I heard the Motherboards are running at 10Mb/s so don't you need 2 SSD drives for that. Can you hook up 2 SSD drives together and get twice the data transfer rate?

I'm not sure I understand what you are trying to do. Two drives can be configured as a RAID array but they would not receive data any faster than a single drive. The advantage of multiple drive arrays is that you get data redundancy which means that if a drive fails you may or may not know it happened. There would be no data failure.

A 10MB pipe will transmit 10MB be it to a single location or to a multi disk array.

Hope this helps

I'm sorry I meant 10 Gb's

certain RAID arrays will offer slightly better performance, but with SSDs Im not sure youd really notice it to be honest with you. RAID 1 with redundancy is great if one drive fails, a RAID 0 (striped) will boost, but I doubt youd see the difference. And if one drive failed, youd lose everything. With my setup I have a single SSD as my boot drive, and 2 standard 500 gig hard drives that Im planning on putting in RAID 1 (havent yet)

I'm not talking about RAID, I'm asking about parallel Drives like in parallel CPU's in super computers. I understand that the Motherboard allows for 10 Gb's of data flow. So my question is how? Also is it possible to have parallel drives for faster data transfer?

You are either talking about RAID or you're talking about just having two separate drives in the machine.  If you want to combine the drives you are either talking RAID0 or RAID1.  RAID0 may give you a slight speed increase, but as the_patriot11 you probably won't notice it with SSDs.  TRIM support, also known as garbage collection, may not be supported in a RAID configuration.  RAID1, drive mirroring, is to protect against hardware failure.

 

RAID is not a backup solution and will not protect you if you get hit by one of the new encryption ransom malware infections.

Assuming you mean is there a way to have a single SATA port address two drives, then no, SATA is specifically designed for a single drive per port. However as the interface theoretical maximum throughput rises, drives with matching performance come along to make use of it. There's no point manufacturers producing the faster drives until the interfaces get established in the market.

 

When SATA 3.0 was the current standard, 6Gbit/s gave approx. 600MB/s and readily available consumer drives have risen to around 560MB/s read performance. However on faster interfaces like PICe, you can get drives like a Mushkin Scorpion, with around 4 times the speed. No doubt SATA 3.2 SSDs will start to appear to take advantage of the faster interface as it becomes the norm.

They have the M.2 for the SSD drive so would that give me better data transfer rate than a standard SSD drive?

Looks like the potential is there but only if both SSD and slot implement 4 lanes:
