160gb in my MBP but it is connected to a 750gb + 600gb + 500gb + 160gb external HD's so in total I have a 2.17tb which is still not enough for me...need that new MacPro to come out soon so I can put 4tb + my externals in it.
RAID 0 is used for absolute performance but has no tolerance for data corruption or disk failure. If you're looking for data security, you should be mirroring your set-up in RAID 1. I don't think RAID 5 or 6 would really be practical for personal use though as they require at least 3-4 HDs.
got it all to hold datasets for my thesis. Now I'm sporting 1TB of free space.
That's really bad. If you have so much free space then you should be using RAID 1 minimum. Or sell everything and rebuy with RAID 5 in mind, you still get the read performance of RAID 0 and the decrease in write performance is neglible in most usage scenarios.
4x 500gb RAID 5 - 1.37TB storage on my ReadyNAS
1x 300gb usb
1x 320gb usb
2x 100gb 2.5" usb
100gb internal hdd on laptop.
amazing when I think back to how well I ran on a single 1.2gb hdd just 10 years ago. And how happy I was when I dropped $100 to get a 5.4gb hdd at CompUSA. And now you get nearly 100x that amount of storage for the same price at Fry's nowadays.
