OWC Mercury Electra MAX 6G 2TB SATA III SSD Review

TweakTown Rating: 50%Manufacturer: OWC



Version and / or Patch Used: 3.05


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.





Compressible sequential read/write transfers max out at 529/477 MB/s. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. These figures are both higher than OWC's stated performance figures, but that's because those given by OWC are for sustained (steady-state) performance.


Sequential Write




The Samsung drives win this test. The Reactor and TeraNova both deliver better small file write performance up to 32K than the OWC Mercury Electra MAX 6G 2TB or "Electra Max" as we will refer to it going forward.


Sequential Read




The Electra Max lags behind the rest of our test pool from start to finish. The Reactor and TeraNova are both SM2246EN powered drives with MLC flash, and they both handily outperform the Electra Max. This is exactly what we saw at CES, standard (meaning one controller) SM2246EN powered SSDs handily outperform the dual controller configuration that is the Electra Max.



Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.








Anvil's scoring gives a good indication of a drive's overall performance. This score indicates that the Electra Max is at best, a sub-par performing SSD. Even the lowly BX200 eviscerates the Electra Max.


(Anvil) Read IOPS through Queue Depth Scale




This chart shows exactly why we chose our test pool the way we did. Samsung's 2TB drives are the best performing SATA SSDs on the market, both capable of delivering up to 10x the performance of OWC's Electra Max 2TB. We will point out that Samsung's 2TB 850 EVO is currently available for $604.


The Reactor and the TeraNova are both standard SM2246EN powered, and they are delivering up to 7x the performance of the Electra Max. The BX200 was up until now the worst performing recently released SSD on the market. All of this taken together goes back to the question we asked ourselves at CES; WHY? Why would anyone choose this path to more capacity? As we see it, bridging two good controllers with quite possibly the worst RAID controller on the market is not a good recipe.


(Anvil) Write IOPS through Queue Scale




Write performance is no different. The Electra Max is again overmatched.
