About Refurbished Products
SAS is one of two technologies that computers use to transfer data from the motherboard to storage. SAS stands for serial attached SCSI. SCSI stands for small computer systems interface, which is the previously used parallel communication technology. SAS is more expensive and is best suited for heavy computer workstations and servers.
Just like serial advanced technology attachment (SATA), SAS makes use of serial communication, which means that data can be transmitted both ways – from the motherboard to storage and from storage to the motherboard. The benefits of serial communication are the use of smaller cables that allow for increased flexibility in the design of computer architecture. The cables have dividers that will prevent interference by magnetic fields. Serial communication has the added advantage of allowing the storage drive to queue incoming data.
We have SAS cables that are different from SATA cables since they come as a pair. The usual 4 wires are separated into 2 different cables, each with incoming and outgoing wires. The SAS cable ensures that you can connect a motherboard to a storage drive and yet another piece of hardware with SAS connectors.
We have the SAS HDD to help you set up workstations and servers for your office or small business. You can choose from SAS cables and SAS drives as well as other components depending on your unique needs. SAS technology can also be used for personal computers that are used for intensive processing work such as animation, video editing, and visual effects.
Distinguishing characteristics of SAS technology that makes it ideal for servers and workstations
Compared to SATA technology, SAS hard disk is faster in the transfer of data in and out of storage. The most common speed is 7200 RPM and we have the following options 2TB-7.2K RPM, 1TB-7.2K RPM, 4TB-7.2K RPM, and 3TB-7.2K RPM. In some instances, SAS disk drives have comparatively higher RPM such as 300GB-10K RPM, 300GB-15K RPM, 450GB-15K RPM, and 600GB-15K RPM drives. This makes SAS hard drives ideal for servers and workstations that support fast data transfer.
SAS technology is not heavily reliant on storage capacity. Keep in mind that servers may have both SATA and SAS hard drives which mean that they will have the collective storage capacity, unlike PCs that rely on a single hard drive. Additionally, creative professionals use multiple hard drives in their work.
SAS hard disk is more expensive and more durable compared to a SATA drive. The durability of these drives denoted as the meantime before failure (MTBF) is 1.2 to 1.6 million hours of use at about 45°C.
SAS technology enables the integration of hardware useful in servers and workstations. Hard drives with SAS connectors should be housed in SCSI enclosures for ease of management of traffic. The SCSI enclosure programming will help in finding and reporting of hardware errors
One advantage of SCSI programming lies in the use of RAID (redundant array of independent disks) to prevent data loss. SCSI ensures that your data exists on different disks before it is eventually saved. Performing RAID is more efficient when using SAS hard disks compared to SATA technology. RAID technology is absolutely necessary for servers and workstations that undertake numerous transfers of temporary data since it also allows multipath input/output (I/O). SAS technology employs multiple circuitry and that means that data can be rerouted to a secondary circuit if the primary circuit fails.We'll help you choose the best SAS technology components that will optimize their use in servers and workstations right from SAS connectors, motherboards, SAS cables to SAS HDDs. SAS technology is all about prioritizing speed and performance over storage capacity.
