HD153UI vs HD154UI

[Tesselator]

Can someone tell me what the differences between these two drives are?

EcoGreen F2 1.5 TB HD154UI (http://www.samsung.com/global/business/hdd/productmodel.do?group=72&type=61&subtype=78&model_cd=441&ppmi=1170)

EcoGreen F2 1.5 TB HD153UI (http://www.samsung.com/global/business/hdd/productmodel.do?group=72&type=61&subtype=78&model_cd=444&ppmi=1170)

Anyone?

Download the data sheet.

Data sheet seems to indicate the 153 only has 16MB cache, 154 has 32. I am guessing that's the difference, and the website is just wrong as it seems to indicate even the 153 has 32mb.

Ah OK, that seems right. Thanks man.

I'm also wondering if one is 3 x 500 GB platters and the other is the older 4 x 38X GB platter configuration. But it's kinda hard to say. the HD154UI if for sure 3x500 GB but I dunno what the HD153UI is. Hmm.. Oh well. I already bought 4 of the HD154UI ones earlier today while at the shop in Honda City. So now it's just academic wonderment I guess. :)

I didn't look at the .pdf data sheets yet, so I didn't catch the error on the cache capacity on the website.

But the platter density is what I was wondering as well. Do you know the platter count of the HD153UI? That would give it away. :p
