Some of Intel chipset ATX mb with 8 SATA (3/6Gbps) ports are:
ASRock Z77 Pro4 (a single PCIe 2.0/3.0 x16)
ASRock Z77 Extreme4 (dual PCIe 2.0/3.0 x8)
ASRock Z77 Extreme6 (dual PCIe 2.0/3.0 x8)
MSI Z77A-GD65 (dual PCIe 2.0/3.0 x8, Intel Gb LAN)
ASUS P8Z77-V (dual PCIe 2.0/3.0 x8, Intel Gb LAN)
ASUS P8Z77-V PRO (dual PCIe 2.0/3.0 x8, Intel Gb LAN)
I emphasized PCIe 2.0 x8 because the latest 8-port SATA 6Gbps host bus adapters such as
- Supermicro AOC-SAS2LP-MV8 (Marvell chip
, but rock stable in my server 24/7 for a year)
- IBM ServeRAID M1015
- LSI SAS 9211-8i
require PCIe 2.0 x8 slot.
If you don't do CPU intensive tasks such as transcoding, Celeron G1610 dual core IVB processor, ~$45, is enough.
