 and 700,000, respectively. WD’s SN850, one other speedy SSD, hits 1 million IOPs for reads, however ranges between 680,000 and 720,000 IOPS (relying on capability) for writes.

This would possibly not all the time come into play—IOPS can have an effect on efficiency when accessing a bunch of information which might be scattered throughout the NAND flash reminiscence chips. When it comes to real-world utilization, most customers will not really discover a lot of a distinction, although it nonetheless speaks to the standard and capabilities of the NAND, controller, and firmware.

On this case, Corsair pairs Micron’s 176-layer 3D triple-level cell (TLC) NAND reminiscence chips with the Phison’s PS5018-E18 controller. It is the identical controller as discovered on Corsair’s MP600 Professional (non-XT) launched earlier this yr (and many of the quickest SSDs in the marketplace), however the NAND is an improve over the 96-layer chips the non-XT fashions use.

In these phrases it is really an identical to the Seagate FireCuda 530 we just lately reviewed, which makes use of the identical NAND and controller, although is tweaked to ship ever-so-slightly larger sequential efficiency in 2TB trim. The distinction there’s more likely to come all the way down to firmware.

We’re placing the Corsair MP600 Professional XT by it is paces proper now, simply to see the way it compares with Seagate’s best.

Corsair additionally outfits its MP600 Professional XT with a “uniquely styled aluminum heatspreader” to maintain toasty temps at bay. It is chonky for certain, although is definitely reasonably cute within the flesh. Moreover, Corsair says its new drives are suitable with its Hydro X Sequence XM2 water block, if you wish to incorporate one into your liquid cooling loop.

The brand new drives are out there now on Corsair’s webstore, priced at $990 for the 4TB mannequin, $400 for the 2TB drive, and $200 for the 1TB mannequin. Not low-cost, although usually consistent with different SSDs in the identical velocity class.
