Top 12 Best Budget 2-Bay and 4-Bay Network Attached Storage Enclosures The effective space is halved but you get peace of mind. Data is striped across two disks as in RAID-0 for performance and mirrored as in RAID-1 with the second pair. There is another RAID common among 4 bay NAS enclosures, RAID-10 requiring a minimum of 4 disks. CON: Write operation will be slow, effective space is less than the total space as some storage on every drive is used to store parity information.PRO: Good performance and Good Redundancy, data is striped and parity information is distributed over three of more drives.Only half the storage space (1 disk) is available to user. CON: Normal performance as there are no striping or parity information to write.PRO: Blocks are mirrored with every data written twice for redundancy.CON: No redundancy or fault tolerance, no parity information.

PRO: Best performance as data is split and written simultaneously over two disks.In RAID-5, part of the storage space is used to carry parity information required to rebuild a failed disks. In RAID-1 and RAID-5, should one of the disks fail, you can swap it out with new hard drive and rebuild that data across the RAID again.

Since you are considering a NAS enclosure, you would know some of these, the handy setup wizard will take you through deciding which best suits your need. The 4 bay NAS supports RAID-5 offering a balance between performance and security with part of each disk used for parity while data is written simultaneously over striped volume.

Or, if you need security, it supports RAID-1, mirrored volume where the same data is written twice, one on each drive. The dual bay option gives better performance with RAID-0, striped volume where data is split and written simultaneously across two or more disks. It combines multiple physical disks into a single logical unit. NAS offers RAID (Redundant Array of Independent Disks) technology for performance and/or redundancy. While there are cheaper single bay enclosures such as the Synology DS112j, DS 114, DS115j and DS115, ZyXEL NSA310S and QNAP TS-112P, TS-120 and TS-131, we focus primarily on 2 and 4 bay NAS. Apart from ZyXEL NSA310S, the prices of these single bay NAS are not very different compared to its’ 2 bay siblings. NAS are also a low cost option for businesses looking to back up their data either locally or remotely.
