Read that, it is the topic directly below the one you posted.

You are the first person i have ever heard say that a 7200rpm drive will use more power and cause more heat than a 7200rpm drive. I understand the logic behind what your saying but you are not taking a lot of other things into consideration. The new models are engineered more power efficiently. Some 7200's will use more power, some will use less. Either way though, the HDD does not run for long amount of times in the ps3, just during installs and loads. And when your installing or loading the rest of your ps3 is at rest so to speak. It is only using only a small fraction  of the cpu power and none of the vga's power. When your playing a game and stressing your cpu and vga, your HDD is at rest in idle.

The data transfer will be limited to what the ps3 is programed to. If the ps3 is not capable of receiving data and sending data at 3gig/sec then it wont.

You mean, a 7200 over 5400 right?  And if that is so, WOW, where have you been?  We talked about the 7200 drives, it's power requirements and the more heat they generate raising the overall ambient temp of the PS3.  7200 RPM drives require more 12V power for the spindle motor, and they do generate more heat.   This is why, IF you modded an XB1, you needed to have it cool better, so the alternate dashboards, and XBMC, began coming out with FAN override values, so you can have a default speed better than 20%, to 100%, to accommodate the extra heat in the unit.  You had to hard wire the fan at 12V for 100% high all the time beforehand.

For Towelie006: The SATA controller in the PS3 is SATA-1 which is 150, not 300, so putting in a 300 drive won't make too much of a difference (tests were done, are at the end of this post).  THE 7200 rpm would be naturally faster than the 5400, due to the read and write interleave.  Interleave is, how many rotations occur before each read/write is performed.  Like, a 3:1 ratio means, data as read every three complete rotations of the spindle, the larger the ratio, the slower the drive reads and writes.  All drives optimally would be at 1:1.  Remember the old 5.25" two cabled MFM and RLL drives, where you could CHANGE the interleave to make then faster, but never at 1:1.  STock, they were like 4:1 to 7:1, and best you could get was 3 or 2:1.  If you tried 1:1 and it did not work, you got like a 10:1 response from it... 

So, if a 5400 and 7200 RPM drive had an interleave of 2:1, or whatever, the 7200 drive will still read and write faster because the RPMS are faster at the same interleave.  The only way a 7200 drive would NOT be faster, is if the interleave was 3:1 on a 7200, then it would be the same R/W as a 5400.

In order to use a 7200 RPM drive in a PS3, it should conform to the power usage that is indicated on the stock 5400 drive itself, the new "Green" drives would be an example of what may work.  IF you can find a 2.5" SATA "Green" drive, at 7200RPM, then it should be ok all the way around.   Just look at the power consumption ratio on the stock drive, and compare it with the replacement. 

For Example:
Seagate:  5V 0.57A / 12V 0.22A (2.64 watts)
Western D: 5V 0.80A / 12V 0.35A (4.2 Watts)

Those are two 5400 Stock Xbox drives as an example, the ONLY two used in the Xbox1, they came with NOTHING else but one of those two drives.  Also, the Seagate it a 10GB, and the WD is an 8GB.

Now, a WD 7200 RPM drive in a modded XBox: 5V 0.65A / 12V 0.90A
Notice the 12V Amps is more than twice the 5400s.

TO convert those 12V AMPS (I) to WATTS (P) with ohms law (P= E x I so P=10.8watts).  The watts is what translates into HEAT.  Not sure on how to convert watts to heat, never bothered with that, but it is like 6-7 degrees higher than the lower watt drives. 

Naturally, 2.5" drive power consumption is going to be LOWER than the 3.5" drives, thus lower heatt and amps, but I was using those as an example, to show you the jump in power consumption on the 12V side with the 7200 RPM drives.

PS3 - THE TESTS:
Temperature testing against the two hard drives yielded a minimal difference; no overheating will occur with a 7200 rpm drive, ostensibly. I read the HDD itself was 3 degrees hotter with a 7200 RPM drive. 

Installing demos after downloading off the PSN had an average of ten seconds shaved off due to the higher rpm drive, except that Tony Hawk demo, with destroyed over forty seconds of install time.

Loading games generally yielded minimal results, unless you consider 2 seconds of load time a big deal.

IT is safe as far as some people are concerned...

quote:"there's really no reason not to buy a speedier hard drive for your PS3....that is, unless you're concerned about voiding the warranty."

will changing the HDD void your warranty...?i thought i see somewhere stated that changing hdd will not void warranty....pls advice me and correct me if i'm wrong on this....

WrAth2110 from http://boardsus.playstation.com/playsta … ].......it DOES void the warrenty. Infact when I called to get exchange my first PS3 because it wasent workign right they made sure that I didnt replace the HDD and that the sticker was still in tact. It does void the warrenty, Sony's at least.

Sony included the instructions on how to replace the HDD in case someone who doesn't care about warranty wants to upgrade AND  for people who's HDD fail after warranty runs out. If you break a seal or sticker or anything like that it is a dead give away you just voided your warranty. Unless the manual actually says "this will not void your warranty" it probably will. I am pretty sure it says in the manual that opening the ps3 in any way will void your warranty.

EDIT: that guy misquoted Sony, as long as you have your original HDD your warranty is good, but if your ps3 breaks you have to put the original back in before you send it to sony. Still i am not sure, a lot of people on that forum said they called sony. Some say sony told them it voids warranty some said sony told them it does not.

It should NOT void the warranty though, IMO, because they show you how to do it...  Oh well, still, once you format a new drive in your PS3, the original one won't work if you plug it back in.  So, if teh PS3 is dead, then you can't format it back, HOWEVER, I don't see Sony not honoring the warranty unless they can specifically tell that the 7200 RPM drive caused the problem.  They probably record the temps and rpms somewhere, XBOX does.  There are probably the same sensors as PC motherboards have.

Umm, TOWLIE, I posted:

It tells you the speed difference, so you ask again after I posted it? 

They are not going on LOAD times yet, neither console has been hacked to allow RETAIL disc games to be installed to the HDD, so they should not be doing any load time tests.   There was little evidence they they were doing that with the ORIGINAL Xbox, because the game would run on DVD, but not off the HDD, so there had to be an issue.   Even with XB1, simply putting a UDMA66 cable in there increased STOCK drive load times from both the HDD and DVD (no error retrans). 

It will not effect games running from the OPTICAL drive, only content cached to the drive.

They will only INSTALL as fast as the SOURCE sends to the HDD in any case, so if your internet connection is slow, then nope, no difference at all, you should know the physics of all this stuff.

READING will be increased for sure, but not by much according to the tests.

Pay attention to what people post, so you won't have to ask again dude...
