My question is should I Raid the two 1TB into 2 partitions for Scratch & Data a
not sure if you mean data as in BU ? but I would not do the same physical HD for both data and scratch ? using one for scratch the rest for BU is fine
short stroke it or partition it into two make the top one about 100 gigs the bottom 900 is then for your BU (Back Up)
this will give you a faster scratch for PS work not effect your BU at all
a lot of options here is one with the stuff you have
SSD boot (off the extra SATA ? in the optical bay)
I would say depending on your storage needs ? which would be good to know
🙂
1) wd 2TB black
2) wd 2Tb black raid 1 setup of two 2TB WD blacks for data that way if a HDD dies you dont go down and can keep working and not loose time !
also try not to let these get over %60 full ever ! they will slow down some say %50
🙂 thats even better if you can
3) 1 TB WD black two partitions 100 gig scratch and 900 gig data BU from your raid 1 setup or your main working files
4) stock drive partition two 100 gig top make a clone of your boot drive ! this way if your boot dies you can quickly switch and be working again a program like CCC on schedule will do this the extra can be a time machine or second BU set?
if you think your files are going to be more than 900 gigs of stuff ? remember try not to get your main working drive to full !
you could do is with slots 3 & 4 take those extra two 900 partitions left over and raid 0 them for time machine or BU
but if you do this you will have to put one more external of some kinds on their to have a solid BU not relying on raid 0
🙂
that external could be a FW800 or esata setup ? lots of options here
wife uses both FW and eSATA
our reason for one set of FW BU is we can drop this on any mac if we need to and get files out to clients ! and not need to worry about eSATA
we can even run this off a laptop if we have to !
this of course does not include off site BU
🙂
for files under 1 gig Iyou could just point your scratch at your BU drive and you should be fine
a quick side note since your files wont go above 1 gig you could put the scratch on the same as your files ? but you might take a hit in writing files or reading files from disk ?
when and if you hit the scratch doing other things you wont notice much of a performance hit then !
my wife does our design side and she opens and works on about 30-150 PS documents a day in the range of 80MB to 300MB the ones that take longer are of course ones with more text !
