PCIS-50 PCI controller 4x SATA RAID

A): If the PC does not run with the card or the card is mistakenly detected in “Device Manager”, or if there is a yellow exclamation mark on the driver, or if “Device Manager” reports an error code “Code 10 - The device cannot start”, the card is in conflict with another device in your computer.

B): In most cases, this conflict can be solved by moving the card to another PCI (PCIe) slot, with the BIOS assigning other free resources to the card. If the move does not help, try the card separately, with no additional cards inserted. If the card cannot be moved to another slot, you can reset the BIOS of the computer (by jumper on the board or pulling out the backup battery, we recommend that you note all the original settings and reset everything to the required values). This will cause the IRQ, DMA, and I/O resources to be redistributed.

A): Yes, even a RAID controller can be used to connect separate hard disks.

B): If you do not create a RAID controller in the BIOS, each disk will behave as a standalone unit, just like when plugging into the motherboard.

A): By initializing the disk, you can set the mode in which the hard disk will work

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

A): The newly purchased disk must be initialized before first use.

B): If the new disk is not initialized automatically, open "Disk Management", right-click on the desired disk and initialize it.

A): First try to move the card to another PCI-e slot in case of device conflict. The problem could also be caused by a poor quality or damaged SATA cable.

B): Verify if you have a correctly aligned partition on SSD (using the program that displays this information, such as ASS SSD Benchmark), more about the problem you can find here www.howtogeek.com/256859/dont-waste-time-optimizing-your-ssd-windows-knows-what-its-doing/. The next step should be to verify if the TRIM is working, preferably by using the SSD TRIM check tool program that can be downloaded at forums.anandtech.com/showthread.php?t=2302578 where the usage is described. We recommend a time delay of more than 15 seconds.

A): This will depend on the PCI-e bus of the motherboard used. If your motherboard does not have a PCI-e bus of at least ver. 2.0, the use of the controller will not be beneficial.

B): The PCI-e revision 1.0 (1.1) has a maximum bandwidth of 250 MB/s on a single line, the revision 2.0 has a theoretical bandwidth of 500 MB/s on a single line, and practical about 400 MB/ s (after subtraction of the bus itself). So if you connect SSD to int. SATA II controller, the limit will be 300 MB/s, if to SATA III controller with revision 2.0, the limit will be about 400 MB/s.

A): The lead time is naturally longer by the time it takes to detect the controller and connected disks. The start time can be shortened in the MB BIOS by enabling the "Quick Boot" feature. For newer boards, this feature is labeled "Fast boot". The lead time depends, of course, also on the disk used for the SSD/HDD operating system and the number of peripherals connected to the computer.

B): In the case of newer motherboards, it is more practical to use the spin down (instead of turn off) feature.
