Mercury Electra 6G

With a sustained read speed of 556 MB/s, OWC’s Mercury Electra 6G SSD is among the fastest SATA III drives in the market, and can be compared to OCZ’s Vertex 3. This SandForce SF-2281 powered drive boasts an Input/Output Per Second (IOPS) of 60,000 at 4k random write. The Mercury Electra contains asycnhronous class A NAND flash modules.

This solid state drive is available in four capacities, namely 60 GB, 120 GB, 240 GB and 480 GB. Both read and write latency are 0.1 ms and data security is ensured through chip-based encryption, 256-bit and 128-bit AES compliant. The drive’s ECC can correct up to 55 bytes in a 512 byte sector. Only 1 sector per 1016 bits read.

Similar to other SandForce powered device, the Mercury Electra supports Redundant Array of Independent Silicon Elements (RAISE) technology which can provide data protection and reliability without any concerns for transfer speed loss. Seven percent over-provisioning is applied for maximizing read and write performance similar to another OWC product, Mercury Extreme Pro. TRIM commands are supported and SMART attributes are standard for this drive. This product is packaged with a warranty of three years.

The OWC Electra 6G displays exemplary performance which, in itself, should make the sale but this company has gone so much further that this becomes a no-brainer. Not only have they hit the ideal in exterior packaging and an amazing design, but they have done something that I don’t think any other has been able to do yet.

macnn:

Now that SSDs with usable capacities no longer cost more than the computers to which they are connected, drives such as OWC’s Electra 6G have become more of a practical storage choice. Users without the need for SATA 3.0 transfer speeds may still be inclined to spend around $100 for a spacious 1TB disk that fits inside a notebook, rather than paying $450 for the 240GB Electra 6G. But for those who regularly utilize data-intensive software for functions such as video or photo editing and gaming, the additional money may prove well spent.

Overall we were pleased with the performance of the Electra 6G. It performed well in the synthetic tests, but it did slip behind the OCZ Agility 3 which is its closest competitor when it comes to our real world benchmarks. Some of these differences we feel are related to firmware, since from a hardware standpoint they both offer nearly identical components.
