Hitachi Brings 400GB to Desktops with the Deskstar 7K400

Pure Hard Disk Performance
To measure "pure" hard disk performance, we took a real world benchmark - in this case, the entire Winstone 2004 suite - and used Intel's IPEAK utility to capture a trace file of all of the IO operations that take place during a single run of Business Winstone 2004 and MCC Winstone 2004. We then use IPEAK to play back the trace, much like a timedemo, on each of the hard drives, which gives us a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation.In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance.
Keep in mind that these performance scores are best only for comparing pure hard disk performance, and in no way do they reflect the actual real world performance impact of these hard drives.
For descriptions of what the Business and Multimedia Content Creation Winstone 2004 tests consist of, reference those benchmark pages.
With the exception of the latest generation MaXLine III, the Deskstar 7K400 offers about a 17% performance advantage over the next fastest Western Digital and Maxtor drives.
The 3% performance difference between the Serial and Parallel ATA versions of the 7K400 is basically negligible.
Under the content creation IPEAK test, the 7K400 is able to match the performance of the original 36GB Raptor; this time, offering about a 6% performance advantage over the next fastest 7200RPM IDE drive.
With performance advantages of just 17% and 6% in the two IPEAK tests, we see that the 7K400 is fast enough to hang with the present-day contenders, but you shouldn't expect anything earth shattering in the way of performance.

This is great but unless it geting into the 50cents per gig range it won't really make sence. I could just get 4 200gbs for the same price and raid themgimpsoft - Saturday, July 10, 2004 - link
if you have space for 4 drives on your casei say go with mulitple 160GB hard drive or 149GB true GB
149 * 4 = 596GB almost 600GB
$93 * 4 = $372
for $93each why pay $450 for 320GB
samsung Hard Drives on newegg
mulitple drives is much better then one
C/windows E:/storage X:/storage D:/storage
so you uncompress a file from C to C will take longer & won't be able to open anythign else until uncompress is done
from E to X or from C to X you could surf the web have an dixv open with small slow down & have it finish faster then having to be done in one drive

Nice to see capacities increasing. Seems like for a while there hasn't been much in the way of capacity increases... just some speed increases with the Raptor and SATA.A friend of mine heard about the drive too and asked why anyone would need 400 GB of storage space if they weren't doing anything illegal like pirating software or media. My answer to him was, programs (especially games) will only get larger. And with no worries about storage limits, you could rip your entire CD collection in a lossless format and keep it on your hard drive for listening and making MP3's to put on a portable device, etc. Then there's video... with more people building HTPC's, a 400 GB drive would be a nice addition to a HTPC for recording TV shows in HD... copying your DVD's to the drive for quicker viewing and not having to mess with the discs all the time.
I think storage space is lagging behind a little bit... I have a 36 GB Raptor and an 80 GB drive and I don't find myself running out of storage space, however, I do find myself deleting things thinking "I don't really need this, I'll just get rid of it and free up some space." I remember back in the mid 90's I think, I bought a 12 GB Quantum drive, when high capacity mainstream drives were 6-8 GB... the Quantum was a HUGE drive at the time, but pretty slow. Where are the HUGE but slow drives today? I think it would be acceptable to use a 5400 RPM drive in a HTPC if it could offer 50-100% more storage space thana 7200 RPM drive, AND be more quiet and cooler. Or just for people who archive home movies or something... an 800 GB drive would be great for them... speed wouldn't matter all that much because a 5400 RPM drive is perfectly capable of streaming DVD quality video and audio.
Anyway... as I said... it's nice to see storage capacity increasing, not just speed.

"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."Anand, do you have any specific information on future roadmaps by the manufactures. I would be interested to see how Western Digital will respond.

Nice article. I can appreciate the difficulties in trying to bench and review HDDs, but so far i feel you have done a good job, and i am very much enjoying reading these HDD reviews.Only thing, it may have been a good idea to talk a bit about some of the technical features of the Hitachi 7k400 - such as those 2 sensors on the underside of the HDD that help ensure much greater spindle head accuracy through system vibrations than currently seen in other HDDs. The name of the technology evades me now, but it sounds really cool.
In any case, great review - the Seagate Barracuda 7200.8 looks like being an awesome HDD, so i do hope that there'll be a rview on that sometime soon :)

Nice review. The recorded hard disk sound is a very good addition. You guys just need to edit the first 1-2 and last 1-2 seconds to remove those weird sounds and it will be perfect.You can actually hear how silent is a barracuda and how loud is a Maxtor or a WD SE.
It's good to see my one year old Western Digital SE near the top of the performance charts. It shows how hard it is to improve hard disk performances. Kudos to Hitachi for a great hard drive.
Thanks ;)
