5200 RPM vs 7200 RPM

[akocli]

I have to decide whether to buy a 5200 rpm HDD or a 7200 HDD.
I already have a small SSD, so I'm not worried with loading times for OS or games.

My main focus is in storing my files.
Are 5200 rpm HDD are more reliable, or the reliability is so insignificance that it won't really matter?

Don't consider a 7200 rpm , waste of money.

There is no decision, a 7200 rpm hard drive will kick the arse out of a 5200 rpm drive (these ARE for laptops).
No reliability comparisons; 5200 rpm drives are generally just cheapo 'Pants'.

None of that is true. Traditionally 5,400 RPM drives have demonstrated greater reliability. The parts are under less stress because they do the work slower, they use less power usually, and they generate less heat. 7,200 RPM drives have classically been chosen over 5,400 RPM drives only for faster performance.

Today, technology has advanced quite a bit to the point that the difference in how fast the drives wear out is negligible. Therefore the 7,200 RPM drive is the better choice because it does have a small performance advantage over the 5,400 RPM drive, but reliability is not higher than 5,400 RPM drives.

Instead, the specific drives you are considering should be investigated as different models may have inherent design flaws that make them worse, or may have shown to perform exceedingly well and reliable. You can't judge universally based on RPM.

This is an important aspect to consider too. If they are about the same price, 7,200 RPM is better because of the small performance advantage.

If the 7,200 RPM costs more, which is usually the case, it isn't worth it. The performance advantage isn't anything spectacular.

Usually the difference in price is negligible , so the 7200 rpm is the best option in most purchasing situations , although some markets are limited.

I get what you are saying Dude, but to equalize performance on a 'giveaway' box, you need 3 gig of ram minimum if you use a laptop hard drive or a non sata hard drive.(reclaimed spares).
Is it 'odd'? Yup.
You can run benches till the cows come home but a sata 2 7200rpm drive and 2 gig of ram will perform similarly in a surfing box to what I describe,at least as far as the normal user is happy with it.
Using a lappy drive needs a root round the draws for that odd gig of ram.

I'm not sure what you mean by a "giveaway" box, but none of what you are saying is making sense to me.

First, you keep calling the 5,400 RPM drives laptop hard drives. There are plenty of 3.5" desktop hard drives that run at 5,400 RPM. Here is an example of one:

But you can find dozens of them.

Second, RAM usage isn't going to change between if you have 2 GB of RAM or 3 GB of RAM. If you have less RAM, the system may have to access files more frequently, but it isn't going to be noticeably slower between the two drives. Web browsing doesn't really use the storage device, so that really doesn't change anything. It would be noticeably slower than you have less RAM in most cases, but that is a RAM issue.

I would have to say I disagree with you on the ram usage front, I suspect it is a long time since you ran windows with 2 or 3 gig, and possibly never with your current O/S.
Just in windows with nothing else running ram usage will increase depending on what is available.

I've ran Windows 7 and Windows 8 with 2, 4, 8, and 16 GB of RAM, and yes Windows makes greater use of the paging system when you have more RAM available. But, this isn't a question about how much RAM the user needs to have, it is about what hard drive. If he only has 2 GB of RAM then he is going to experience considerable lag regardless because of heavy use of the page file. The transfer speed on a 7,200 RPM hard drive isn't going to be high enough to negate the negative impact of using the page file and will seem little better than a 5,400 RPM drive in that scenario.

akocli - Your original question is about hard disk drive reliability. The answer is there are some older 5200 rpm hard disk drives that have proven to be quite reliable. Unfortunately, those older 5200 rpm models have been replaced by 7,200 rpm and 10,000 rpm hard drives that have a SATA 3 6Gb/s interface and a larger cache.

Hitachi "Coolspin" drives run at 5400rpm and are the most durable and longest-lasting drives available. My experience with these drives is very good and I don't notice any performance issues compared to 7200rpm drives, though I'm not a demanding user in that regard. Western Digital has acquired Hitachi, however, and I'm not sure how their products might change as a result. Hopefully they will use Coolspin in their other drive lines but this sort of information is not easy to obtain.
