Here are some of the key features of the Dell 2TB 7.2K RPM SAS 3.5 Inch Server Hard Drive:

• 2TB storage capacity: This hard drive provides plenty of storage space for even the most demanding applications.
• 7200 RPM rotational speed: This fast rotational speed allows the hard drive to quickly access data, which is essential for performance-critical applications.
• SAS 12Gb/s interface: This high-speed interface provides the bandwidth needed for high throughput applications.
• Advanced format 512n: This format improves data density and performance.
• Hot-swappable: This feature allows the hard drive to be replaced without powering down the server.

Dell 2TB 7.2K RPM SAS 3.5 Inch Server Hard Drive is a reliable and high-performance hard drive that is ideal for use in servers. It is backed by a one-year warranty from Dell.

Here is the difference between 2.5 and 3.5 SAS hard drives:

• Size: 2.5 SAS hard drives are smaller than 3.5 SAS hard drives. This makes them more portable and easier to install in laptops and other small devices.
• Storage capacity: 3.5 SAS hard drives typically have a higher storage capacity than 2.5 SAS hard drives. This is because they can be physically larger and have more platters.
• Performance: 3.5 SAS hard drives typically have better performance than 2.5 SAS hard drives. This is because they have a faster rotational speed and a wider data interface.

In general, 3.5 SAS hard drives are better for applications that require high performance and storage capacity. 2.5 SAS hard drives are better for applications that require portability and a smaller form factor.
