Are you sure this will be sufficient? I see for example: "HP SAS 15K SFF Hard drives offer sustained performance of 260 MB/s to 175 MB/s (outer to inner diameter)." this would still be too slow. Either you set up a RAID array, or you go for SSD for spool data. > Wolfgang, can you explain please the context between start-stop mode and > the serious > degradation of capacity? Sorry, I don;t have any reliable data here. Modern LTO drives can do "speed matching" (i. e. slow down tape motion for slower incoming data rates), but only within certain limits. Just listen to your drive when running a backup - you can hear easily when it's runnin slower, and when it stops completely. I don't have any documents / specs that allow to estimate the impact on total storage capacity, sorry.
