OWC Mercury Electra MAX 6G SSD Review (2TB)

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Again, during Crystal Disk Mark we can see the OWC Mercury Electra 6G MAX does better than its rated specs. Sequential speeds reach 522MB/s read and 491MB/s write while 4K performance is about average reaching 36MB/s read and almost 100MB/s write.

AS SSD BENCHMARK VER 1.8

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD this SSD reaches an overall score of just 422 points! This is obviously due to very poor high queue depth performance. Sequential speeds reach 490MB/s read and 440MB/s write. 4K read comes in at 32MB/s while write is a bit slower at 83MB/s. Looking at the IOPS results, it is sad to see that this drive is not able to achieve anywhere near its rated spec of 60K IOPS. Let’s move on to Anvil and see if it does any better there.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

Again, results are in line with what both CDM and AS SSD have been showing. We see decent sequential and QD1 4K performance, but at higher queue depths performance is not where it should be. Overall, it reached a total score of 2,971 points, which is half that of most performance SSDs.

What a pointless config. Not only this is more expensive to make, it’s slower than using a single controller.

They should have just went with Phison S10, which natively supports 2TB of storage and is faster than this.

From OWC Mercury Electra 6G I learned that ‘SSD’ actually stands for “Super Sudden Death”. I lost all my stuff, because it died right in the middle of backup. Thank you ‘OWC’. No more anything from OWC in my MBP 13″ late 2011. Never ever!
