2.5 inch 3TB or 4TB drives on the horizon?

There are some people here who just don't like Samsung. My own experience with Samsung SSDs is positive. I have a 1TB 840 EVO mSATA which has been in use for 22 months. It might be suffering from a bit of the read speed slowdown problem but I have nothing to compare it with and have no alternative (except for the Samsung 850 EVO) to get 1TB in the mSATA format.

By far the worst SSD that I have encountered was the Sandisk U100 which had abysmal write performance and could cause the computer to temporarily freeze.

Fair enough!

How about the 4tb seagate 2.5 drive:
http://www.amazon.com/Seagate-Portable-External-Storage-STDR4000100/dp/B00ZTRXFBA

 

@Kyle it's over 9.5mm high... btw, did anyone take it apart? Is it SATA or native USB?

 

If the bare drive is the unit discussed here then it's 15mm thick with 5 platters.

The length of the casing (116.9mm) is sufficient to include space for a SATA-USB adapter but this isn't conclusive evidence that the bare drive inside has the SATA interface.

Seagate launches an 2TB 2.5" 9.6mm external hdd, so how many mm is the hdd inside? 7mm?? 3TB or 4TB 9.5mm possible???

I remember reading a customer review somewhere in which someone opened this 4TB case only to find two 2.5" 9.5mm 2TB 5400RPM HDDs (Samsung M9T) in a RAID like configuration.

According to this it is indeed a 2.5" 7mm 2TB 5400RPM HDD with SMR technology, as opposed to PMR technology in the previous 2.5" 9.5mm 2TB 5400RPM HDD (Samsung M9T).

Last year I bought a similar drive from Seagate, 4TB portable it was actually setup as 2 HDDs in RAID 0 to achieve the 4TB, the thing died within 1 week making me lose all my data. I personally will never touch any drive that has SEAGATE on it

 

4TB abnormal height drive and 2x2TB RAID 0 in single enclosure coexist; the former is obviously better choice, while using the latter without Y-cable is like playing with fire. I prefer Seagate because for the last 5 years they were always the first to become available in highest capacity and normal (9.5mm) size, and usually come with native SATA interface, at least within reasonable timeframe after higher capacity drives are introduced.

 

A bit off - I don't know if it's a trend but it seems to be, I haven't seen a single external drive with capacity equal or more than 2TB that doesn't has issues. No matter the brand. It's like we buy them, to just throw our money and you have to have back-up on your backup, because you WILL need it. The only way is to make your own with server-grade drives, or at least WD Blacks or equal. Then comes the question, is the controller in your box of choice good enough?

On topic - unless Helium makes it's way to 2.5" drives, I don't see how we'll get anything but the 2TB Seagate and only Seagate offers. Makes me wonder what the other two of the top three do - WD and HGST (I know that they are one, but there's not a single drive from any of them), especially HGST (also as far as I know they are the one that would make mobile drives in the new venture). They were first to use Helium and there are servers with 2.5" drives. Why, why there no new drives since... forever? The last worthy drive was 7K1000, that was some 4 years ago.

 

If Seagate has an 7mm 2tb 2.5" (P56), then an 3GB in an 9.5mm 2.5" should be possible without increasing data density.

I want a 7K2000 here.. Would upgrade in a heartbeat!

 

What are the issues with the seagate 4tb drive?

 

Same here i have had the Seagate 4tb External for a couple of years, no problem the smart data is all in the green for all that is worth.

EDIT: Sorry this is an 3.5" drive not an 2.5"

John.

 

AFAIK the 4tb (single) drive external came out last year?

 

The 2.5 external seagates 4tb drive is 15mm thick so it's to thick for most notebooks if you try to take apart the seagate external case and use the drive as a internal

 

Sorry i think i am getting my threads mixed up, the Seagate 4TB i have is an 3.5"

John.

 

@Tinderbox (UK) there's a 2.5" 15mm drive too. From the beginning of times till the very present, there was noone adventurous enough to face it without the mask, and see its connector type.

 

An external 4tb 2.5 drive is still fine with me. 2.5 drives are more rugged than 3.5 ones, I'm just wondering how rugged is the 4tb one though. That's a lotta data to cram onto one 15mm drive. And only seagate makes one.

 

All of the ones that come in enclosures seem to have a USB connector on the PCB (both WD and Seagate). There is a seagate 2.5" 4TB bare drive model ST4000LM016 that has a sata interface. But it's about 1.5x as expensive as one of the external drives.

 

What makes 2.5" drives more rugged?

Design (I guess because they have to be used in mobile context).
This was a decade ago: but at that time the shock tolerance of a running 2.5 drive was as much that of a powered off 3.5 drive.
