Data; It is one of the most important assets of businesses. And it needs to be available 24/7 for many businesses. Even a system using multiple solid state drive-SSDs with incredibly high performance; may experience data loss or hardware malfunctions that cause the system to stop. This reduces productivity, revenue and customer satisfaction.
Data protection and access to data are becoming increasingly important. Storage subsystems have multiple components; drives, storage controller, motherboard and others, the storage system must be operable even in case of failure of one or more of these components. Many modern motherboards have several SATA controller channels that allow for four, five, six or eight channels, each with a SATA SSD. The drives on these channels can then be combined into a single RAID array. Different RAID controllers suitable for business needs can be installed in PCIe slots. Hardware RAID (hardware RAID) is much faster than software RAID (software RAID) functionality, which is often used in end-user systems.SanDisk SSD
RAID disks (or cheap drives) were developed to help deal with failures in hard disk drives (HDD). The most common configurations are: RAID 0, 1, 0 + 1, 5, and 6. Some configurations offer higher performance than a single drive, while some configurations are for redundancy. All configurations are designed to combine multiple drives as a single virtual partition.
Discover the Power of SSD Drives
Samsung enterprise serial SSD drives have features specifically aimed at improving endurance and data protection.
For example; With the PLP (Power Loss Protection) feature in Samsung SM883, PM883 and PM1725 models, it allows the system to finish writing data to the drive in case of power failure with internal capacitors. In addition, enterprise Samsung SSD drives have higher reliability than consumer-grade SSD drives, along with end-to-end data protection functionality and advanced error correction algorithms.
Low latency, high throughput, and low random access times always ensure that rebuild times are improved for RAID arrays, meaning that volumes get back to configuration as quickly as possible. Choosing the right RAID configuration is also very important. While rebuilding a RAID 5 array created with 5 HDD drives in a drive failure can take hours, the 0 + 1 RAID array created with low latency high speed SSD drives can be rebuilt in minutes Kingston A400 SSD.
The Lifetime Advantage of SSD Drives
Another important feature of SSD drives is their total service life. Unlike HDD-hard disk drives, which often fail due to mechanical problems, SSD drives are purely electronic and generally more reliable. The most common malfunction in SSD drives is due to the wear of individual cells. Each cell on the SSD drive has a limited lifetime. In today's SSD drives, the cell life is quite extended compared to previous generations. Users should pay attention to the drive writes per day - DWPD (Drive Writes Per Day) value when purchasing SSD drives. This value represents an estimate of how many times the drive can completely rewrite each day during the warranty period.
For example: a 960 GB capacity SM883 Server SSD drive with 3 DWPD; For 5 years, it offers 3 x 960 GB = 2880 GB data written and erased every day.
Consumer-grade SSD drives offer values ​​as low as 0.1 DWPD during the 3-year warranty period, while enterprise-class SSD drives such as the SM883 Sunucu SSD offer 3 DWPDs during the 5-year warranty period. Storing critical data on more reliable drives also contributes to overall system reliability.
Keeping data safe requires a versatile approach: backups - backup, partition mirroring, hosting a copy of the data in other data centers or in the cloud - replication. Each approach; The original source depends on the correct writing and safe storage of the data. For this, investing in the most reliable SSD drives available is the ideal solution for businesses, but most IT managers also prefer using RAID to optimize their data storage.
