We are providing specifications below to explain why you should consider purchasing the Seagate 400GB-10K RPM SAS-3GBPS Hard Drive, including a general overview, performance specifications, relevant images, media files, and technical information about the 9EA066-042 compatibility.

More Information

The 9EA066-042 Seagate Cheetah NS 400GB 10K RPM SAS-3GBPS Hard Drive is a high-performance hard drive manufactured by Seagate. The drive has a storage capacity of 400GB and a rotational speed of 10,000 RPM, which is faster than the typical 7,200 RPM found in standard hard drives. This can result in faster data access times, as the drive's read/write head can access data on the platters more quickly.

The drive uses the SAS (Serial Attached SCSI) interface with a data transfer rate of 3 Gbps. SAS interface is faster and more reliable compared to SATA interface, and 10K RPM is faster than 7.2K RPM, which can improve the performance of the drive. SAS interface is typically used in enterprise-level servers and workstations that require high-performance storage.

The Seagate Cheetah NS series is a family of high-performance, enterprise-class hard drives that are designed for use in demanding applications, such as data centers, enterprise servers, and high-performance workstations. The drives are built to provide high reliability and performance, with features such as advanced caching algorithms, and enhanced error correction.

High-speed data transfer

The 9EA066-042 Seagate Cheetah NS 400GB 10K RPM SAS-3GBPS Hard Drive is a high-performance hard drive designed for use in enterprise-level servers and workstations. The drive's performance is influenced by several factors:

Capacity: With a storage capacity of 400GB, this hard drive is relatively small compared to other hard drives on the market. This may not be sufficient for storing large amounts of data.
Rotational speed: The hard drive's rotational speed of 10,000 RPM is faster than the typical 7,200 RPM found in standard hard drives, which can result in faster data access times, as the drive's read/write head can access data on the platters more quickly.
Data transfer rate: The drive has a data transfer rate of 3 Gbps. This is the speed at which data can be transferred between the drive and the computer. A higher data transfer rate can result in faster data transfer speeds, which can be beneficial when working with large files or when copying data to or from the drive.
Interface: The drive uses the SAS interface, which is a faster and more reliable interface compared to SATA. SAS interface is typically used in enterprise-level servers and workstations that require high-performance storage.

Additionally, the Seagate Cheetah NS series hard drives are designed with advanced caching algorithms and enhanced error correction, to provide high reliability and performance. This makes the Seagate Cheetah NS 400GB 10K RPM SAS-3GBPS Hard Drive a suitable option for demanding applications such as data centers, enterprise servers, and high-performance workstations.

General Compatibility

The 9EA066-042 Seagate Cheetah NS 400GB 10K RPM SAS-3GBPS Hard Drive is designed for use in servers and workstations that support the SAS interface. It is not compatible with motherboards or systems that only support the SATA interface.

It is important to check the compatibility of the Seagate Cheetah NS 400GB 10K RPM SAS-3GBPS Hard Drive with your specific server or workstation model before purchasing. You should verify that the system has a SAS interface and is compatible with the drive's form factor, power and voltage requirements, and any other specifications required by the drive.

It's also important to check the firmware and drivers of the system and check if they support the drive. It's always recommended to check with the manufacturer's website or consult with their support team to ensure compatibility.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Serial attached SCSI SAS 3gbps hard drives are commonly used in servers and bring with them immense benefits. However, choosing the right hard drive is very important depending on your projects. Avoid putting greater emphasis on the pricing of the hard drives, since it may lead to a complete disaster.

The preserve of the SAS 3Gbps HDD is in servers and high-end workstations where speed considerations are most important. The hard drives are available as 3.5-inch form factor and 2.5-inch form factor depending on your specific applications. These HDDs will process data and complete reads/writes faster than SATA drives – actually, it takes just a fraction of the time. It makes them ideal for enterprise applications since they perform efficiently, faster, and under rigorous conditions. The faster throughput is the idea behind getting SAS hard drives for your applications, seeing that the latest SAS 12Gbps hard disks are super-fast and incorporate RAID hardware controllers.

The throughput of a SAS 3Gbps disk drive is rated at 300 MB/s. Bandwidth typically represents the theoretical maximum level of data that passes through a channel. On the other hand, throughput is the actual measure of how much data actually travels through the channel successfully. Therefore, bandwidth is a theoretical value whereas throughout is the real value.

The key features and capabilities of the popular SAS 3Gbps HDDs are:

  • Performance – You will benefit from performance levels that reach 3Gbps (300MB/s throughout), full-duplex transmissions, wide ports for aggregated bandwidth, advanced command queuing, and port aggregation.
  • Flexibility – the flexibility of the SAS 3Gbps lies in physical and software compatibility on SATA drives as well as backward-compatibility with SCSI software.
  • Scalability – you cannot go wrong with the broad address range allowing connection to physical devices and external storage systems using the long cables and small connectors.
  • Reliability and availability – you can achieve point-to-point connections, redundancy paths, and dual active port support with the SAS 3Gbps drives.

We have recommended the SAS 3Gbps to a good number of clients since they are best suited for 24/7 workloads. These hard drives are best suited for servers due to the 100% duty cycle. SAS hot-swap hard drives will always win on the reliability front since they are designed to read/write data throughout the day. The SAS 3Gbps HDD cannot be compared to SATA drives commonly used for desktops that have 20-30% duty cycles. Drive speed is a major determinant of throughput and is measured in RPMs whereby SAS drives will operate at between 7200 and 15000 RPM. For better understanding, the faster a drive rotates, the higher the read/write speeds and the higher the throughput. The net effect will apply for slower drive speeds which negatively impact read/write speed and throughput.

The only downside with the SAS 3Gbps hard drives is the storage capacities available. Generally, SAS hard drive disks have a smaller storage capacity format compared to SATA drives. The common storage sizes available for SAS 3Gbps drives include: 73GB-10K RPM, 146GB-15K RPM, 300GB-15000 RPM, 450GB-15K RPM, 600GB-10K RPM, 1TB1TB-7.2K RPM, and 2TB-7.2K RPM which are ideal for servers and high-end machines used for production content.

SAS cables are required for connection and feature a continuous connector for both power and data. The SAS cable cannot be used to connect SATA controllers using a SATA connector since they carry higher power voltages. A distinctive feature of the SAS cables is that they are more than 30-feet in length compared to SATA cables that can only reach a maximum of 3-feet in length. However, it is possible to connect a SAS drive to a SATA controller using a continuous/SAS connector.

We have different specifications of the SAS 3Gbps hard drive which are ideal for high-performance applications and for highly virtualized environments that typically handle critical applications and high volumes of users.
