Built with the Mercury Electra 3G SSD model featuring industry leading SandForce® DuraClass™ Technologies:
  • DuraWrite™ extends the endurance of your Solid State Drive (SSD).
  • Intelligent Block Management & Wear Leveling automatically distributes data evenly across the entire SSD.
  • Intelligent Read Disturb Management spreads the active read/write across the flash components eliminating data corruption caused by constant use.
  • Intelligent "Recycling" for advanced free space management gradually re-writes data across the SSD over time to ensure data never gets corrupted.
  • RAISE™ (Redundant Array of Independent Silicon Elements) protects the data on your drive similar to having a RAID setup.
  • Best-in-Class ECC Protection for longest data retention and drive life.
High Performance Dual Drive, Bus-Powered Hardware RAID Data Storage/Backup with Plug & Play Convenience
With your choice of two 2.5″ Serial ATA (SATA) hard drives OR Solid State Drives (SSD), the latest Oxford chipset, and USB 2.0/FireWire 800/400/eSATA connectivity, the Mercury Elite Pro Dual mini Portable storage solution delivers up to 300MB/s data transfer speeds for demanding data storage and backup needs. All that performance resides in an impact resistant, bus powered (no AC adapter required), heat dissipating 5.6 in (D) x 6.1 in (W) x 1.1 in (H) brushed aluminum enclosure with near silent, fanless operation.
When you want high style in high performance storage, look no further than the Mercury Elite Pro Dual mini
With the highest quality drive mechanisms built into a shock resistant, portable aluminum enclosure, the Mercury Elite Pro Dual mini is ready to go wherever you need a near silent, compact A/V, Digital Photography, Professional Music, Graphics, General Data, and Time Machine ready Hardware RAID storage solution.
HD Video Certified
This model is pre-configured for RAID-1 but can be user re-configured at any time for RAID-0, Span or Independent. Test Certified for HD Video capture and playback of HDV, DVC Pro, and ProRes 422HQ file formats via eSATA and FireWire 800.

RAID 0 Performance Stripe
Both drives are combined together to create a single drive volume that's much faster and provides larger capacity.

RAID 1 Mirror
Both drives are used to write two "mirrored" copies of your data at the same time to provide an instant backup copy of your data.

NRAID (Span)
Creates a larger drive by combining the capacity of two or more drives of the same or varying sizes into a larger drive volume.

Independent Mode (JBOD)
Available as an option via USB and FireWire connections, this mode lets you access each drive as an independent volume. This mode is like having two separate drives connected to your computer.

    Release Candidate (RC) firmware set

    There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

    Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

    It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

    2. In terms of standard gigabytes, 1GiB ≈ 1.074GB and refers to the actual formatted capacity of shown under Mac OS 10.5 or earlier and Microsoft Windows OS.
    3. Specific application environments such as temperature and duty cycle will affect the overall reliability.
    4. Specifications provided by SandForce.
    5. Temperature reporting is currently an unsupported feature because due to the operating characteristics of SSDs, it is highly unlikely one would ever exceed an OWC Mercury SSD's stated operating temperature ceiling of 158F/70C. However, we are looking into supporting this feature in the future via a firmware update. Firmware updates can be found here: http://eshop.macsales.com/tech_center/OWC/SSD.

OWC 3 Year Solution Warranty

The best warranty is one you never have to use, but should the need occur - OWC is proud to provide a superior level of support and warranty coverage to our customers. Even when not used, we understand the peace of mind afforded by a longer warranty period. OWC's industry leading coverage is a testament to our confidence in the reliability of the solutions that we offer. OWC solutions are engineered to demanding quality standards in order to deliver the most reliable, highest performance available on the market in each storage category.

View more information about the OWC 3 Year Solution warranty

Note: Because the OWC Mercury Elite Pro Dual mini offers three selectable RAID levels, your warranty coverage remains intact if you open the back plate to access the RAID dip switches only. For instructions on changing the RAID level from the preconfigured factory setting, please refer to the product manual.

Do not further disassemble or otherwise remove any components, including the drive mechanisms, on this OWC storage solution prior to the conclusion of OWC's 3 year Warranty period. Doing so will void the remainder of the OWC warranty.

**all of these solutions have a 3yr warranty and there is no separate warranty on the SSDs - no different than our other solutions that have the RE model SSDs... After 3yrs, warranty is up... Why pricing can be less than buying 2 x RE400s or 2 x RE200s alone...**

IMPORTANT LAPTOP USER NOTE: There have been reports of system hangs in relation to hibernation mode. We recommend not using ANY program that puts your laptop into hibernation mode when using an SSD.

Normal, automatic sleep mode functions perfectly with no issues.

We also highly recommend you avoid draining your battery completely (5% or less remaining charge) to avoid being automatically switched into hibernation mode by your machine's power saving settings. If your notebook does go into hibernation mode, the machine can hang once it is plugged into an outlet or when using a charged battery as the machine comes out of hibernation mode. If you should experience this, you will need to restart your machine and any unsaved work from that session will be lost. SandForce is working on this issue and it will be addressed in a future firmware update. We will post the update on our firmware update page as soon as it becomes available.
