Which one is better? Better performance or less platters?

I am looking for a new application HDD from my computer. I have a 500 GB Seagate 7200.10 now but I'm looking to go to 1TB. This is strictly a Windows, applications, and games drive. No music, movies, etc...

Possible upgrades I'm looking at are Seagate 7200.12 1TB or WD Caviar Black WD1001FALS. I know the WD has better performance for applications which is what it will be used for but the Seagate has less platters (2 500 GB vs 3 333 GB). Less platters mean less heat, less moving parts, less chance of failure, etc.

Price-wise the WD is only $10 more on newegg which doesn't matter to me.

  1. All HDDs will be slow for this. If you can't afford the applications to be stored on SSD instead, this is your only option. But i wouldn't worry about performance; it will be low anyway. The only real performance difference is between HDD and SSD; especially regarding application launch, booting; i.e. system disk related tasks.

    When you do buy a HDD; get the 500GB-per-platter disks. The 333GB are older generation HDDs. It wouldn't matter anything in random I/O performance however.
  3. Oh I know SSD's are the performance kings. But they don't currently offer enough space for a reasonable price for me. I do mostly PC gaming so I need a ton of space for games. And seeing as a 500 GB SSD costs over a $1000 (half the price of my computer when I built it 2 years ago), it's really not smart for me. Maybe my next computer in a year I will split up Windows and games on seperate drives. This will let me put Windows on a smallish SSD. But I'm not about to change for this computer. Thanks for the advice though.
  4. Alright, just wanted to make sure you don't concentrate too much on performance when looking for an HDD. For your purpose, any HDD will be slow. Since you have no alternative; look at price and future upgrade plans.

    If you need a 500GB system disk, SSDs are still very expensive yes. My own system disks are 8GB large thus a 40GB SSD would fit 5 workstations. In essence, i share my ssd across all workstations.

    In your case you have a lot of games. A nice alternative would be to get a small 40GB Intel SSD for the system and use a big 1TB HDD for your games.
