I’m building a new computer and I use an SSD to load the operating system and another volume with WD Red drives on RAID 0 Red for files.
I’ll use a backup solution in a 4TB external HD, so I’m choosing the RAID 0 for more performance. Note: My motherboard supports up to 4 HDDs in SATA III 6 Gbps (Asus Rampage IV Extreme).
My question is whether it is worth doing RAID 0 with 4 HDDs WD Red, or if the gain with 4 HDDs is very small in relation to use RAID 0 with 3 or 2 HDDs. Whit 4 WD Red on RAID 0 can I get close to the transfer rate of the SSDs that are around 400 MB/s?
Has anyone done tests with 2, 3 and 4 HDDs on RAID 0?
