Housing two 2.5-inch hard disks in one 3.5-inch drive bay?

[Man-wai Chang to The Door (24000bps)]

Found such a toy in local computer shopping arcade.

Is it gonna kill both hard disks by heat?

2.5 inch disks usually generate a lot less heat than a 3.5 inch disk, so
my guess would be no.

I'm considering one of these, or perhaps 4x 2.5" in a 5.25" bay. Two
2.5 inch 500 GB disks will be around twice the price of a single 3.5" 1
TB disk, but as far as I can see they will be quieter and lower power
(even with two of them), and faster (using raid0).

That's also my curiosity!

Unlikely, 2.5" drives are pretty good heat wise.

Perfectly possible to deal with the heat with a fan.

My Samsung 3.5" 1.5TB drives are completely silent, you have to
listen very carefuly to see if they have spun up in a USB docking station.

MUCH better value and speed too.

I like mine too, Samsung ecogreen 5400 1T. Value is median, quality
and reviews for Samsung are higher up to 1.5T. Above, 2T, only
Hitachi is going for the value -- 2T $134 rebated to a $110 1.5T
Samsung. 2T for pushing $200 with the rest will have to wait for
better values. May do another one after awhile, 1.5T WD's audiovisual
HD might be a choice, (possibly then a Hitachi after WD), although
with WD and XP that involves getting into WD's new 4K sector
alignment. Win7 is already implemented. For XP, not too major, more
difficult to actually understand, although WD does offer a couple easy
ways of going at it with, either their software or a XP-compatibility
jumperpin on the HD -- unless someone were regular type in server fare
with command line utilities (*nix) for adjusting large-drive
alignments. 4K sectors look to be the writing on the wall past 2T -
though 4K may not be the standard sector size until 2013-14.

Notebook drives: Unlikely.
Server drives: Likely.

All in all, I think I'll be going for 3.5" disks. While 2.5" have the

potential for being faster in that you can fit more into a given space
and run them in parallel, it's just not going to be worth the money.

I guess we need to wait for 2.5-inch drives to get mass production.

I've had at least two notebook drives die of a heat death. One time it
was in one of those slim-line USB cases, and another time it was inside
a laptop itself.

I haven't paid much attention to disk drive noise or power
requirements before, but I'm planning on having several drives on a
new machine (to play around with raid) and so the total drive noise
is (perhaps) going to be noticeable. It's useful to hear people's
experiences with modern drives - "completely silent" is more helpful
than "2.5 Bel" on a web page of drive specifications.

There's no argument about value.

I had a look at some details of drives on Samsung's website, and was
somewhat surprised by some of the specification details. I had
thought that the seek time for 2.5" drives would be lower than for
3.5" drives since the maximum movement distance is smaller. Apparently that's not the case. And the disk-to-buffer
transfer
speed is almost twice as fast for the 3.5" disks. It also seems that
there is little difference in the noise, although the the 3.5" disks
take more than twice the power of the 2.5" disks.

All in all, I think I'll be going for 3.5" disks.

Yeah, I do, mainly because they are so much cheaper.

I do buy quite a few, mainly they are for overflow from the PVR.

While 2.5" have the potential for being faster

I dont care about the speed, what I need is best $/TB and nice and
quiet and dont get warm. I use the greens for the PVR overflow.

in that you can fit more into a given space and run them in parallel, it's just not going to be worth the money.

Yep, and more hassle than a single physical 1.5TB drive too.

I put them in USB/esata docking stations.

Yes, I must sincerely concur (on the quietness issue, especially). During
nearly six full years of use, my main computer's pair of Samsung SP1614N
160GB (PATA) hard disks have remained practically silent.

Not so, for any of their Western Digital or Maxtor predecessors, I might
add! Those babies could be heard clicking away, regularly.

Incidentally, Rod...did you notice that I didn't edit the message I just
replied to? (I know how you hate it, when previous text is deleted.)

Yeah, my older samsungs too.

Yeah, me too. I did mostly use WDs before the samsungs.

Yep, thanks for that.

Yeah, particularly when you tend to reply rather later than the post
you are replying too, harder to remember what was in it if its edited.
