The ST3400620NS Seagate 400GB II-SATA 16MB 7.2K Internal Hard Drive is a consumer-grade hard drive with a storage capacity of 400 GB. It uses the SATA II interface, which provides a maximum data transfer rate of 3 Gbps, and features a 16 MB cache, which is used as a buffer for frequently accessed data. The drive also has a rotational speed of 7,200 RPM, which is a standard speed for consumer-grade hard drives.
The drive is designed for use in personal computers and consumer devices, such as desktop PCs and laptop computers. This drive is not designed for enterprise use and does not have the same level of durability and performance as an enterprise-grade drive, but it can be an affordable solution for consumer storage needs.
The drive is relatively old, it is from 2008-2009. It's performance is not as good as the current consumer-grade hard drives available in the market. However, it can still be used as secondary storage for a consumer device, or as a low-cost solution for storing less frequently accessed data.
The drive supports the standard AHCI (Advanced Host Controller Interface) command set and it also has the SMART (Self-Monitoring, Analysis and Reporting Technology) built-in, which allows the operating system to monitor the drive's health status. Additionally, the drive supports ATA Security Mode Feature Set and Seagate G-Force Protection, which provides protection against handling damage.
The ST3400620NS Seagate 400GB II-SATA 16MB 7.2K Internal Hard Drive is a consumer-grade hard drive designed for use in personal computers and consumer devices. It has a storage capacity of 400 GB and a rotational speed of 7,200 RPM.
In terms of performance, the drive's rotational speed of 7,200 RPM allows it to access data relatively quickly, which can lead to improved overall system performance, faster boot and application load times, and faster data transfer speeds when compared to 5,400 RPM drives.
The drive also has a 16MB cache, which acts as a buffer for frequently accessed data. This can also improve performance by allowing the drive to access the data more quickly.
The drive's SATA II interface provides a maximum data transfer rate of 3 Gbps, which is slower than the SATA III 6 Gbps interface found in most current consumer-grade hard drives. This means that the drive will have slightly slower data transfer speeds when compared to more recent hard drives.
However, it's important to keep in mind that the ST3400620NS Seagate 400GB II-SATA 16MB 7.2K Internal Hard Drive is an older drive, it was released in 2008-2009 and its performance may not be as good as current consumer-grade hard drives. It is not designed for high-performance or high-reliability applications and it might not be suitable for use in applications that require high-performance or fast read/write speeds.
Serial Attached SCSI (SAS)The obvious next step for SCSI, maintaining both the serial physical connection interface and the long-standing software advantage. The importance of aspects like increased capacity, greater density, security, scalability, and accessibility is greater than ever as business storage requirements rise and become more complicated. Enterprise data centers must be operational at all times in order to serve several simultaneous user demands, allow for continual development and expansion, and be maintained. Serial Attached SCSI (SAS), which offers the best performance, satisfies all of these requirements.

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 need: 1.5TB-5.4K RPM, 1.5TB-5.9K RPM, 1.5TB-7200 RPM, 160GB-5.4K RPM, 160GB-7.2K RPM, 1TB-5.9K RPM, 1TB-7.2K RPM, 200GB-7.2K RPM, 250GB-5.4K RPM, 250GB-5.9K RPM, 250GB-7.2K RPM, 2TB-5.4K RPM, 2TB-5.9K RPM, 2TB-7200 RPM, 300GB-10K RPM, 300GB-7.2K RPM, 320GB-5.4K RPM, 320GB-7.2K RPM, 3TB-7.2K RPM, 400GB-7.2K RPM and 360GB-7200 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 starting 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 – these 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 to 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 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.
