Yeah, I found that out when I installed my two 7K80 SATA-II's. It took a call to Hitachi for me, though, but they were extremely helpful!

There is no review of Hitachi t7k250 drive anywhere in sight in the storage section of AT. there is a maxline review where they compare it to a whole bunch of drives including a 5 year old ibm 75gxp. i have no idea what you go by but you need to compare apples to apples. and don't be sorry. in fact anandtech while being a terrific site when it comes to silicon has nothing on places like storagereview and cdrlabs when it comes to storage. the hitachi drive we're talking about here is the latest generation drive that has only been announced 3-4 months ago. if you want somewhat of a relevant comparison you can compare the 2 year old Hitachi 7K250 SATA I without NCQ to the MaxLine III right HERE

You will see that even though MaxLine beats the Hitachi in quite a few benches the old Hitachi keeps up and even manages to edge out the Maxtor in 7 benchmarks one of which iincludes average service time. Now, with this new Hitachi drive that has NCQ it is quite possible that it will beat Maxline or at least be just as good at a fraction of the price. Also, please show me any credible place that actually demonstrates how a increase in cache alone affects the drive's performance in any meaningful way.

the old hitachi 7k250 is great.


there is a guy on ebay selling them for $90 shipped. i was able to get 2 used ones with 2 years warranty left for 170 shipped. 500 gb of storage baby!

well talking about bang for the buck, I got 500GB of WD and get pay 60$

Here's a little something to whet your appetite:

2 x T7K250 in RAID0 on an NF4 Ultra

Will be interesting to see how this stands up in IOMeter!

EDIT: How do you post images in this forum? :disgust:

Lowlight- You going to redue the review since you chanced it to 3gb/s?

Wonder how it effects loadtimes, etc with that. :)

Going to do a full review of these babies in RAID1, RAID0, and Single Drive mode. Comparing to either a pair of 'Cuda 7200.7's or MaxLine III (same as DiamondMax 10).

Don't worry, I won't do this... ;)

For some reason.. I can't get the feature tool to boot up on my dfi nf4 ultra-d....it goes to "Loading PC-DOS" or something like that..and just is stuck there... anyone have any idea what's room? i'm using the bootable CD by the way.. Thanks.

WHAT?!?!? Tisk tisk...

I read all of everyones comments here and i believe the Maxtor 10 owns the hitachi, in more ways than one. I read reviews too also but its late and ill try to find the review again comparing and testing the drives more extensively than those mere tests on that review.

I believe Maxtor had two versions of the harddrive also, the first generation ones they sent to review websites had issues, and was slower for some reason.

The 2nd and now is what you would get if you buy it, is faster than the hitachi. But seriously, thats a bad review, it doesnt compare and test it as extensively as many other reviews i've seen before i got my maxtor 300 giger. Not only that, they obviously had the one ones sent to them by maxtor themselves. If you buy one and test it, it owns the hitachi.

http://www.tomshardware.com/storage/20050418/diamondmax_10-05.html

Thats the only review i can find now but look at it, owns the hitachi in write/read mbs and heat. That one doesnt have the noise test but i still acnt find the review but it owns in that too. The only thing hitachi owns a little in is random access time, but maxtor dint make a hard drive made for servers, where I/Os and random access time matters more. This hard drive will probably load a game faster than a raptor in the future. Keep reading them reviews, try transfering (reading and writing) a 500 meg file, this thing OWNS a 74 giger raptor at that. Can anyone say fast game loading?

To the guy that asks wut does even more buffer do? Are you kidding me? Do i really need to answer that? READ more reviews. Search for diamondmax 10 reviews on google. Dont search for hitachi cuz you wont find much reviews for that, proabably because it isnt that great of a hard drive. But if you look on websites that review the diamondmax 10 then you will find it compares the 7k250 like the link above. Ill admit the diamondmax 10 is more expensive. More space + more performance.

I had the exact same problem on a test system (can't remember what it was, but I think it was an Intel 945P mobo)

I had to use the floppy to get it to work.

seeing as the hitachi 7k250 (and this is a 2 year old drive btw, with no ncq etc) still beats the maxtor by over a second in access time, i wouldnt call that the maxtor owning the hitachi.

i have a 7k250. i ditched my raptor 36 gb for it. its a cheaper, a nd quieter drive. i got mine for $85 shipped on ebay used. works great. and even if i had to pay $120 i still think its a better deal, seeing as it has faster access times which really help in real world performance.

Dude, there are two version of the 7k250. The one review is udpated, SATA II, 300, and not the 85 dollar used SATA-150 your talking about. Two year old hard drive my ass. As for real world performance, the maxtor does own, you need faster read/write mbs, not faster access times. Unless you can tell the difference in 1.2 ms.


