Why is it a bad idea to use a single 1tb HDD?

Specs: Windows Vista 64 Home Premium, Phenon 2.2ghz 4gb
I was informed that it would be a bad idea to install a single 1tb hard drive and use it to run everything OS and all.
I was told that it would be better to install the OS on a smaller seperate HDD and use the 1tb as storage.

Can someone explain on this?

you were told wrong...it`s ok to use 1 TB HDD...but, you`ll need to create smaller PARTITIONS...one should be for windows, another one for your files...you can partition the hdd while installing an os...I suggest to split the hdd on half...

Probfixer has a good point, but I wouldn't split it in half. Your Operating System partition should be as small as possible, maybe 20 gigs, so if something does go wrong, you can run a scan on the partition in a short amount of time. Any programs you have installed on the same partition as the OS will be erased with a reformat. I think it was Jam who suggested a smaller HDD for the OS and use the terabyte for storage. If you don't make a backup of your machine on a regular basis, and the HDD fails, you'll kick yourself in the butt. Another point for a smaller partiiton of smaller drive is scan time. It takes a lot longer to defrag a large partiton as opposed to a 20 gig. Even a virus scan would take forever. The chioce is yours, as always, but that's my opinion, for what it's worth. Good Luck.

Yep, I was the one that made that recommendation. Have you seen their reliability stats & failure rates? Much higher than "normal" HDDs. Seagate had an extremely bad run on 1TB HDDs early this year with approx 30-40% failure rate.


Even if you were to create a small partition for the OS (which you should do regardless of HDD size), it doesn't change the fact that you're running it from a 1TB HDD. Generally speaking, a single platter HDD is more reliable that a dual platter HDD & a dual platter is more reliable than a triple platter HDD. The more moving parts you have, the more likely that something will fail. And be honest, do you really need 931GB of storage capacity (true size of a 1TB HDD)?

Do what you want, I'm just stating my opinion. If you feel secure with a 1TB HDD, who am I to say differently? Just make sure you have a backup plan in place because if the drive were to fail, you could potentially lose 100's & 100's of GB of data.

BTW, do you know how long it takes to format a 1TB HDD?

"I suggest to split the hdd on half..."

And from a maintenance standpoint, how long would it take to defrag a 500GB, er, 465.5GB partition?

I've been running with 1862.65 GB for a year or two, and I'm starting to run a bit low. I also use by PC as a DVR, so take that as you will.

30-40% failure rate thats put me right off seagate for life.
Might just stick with a 500gb western digital caviar.
I have heard good things from western digital and have had good experience with them before.
The only reason I wanted such drive capacity was because I am building a HTPC soon and thought that I would need lots of storage for HD videos, music ect...

I'd put it all on one drive if I had to. I'd prefer a raid or at least multiple drives. The drive is the slowest part of your system. Two drives can at least split part of the swap file and put OS on one drive and the applications on the other. Slightly faster.

If you have a single drive it makes little sense any more to partition it.

I would recommend using a smaller drive for the OS and programs and keep the larger drive for your media and data files. You can also image your OS drive onto the larger drive if you want.
I have a WD 1TB drive (+3 others from 160-500GB) in an external eSATA enclosure for my video files, so they are only turned on when I need them.
