I'm shopping for a server that will allow my coworkers to use QGIS through a terminal server. We have 2 Tb of orthophotos in tif, twf, ecw and shapefiles format. They tell me that actually when they work with orthophotos it can be sluggish. The way they describe it, the loading time of the orthophotos seems to be the culprit. They work with the orthophotos stored on an external HDD through an USB 2.0 connection.I consider buying extra big SSD drives to store the orthophotos on them to assure the best performance, however an IT consultant tells me he thinks it would be relevant and the performance gain compared to using HDDs for those file's storage would not be significant (we will however put the OS and the main files on SSD drives). Has anyone experienced working with orthoimages on SSD drives, and is the performance gain significant compared to working with orthoimages on a HDD ?