Not to mention, SATA II standard was just introduced last year. You obviously have an old generation one. SATA II standard came out in July of 04?, Intel held a press conference or something. But anyways NForce 4 Ultra (which supports SATA II, and only thing different from regular NF4) came out october 04. Whats this about hard drive being 2 years old.

uh in that case you are still wrong.

the new 7k250 is called the t7k250. from what i've seen in reviews its more or less the same drive. just the interface is different, but ncq doesnt exactly make much of a difference.

based on your logic, a 36gb raptor is quite a bit slower than most 7200 rpm drives, since its transfer rate is not nearly as fast.

the 7k250 and t7k250 in average read service time (not seek time, but full read service) are actually nearly 3-4 ms faster than the maxtor diamondmax 10 and its twin the maxline iii (same drive different warranty and usage ratings though, but this is the best i could do for a review link).

http://www.storagereview.com/articles/200406/200406207B300S0_2.html (average read service time)

http://www20.tomshardware.com/storage/20040820/hitachi-maxtor-10.html

check the i/o per second on the hitachi drives over the maxtors.


i/os are important when there are lots of small reads. these usually correspond to lots of read and write access, such as writing to a page file, the biggest bottle neck on most systems.

anyways, i dont really care particularly what you beleive, but most people who know better know its more about access time than transfer rate. ask around anands.

the maxline iii / diamond max 10 would not be my choice for drive . i'd get the t7k250 (which is what this thread is about, an improved 7k250) any day especially at this price if iwanted ncq, sata2 etc, and a faster quieter drive. hands down its better.

Your obviously wronge. "Thus, the performance figures from our already-published MaXLine III review represent the performance one may expect from a 300 GB DM10 equipped with a 16-megabyte buffer."

"EXPECT" is not what is. The maxtor diamondmax 10 is not exactly the same im sure.

Your giving a link to tomshardware, the same website i gave link to the maxtor.

"the only differences are the validation process and a longer warranty period." About the maxtor 10, not sure what that means, but looking at the link i gave, it does have a maxtor maxline III 250 giger on it in the charts. Looks like the max 10 is faster. So there is a difference.

the maxtor 10 is faster in interface bandwidth and slower in access time.


that is what you've been saying, and i agree. part of that interace bandwidth is because of the extra cache for one thing. and regardless of if its faster at interface bandwidth, the access time is more important.

it is just liek ram.

would you rather have higher bandwidth ram or better latency?

usually people say better latency, which is why people say ddr2 is not that great since it is higher bandwidth but worse latency. everything in computers is about latency, thats is why there are l1 caches on your cpu, or caches on your computer, or on die memory controllers etc. latency is the most important thing 90% of the time.

hmmm, that's extremely unfortunate for the dude that got defective ones.. mine arrived well packed and and been kicking ass so far. i was thinking of getting more today but i see they're OOS already. btw, i forgot to mention that the drive feels extremely solid and well optimized for desktop. it's the fastest 7200 rpm i've had so far in any capacity. (i have 2 x wd1600jb, older hitachi 7k250 and 180GXP, seagate barracuda 7200.8, samsung 1614c and used to own a multitude of scsi 7200rpm'ers)

I stand corrected since i did not know most perfer better latency.

Sounds like an awesome drive. The question now is whether or not I get another DM10 250GB for the sake of having two of the same drive, or the Hitachi instead. I don't think I can go wrong with either drive, but why pay $40 more for the DM10 if it doesn't add any real performance? Perhaps I should sell the DM10 and get two new Hitachi's instead? Oie, the decisions we must make.

Anyone know if ANY PCI (not PCI-X or PCI Express) cards that support SATA-II 300mb/s?

Also - saw this posting after googling.

The new drives like the 80GB HDS728080PLA380 have SATA300 disable from factory.
To take full advantage of the drive's speed you must enable it by using Feature Tool (v1.97) otherwise the drive is working as SATA150

DO NOT enable SATA300 if your controller doesn't support it!

Check out the burst rate after re-configuring the drives:

the pci bus is saturated by sata1, there is no point in getting a sata2 card in pci format.

the absolute fastest drives (i think that new sata2 samsung) is 72 mbytes per second throughput at the outer edge.


pci bus on a normal pci slot is 133 mbytes per second. sata 2 is 300 megabytes per second and sata 1 is 150 . sata1 is already more bandwidth than the pci bus, and this is assumign that you sata card has the entire bus to itself (its a shared bus, usually 3 devices per slot, correct me if i'm wrong)

Lowlight - You should at least put a disclaimer in your present article letting readers know about the messup with the not enabling the 3 gb/s on it for review. Might confuse people reading that, then read your new one when you put it up. ;)

I just got 3 of these when they were at $127.
I am putting them on an LSI Mega RAID controller for RAID 5.
I am considering adding a 4th, but no rush since the LSI offers online expansion.
In this case I am interested more in safety then speed.
When a 250GB or larger drive dies this could hurt, but with RAID 5 I am running at
1/2 the speed, but all the data if a drive dies until I can get it replaced.
