Thecus N5550 5-Bay NAS Review

Last of all is a test based around a photo album. When a photo album is viewed on screen, only the images that you see are loaded from the drive and so when you scroll through the album, the new images have to be fetched and read. The album here contains 169 photos with varying file sizes based on the size, quality and detail in the image. Reading the files in a photo album puts an unusual read load upon the drive as the metadata is read, a thumbnail constructed and finally the image viewed.

RAID arrays typically work better with larger amounts of read data and not smaller files and reads so as expected the test results are very similar across the range.
