Hello,
I'm looking to increase my Mac Pro 5,1 SSD Read/Write speeds for an all around better workflow/user experience.
Is anyone using a PCIe raid controller in raid 0 to achieve greater R/W performance, if so what speeds are you getting and what card(s) are you using?
At present, I have 4x SATA3 SSD's in software raid 0 using the onboard 4x SATA2 ports, the SSD's are independently capable of 500MBps R/W via a SATA3, using the onboard SATA2 ports with my 4x SSD's I am achieving under 600MBps Read/Write speeds, which is ok but not all that great considering the independent R/W of the SSD's.
I'd rather stick with my current 2.5 SSD's then move over to M.2 with an M.2 PCIe card, plus it's hard to find AHCI M.2 sticks at reasonable prices, if at all.
So what are my options here? I would like to be achieving at least 1GBps reads & writes.
I'd like to see benchmarks of cards, some PCIe 2.0 SATA3 raid cards hit a wall in raid 0, I'm looking for a card that will utilise the full speeds of all my SSD's.
Reference of card that does raid0 but hits a wall: 'Finally, we tried RAID0 with three C300 256GB SSDs..."
