Raid?

Can I put my 4 480gb  hyperx savage ssds and a Samsung 128gb 850 pro in a RAID 10 array?

raid 10 only works in multiples of 4, so you 4 hyperx ssds will work, but you cant include that samsung drive

Hey potato-builder,

 

As @mikat explained, RAID10 requires 4 disks or a multiple of four. You can, theoretically, do RAID10 with only two drives, but it wouldn't be stable or safe. 

furthermore, do have in mind that all drives in a RAID array would be limited to the size of the smallest and the speed of the slowest, meaning if you put the 128GB SSD with the 480GB ones, all of the will be limited to 128GB in storage capacity.

Actually, that's incorrect. You need a minimum of 4 drives and multiples of TWO, if you have use two-way RAID1 arrays (meaning that you have a pairs of drives in RAID 1 and you stripe across those pairs in RAID 0). But you both are correct in saying that the Samsung drive is best left out.

 

@potato-builder, what is your use case? Running SSDs in RAID0 is not always ideal, depending on what it is you want to achieve.

My bad, I meant to write 4 or more but still an even number (multiple of two). Thanks @MG2R

well @MG2R I wanted to get really fast load times like in raid 0 but I still wanted really good reliability like in raid 1 so naturally I just went with raid 10

RAID0 gives you great sequential performance, if your SATA host can handle it. I used to run two SSDs in RAID0 and got over 1 GB/s sequential reads and writes.

 

See how I made that "sequential" really freaking obvious? That's because you need to pay attention to your work load. Running an OS and programs is mostly random I/O which won't improve much when putting your drives in RAID0 on the integrated RAID controller. Your day-to-day working speeds won't improve noticably. That's why I replaced my RAID0 with a single big SSD.
