Perfect if you need this specific type of cable. But it's unlikely that many people will need eSATA since it's almost been abandoned. The main disadvantage of eSATA is that it does not provide the necessary performance for a 2.5 inch external drive such as a USB3.0 SATA adapter. However, I had a desktop from that era, so I decided to test it, but after learning about this limitation, I wasn't worried.
