SAS-6GBits (Serial Attached SCSI) is a technology used in modern hard disk drives that provides high-speed data transfer rates and enhanced reliability. It is a standard for connecting computer storage devices, such as hard disk drives and solid-state drives, to the rest of the system.
SAS-6GBits is the latest version of the SAS technology, providing a data transfer rate of 6 gigabits per second (Gbps), which is twice as fast as the previous version, SAS-3GBits. This increased data transfer rate allows for faster access to data stored on the hard disk drive.
In addition to speed, SAS-6GBits also offers several other benefits, including improved reliability and data integrity. It features advanced error-correction capabilities and supports hot-plugging, which allows for the replacement of failed drives without having to power down the entire system.
SAS-6GBits also supports a variety of RAID configurations, which provide redundancy and data protection by mirroring data across multiple drives.
RAID (Redundant Array of Independent Disks) support and benefitsRAID (Redundant Array of Independent Disks) is a technology that allows multiple hard disk drives to be combined into a single logical unit. RAID provides increased data reliability, fault tolerance, and performance, and is commonly used in server and storage systems.
RAID works by storing data across multiple hard drives, which provides redundancy and protects against data loss in the event of a hard drive failure. There are several different RAID configurations, each with its own advantages and disadvantages:
- RAID 0 - Provides improved performance by striping data across two or more hard drives, but offers no data redundancy.
- RAID 1 - Provides data redundancy by mirroring data across two hard drives, but does not improve performance.
- RAID 5 - Provides both data redundancy and improved performance by striping data across multiple hard drives and using parity information to protect against data loss.
- RAID 6 - Similar to RAID 5, but with an additional level of redundancy to protect against the failure of two hard drives.
- RAID 10 - Combines the benefits of RAID 1 and RAID 0 by mirroring data across multiple sets of striped hard drives.
MTBF (Mean Time Between Failure) is the average number of hours that a product or system can function without failure. Error correction systems are designed to identify, detect, and correct errors in a system, improving system reliability and performance.
Error correction features can be implemented using various coding techniques, such as Hamming codes, CRC codes, and BCH codes. These codes are used to detect, identify, and correct errors in a system. Hamming code, for example, is a type of error-correcting code that adds a number of parity bits to a word before sending it. These parity bits help to detect, identify, and correct errors that occur during transmission.
CRC codes are used to check for errors by calculating a checksum for the data being sent. A checksum is a number derived from the data that can be used to detect errors. BCH codes are also used to detect and correct errors. These codes use polynomial equations to detect errors and then correct them.
In conclusion, MTBF measures the average number of hours a system can function without failure, while error correction systems are used to detect, identify, and correct errors in a system. Error correction features can be implemented using various coding techniques such as Hamming codes, CRC codes, and BCH codes.

What is not covered by our warranty?
The reason why our warranty does not cover any problem caused by the following conditions:
(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;
(b) any misuse outside the instructions in the user manual for any specific product;
(c) damaged caused by other hardware or equipment. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
Final Sale items are non-returnable/refundable in any situation. Any question? please ask our team before the shipment.
