It's been quite some time since we reviewed a 4-bay NAS, but we still had the Thecus N4200 on hand. Since we are now testing with Crucial RealSSD C300 256GB drives, a retest was in order. These are the world's fastest SSDs at the moment and allow very fast formats in NAS servers. When using mechanical drives some of the formats could take up to 30 hours and the SSDs cut that time down to around 10 minutes.
Testing and giving results of the Seagate BlackArmor was a little tricky since it comes with two drives and most of the other NAS servers we test are diskless. For today we chose to show the results for the BlackArmor as it shipped, with two Seagate Barracuda LP drives in RAID 1. We also moved that arrangement over to RAID 0 to see how it performed in that configuration. To keep with our apples to apples numbers we then installed four Crucial RealSSD C300 256GB drives in the BlackArmor 420 and ran tests in RAID 0 and RAID 5.
Most users will either run their BlackArmor in RAID 1 with two drives or migrate over to a three or four drive RAID 5 array. RAID 5 is the ultimate array for the home or small office environment, but larger businesses will want to run RAID 6 or higher and the BlackArmor 400 Series simply doesn't offer anything higher than RAID 5.
The difference between RAID 5 and RAID 6 is that RAID 5 will allow a single drive to fail and still retain your data, while RAID 6 will allow for up to two drives to fail while still retaining your data.
The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. Designed to emulate the behavior of an actual application, NASPT uses a set of real world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation and more provide a broad range of different application behaviors.
