OWC’s Aura Professional IV NVMe SSD is a pretty quick NVMe SSD. Having said that, at $299, the 2TB model we examined, even though not the priciest leading-tier push (Seagate’s FireCuda 530 was over $350 at the time of this writing), is not the lowest priced either. Samsung’s 980 Professional is a great $70 more cost-effective at the second, and WD’s wonderful Black SN850X is also a few of 10-places a lot less.

Lowest priced or not, the Aura Pro IV turned in an extraordinary efficiency in our suite of storage assessments.

OWC Aura Pro IV: Structure and functions

Sporting the popular 2280 (22x80mm) type component, the Aura Pro IV is a PCIe Gen four, 4-lane (x4) SSD leveraging an Innogrit Rainier IG5236 controller, 1GB of SK Hynix DRAM for each 1TB of capacity, and 176-layer Micron TLC (Triple-Degree Cell/three-bit) NAND. In addition to the 2TB/$299 model, the drive can be located at 500GB/$seventy nine and 1TB/$169 capacities as nicely.

The Aura Professional IV ships with out a warmth sink, but there are very couple apps in which you want one particular. Additionally, most gaming and prosumer motherboards give their personal, so even if you’re a person who’ll be stressing their storage, you are very likely already established in that regard.

OWC warranties the Auro Professional IV for five a long time, or 250TBW (terabytes that might be written) for every 500GB of capability. That’s a little bit higher than the norm, and significantly extra than WD delivers with the speedy Black SN850X, albeit a little bit considerably less than Seagate grants for its FireCuda 530.

Beware the SKU on utilised drives

There is 1 matter you have to have to search out for if you’re not shopping for the Aura Pro IV from OWC, or new (design OWCS3DIG3P4T20). There is a incredibly comparable, but much slower SKU (OWCS3DIGP4XT20—note the X and absence of a next 3) that might pop up applied, or some such. I analyzed just one of these in the OWC’s Ministack STX exterior drive enclosure—and when it browse as fast as the Aura Professional IV, create speeds ended up about 50 percent. Examine the product amount carefully if you see a fantastically lower value on a new or used Auro Pro IV.

OWC Aura Pro IV: General performance

If you complete the CrystalDiskMark eight sequential go through and publish final results right underneath, the Aura Professional IV actions a hair more quickly than the prime-rated FireCuda 530. Sweet.

Having said that, via all the phases of CrystalDiskMark eight, it’s just the sixth swiftest travel we’ve analyzed. A comparatively shut sixth in a pack with really similar quantities, but however sixth. The Editor’s Alternative FireCuda 530 continues to be numero uno. Be aware that most of the Aura Pro IV’s deficit was in one-thread/one queue checks.

This is the sum of all CrystalDiskMark’s sequential and random checks. It offers you an strategy of how very good an total performer every single push is.

Inspite of being a little bit off the speed with reduced thread and queue counts, the Aura Pro IV’s real-planet overall performance underneath Home windows is stellar. It lagged at the rear of the FireCuda 530 by a measly 2 seconds in our 48GB transfers—statistically insignificant and inside of the margin of error.

The Aura Professional IV still left absolutely nothing to be desired in our true-globe 48GB transfers. Shorter bars are greater.

Even greater, the Aura Professional IV turned the tables on the FireCuda 530 in our 450GB single-file write. Its time of 210 seconds is just a one 2nd off the non-RAID history of 209 held by the Teamgroup Cardea A440 Pro.

The Aura Pro IV also excelled at long transfers, slipping a mere 2nd guiding the all-time report.

Be aware that Windows file copying routines on their own amount the actively playing discipline rather in our authentic-entire world transfers. Some apps (including the artificial benchmarks) and techniques can attain drastically better numbers by undertaking their individual I/O. If you on a regular basis use a application that performs its have I/O, a far more pricey travel can be really worth the premium. Microsoft’s Direct Storage may impact this at some stage.

Duplicate tests make use of an ImDisk RAM disk applying 58GB of the 64GB total memory.

Each and every examination is performed on a freshly formatted and TRIM’d travel so the results are optimum. Over time, as a push fills up, functionality will lessen thanks to fewer NAND for caching, and other components. The functionality numbers shown use only to the travel of the potential tested. SSD functionality can range by capability thanks to more or fewer chips to shotgun reads/writes throughout and the amount of money of NAND obtainable for secondary caching.

Bottom line

The Aura Pro IV is a good PCIe 4 NVMe SSD. The only problem is that it’s competing in a sea of equally wonderful drives. Irrespective, taking into consideration the in general general performance and higher TBW rankings, it should really absolutely be on your top-tier limited checklist.
