Hello there,

I have an ASRock B450M Pro4-F, AMD B450, S AM4, DDR4, SATA3, Dual M.2, 2-Way CrossFire, Realtek GbE, USB 3.1 Gen1 A+C, MicroATX and a
Sabrent 1TB Rocket NVMe PCIe M.2 2280 Internal SSD High Performance Solid State Drive (SB-ROCKET-1TB).

I was going to split the drive into two partitions, with one for Windows and another for documents. I'm starting to get the impression this isn't conventional any more.

Now I'm thinking I should get a smaller Sabrent 256GB Rocket NVMe PCIe M.2 2280 Internal SSD High Performance Solid State Drive (SB-ROCKET-256) just for Windows and use the other drive for storage.

Will this work based on the Motherboards specifications?

Storage
  • 4 x SATA3 6.0 Gb/s Connectors, support RAID (RAID 0, RAID 1 and RAID 10), NCQ, AHCI and Hot Plug*
  • 1 x Ultra M.2 Socket (M2_1), supports M Key type 2242/2260/2280 M.2 PCI Express module up to Gen3 x4 (32 Gb/s) (with Matisse, Picasso, Summit Ridge, Raven Ridge and Pinnacle Ridge) or Gen3 x2 (16 Gb/s) (with Athlon 2xxGE series APU)**
  • 1 x M.2 Socket (M2_2), supports M Key type 2230/2242/2260/2280 M.2 SATA3 6.0 Gb/s module

*M2_2 and SATA3_3 share lanes. If either one of them is in use, the other one will be disabled.

**Supports NVMe SSD as boot disks (M2_1 only)
Supports ASRock U.2 Kit

Thanks for your help.
 
Solution
It looks like it has two physical slots, if you install on both, does it divide the bandwidth by two? Basically is it possible but will affect performance?
First (NVME) slot is tied to CPU, the other one to chipset so they don't share anything between them. First one shares PCIe bandwidth and lanes with CPU.
