eSATA

• The external hard drive may take longer to transfer data from the PC because it is not always compatible with eSATA technology. The eSATA interface can transfer data at a faster rate than the average cable provided with the external hard drive. Users wanting to take advantage of this have to purchase an eSATA cable separately, and even then, not all eSATA interfaces are easy to use because of the format of the Seagate hard drive.
  
  

Features

• While the external hard drive is compact and easy to use, there are some features that could make it even more user-friendly. It does not contain a power switch, so you cannot leave the external hard drive connected to your computer at all times. To do so would mean running a program, and an overload of open programs and applications on your computer could cause malfunction and delay issues. You will have to manually connect and disconnect the external hard drive when you are finished with it.
  
  

Backups

• The external hard drive also does not perform backups automatically. This means that you will have to manually prescribe a backup to ensure that your data and documents are backed up from time to time. This is a time-consuming process and requires you to keep track of what data was backed up and on what date.
  
  

Multiple Hard Drives

• Users that require a second external hard drive may experience problems locating a driver for it. The first external hard drive is recognized when connected to the PC, but the second drive is not always recognized and may involve the installation of a separate driver, which can cause confusion over which drive to connect to.
