2 ssds set up as hybrid

So my dad told me if i get 2 ssds and set them up to copy half of each program it would be much faster thanjust having one ssd? Is this possible and does it make it faster than just having one?

It's called RAID <number> and here's a video on it:

It makes it "twice" as fast, but also twice as likely to fail (if either drive fails you lose everything). The speed boost is theoretical, and wouldn't quite be twice as fast. But unless you're doing some write critical tasks (which are actually limited by the speed of a single SSD) then RAID 0 really isn't worthwhile.

It is called RAID 0. It stripes data evenly across drives in the array. With two drives, it theoretically doubles the performance of a single drive, though it doesn't scale perfectly, and actually handles smaller size files worse than a single drive would. 

 

You also double the chances of losing data if you put two drives in RAID 0, though. If a single drive in the array fails, you lose all of the data on any drive in the array, 

 

EDIT: The speed benefits of RAID 0 are only really noticeable during large file transfers. For everyday use, and what most consumers do, the speed benefits are not worth the increased changes of loss of data. 

 

RAID = Redundant Array of Independent Disks/Drives. RAID 0 doesn't comply with the redundancy part, though.

its called raid 0

and its not worth the trouble

you will not see any improvement since one SSD is already fast enough for pretty much anything a regular consumer does

You won't notice a significant performance increase in regular tasks by putting two SSDs in Raid 0, and two drives in Raid 0 are essentially one drive, so if either one fails, it'll take all your data with it. In RAID 0, data is 'striped' across two drives, and thus, the increased risk of failure makes it a bad gamble.

While there are no moving parts in an SSD, the semiconductor components can fail. For example, a NAND die, the SSD controller, capacitors, or other passive components can -- and do -- slowly wear out or fail entirely.

SSDs have a limited number of write cycles. Eventually, it cannot be written to anymore as the NAND has been worn out. 

 

There's also chances of electrical damage, faults in the PCB and a few other things. As with pretty much all electronics, they get worn out with age and use.
