Product Overview of Seagate Hard Drive
The ST3500320NS Barracuda is a type of hard disk drive (HDD) that was made by Seagate, one of the leading companies in the storage industry. This particular hard drive has a storage capacity of 500GB (Gigabyte) and spins at a rate of 7200 Revolutions Per Minute (RPM). It uses a Serial Advanced Technology Attachment (SATA) interface to connect to the computer, and has a 32MB buffer. It also has a 3.5-inch form factor and a low profile design, making it easy to fit into most computer systems.
One of the most important features of any hard drive is its storage capacity. The ST3500320NS Barracuda has a capacity of 500GB, which means it can store up to 500 billion bytes of data. This is equivalent to approximately 100,000 songs, 250,000 photos, or 100 hours of high-definition video. The storage capacity of a hard drive is important because it determines how much data you can store on your computer. If you have a lot of files, such as photos, videos, or music, you will need a larger capacity hard drive to store all of your data.
The spindle speed of a hard drive is the rate at which the disk inside the drive spins. The ST3500320NS Barracuda has a spindle speed of 7200 Revolutions Per Minute (RPM), which is a common speed for desktop hard drives. A faster spindle speed can improve the performance of the hard drive, as data can be read and written to the disk more quickly. However, a faster spindle speed can also generate more heat and noise, which can be a concern in some computer systems.
Interface & Buffer
The interface of a hard drive is the type of connection it uses to communicate with the computer. The ST3500320NS Barracuda uses a Serial Advanced Technology Attachment (SATA) interface, which is a standard interface used by most modern hard drives. SATA interfaces are faster and more reliable than older interfaces, such as Parallel ATA (PATA). They also use smaller cables, which makes them easier to install in tight spaces.
The buffer, also known as the cache, is a small amount of memory that is built into the hard drive. The ST3500320NS Barracuda has a 32MB buffer, which is a common size for desktop hard drives. The buffer is used to temporarily store data that is being read from or written to the hard drive. This can improve the performance of the hard drive, as data can be transferred more quickly between the hard drive and the computer.
The form factor of a hard drive refers to its physical size and shape. The ST3500320NS Barracuda has a 3.5-inch form factor, which is a common size for desktop hard drives. This size is larger than the 2.5-inch form factor used by laptop hard drives. The larger size allows for larger storage capacities and faster spindle speeds. The ST3500320NS Barracuda also has a low profile design, which means it is thinner than some other 3.5-inch hard drives. This can be useful in computer systems where space is limited.
Internal vs. External
The ST3500320NS Barracuda is an internal hard drive, which means it is designed to be installed inside a desktop computer. Internal hard drives are usually faster and more reliable than external hard drives, as they do not have to rely on a separate interface to communicate with the computer. However, internal hard drives can be more difficult to install and may require some technical knowledge.

About Refurbished Products
Serial advanced technology attachment denoted as SATA or Serial ATA, or S-ATA is a computer bus interface mostly connecting host bus adapters to mass storage devices including hard drives. It is the most commonly used technology to connect hard drives to a PC's motherboard.
There have been multiple versions of the SATA interface developed to meet the need for increased storage capacity and bandwidth. The SATA technology was first introduced in 2000 to replace ATA and PATA to provide faster data transfer rates and hot-swapping. Advanced host controller interface (AHCI) is the standard interface for SATA which supports hot swapping and native command queuing (NCQ). Hot swapping refers to the ability to replace components of a computer system without having to shut down the entire system. NCQ allows improved performance through the ability to augment the orders of implementation of reading/writing commands. That means commands will be rescheduled and permits the host to send more commands to the hard drive as it searches data for another command. The 6Gbps data transfer throughout makes it superior to previous technologies such as ATA and PATA. SATA is able to run in IDE emulation mode, but it will not support advanced features.
We have helped all our clients across the board to understand how the technology works with HDDs, SSDs, and modules by knowing the specifications of the different SATA versions. A good grasp of these versions of SATA helps in the identification of the right storage capacity options for your application.
SATA II HDD generation or SATA 2.0 of the SATA technology is part of a series of revisions that happened in 2003, 2004, and 2008 that culminated in SATA III or SATA 3.0. With every revision, there was an increase in speed and additional features that support speed and allow for reliable storage drives. However, the physical appearance of the SATA connector was not altered. SATA III is the most commonly used SATA interface and has been through five revisions from 3.1 to 3.5.
SATA II hard disk was previously referred to as SATA 3Gbps which reflected its speeds. This second generation of the SATA technology has a SATA interface with 3Gbps transfer speed and a bandwidth throughput of 300MB/s. The following are SATA II drives you can choose from depending on specific needs: 2TB-5.4K RPM, 2TB-5.9K RPM, 3TB-7.2K RPM.
Notable features of SATA II include:
- Hot plugging – refers to the ability to change a drive as the computer runs.
- Staggered Spin Up – refers to the ability to start disk drives in sequence to ensure even power load at the start of the system.
- Native command queuing – SATA 2.0 drives have an in-built algorithm that chooses the most efficient order to execute commands to improve performance and efficiency. The feature helps to reduce mechanical overhead and improve performance.
- Port multipliers – this help to connect as many as 15 drives to a SATA controller. This feature facilitates the easier building of disk enclosures using SATA drives.
- Port selectors – the feature allows the connection of two hosts to one drive. It helps create redundancy in the drive connection which is very critical in enterprise environments. That means if one of the hosts experiences failure, the second host will take over thereby ensuring continued access to storage.
All SATA generations are compatible both forward and backward. It, therefore, means that SATA II hard disk is backward compatible to function with SATA I ports. Likewise, SATA III is compatible backward to function with SATA I and SATA II ports. In backward compatibility, the maximum speed of the drive will slow down in line with the speed limitations of the port it is connected to. The same is true for lower SATA generations being compatible with higher SATA generations but are limited to their inbuilt speeds.
For users seeking greater speeds than the SATA III limits at 1.5Gbps, 3Gbps, and 6Gbps, there are M.2 and NVMe drives that offer greater performance. These drives have no limitations and will perform more efficiently and are chosen by users focused on speed and performance above everything else.
We have different motherboards with SATA connections and more particularly with SATA II connections and will come with a few SATA cables for the connections that you will use to build a new rig or do upgrades on a rig. Choose from the wide range of SATA cables dependent on what you need and especially when upgrading an older hard drive or other components on your computer. To ensure that you achieve enhanced speeds and performance, you need to buy SATA cables and adapters for compatibility. It may help to depend on your profile and budget to get the latest SATA III standard.
You can fully trust our team to walk you through the options available with SATA II technology and help you choose the best storage for your applications.
