When it comes to backup performance, every little detail counts. Unfortunately, some companies tend to oversimplify the discussion, focusing only on a handful of key factors. The reality is much more complex, and ignoring the finer points can put data protection at risk.<\/p>\n

In a previous article (\u201cEfficient Backup: Ready for the Black Scenario<\/span><\/a>\u201c), we explored backup methods, the importance of RTO and RPO<\/span><\/a>, and the differences between data storage and backup. But that was just the tip of the iceberg. Now, let\u2019s dive deeper and examine how storage media, network throughput, and data reduction mechanisms impact backup performance. What should you consider when choosing the best solutions for your business?<\/p>\n

Storage Media: A Tough Choice<\/h2>\n

Not long ago, using SSDs in NAS systems (often used for backups) seemed unnecessary. Today, almost every NAS device supports them. One of the loudest voices advocating for ditching traditional hard drives is VAST Data, a U.S.-based company specializing in large-scale data management. Their solution relies entirely on flash storage, offering archive-level data retention at a cost comparable to HDDs. With proprietary technology that extends SSD lifespan to up to 10 years, their systems reduce the need for multiple devices to store and protect data. Perhaps in the future, businesses won\u2019t have to choose between HDDs and SSDs \u2013 but for now, that decision still matters.<\/p>\n

Flash storage significantly boosts backup performance. For example, a standard SATA SSD can be twice as fast as a mechanical SATA hard drive, while NVMe SSDs can outperform HDDs by a staggering 35 times. That\u2019s a game-changer. Yet, many businesses still favor HDDs due to their lower cost. At the start of 2024, a 1TB NVMe PCIe 5 SSD cost around $150 \u2013 the same price as an 8TB HDD.<\/p>\n

With the growing demand for storage-driven by explosive data growth and backup best practices<\/span><\/a> (3-2-1, 4-3-2, 3-2-1-1-0) \u2013 choosing the right media is critical. Many experts argue that hard drives remain more reliable and predictable, while SSDs, despite improvements, can still experience unexpected failures.<\/p>\n

But HDDs and SSDs aren\u2019t the only options. Tape storage remains in play, offering a much cheaper alternative to HDDs for long-term archival. However, HDDs are far superior for short-term storage and incremental backups. Speed is also a factor \u2013 HDDs provide faster data access compared to tape, where retrieving data can take minutes due to loading and rewinding times. Restoring a large file system from 30 tapes could add up to two hours of delay, whereas HDDs work instantly.<\/p>\n
