Choosing the Best Rackmount NAS: Things to Consider
So, what do you need to look for when you’re buying a rackmount NAS for your business?
A rackmount NAS is designed to be expandable and flexible to accommodate a company’s growing needs. Still, looking at just how many drives your chosen model can handle is essential since this can determine just how far you can expand your company’s system later on.
For example, some models have only a single disk bay, while others can have as many as 16 slots in one system. For this, you can check if it supports Redundant Array of Independent Disks (RAID) technology. This technology is what allows you to fit in multiple drives in a single storage.
As a business professional, you’ll need a storage device that allows you to access your data and files as quickly as possible. Therefore, you’ll need to choose a rackmount NAS that’s backed by a powerful processor and has enough RAM to ensure you get the speed and performance you need every time.
For larger-scale operations, you’ll need a NAS device whose RAM can accommodate multiple simultaneous connections without affecting the performance. A good rule of thumb to follow is to have at least 1GB of RAM for every 1TB of storage.
Aside from performance and capacity, you also need to ensure that your system is powerful enough to accommodate increased usage without suffering too much downtime. In this case, it should be able to run around the clock with ease and recover from any downtime as quickly as possible.
Ensuring your company’s sensitive data doesn’t fall into the wrong hands is another prime consideration when looking for the best rackmount NAS for your company.
Therefore, you’ll need to select a system that can guarantee that your data will remain safe, even when allowing remote access to your database. In this case, you need to look for a system that offers more advanced encryption options to guarantee your files’ security and your online privacy.
