Both are 'bout same price (Seagate costs just a hair more, despite being 250 gigs short), some stuff I read about both: complains about the Hitachi being a bit on the noisy side and about the NCQ thingy for Seagate, some say it's great, others not so much.
Of the 2 go with the Seagate. A third better choice is the Samsung Spinpoint F3. It is faster, silent and very reliable as well as being super cheap. It comes in 500GB or 1 TB models.
Is this the one? Samsung 1 TB SATA-II 7200RPM 32MB PMR Spinpoint F3? What does PMR stand for? And I read a few comments on this one and a lot of people complain that it isn't silent, not necesarily very loud, but not silent. (and it's actually a tad more expensive than the seagate)
I have used dozens. They are as silent as any mechanical drive I have ever used of any brand.
Here's a quote from a review on this Samsung: "Under heavy load (such as our IOmeter random write test) the drive was clearly audible over the sizeable background hum of our labs" (http://www.bit-tech.net/hardware/storage/2009/10/06/sam...) Plus, every second user comment I read (local forum), said it's noisy.
I don't live in the US, so prices on newegg are irrelevant in my case. They are more expensive here in Romania, and if I were considering spending a bit more on the Samsung, wouldn't it make more sense to just get a Seagate 1TB SATA-II 7200 rpm 32MB Barracuda 7200.12?
Ok. So here's another idea.
Spinpoint F3 1 TB vs Barracuda 7200.12 1TB. Acording to the review the Spinpoint is a bit faster but the Barracuda makes less noise. And what about NCQ? Does the Spinpoint support it (I know the Barracuda does)? Does it make any difference at all?
