[QUOTE="Lehmden, post: 1143357, member: 109222"] Hi. Did you ever try to copy six (pretty big) files from one drive to another at the same time? If you copy one file it may have 100Mbyte/s (as example, could be more or less, depending on drive type, but 100MB/s is a good average value) , if you copy two files each has a maximum speed of 30 MB/s, if you copy three there is far less than 10MB/s and when there are four, the average speed goes down to some hundred KB/s. Not to mention the clearing of cache, what leads all other copy operations to stall completely for a certain time...And the copy operation only did read, not write... Timeshifting is comparable to copy a file to a different folder on the same physical drive. And here the speed is much slower than to copy from one HDD to a different HDD, so for 6 x timeshift at the same time you can expect a "speed" of a few kb/s only... I often do copying of big files and I always avoid copying two files at the same time, as it's slow as hell compared to copy them one after another. [/QUOTE]
