Two SSD in place of an ODD?

Given the size of a CD and the size of a caseless SSD, physically you could squeeze in two SSDs no doubt. A multiplexer, if necessary, is cheap. Anyone tried doing this?

This alas is USB http://www.acard.com/english/fb01-p...type1_title=Portable Storage &type1_idno=12#6 and 6.5" inches but.. it's close.

 

Even the tallest ODD are 15mm, 2 x 7mm SSDs (with their spacers removed), I doubt you'd be able to fit the SSD unless you are talking about those 1.8" mSATA SSDs with the bare PCB...but mSATA isn't a standard that is easy to find these days for ODD caddies.

 

I am talking side by side. Take Hot Swap Backplane - 2x 2.5" SATA/SAS HDDs + SATA Optical Drive | StarTech.com Canada this and throw out the top half.

 

still no , how about you take a look at the power consumption ?

 

With a desktop optical drive bay it's possible, but with mobile optical drives you're left about 10mm short.

 

Normal 2.5" size drives will not fit. Maybe if you take the cover off it will fit though.

2 SSD's are going to use a lot less power than 1 DVD drive.

 

Except an optical drive is idle most of the time (and therefore powered down). When it is spinning, it uses about 2.5W of power. When it is actively reading data, it uses about 5.0W of power.

An SSD is always on. Most SSDs use ~1.0W idle, and ~2.5W when actively reading / writing.

Having 2 SSDs will consume about as much power as a single optical drive that is spinning (both spinning-idle and spinning-read). However, when you take into consideration that an optical drive is actually powered off most of the time (whereas an SSD is always powered on), then you actually lose battery life by going with 2x SSDs.

 

But the drives don't have to be left in an idle state; they can be shut off. And I'm pretty sure lots of SSD's use far less than 1 watt when at idle.

 

that can't be done , even usb devices are still powered when you eject them unless you unplug .
internal SATA devices are not designed to be completely shutdown by command because they are not supposed to.

even DVD drives , when it doesn't contain any CD there are parts that are still active such as the dvd eject button.

 

Man, I wanted to do the same thing!

First of all its totally possible especially if you can solder.

The problem for me is, hot swapping. You still can't use both at the same time. Its just silly.
Theres no such thing as a SATA splitter or a compact RAID controller that uses 1 SATA port, apparently. I bet theres something out there but then you'd really have a hell of a time getting it to fit.

The funny thing is you could easily get 2x SATA out of an IDE port but that would just suck, lol.

 

I think you'll be able to put 2 Samsung SSD Series 830 series in. They are only 7mm thick.

 

Yeah.. the SATA multiplexer part would be an issue. I'd suggest check if you have an e-SATA port or a docking connector with e-SATA on it and then wire that to your ODD as a second SATA connector.

Then can just deshell your SSDs and them two stacked on top of each other. The benefit there is you'd get twice the bandwidth into the I/O controller. Still, you may simply wish to keep it simple and just get one large SSD to be placed in your ODD.

You could consider doing the same with a USB 3.0 port but there you'd need to add some USB 3.0 to SATA adapter.

 

I knew I was missing a word! The word is MULTIPLIER and this is looking VERY FEASIBLE:
SYBAUSA - SY-PEX40045 >> 1:2 (2x1) Internal SATA II Port Multiplier (PM), Bracket Mounting, RAID 0, 1, JBOD

I think its ESATA but thats basically SATA.

This is exciting....

Also how could you NOT fit 2 stripped down 1.8" drives? Stacked on top of each other, this definitely looks like it would leave room for the port multiplier (not with this particular caddy of course):

 

If you removed the casing then 2x2.5" might even be possible, I hadn't thought about that previously.

 

yes this CAN be done. and it's not hard. it would be very easy. you just have to find some space. you can remove the ssd enclosure or just use 1.8" ssd's. it will certainly fit. or try to use 7mm 2.5".
It will have some problems for sure but yes it works.
You probably won't be able to use an enclosure, you have to make it your own, ducktape or foam will do the trick. you can also remove the plastic part from the ODD if you don't want that part to be exposed. there are hundreds of ideas about how to do it. it's easy you just need to fit 2 parts in one place.
another problem would be the connection. probably you can't use the odd interface or even if you could find an adapter it would only work for 1 disk.
you can even put those ssds in RAID! you can even get mini pci-e to sata converters and get a cable to connect. there are many options.
It will work. Don't let narrowminded people tell you otherwise.


mini pci-e to 2x sata with built-in RAID support

 

If you remove the enclosure, then you might even be able to fit 4 in there. With the casing on, a 2.5 inch drive won't quite fit side by side, but I would assume that by taking off the casing you would lose at least 5mm off the width of each drive, meaning they would fit side by side.

With 7mm drives, you still won't be able to stack them on top of each other without removing the casing, standard notebook optical drives are 12.7mm which still isn't enough. You can get slimline drives, but I've never heard of anything bigger than 12.7mm, there's also the fact that your laptop would have to suppport something that big.

 

Wow you found a two port multiplier! I searched the hell out of the web but couldnt find one. http://www.newegg.com/Product/Product.aspx?Item=N82E16816124049 25 bucks, who's the first to try ?

 

Look, http://forum.notebookreview.com/sol...half-slim-sata-solid-state-disk-reviewed.html this is "ridiculously tiny 5.4cm (2 ⅛ in) wide by 4cm (1 ½ in) long". Would make it absolutely easy to fit two of them

 

Be careful, start saying stuff like that and niff is going to try and stack them 2x2 for 4 ssds in the bay.

 

How would you power it? Looks like it's running 12v and 5v off the 4-pin molex. That image that __-_-_-__ posted should work. Try here: http://www.amazon.com/StarTech-com-Express-Internal-Controller-MPEXSATA22I/dp/B004NNRRN8

 

That's dual-channel SATA (supports RAID 0,1), you'll still need to get power from somewhere. It's meant for small ITX MoBos. I'm looking at it even before it was released, and I asked the tech support handful of questions. BTW my Intel is like 5mm thick at the connector and the rest of the drive is 2~3mm (stripped down of course). I guess you could stack two in a caddy, but then comes the wiring...
