How to choose rack-mounted hard drive enclosures

• Compatibility with Desired RAID Levels:

  Before making a purchase, it is important to determine which RAID level is desired for storage. Some enclosures offer the option to configure different RAID levels, while others are limited to one specific RAID level. Enclosures giving the choice among several RAID options tend to be more expensive than those offering a single RAID setup. Therefore, it would be wisest to first identify which RAID option is preferred and then narrow down enclosure choices based on that need.

• Intended Usage:

  It's crucial to consider how data will be used before buying an enclosure. In some cases, enclosures are used just for backup, so keeping costs low might be best. If data needs to be accessed rapidly and frequently, spending more for higher performance could be worthwhile. Enclosures designed for moderate usage may suffice if neither of those situations applies. It's important to match enclosure features and costs to actual usage needs.

• Budget:

  The more devices an enclosure supports, the more it will likely cost. When selecting an enclosure, evaluate how many disk drives are needed now, but also consider future expansion needs as data storage requirements grow. It's usually more affordable to have a larger capacity enclosure than to buy multiple smaller ones separately. Having a higher capacity enclosure can also minimize costs in other areas, such as cooling systems and RAID devices.

• Other Features:

  There are a few additional enclosure features worth taking the time to consider. Verify that an enclosure provides sufficient cooling to regulate temperatures properly. Investigate how easy and fast it is to integrate an enclosure with existing systems. Be certain that users are aware of and know how to utilize any new features an enclosure may offer. Reassess the importance of any other extras like power supplies or network connectivity, and make sure best practices are followed throughout the evaluation process.
