Product Description

MERCURY ELECTRA 3G SSD: The Best Choice SSD for Your Mac with SATA 3Gb/s.

Whether it’s replacing a factory SSD or hard drive in a legacy Mac, or adding a new 2.5″ SSD to your system, Mercury Electra 3G offers a fantastic upgrade, delivering superior performance and reliability. Designed for Mac first, Mercury Electra works without complications right out of the box. No drivers, extra software or workarounds are required, it’s as easy as plug and play. Mercury Electra features premium-quality tier-1 async NAND, and a suite of controller technologies designed to maximize performance and longevity. With exceptional wear-leveling and block management, gold-standard compression and data distribution, best-in-class error correction, intelligent recycling, and requiring no external TRIM support, Mercury Electra 3G SSDs deliver incredible performance and dependability.

The Mercury SSD line features a suite of industry leading controller technologies for performance and reliability:

Global wear leveling algorithms automatically distribute data evenly and manage program/erase count, maximizing SSD lifespan. StaticDataRefresh manages free space, gradually refreshing data across the SSD over time, preventing data corruption. Hardware BCH ECC corrects errors up to 66-bit/1KB for superior data retention and drive life. Advanced security protocols support 128/256-bit-AES disk encryption.

This internal 2.5″ SATA SSD delivers outstanding transfer speeds, endurance, and reliability. With sustained reads up to 250MB/s and writes up to 230MB/s, the OWC 1.0TB Mercury Electra 3G SSD line delivers unbeatable performance. A 7% over provisioning set-aside further ensures exceptional long-term reliability, performance consistency, and durability with an amazing 960GB of visible storage capacity after over provision. 

Replace your conventional hard drive with a reliable solid state drive. Unlike traditional hard disk drives, OWC SSDs have no moving parts, resulting in a quiet, cool, highly rugged storage solution that also offers near instantaneous system response.

Includes 7 mm to 9.5 mm Adapter / Spacer
Attach this adapter to the top of any 7mm, 2.5-inch drive for installations that require a 9.5mm drive height for proper use, whether you need a 9.5mm drive height for a dock, camera, server, device, PC, or external drive. This adapter is not needed for 2.5-inch drive installations that use the standard side or bottom mounting positions to secure the drive in place, and is not needed for any installation of a 7mm drive in Apple Macintosh computers.


This OWC SSD Model is compatible with nearly any Mac or PC model with a Serial ATA connection (SATA, SATA 2.0, or SATA 3.0) including:
