About Seagate External Hard Drives & SSDs

Established in 1979, Seagate Technology is one of the world's leading hard drive manufacturers. With one billion hard drive products sold, it claims that it's the number one sales company in terms of drive product sales.

At present, Seagate’s main products include desktop hard drives, enterprise hard drives, laptop hard drives and micro hard drives. In this part, I will introduce Seagate external hard drives and SSDs designed for individual customers.

Seagate external hard drive and SSD products include the following series:

1. Seagate Ultra Touch Family

This series offers USB-C and USB 3.0 compatibility for quick connections, an array of easy-to-use backup software tools for backup on demand with one click, and a file mirroring folder for easily syncing files across devices.

In addition, this series also offers you 1-year Mylio Create plan and four-month Adobe Creative Cloud Photography plan so that you can protect, edit, share, and sync photos across multiple devices easily. It also provides you with Rescue Data Recovery Services, so you can easily defend against data loss and retrieval costs when the unexpected happens.

Ultra Touch external drives have both HDDs and SSDs. There are some differences between the Ultra Touch HDDs and Ultra Touch SSDs, for example:

  • The max speed of the Ultra Touch HDD is 120MB/s, while that of Ultra Touch SSD is 400MB/s.
  • The HDD supports password protection and AES-256 hardware encryption, securing your data (the SSD doesn't have this).
  • The HDD supports Windows, Mac, and Android, while the SSD only supports Windows and Mac.

2. Seagate One Touch Family

Like Ultra Touch drives, One Touch drives also offer backup features, 1-year Mylio Create plan, four-month Adobe Creative Cloud Photography plan, and Rescue Data Recovery Services. In addition, this series also has both SSDs and HDDs.

The One Touch HDDs offer storage capacity up to 5TB and are compatible with USB 3.0 interface. As for the One Touch SSDs, they have speeds up to 1030MB/s and are compatible USB 3.2 Gen 2 (USB-C) and USB 3.0.

3. Seagate Expansion Family

This series has three sub-series: Expansion SSD, Expansion Portable, and Expansion Desktop. The Expansion SSDs offer storage capacity up to 1TB and speeds up to 400MB/s. the Expansion Portable drives offer storage capacity up to 5TB, while the Expansion Desktop drives offer storage capacity up to 16TB.

This series uses USB 3.0 interface and is compatible with both Windows and MacOS. But unlike Ultra Touch and One Touch, the Expansion drives only offer Rescue Data Recovery Services.

4. Seagate BarraCuda Fast SSD

This series uses USB-C interface and has capacity up to 2TB and speeds of up to 540MB/s. With this series, you can boot games faster, transfer files seamlessly, and stream stored videos to your computer without lag.

In addition, it offers backup features, two-month Adobe Creative Cloud Photography plan, and Rescue Data Recovery Services.

5. Seagate Backup Plus Portable Drives

This series also has two sub-series: Slim and Portable Drive. The two subseries have no difference except for the capacity. The Slim series offers 1TB and 2TB drives, while the Portable Drive series offers 4TB and 5TB drives.

This series has no SSD option. Therefore, it has no advantages in speed. But it offers backup features, Mylio Create and Adobe CC Photography Plan, both Windows and MacOS support, and USB 3.0 and 2.0 compatibility.

6. Seagate Photo Drive

Seagate Photo Drive is a 2TB external HDD with USB 3.0 port. It supports both Windows and MacOS, and offers 3-year Mylio Create Plan, 2-year limited warranty, and Rescue Data Recovery Services. In addition, you can easily, quickly and safely back up all of your photos and automatically sync up to four computers and an unlimited number of phones and tablets.

7. Seagate Basic External Hard Drive

If you just want an external hard drive and don't want to other services, you can buy Seagate Basic external hard drives. They use USB 3.0 interface and offer storage capacity up to 5TB.

8. Seagate Backup Plus HUB

Like Expansion Desktop drives, Seagate Backup Plus HUB drives offer storage capacity up to 16TB, use USB 3.0 interface, and have speeds up to 160MB/s. But the Backup Plus HUB drives offer backup software and other services.

In addition, they are equipped with two integrated USB ports on the front, so you can back up your files, precious photos and videos while connecting to and recharging your tablet, smartphone or camera.
