Quick Take
Our limited experiences to date with the Hitachi Deskstar 7K1000 have been terrific and beyond expectations. The overall performance of this drive has been phenomenal and is close enough to the WD1500ADFD Raptor drive that we consider it a worthy adversary. The Raptors are still the drives to own for benchmarking but this drive is a better overall performance value. In fact, based upon subjective testing we could seriously consider tossing this drive into the same performance sector as the WD Raptor when utilized in the typical gaming or enthusiast level machine where this drive will likely find a home.
We found the overall write performance and sustained transfer rates to be excellent and class leading in several of our test results to date. The drive even has the best overall thermal and acoustic characteristics of the high performance 7200rpm drives and absolutely blows away the Raptors in this respect. Of course, the 7K1000 does not have to contend with 10,000 rpm spindle speeds and firmware that is generally designed to extract the greatest amount of performance from the drive. However, considering the drive has a five platter design we think Hitachi has done a wonderful job in controlling thermals.
Hitachi's implementation of their Automatic Acoustic Management technology on the 7K1000 does not hinder performance in a noticeable manner and offers a significant advantage for those needing a spacious drive in a silent system. We cannot wait to test the CinemaStar version of this drive that will be designed with DVR operations in mind but for now our HTPC test bed has found a new drive. As stated in the article, we believe leaving AAM and NCQ turned on provides the best performance experience with this drive. While there may be a very slight performance advantage in certain benchmarks with AAM off (NCQ also), we feel like the benefits of having a near silent 1TB drive in our system is well worth the price of losing a few benchmark points.
The Deskstar 7K1000 is not without faults. We did find in our Nero Recode tests and to some degree in our Winstone tests that the drive does not perform as well as expected in handling large block sizes of data in sequential order. The Achilles heel of the Seagate 750GB drive was its inability to handle large files in non-sequential order. Hitachi has overcome this for this most part with a large 32 MB cache and from all apparent indications firmware that is tuned with operational balance in mind or even favoring non-sequential read/writes. A luxury it can afford due to its cache size and areal density advantages over the other drives in our test group.
Overall, we think Hitachi's Deskstar 7K1000 is the best 7200rpm drive we have tested to date. This is quite the accomplishment considering this is Hitachi's first 3.5-inch form factor drive that utilizes perpendicular recording technology. We still have significant testing left to complete on this drive that includes our full IPEAK and Application test suite with AAM and NCQ turned off or on along with RAID testing but we do not expect to find any surprises at this time. With an expected retail price of $399 or $0.40 per-Gigabyte this makes the 7K1000 a true value considering its size and performance. For these reasons, we highly recommend the purchase of this drive if you are currently looking for a high-capacity drive with performance to match.
We would like to thank Dell once again for providing our test samples and encourage you to visit StudioDell or take a look at the systems currently shipping with this impressive drive.

"Considering the importance of data integrity in today's systems"...? You mean like, in yesterday's (or perhaps tomorrow's) systems, data corruption was considered normal or acceptable?Gary Key - Tuesday, March 20, 2007 - link
It was not meant to infer that data integrity was not or will not be important.Spoelie - Tuesday, March 20, 2007 - link
No, but if you lost a hard drive before, the amount of data that would be gone is nothing compared to the amount of data you lose with current hard drives. It's always a BAD thing to lose data, but it's BAD² to lose data². So it's important² to keep data² safe ;pJustin Case - Wednesday, March 21, 2007 - link
"Data integrity" and "drive failure" are two different things. Most data integrity issues are related to bad sectors and corrupted data (and that is why Hitachi chose to go with more platters and lower areal density - less chance of localized data corruption, but actually a slightly higher chance of "catastrophic" drive failure - namely a head crash or a dead motor). The article's author got _that_ part right.The problem was what came after it. It was just as important to "keep data safe" last year (or the year before that, etc.) as it is this year, so qualifying it as "in today's systems" makes no sense.

I changed it back to the original text. ;)

Looking at the benchmark charts, one thing that pops into the eye is that your world at AT, as far as HDDs are concerned, seems to revolve around Seagate and WD only.But theres quite a few other manufacturers out there that make good drives (that surpass many of the featured drives in one way or another) - this new Hitachi beast proves it.
Go ahead and test more Samsung, Fujitsu, Hitachi and even Excelstor drives.

ExcelStor drives are refurbished IBM/Hitachi.Gary Key - Tuesday, March 20, 2007 - link
We finally have agreements with Samsung and Hitachi to provide review samples so expect to see reviews of their drives ramp up quickly. We are discussing a review format for SCSI based drives at this time and if we can do it right then expect to see this drive category reviewed later this year. We will also be introducing SSD reviews into our storage mix in the coming weeks. While I am at it, our Actual Application Test Suite will under several changes and be introduced in the 500GB roundup. Thanks for the comments. :)

Hmm. Only vendor I am interested in seeing him added is Samsung. They have quite a market share here in Germany.JarredWalton - Monday, March 19, 2007 - link
My personal take is that for 99% of users, it doesn't really matter which brand you use. Seagate may win a few benchmarks, WD some others, Samsung, etc. some as well. In reality, I don't notice the difference between any of the HDDs I own and use on a regular basis. I have purchased Samsung, WD, Seagate, Hitachi, and Maxtor. Outside of the Raptors being faster in a few specific instances, without running a low level diagnostic I would never notice a difference between the drives. I suppose I'm just not demanding enough of HDDs?
