pros/cons of 7200rpm HD?

pretty much heat and battery life issues otherwise everyone will be running them dirves

 

No problem. Glad I could help and best of luck with your results.

 

Does 7200rpm have a dramatic effect on battery life/consumption?

 

Here you go guys, no more guestimates, no more faux numbers or exaggerated words.










In general most 5400RPM drives higher than 250GB compare directly to the 160-200GB 7200 counter parts. The 5400s are generally quieter, lower power requirements and generates less heat. However the 7200RPMS are the quickest when it comes to access times, whereas the 5400RPMs at the 320GB+ range are the highest when it comes to transfer read write rates.

 

D3X, thank you for posting the charts. However, I am a novice when it comes to reading benchmarks and such, so can you help me interpret the data? Are the higher numbers better or worse? I ask because I have seen some benchmarks where the lower the number, the better. I have seen some where the opposite applied. What's the case with the charts you posted?

 

Well these charts are from Tomshardware, and they often line their results from best to worst top down. There are some exceptions though with the Samsung drive as the data might be interpretted differently* see Write Performance where Samsung is in the middle of the pack due to avg rating, but scores the highest max transfer rate.

 

I'm sorry to bump in here like this without reading all the 16 pages but I've hot a Fujitsu 7200 RPM hard drive on my notebook and I can say that it is considerably louder than a 5400 Hitachi or Seagate (I am talking about the hum of course). I don't now how other 7200 drives are, but I don't advice any of you to buy Fujitsu..

 

I have a Hitachi 7200rpm IDE now, I can only hear it when the room is dead silent, but then it is annoying when you can hear it but other than that its fine Runs pretty cool too.

 

Well, damn already; wish I'd seen these charts two weeks ago! Do you have the link to the article (Tom's HW?) these are from?

I'd swapped one HP for a CTO HP and the one I returned had the WD and the one I kept had the Toshiba in it. A quick "hdparm -t" made it seem that the Toshiba drive was faster, else I'd've swapped drives (I had to pull them both to load my existing SW on the new box and was going to Factory Restore the return anyway).

Ah well, there's a 7200RPM 320GB Hitachi I'm about to go buy (do a lot of SW devel, usually while running a VMWare, so it's worth it to me).

 

Look up tomshardware.com and go to charts then hard drives. The Hitachi 7K200 performs admirably, being at the top or near the top in every test and even consumes a bit less power than every one of the 320GB 5400RPM drives at load.

@ einhander: complete misconception. lower power consumption means less heat and higher battery life, since the 7K200 outperforms the 320GB 5400RPM drives on the list then what you said cannot be true.

 

Does anyone know if Sager NP 2096's HDD brand is? this laptop is sold by Xotic. I want to get 200 GB 7200rpm instead of 320 GB 5400rpm because it may suit my needs....but some brands have worse 7200rpm performance than 5400rpm performance as disk density increases, correct? That is why i ask.

 

Correct. Without knowing the brand it is impossible to say which one is faster.

But both 200GB 7200rpm Seagate and Hitachi are pretty fast, so if I would have to guess I'd put my money on the 200GB/7200rpm being faster in real life. (not in synthetic benchmarks)

 

Thanks for the response.

But has anyone found out what the current HDD brand is for the NP2096 being sold right now by Xotic?

 

Your best chance is to ask that in the Sager forum.

 

Sorry about bumping this up but

How can someone say this? More RPM = More energy needed.

7200 = less battery life.

 

Lol, how can you say that.

Have you heard of new technology? New drive motors? New power management?

 

IaTa makes a good point and you may want to read this review:
http://www.tomshardware.co.uk/notebook-hard-drive,review-31303-16.html

Some 7200rpm drives use less power than 5400rpm drives.

 

My seagate 5400.3 160gb drive used more power than my Hitachi 7K320. My battery life increased by ~10 minutes over the 2 hours of battery life I get. The load readings from cpu rightmark also back that up for me.

So you cant assume a 7200rpm drive uses more power than a 5400rpm one.
Technology is continually advancing, and as of now many 7200rpm drives are more efficient than 5400rpm ones.

K-TRON

 

it's good to know that the 7k320 can now be easily found for $55 at Google shopping

 

RPM won't matter much as long as your system's processing speed is good, in my opinion I think the extra cost for higher RPM is worth it..

 

7200rpm will be a little faster, but will produce more heat and more noise...

hope this helps!

last minute buy, which one:

Fujitsu 250GB HDD 2.5” 5400RPM SATA or Hitachi 200GB HDD 2.5” 7200RPM SATA (No Reserve price)

 

Out of those two I'd get the Hitachi. Unless the Fujitsu is a single platter drive but chances are small.

WD5000BEVT 500GB or 250GB would be a better choice though (performance, noise and power consumption).

 

EDIT:

Western Digital 250GB SATA Laptop Hard Drive WD2500BEVS (5400 RPM) is the one I think you were referring too?

 

No it would have to be WD2500BEV T.

But now that I'm looking at the specs, I'm not sure if it's a one platter drive.

Maybe someone else knows.

 

Ich bought a WD2500BEVT in march 09 and benched it. The Result was very disappointing. Average read was about 50MB/s. That's why I think that this was a 2-platter-drive. If WD already changed that is a good question. If not I'm not sure what the difference between the wd2500bevT and the wd2500bevS is.

 

I think you are right.

Then the Hitachi 5K500.b 250GB is a better alternative.

 

I also had a Hitachi 5K500.B with 500GB. I was very frustrated about the strong vibrations. It felt like a samsung hdd drive . I think vibrations (in a notebook) are even worse than the general running noise. Perhaps I had a bad version. I plan to try the wd2500bevT again. I guess WD will change the number of the platter silently.

