Which is Better? 32mb vs 64mb

[Thefirstbuild]

I'm building a budget PC and I noticed 2 types of HDD Drives with the same "Capacity" but their price is different by $10. Check out the link below and tell me which I should buy.

That's a cache size thing, when there's a choice like that I always opt for larger cache.

The HDD Cache, 64 is better.

it's essentially 'Ram' for your HDD.

32 MB vs 64 MB cache makes very little difference.

The Hitachi drive (HDE721010SLA330) uses 3 platters of about 330-400 GB each.
The Seagate drive (ST1000DM003) uses a single 1 TB platter.
The WD drive (WD10EZEX) uses a single 1 TB platter.

That will have a much bigger impact on speeds than the cache. The Hitachi drive maxes out at about 90 MB/s, while the Seagate and WD drives max out around 160 MB/s.

To be honest though, I'd save the $10 and put it towards a 120GB SSD for your OS (maybe also programs depending on what you want to do with it). They're down to about $50 now, and will be roughly 4x faster than the Seagate and WD drives at sequential transfers, a hundred times faster at small file transfers. You're already buying outside the peak of the capacity per dollar curve by getting a 1 TB drive (best value is at 3-4 TB at the moment). I wouldn't compound that error by wasting more money on a "faster" 1 TB drive.

these specs, when you compare raw performance, you will probably not notice it. if you want speed, ssd is the way to go.

typical setup, ssd for os and some apps/games (due to limited space) then a few terabyte for other things

Absolutely agree with this, even on budget builds SSD's are getting very affordable. Even if all you put on it is the OS the performance difference is dramatic. Once you go SSD you'll never go back. Only thing I use mechanical drives for now is backups and large data files/music/movies etc... Stuff that doesn't typically need very fast load times anyway.

you guys are lucky, my first ssd some years ago, 80gb was like $200 locally (cheaper if it was in the us, but not here). imagine the price-gb ratio now than then.
but, that 80gb, still have it. still plenty fast (now have 2 ssd btw), and it wasn't even the fastest back then (but was the most reliable, it's intel)
so if you think it's not worth it now because it's expensive, imagine back then that was sata2 era. but it's worth it
