Hitachi Brings 400GB to Desktops with the Deskstar 7K400

Final Words
There's not much to say about the performance of Hitachi's Deskstar 7K400 other than it's competitive with anything else out there today. What the 7K400 does offer today is the largest single drive capacity for a desktop hard drive, at 400GB.Hitachi is the first to the 400GB mark and currently, they are the only one to offer the drive size. So, if that's a requirement of yours, then there's no options to consider other than the 7K400. If this is a purchase that you must make today, there's nothing to complain about when it comes to the 7K400.
If you can wait on that hard drive upgrade, however, much newer technology is coming next quarter. With platter densities finally surpassing the 100GB mark, 16MB buffers to accent and with NCQ becoming mainstream, the 400GB offerings that should hit the streets later this year will hopefully offer more than just massive storage capacities, but maybe even a new level of performance.

Hummm yourself #15, the Seagates have fluid bearings as well. Its not just these two drives...all the results are highly suspect. The values are far too close together, both between drives and for the same drive between idle and load.The review numbers are wrong.

I'd also be happy to sacrifice some performace for extra space (and also increased reliability as well if it has a lower rpm) on my largest drive. The Quantum Bigfoot drive (5 1/4" 3600rpm) I bought in the late 90's was slower than most others but offered considerably more GB/$ than faster drives of its day, and was ideal for my needs then. Its still working fine to this day in my second box.When you're considering archival drives of many hundreds of gigs capacity, economy and reliability are far more important than speed.

#6's idea of wanting larger storage (not necessarily speed) also interests me. I guess if 133GB platters are available Q3 and 5-platter drives are engineerable now, then 5x133 = 665GB drives should be (theoretically?) possible from Q3. I'm looking forward to the race to the first 1TB drive in 2005.jiulemoigt - Monday, July 12, 2004 - link
hummm #14 look up fluid mechinics isolations then turn on a grinder, and weither his number are right the fluid ball bearings should be quiter than the graphite drives. My spelling is due to the time of night. I wouldn't have said anything but I have six raptors (the newer ones don't know how loud the old ones are) in an array and you have to get pretty close to hear them.masher - Sunday, July 11, 2004 - link
While I appreciate the addition of the sound ratings, I have a hard time believing them. The 10K Raptor quieter under load than a Seagate 7200? No way. The quietest disk of the bunch at idle is the 5 platter Hitachi? And the Maxtor only half a db difference between idle and load?Sorry, you did something wrong to get these numbers. All the values are far too close together for one...maybe your SPL meter is filtering out part of the spectrum, or reading some background noise.

#12- I assume you didn't read the earlier review on RAID0 and the conclusion that there is negligible performance advantage to using RAID0 on a desktop PC. Although the article only considered two 74GB Raptors in RAID0, the conclusion is equally applicable to other drives, more drives, or other controllers.StorageReview.com noticed the article and all the comments from readers because they faced exactly the same criticism when they found RAID0 was basically worthless, and have posted a large editorial on their front page making it quite clear RAID0 is not worth using. I suggest you read AT's earlier atricle as well as those on SR.

I know you spend a lot of time making these and i greatly appretiate them but i would like a comparrison of RAID setups. I hear claims all the time about certin drives in RAID are faster then a 72GB Rapter or some drives are faster in RAID then others. I am just curious if you could do a set up of the top 5 individual drives and set them up in RAID.i am just throwing some ideas out there....
thanx

Article looks great! You can't beat a 400 gb hard drive! (Well, at least not for a few more days or so!) A quick question however... the PATA version of the hard drive loads UT2004 almost a second quicker than the SATA version. Is this an actual difference in the two drives, or is it just a fluke in the test that doesn't really have a technical basis to explain it? I see the SATA version beats out the PATA version in every other test, but being a gamer this definately raises my curiosity!Again, as always, great article!

What to do with 400GB hard drives? Aside from pr0n, serious photographers that work in digital (either straight from the camera, or scanned from film) can testify that once you get a .PSD with a few adjustment layers, some layer masks, etc., it might well reach the 500MB range or more (or if you got a drum scan, it might start out at 400-500MB before all the layer masks are added!). And most people don't shoot just a few images per month; draw your own conclusions.
