Seagate Portable 2TB External Hard Drive HDD — USB 3.0 for PC

1. Seagate Portable 2TB External Hard Drive HDD — USB 3.0 for PC

  • Brand: Seagate
  • Manufacturer: Seagate

The Seagate Portable 2TB External Hard Drive is an affordable and accessible solution for everyday storage needs. With a lightweight design and plug-and-play functionality, this drive is tailored for users who need simple backups and file transfers. It’s compatible with both Windows and Mac systems, and its USB 3.0 interface ensures decent transfer speeds for a mechanical hard drive. The included 18-inch USB cable and 1-year Rescue Data Recovery Services add to the overall value of this budget-friendly drive.

In terms of performance, the Seagate Portable HDD delivers as expected for its price range. With a rotational speed of 7200 RPM, it offers moderate read/write speeds, making it suitable for storing photos, videos, and documents. However, it’s not ideal for high-speed data transfers or running applications directly from the drive. The portability is a plus, but its mechanical nature makes it less durable compared to SSDs. Users looking for an affordable, no-frills solution for basic storage will find this drive to be a solid choice.

Pros

2. Seagate BarraCuda 8TB Internal Hard Drive HDD – 3.5 Inch Sata 6 Gb/s 5400 RPM 256MB Cache for Computer Desktop PC (ST8000DMZ04/004)

  • Brand: Seagate
  • Manufacturer: Seagate

The Seagate BarraCuda 8TB Internal Hard Drive is a versatile solution for users requiring large storage capacities.

It performs well in sequential read/write tasks, achieving sustained transfer rates of up to 190 MB/s, but falls short in random access scenarios. The lack of included cables or packaging might be a drawback for some users. Overall, this drive is best suited for users prioritizing storage space over speed, such as those managing large media libraries.

Pros

  • Massive 8TB storage capacity
  • Reliable for long-term use
  • Ideal for desktops and gaming PCs
