Review on High Point RocketRAID 640L Internal 4 SATA Port RAID Controller -Lite Version: PCI-Express 2.0 x4 SATA 6Gb/s by Ruben Jamrock

This RAID card offers port multiplier protocols that allow up to 20 HDD/SDD/HSDD drives to be connected together as a JBOD or as a RAID 0/1/5 /6 and to mount etc. We use it with our Microsoft 2019 server and Storage Spaces built-in disk software and as long as you're not using Windows 2012 Storage Spaces works great. Please note that there are some issues in Storage Spaces 2012 that caused significant data loss on our system, but these issues were fixed in 2016 and will continue to be addressed in 2019. stepping on top of each other to prevent unauthorized downloads - annoying when you do a lot of remote downloads. When we tried to get tech support the company was absolutely useless for two reasons: 1) We were told that the cards don't support port multipliers even though the boxes have that terminology, the website has that terminology and we have it just fine system works and has been in operation for 10 years (various incarnations).
