If desktop system doesnt have an eSATA external connector or need more eSATA devices, you can install eSATA HBA ______card or eSATA internal to external slot plate.

PCIe

Software RAID means operation system is in charge of all _____functions. Works for small RAID solutions but tends to overwork OS easily creating slowdowns

RAID

To start raid is to connect two hard drives to create a RAID array. Specialized _____ controllers to support RAID arrays.

RAID

_____(redundant array of independent (or expensive) disk. - using multiple drives to protect data and increase speed.

RAID

The latest version _____ (SATA Express) or SATA 3.2 ties capable drives directly into the PCI Express bus on the motherboard. SATA has unique connectors but provide backward compatibility.

SATAe

ATA 3 introduce (Self Monitoring And reporting technology)internal drive program that tracks errors in the drive. Examined with SMART reader software and helps predict potential hard drives failure.

SMART

_____ (Solid State Drive) use memory chips to store data instead of all those pesky natural spinning parts on the platter based hard drives.

_____ describe two or more drives working as unit.

array

If the controllers are enabled and the drive outs properly connected through a process called _______ takes all the work out of configuring hardrives.

auto detection

Trouble hard drives installation use ____feature CMOS set up utility. If the system did not see the drive something is wrong with the hardware configuration. Either a device has failed, hardrive dont have power, plugged in cable improperly or messed up connectivity issue.

auto detection

Many PATA hard drives use a jumper setting called ____ than master or slave. position of the cable determine which drive will be master or slave. For two drives set both drives as cable select.

control panel

if you really want to make data safe use two drives each on a separate controller is called _____.

disk duplexing

Installing drives make sure you have the right ____, configure the drive properly and test to see if its running properly.

drive

Air flow can make or break your system stability especially when adding new _____ that increase temperature. Hot systems lock up.

drives

SSD can be PATA, SATA, ____ or USB for desktop

eSATA

______(External SATA)extends the SATA bus to external devices.

eSATA

Get into the habit of tying off non aerodynamics cables, adding front fans when systems sysyem lock up and maker sure ____ runs well.
