- Key Specs
- Storage Capacity: 4000 gigabytes (Measured in megabytes (MB), gigabytes (GB) and terabytes (TB), this is the amount available for storing files, music, movies, photos and more. The total includes the capacity of the hard disk drive and solid state drive if both are included on the computer.)
- Storage Drive Type: HDD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Maximum Read Speed: 180 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
- Maximum Write Speed: 180 megabytes per second (The greatest speed at which the device can write information; for example, saving files.)
- Form Factor: 3.5 in.

- Rated 4 out of 5 stars
easy to install
This is my first time using an HDD specifically designed for security cameras. It’s just like a regular SATA HDD, so installation was very easy with no issues at all. I had seen many positive reviews, so despite the higher price, I installed it in two of stores. It’s been less than a week since I started using it, so it’s too early to comment on the pros and cons, but I have high expectations.
