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

Final Thoughts




The OWC Mercury Electra Max 6G 2TB is a drive that we were excited to review. Over the years, OWC has delivered excellent performing SSDs, and we fully expected this SSD would be no different in that respect. That is until we saw the drive's spec sheet and we realized that the OWC Mercury Electra Max 6G 2TB was a dual SM2246EN controlled SSD with a JMicron RAID controller built-in. And to top it off, that "Tier 1 Major Multi-Level Cell (MLC) High-Performance Sync-NAND Flash" as quoted on the spec sheet, turns out to be lower performing asynchronous MLC flash.



Benchmarking the drive confirmed that this drive is one of the worst performing configurations we've ever seen. Until now, we regarded the BX200 as the worst performing recently introduced SSD, and that is to be expected because it is a TLC SSD equipped with the lowest performing flash on the market. From the moment we booted the Electra Max as our OS disk filled to 75% of its capacity, it was apparent that performance would be lackluster. We were hoping that after a few hours of idle time the drive would become more responsive, but it did not.


We are really at a loss trying to figure out how a drive of this configuration would ever seem like a good idea. OWC's Mercury Electra Max 6G 2TB SSD delivers the lowest overall performance of any SSD currently on the market. The drive has no TRIM support, no queue scaling, no secure erase support, and to top it off, it's priced similarly to Samsung's 850 EVO 2TB which is vastly superior in every aspect. We don't know if performance will be improved through a firmware update, but as it stands, we cannot recommend this SSD.





  • Attractive Enclosure




  • No TRIM Support
  • Sub-Par Performance
  • High MSRP

The Bottom Line: Steer clear of this SSD, it is a pointless configuration that is sure to disappoint all but the most loyal Mac users.
