I have a new Z240 Workstation with Xeon E3-1289 v5 @ 3.70GHz64GB memory; Windows 10 PRO; two 1TB PCIe SSD drives; one 1TB SATA SSD drive connected to a SATA Port on the motherboard. There is one open SATA Port on the motherboard. Slot 1 (PCIe x1) is Open; Slot 2 (PCIe x16) is the graphics card; Slot 3 (PCIe x4) ; Slot 4 (PCIe x4) is a Thunderbolt 2 card. Now using this system as a development, training, and test system running multiple virtual machines in VMware Workstation.
I want to add 3 SSD drives and plan for more. I wondered how to get the highest performance for a LOT of I/O from multiple simultaneous Virtual Machines. Options: Add 1 SSD to the open SATA port on the motherboard and some combination of the following; Add another SATA Controller to the empty slot 1 and populate with SSD Drives; Replace the Thunderbolt card with a new SATA 3 Controller or a USB 3 Gen 2 card. Or replace the Thunderbolt card with USB 3 Gen 2 (10Gbit). Maybe all of these?
