What are the steps in install an SSD card in the M.2 slot
1. Measure the card length and determine which screw hole to use 2. Slide the card straight into the slot, but not from an upward angle. Determine if the b-key (left notch) or m-key (right notch) should be used. 3. Install one screw into the standoff (spacer like is used for motherboard). Do not overtighten. 4. Star the system. Check BIOS/UEFI set up to make sure the card is recognized
Steps to create a RAID 5
1. install 3 SATA drives 2. Enter BIOS/UEFI. Verify drives. Select option to configure SATA then select RAID 3. Reboot and enter RAID configuration utility (ctrl+I) 4. Select "Create RAID Volume" 5. Select RAID5 Parity. (there is no need to select disks since all 3 are required) 6.Select the value for the strip size (32, 64 or 128 KB) 7. Enter volume size. You don't have to use the entire available space. What's not used can be configured as another array. 8. Select "Create Volume", say yes to warning all data will be erased.

low-level formatting
A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.
What is necessary for best RAID performance
All drives should be identical in brand, size, speed and other features
Why do hard drives tend to slow down over time? ~Drives can reach full capacity, which hinders where data can be written to the drive. ~SSDs must erase a block before a block can be written. ~Magnetic drives take longer when having to read data from noncontiguous locations on the drive. ~All of the above
All the above The hard drive can slow down when it almost reaches its maximum capacity. SSDs need to erase previous data to write new data. Magnetic drives can have problems with fragmentation.
You want to install an SSD in your desktop computer, but the drive is far too narrow to fit snugly into the bays of your computer case. Which of the following do you do? ~Install the SSD in a laptop computer. ~Buy a bay adapter that will allow you to install the narrow drive in a desktop case bay. ~This SSD is designed for a laptop. Flash BIOS/UEFI so that your system will support a laptop hard drive. ~Use a special SATA controller card that will support the narrow hard drive.

Partition and format the drive using Disk Management utility to prepare if for first use
Error "Hard Drive not Found"
Possible solution check all cables from drive to motherboard.
You have two matching HDDs in a system, which you plan to configure as a RAID array to improve performance. Which RAID configuration should you use? RAID 0 RAID 1 RAID 5 RAID 10
RAID 0 It is the simplest technique which used 2 or more drives to increase the disk space of the system, which increases performance.
4 most common types of RAID
RAID 0, RAID 1, RAID 5, RAID 10
Which of the following situations allows for data not to be lost in a RAID array? RAID 0 and one hard drive fails RAID 1 and one hard drive fails RAID 5 and two hard drives fail RAID 10 and three hard drives fail
RAID 1 and one hard drive fails It is a kind of mirroring which copies the date on one drive to another drive. So if 1 drive fails the data is not lost

Explain how a DVD manufacturer can advertise that a DVD can hold 4.7 GB, but Explorer reports the DVD capacity as 4,706,074,624 bytes or 4.38 GB. ~Manufacturers are allowed to overadvertise their products. ~The manufacturer measures capacity in decimal and the OS measures capacity in binary. ~The actual capacity is 4.7 GB, but the OS requires overhead to manage the DVD and the overhead is not included in the reported DVD capacity. ~The DVD was formatted to have a capacity of 4.38 GB, but it could have been formatted to have a capacity of 4.7 GB.
The manufacturer measures capacity in decimal (base 10) and the OS measures capacity in binary.
