3.5 inch slim Hard drives ?

emeraldsmines1990 · Jul 8, 2018

I want to ask if modern Slim 3.5 inch hdd exist ? I mean by modern , Fast , 128MB cache , 7200 RPM drives. Capacity 2-3TB ..

I understand That we have upto 12 TB HDD today in standard 3.5 inch , which means they can make slim ones 1/3 height for 3TB using fewer platters .. but I could not find any.

you'd just put a 2.5" in and use a case to convert it to 3.5"

emeraldsmines1990 :

The 3.5" drives are all the same "thickness" for mounting standardization.
1 platter or 4 inside, the box is the same size.

We had slim 3.5 inch HDD in the past. but I cant find modern ones. The mounting holes are the same position just the thickness is different.

Yes. while it is true, some are thinner, the only real solution is what I offered. Unless you want to trawl through hundreds of spec sheets of HDDs

Real solution ? 2.5 inch HDD are not reliable and are very slow compared to modern 3.5 inch ones . unless you get SAS 2.5 drive then you will have to pay 5 times the price per TB plus a SAS controller .

Then you buy an SSD and your worries are over.

ElectrO_90 :

do you know how much 3TB SSD costs ?

Please stop bothering me.

emeraldsmines1990 · Jul 9, 2018

I asked about SLIM 3.5 inch , I did not ask for 2.5 inch nor an SSD so go away. you are not helping you are trolling. you want me to pay Thousands of dollars for 3TB SSD and you call this a solution?

It´s a really simple answer, there are none.

Mobile or slim HDDs 3.5" are dead.

What height do you need your HDD to be?
https://en.wikipedia.org/wiki/List_of_disk_drive_form_factors

You will have to look at the data sheets, which HDD is 19, 25.4 or 26.1mm. 2TB and more should all be 25.4 or 26.1mm

just an example of HDDs heights in relation to capacities:

helpstar :

19mm height is good for me , but it seems they are not making them 2-3TB ... only upto 1TB ..

Thanks for the detailed Wiki site. This is what I call real answer.

You are welcome

Seagate ST4000DM004. 4TB, but only 5400RPM. $96. https://www.newegg.com/Product/Product.aspx?Item=N82E16822179299

Per spec sheet, z-height is 20.2mm: https://www.seagate.com/www-content/datasheets/pdfs/3-5-barracudaDS1900-10-1802GB-en_AU.pdf

You are unlikely to get a 7200RPM drive larger than 1TB in a thin 3.5" form-factor.

I mite end up using intel Optane caching and the 4TB 5400 RPM thin 3.5 inch HDD. Thanks for all replies.
