Hitachi Deskstar 7K1000.C 1TB

Looking at getting a couple of 1tb drive for a windows home server that i'm building out of a spare computer that i have.

These drive are on sale right now($75cdn) for the next few days and my googlefu is failing me as i cannot find any review on them or any posts.

Anyone have any experience with these drives?
 
I don't know if it's the exact model, but I have 3 in raid 5 and they are great. Faster then the seagates I had before. Been a few years so far.

My comment would be, why not get the 2Tb version? The price is roughly the same on a $$/megabyte basis (well, a little bit more, which is more than offset by electricity costs), and the drive will likely have a longer useful life in a media server before you need to pull it and replace it with something larger.

I'm personally very happy with my 2Tb Hitachis:

I have a couple 1 TB Hitachis, though i believe mine are the "B" version IIRC.

Also have a couple 2 TB Hitachis

So far had good luck with that brand.
 
thanks for the responses. looks like I will be getting them. I have not had much personal experience with Hitachi other than the laptop drives system makers use.

the reason that i'm opting for 2 1tb drives is primarily for folder duplication on whs, plus if i need to add more drives, the motherboard that i'm using as 6 sata ports on it so not a big issue for that
 
Frys has the 2TB home versions on sale for $139 now.

However, if you were just doing a desktop home system then that would be OK, but be warned about the MTBF. These drives come in two versions : (1) Home & (2) Enterprise. The Enterprise variants (Uktrastar A7K series) have an error rate that is 10X less & has more rigorous tolerance specifications. If you intend to employ these drives in a 24/7 environment, then you need to consider using the Enterprise variant. The lesser mom & pop sold variants assume something like an 8 hr/day useage (ie, not continuous) & the MTBF is unrated.

I never had issues running consumer grade drives in a server environment. My home server has been running for years, it's only been turned off during long power outages (rare) or if it had to be physically moved, or if I had to do any electrical work on the same circuit. So it maybe gets turned off about 5 times a year for about an hour max.

I think the "enterprise" grade thing is just a selling gimick, to some extent. They overmarkup the prices, big companies want nothing but the best, so they pay for it but in reality they are maybe 10% better.

And yeah if you can get the 2TB's for under 300 bucks, then I would go for those instead. That should give you about 3.6ish TB of space if you do a raid 5. (a 2TB drive is actually 2 trillion bytes, not 2 Tera bytes, same goes with any size drive) My current raid is 1.8TB. I have 4 more drive bays I can use so eventually think I'll make a raid 10 with 2TB drives, once they go down in price more.

Just examining that Hitachi spec sheet, it seems that there's really no difference in the drives whatsoever, *but*, if a larger user of drives, ie: Google, were to buy the cheaper ones, and wear them out prematurely, buying the "Desktop" ones would be a reason for them to deny warranty coverage because of over-usage.

The idea that a drive can be manufactured specifically for an 'enterprise' environment, and the same drive can be manufactured for a 'home' environment, with much tighter restrictions, is preposterous.

As for the 1 in 10^14 or 1 in 10^15 bits, 10^14 would imply one bit error every 6.25 times the drive is totally overwritten on a 2Tb drive, which means that, in SMART, these failed reads would show up many times on a drive that has been in service for 2-3 years. This quite simply isn't happening in any major way. Personally, I'm left to believe that the Ultrastar versus Deskstar thing is little other than a marketing strategy.
