I have definitely considered more than once about using tape storage, and I think one day I will buckle under this pressure. I have huge storage needs, but I digress. This post is about trying to get faster access. Check this out -- I found this command that can help me quantify how slow things are going:

sudo hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   17184 MB in  1.99 seconds = 8617.86 MB/sec
 Timing buffered disk reads: 198 MB in  3.02 seconds =  65.65 MB/sec


..Seems darn slow... I do think I may do something like my OS drive is cheap and small like 64GB to 128GB SSD and my file storage will be on a slower hard disk. Right now I actually just have a 8TB RAID1 as my main backup. I was looking at Bcache or caching using a separate flash storage but it seems a bit fiddly for me. I'm just techy enough to learn this stuff but not techie enough to be living in the command line 24/7.

Thanks for your thoughtful response.
