Single physical SSD acting as two drives in RAID0???

antares · 10 Dec 2012

This is crazy, and never heard of. I always thought that RAID 0 configuration is possible using two identical physical drives. I bought this Sony Laptop. If you go down to the Hard Drive Storage section you see you can customize it with four different options. I chose the 1st one (750GB mechanical drive). However you can see that the last two options involve RAID 0 (128x2 or 256x2). I was wondering where to install the 2nd drive as there is only a single drive compartment with a single SATA ribbon connector when you remove the back cover. I called Sony Tech Support and this is what they said: "You can only physically install a single SSD. The RAID 0 options involve a single physical SSD that inside has two chipsets in RAID 0, in other words, it's a single physical SSD that acts as two drives". Of course I never heard of this, does this exist?

I have never heard of that. But, is it possible, probably. A Revo Drive is a desktop SSD that uses a PCIe port, but is actually 3 drives in Raid 0. So, while I have never heard of it, I would imagine if they can do that with a PCIe drive, it could be done with an SSD. But, I have never seen one for sale or advertised. I wish he had have given a link to some data on it.

That is unless he was talking about a hybrid hard drive similar to the Seagate momentus, which is a regular hard drive with a small SSD in it to boost the hard drive speed.
