Important: To ensure compatibility with the 2009 and 2010 21.5" or 27" iMac, the replacement hard drive must be of the same brand as the original. The model number of the hard drive does not matter as long as the brand matches. 2011 and up iMacs cannot be supported by us.
This drive offers 4 terabytes of storage space for your desktop computer while performing well above other 4TB 3.5" drives.
Hybrid technology from Seagate combines SSD and traditional hard drive technology to provide SSD speeds from an affordable high capacity hard drive. Adaptive Memory technology keeps the files and file types you access the most ready and available for instant transfer from SSD.
No software or operating system requirements, Adaptive Memory technology is self-contained and works like any SATA drive.
