Seems a good price so I've ordered one. I have free postage which helps. :thumbsup:
#2
I love free next day postage from Scan, pity you have to spend £20+VAT to get it though.
#3
yep, this will work in a ps3, as its 9.5mm high.
#4
Is this drive the same anyone?

And if not which one is better? Thanks:thumbsup:

I think that some of the "high capacity" 2.5" drives use extra platters to gain the same amount of storage which also makes them slightly thicker (don't quote me though).

Fewer platters typically means lower noise, lower power consumption and lighter.
A 3 platter drive with the same capacity would also generally have a lower data density so the transfer rate is higher for a 2 platter design.
And probably most importantly 3 platters designs are too thick to fit in most laptops or a PS3.

cheers guys :)

Do you have a link to a data sheet to confirm that? I couldn’t find much info on this drive and nothing at Samsung.

For that size of 9.5mm in a 2.5" drive it would have to be two platters or under.

Having three platters would require a 12mm drive.

I have this drive and it is great.

Another bonus to get the newer drives is they run much cooler too. This drive for example will run much cooler than a drive made in 2007 so you could upgrade your PS3/Laptop.

I checked before I ordered that they are 9.5mm but I couldn’t find a data sheet for this model which is what I mistakenly assumed you had found.

They were on Today Only for £57.56 when I ordered but it was about to end so I posted at the full price afterwards.
#14
Voted hot and ordered. Been wanting to upgrade my ps3 for a while now.
#15
Im not sure if im willing to part with £60. Is it worth upgrading my PS3 from 120 gb? I wana put alot of TV and Films onto it.

Its really up to you I suppose, but the 120GB drive doesn't have to sit in a drawer. You can just buy a 2.5" caddy/enclosure and use the 120GB HDD as a backup drive (roughly 111GB)

I upgraded from 80GB to 320GB when I bought the PlayTV adapter

How can 120GB be 111GB?

Maybe you mean GiB?

I know exactly what he means as I inaccurately only use the term GB although I appreciate the difference.
I buy a 1TB drive and format it and then call it a 935GB drive. I don’t think many people bother to use GiB. I see a bit like a tax that you can’t avoid so I ignore it.

Marketing folk have 1GB defined as 1000000000 bytes, instead of the amount of 1073741824 bytes (i.e., what Windows sees and defines as 1GB -- 2^30).

So 120GB / 1.073741824 = 111.7GB :)

Additionally, this causes a 1TB drive to actually be 931GB according to Windows.



However!


Excellent price for a slimmer 2.5" drive. Heat from me :)

Nope, 120GB = 111.7 GiB :thumbsup:

It is only windows which counts 1024 bytes per megabyte, which is just lazy :-D:whistling:

Well, I refer to the International System of Units; you refer to the International Electrotechnical Commission.

The latter is technically correct, but nobody uses it in the real world! :lol: Without splitting hairs, I think it is safe to say either/or are accepted :thumbsup:

Nobody uses it in the real world? it depends what operating system you are using.. my install of linux uses it for one example.

Anyways, u made yer point, go and play DOTT :)

Linux? Rinse your mouth out! :lol:

I said real world!

All jokes aside, yeah, I know what you're saying - but it's one of those things, like how Sellotape, Velcro and Post-it are all trademarks that have become generic terms!

yes it can work.
#27
This looks like a great deal H&R
#28
Doesn't the PS3 use a different file system meaning you'll get far less than the 640GB on the drive? Will the drive format automatically upon insertion?
#29

yes it can work.

i understand its a good one for ps3....but is there something better for the macbook?
(it works really slow) maybe something might speed it up abit

seems like a very good deal:-D

Received mine this morning and I had the HM641JI not the HM640JI which is the same drive as the Amazon deal.
#33
Would it not be better to just have a usb powered external hard drive?
Rather than mess around (Even though its supposdly easy to swap PS3 drives) opening your ps3 hd bit and then buying a caddy for your old drive etc
#34
good for ps3 thanks
#35
Does someone knows good aluminum enclosure which will work with this HDD 640GB?
Most of them works only with 500GB HDD (at least that info is on most of them)

Thanks,

If the enclosure comes with a Y-splitter, you should be fine. It's not the capacity that is the issue, rather the ability of the USB port supplying power. USB 2 is 5V and 500mA.

I have a drive that is not meant to work on a single USB connector and it's great - but not all drives will be the same. Check before you buy :) Did anyone find the datasheet for this drive to confirm power requirements? Having only two platters is promising for sure.

That's almost certainly going to require a Y-splitter to spin up with 100mA, but the regular read/write would be fine once it gets going...

... not that it helps!

You might be lucky and find that it spins up okay regardless on a single USB cable, but then again, you might not.

Those HDD are used in Samsung's ext drives and they use only one cable, so I hope it will work.
Thanks for your help.

Are you 100% positive the cable isn't a split cable?
