Does dual (or triple) SSD "DVD bay" exist ?

Hi, I would like to know if there is such a piece of hardware that allow the use of multiple M.2 or mSata SSD into the SSD drive bay, since this bay use only one Sata interface I think that this is possible by using a sata controller built-in the "DVD bay" that raid 0 them in order to get an insane capacity out of the "DVD bay".
I know that these thing exist but it is an USB enclose with sata controller inside that raid 0 two M.2 SSD.
Thanks you all

 

Buy something like this:
https://www.amazon.co.uk/StarTech-com-Dual-SATA-Adapter-RAID/dp/B018AOZ9QM

And a DVD bay adapter like this so you can connect it to the laptop:

https://www.amazon.co.uk/Universal-Optical-Laptops-SAMSUNG-TOSHIBA/dp/B008KS6V0W

These last adapters have variable sizes. Make sure you buy one that fits you laptop and you laptop actually has support for a disk in the DVD bay instead of a DVD player/writer

BTW the DVD tray usually its SATAII not SATA3. So you will see a performance loss

 

When I looked into this for my t440p, at least for the mSata devices raid 0 netted 0 performance gains. Even on sata 3 interfaces.

 

It probably used JBOD versus RAID 0. That is generally the case for self-contained adapters that combine multiple drives and spanned in a way to function as a single storage device that connects on a single SATA port. JBOD is concatenation, not really RAID in spite of it being referred to as RAID, even by companies that sell those adapters.

 

From the reading back at the time it basically came down to worse performance than just running them individually. The problem came down to the on board controller these 3rd parties used not being up to the task.

 

Yes

Sata3 is limited to the ~550MB/sec cap too.

Also, unless you already have the drives, in most cases one single double capacity drive is available for around the same (usually actually cheaper) than two half the size. And has two less points of failure (the 2nd drive, and the probably yumcha "raid" board).

 

Right total throughput would be limited but some still liked the idea of increasing the random 4k throughput, but even with that it was still worse off than a single drive. It was better suited for JBOD.

 

Thanks you all, I was just wondering about an three m.2 ssd enclose that fit in the DVD bay for those who want more than 4Tb on a single sata interface, for me I will stick to normal SSD