 

I think you were unlucky. Most Hitachi 5K500.b don't vibrate at all. The 250GB should vibrate even less.

 

Going from the WD website, the T is for SATA 3Gb/s and the S is for SATA 1.5Gb/s.

On another note, would the Scorpio Black 320GB still be a more responsive drive over a Scorpio Blue 500GB or would the newer density help a lot?

Thanks!

 

It will be impossible to notice the difference without using a stopwatch or benchmark software.

Well maybe during heavy multi tasking it would be noticeable that the WD3200BEKT would be a bit faster. Like here: http://www.tomshardware.com/charts/2009-2.5-mobile-hard-drive-charts/IOMeter-2006.07.27,1133.html

 

Yes Tom's made a typo there. WD3200BEKT is 320GB 7200rpm.

 

Thanks for the link.

I think the second line in each entry just pulls information from another site which is wrong. The first line is correct though - blue, black etc.

I can't really afford a SSD large enough to fit my stuff on so I think I'll go with the WD3200BEKT/BJKT. Unless a 500GB Scorpio Black pops up. =/ hmm

 

Why not do a hybrid SSD+HDD system? Small SSD for os+apps and move the supplied HDD into an optical bay caddy to become a data repository, in spindown standby mode until needed. Optical drive can be hotswapped back in if need to load software or watch a DVD. More info in DIY: Adding SSD and/or HDD storage using an optical bay caddy.

A 30-60GB OCZ Vertex or G.Skill Falcon in the primary HDD bay would give a nice performance AND battery life improvement. Could expand the HDD out to current 250gb-per-platter 500GB 2.5" SATA offerings: 7200.4/5k500.b/WD5000BEVT, depending on how fast you want to stream your data (??) and how much power consumption you're prepared to give it.

 

Besides the FFS, there's no difference.

 

Thanks for the suggestion. I'm using a HP Pavilion tx2500z. I've looked into it and it seems like the optical drive has to be sacrificed as the circuit board is reused for the caddy.
http://newmodeus.com/shop/index.php?main_page=product_info&products_id=223
Plus it might not be so affordable after shipping it halfway around the world.
What might be interesting is if there's a plain sata connector on the motherboard, but I'm not prepared to explore that option... yet.

 

hmm, still haven't found a HDD for $30-$50 USD for my barebones, any suggestions? minimum 200gb

 

The newmodeus configuration table tells us it's a 12.7mm SATA optical drive connector. Dilemma here is the that attached green board to be transplanted. Unless that green board can be *stuck* down onto the systemboard such that you simply slide the optical drive/optical drive caddy into it, as is the case for many other systems. Anyway, you *might* be able to get a 12.7mm SATA ended caddy if ask one of the ebay vendors to make you one from two parts. Consider detail in article DIY: Adding SSD and/or HDD storage using an optical bay caddy
. If you get a second green board as shown and attach it to the optical bay caddy, then can hotswap as well.

 

Well I've heard the BJKT makes no clicking sounds and is more silent than the BEKT. I have the latter and it clicks and sounds like it has an internal fan because is very audible the spindles spinning.

 

Well there have been three people that reported clicking BEKTs and two people had non clicking BJKTs and then people started assuming that this would be the case for all BEKTs and BJKTs.

This is not true. I had a BEKT that did not click and so did many others.

It's like when you see two pretty women from the UK you start assuming that they're all pretty

 

theoratically, the faster rotating element on the hard drive (7200rpm vs 5400rpm) should produce more heat and more noise.
But again, this is just according to the laws of physics.. the 7200rpm hard drive can still be quiter and cooler if quality first class materials and workmanship are associated with the hard drive.

 

Hi nando4, thanks for all the information!
I think I just need another article that will convince me that it is worthwhile spending three times the price of a Scorpio Black 320GB to get something like a 60GB OCZ Vertex SSD.
I doubt that any amount of discipline will allow me to prune all my installed applications to 30GB.

It's just that I've always thought of it as something that I'll do when it's cheaper.

On the BEKT vs BJKT front, I think that there's a whole lot more BEKTs floating around would make a difference to the reports heard.

 

I know this thread was started 3 years ago when it was still relevant, but if you still, for some arcane reason, want to upgrade an HDD but not to an SSD, I say go this route: The 10000-RPM Western Digital VelociRaptor.

http://techreport.com/articles.x/14583

At $300 it's still cheaper than most SSDs, half the price of an SSD of similar volume, and performs better than nearly any 5400 or 7200 RPM drive. And, unlike most 10000-RPM drives, it is both 2.5" (fitting most notebook applications) and SATA interface, as opposed to the more common SAS or SCSI interfaces. Server quality drive with notebook form factor and reasonable price? I think it may be a good option for some.

 

I think you should do more research on the topic. The Velociraptor, while in a 2.5" form factor, will not work in any current (stock) notebook. It requires a 12V line and is far too thick for starters. Plus the last reply in this thread was 4 months ago...

 

Good point. I guess I skipped over that while reading that review.

 

i agree with RogueMonk if that means anything,,,
i recently switched from a 320gb scorpio in my latop to a SSD and havent noticed any changes regarding battery or heat...

 

What's the fastest 500GB 7200RPM HDD?

 

hitachi 7k500

 

How long will it be before we see 1TB 7200rpm hard drives for laptops?
I'm looking to buy one now, but can't find any. Maybe I'm looking in the wrong places??

 

It will take a while. At least until 2011. Unless your notebook accepts 12.5mm drives.

For standard height 9.5mm drives:
The largest 5400rpm drive is 750GB, made by WD.
The largest 7200rpm drive is 640GB, made by Samsung but not available yet afaik.
The largest and fastest available 7200rpm drive is 500GB, made by Hitachi.
