Hitachi equips the E7K1000 with a full 32MB

As opposed to a partial 32MB? If it was a 16MB or 64MB cache, you'd still write "a full 16/64MB...".

It's a meaningless term.

There's an updated 7K1000 non-enterprise version which I believe uses the same platters called the 7K1000.B that is a little more price-competitive with other 1TB drives. *whoops, it's mentioned on page 1 :p and yeah it has 16MB cache. Any chance that will be tested to see the impact of cache size?

Also, FYI, Hiatchi's feature tool can be used on drives other than Hitachi as well. I've used it to change AAM on WD drives, Seagate drives don't allow adjustment though.

Here we see AAM pay off to the tune of two-and-a-half decibels

54.2 - 52.7 = 1.5 dB.

/me hopes for a review of the new 500GB/platter Seagate soon (and why not the 2TB WD)

Does TR ever use technical replicates for tests (multiple hard drives, processors, etc. of the same make)? It seems like when the numbers are this close, the comparison might benefit from fewer types of hard drives and more statistical power, although I know that everyone wants something different from a hardware comparison. TR's hardware reviews are much more helpful than every other site I've seen, but I was wondering whether this site or another offers this type of review or if it generally is not done because of price constraints. Is there any other way to get an idea of how capable different companies are at keeping quality consistent across certain product lines? Any help is appreciated.

Specs say HDT and HDE721075SLxxx are 4-head, 2-disk. Meaning the 750G models would be 375G per platter, and probably faster streaming. (Also notice that noise/power figures are identical for 500G and 750G models.)

Those 3-platters aren't glass are they?

I feel kinda jaded after seeing SSD benchmarks. Mechanical hard drives are definitely still relevant, though.

Interresting! Both quiet and efficient with real good performance. A bit pricey though I'd say.
I'd like to see a review of Samsung's EcoGreen F1 1TB drive. The F1 is good but would need some less noise and power consuption to fit in an HTPC.

Why hasn't Hitachi changed the Deskstar name since IBM? I could never again buy a "DeathStar" due to the two bad ones I have. A 120GB and an 80GB drive. I RMA'ed to IBM but they just re-formatted and returned. When the drives get hot they just quit working.

I aprove of this 5 year warranty. Now, if it would only apply to the cheaper non enterprise drives...
