Number of drives
NAS enclosures are available with different numbers of bays – some will of course already have built-in drives whereas others will be diskless bays. At Weable.co.za you are able to find an enclosure with anything from a single bay all the way up to 24 bays with 4 or 8 bay solutions being very popular.
Hot swappable disks
This is a very useful, possibly essential, feature found in many NAS solutions. In the event of a hot swappable disk failing it can be replaced without having to power off the NAS. In the meantime though the NAS will still be able to function without the failed disk.
The vast majority of NAS enclosures use wired Gigabit Ethernet connectivity. This is the fastest and most reliable solution especially as most enclosures will have multiple Gigabit ports that can be linked to provide redundancy in case of one failing. Similarly, look out for multiple Ethernet ports as they can also be linked to increase data transfer speed.
Wireless NAS are much less common and don’t provide the reliable streaming and uploading of wired models.
The convenience of remote access shouldn’t be under estimated. Many NAS devices have this capability and it allows data to be retrieved by anyone with network access no matter where they are. For example an executive in a meeting can pull up information when required or a colleague working at home can access and then save reports to the NAS.
Every NAS device should come with pre-installed software that automatically schedules and carries out back up. On the next page of our NAS buyers guide we will look at choosing the best solution for you.
