Thanks alot for your replies I appreciate it but still I got no where if anything I am more puzzled with this RAID thing setup you just told me about I normally use RAID for the server at work I'm a network administrator but never heard of it for a home PC.
please find my comments below.
Hard drive performance is over rated IMO. You won't notice the difference in units with slower read or write times. You need at least 16MB of cache on a drive that size and of course 7200RPM.
okay I am going with the Seagate ST31000333AS. (hopefully it's a good choice)
I have been using Western Digital drives of late.
I also use WD as a default but the market for it in my country is very poor all the ones I found so far are old ones very old models and no 1TB drives. So unfortunately I am going for what's available and newer.
I don't know how you plan on filling a 1TB drive up. Do you realize how big that is? How about this 750GB for $90 with free shipping.
I already have a 500GB secondary SATA II and a primary IDE 80GB's which is used for the OS. I have Windows 7.
so I am considering using the new HDD as the primary 55GB partition and the rest for my backups.
I download a lot of HD movies and TV Shows each file is around 1.1GB on this rate I think I will be needing another 1TB in a few months! :-(
If you really think you can fill up most of a 1TB drive then how will you secure the data? About the only practical method is another hard drive or tape. Why not get two of these instead and either run a RAID 1 array or just simply occasionally sync the drives.
what do you mean here by the backup and secure process what use shall I get if I had another 1TB drive?
RAID 1? as in shadow my first 1TB drive into the second 1TB drive? ummm wouldn't be that a waste of space since it will be a shadowed drive I don't think I can use it to store my files in it either so I'll actually have one 1TB drive with a 1TB backup. correct? what's Array?
You should also consider multiple partitions. Your boot partition should be small enough to be easily backed up. The OS is what changes the most so should be backed up the most frequently. Also, if you restore the OS partition the remaining storage will all still work without a re-install of everything. Look at the link below for more on partitioning.
30GB is plenty for your primary OS partition.
I am assuming you need SATA II drives?
Yes I will be using SATA II drives. And about the OS partitioning I will have it at MOST 60GB since I consume alot of space and Windows7 takes up to 30GB with all the updates (last I remember).
Once again thank you alot for your help OTheHill and appreciate your final comments specially in the RAID section what would it be use for me besides the backup? I have read online that using RAID actually slows down the windows desktop interfaces.
