It certainly seems to be the cheapest 250GB single platter.zzombi wrote:Great thread, given that single platter F1s or 320GB WDs are yet to come this drive looks interesting. Is this HD250HJ really the currrent holy grail of the silent pc enthusiast, with low noise/temps and yet good performance?
Could someone post some benchmark numbers? Even better a hdtach or hdtune graph.
And if it is 7200rpm instead how can it get such amazing wattage? Either way looks uncanny.
There are hdtune hdtach results of it online. One I saw had a 13.58MB/s minimum speed, so something was amiss. Maximum was 102.5MB/s so it actually looks to be faster than 7200rpm. The similar 250GB single platter P7K500 is slightly faster at real apps (6279 PCMark05 Diskmarks compared to 6168 for the Samsung) but slower on the synthetics.
Thanks guys. This is almost as good as the F1s, so it's very likely a 7200rpm drive.
The Hitachi P7K500 250GB is 7200rpm and equally impressive in consumption (3.3W for PATA), so I guess these hdds use newish very efficient motors?! The Samsung wins at noise though, at least on paper. It looks there's no need to rush about SSDs
PS and the hd250hj has no hutil issues that I heard off too

80? How about less than 35E? What worries me are reliability reports of the Spinpoint F1 series, albeit more platters. Beware of the 251 and 252kj models, apparently not s250 series, ie 250GB platters.

"The F1 series puts 333G on one platter"
The 750GB F1 has 250GB platters.
BTW, I can buy HD200HJ for a good price. Does anyone know whether it's a full platter or a short stroker? Could find no hdtach/hdtune graph on this one, so please, anyone
The tell tale sign of the good disks is the weight: only 463g!

"Even if they did they would still use a full sized physical platter but the inside tracks would not be used."
As a result the stroke of the heads is shortened. That's what I mean by short stroked.
A short radius disk sounds interesting for noise benefits, but I haven't heard of it in 3.5" 7200rpm form.
A hdtune graph would shed light on HD200HJ being just a 200GB density platter, as the max read speed would be decreased vs HD250HJ.

Just like chip fabs, they have older factories that make the top end 166GB per platter drives (obviously now old), and that factory will then get a re-fit and new machinery and will then start making the new 500GB per platter models (obviously not yet).
Basically its cheaper to re-fit a factory and get it to make the same drives until they are obsolete and then move it on to making new stuff rather than re-fit them regularly.
Samsungs new line will last a lot longer than the competition as they have a head start in capacity, so it will take longer before they are obsolete.
I also believe that when Samsung created the F1 line they decided to use the old 250GB platters and just add a few models to their lineup, which in theory means that the T166 range wont last that much longer as the new range includes the best selling 500GB model.

Looks like HD200HJ has lower density platters than HD250HJ. The medium transfer rate is only 73MB/s.
Even if they used the same platters physically wouldn't it be easiest to factory format them with lower density, using a different firmware? And I don't think we can reformat them at 250 easily, for obvious reasons.
Funny is that international online prices for the 2 models are about the same, it's just that local stores make the 250 more expensive and harder to get.
There are even 160GB HJs, probably the same situation as with the castrated CPUs, just to fill more market niches.
As for the head start, WD announced 320GB platters too, the rest have 250GB, so I guess they kinda missed it with the huge launch delay.

I believe the one-platter 332G F1 has been sold (and sold out for the first run) and also reviewed in Europe. Perhaps I should have written that *some* F1s have ~333G platters?zzombi wrote:"The F1 series puts 333G on one platter"
The 750GB F1 has 250GB platters.
edit: The very first feature is "up to 334G per platter" (official Samsung F1 site/data).
I see what, you're saying. I agree that the lower the density the better the reliability for a given state of tech, but even the 750GB F1s, with lower densities, have some problems, perhaps a bit over say Seagate or Hitachi drives, which seem to be regarded as very reliable (Seagate even has 5 years warranty).
That doesn't quite fit with manufacturers' claims: unrecoverable read error rate gone from 1 sector in 1E14 to 1E15, from S250 to F1 series. Why if it's plain vanilla? Aren't both perpendicular recording?

new single platter Samsung
HD252HJ
It's an F1 family member, ie 333GB/platter.
Higher consumption (5.32W vs 3.2W), same noise, 16MB cache, quicker (short stroke- 12ms access time), naturally faster (100MB/s average).
Any first hand experiences? Especially in comparison with other single platters, or the popular WD 640GB biplate. And is it free of hdutil errors?

"In your opinion is it better a Samsung 250GB..."
Yes. It is faster (larger platters, 333 vs 250), less noise and heat (only one platter), less cost.
However this is only how things SHOULD be, I have not tried them. I am a little worried by the multi platter F1s not so good reliability record.
Basically equal rpm and platter capacity drives should offer similar performance, but things like noise/vibration, consumption/temperature and the most important reliability should be checked. A notable exception is Seagate, which has some problems with multithreading, because of inneficient firmware logic.
And don't forget, HD250 and HD252 are different. WD is selling a 320GB monoplatter too, unfortunately it is somewhat slowed down from firmware to make ppl buy more expensive multiplatters instead.

My two-platter P7K500 is noticeably quieter than my HD250HJ. The Samsung sounds more like the WD6400AAKS. The single platter P7K500 is probably much quieter than the HD250HJ (but also much slower?)zzombi wrote:Great thread, given that single platter F1s or 320GB WDs are yet to come this drive looks interesting.

Did you mount them suspended by elastic?
Do you have the 640AAKS too, and isn't HD250HJ a bit more silent?
The specs show the Samsung to be quieter than the Hitachi, though. There's also some variability to individual samples.
