We've noticed a trend taking place in the network attached storage (NAS) market. With CPU performance on the rise, NAS manufacturers have taken enterprise features from larger servers and incorporated them into lower priced NAS products. The result is more features for less money when it comes time to update your company's storage solutions.
Over the last two years, we've seen a rise in features such as cloud access to data from a NAS, 10GbE connectivity, improved iSCSI support, and now RAID 50 and RAID 60 support.
From the Thecus press release:
RAID 50 combines the advantages of RAID 5 and RAID 0, to surpass the performance of both of these lower RAID levels. RAID 50 brings improved read speeds, significantly faster write speeds, greatly improved fault tolerance, reduced access time in random access operations, and greater storage capacity. RAID 60 combines the best of RAID 6 and RAID 0, to improve further on these advances.
Compared to RAID 10, RAID 50 and 60 require much less overhead storage capacity. Therefore, they cut system costs, power usage, and physical space demands, while still retaining the ability to survive multiple drive failures that would wipe out lesser RAID systems. The greater fault tolerance of RAID 50 and 60 also means little or no loss of performance while a failed drive is swapped out and restored.
Supported models with the new RAID levels are: N6850, N8900, N12000 Pro, and N16000 Pro. All four of these models also support 10GbE via an add-in card. The maximum capacity for the N6850 is 24TB, but the larger units support Thecus's new expansion units, and scale to 2.5 petabytes.
Today we're running Thecus's N8900 unit in RAID 50 and RAID 60 to see how well the new RAID level works on a unit we have in the office.
