Chapter 9 Review: Hard Drive Technologies Flashcards
This sata connector is used for external hard drives:
eSATA
How do you differentiate between two PATA drives on the same cable?
You set jumpers on the individual drives to determine master and slave
Potential causes of continuous system reboot loops include:
- Overheating
- Corrupt OS
- Hardware failure
- Misconfigured OS
What are typical SSD form factors?
1.8, 2.5, and 3.5 inch
RAID 5 is also known as?
Disk striping with parity
How many drives minimum are required for a RAID 5 array?
3
This RAID provides 0 redundancy, but improves speed
RAID 0
This technique uses two disks and two controllers:
Drive duplexing
True or false: a 7200 RPM HDD will generate more heat than a 5400 RPM HDD
True
How many PATA hard drives can you have on a system with two PATA hard drive controllers?
4
ATA-3 introduced _____, an internal drive program that tracks errors on a hard drive to predict potential drive failures
S.M.A.R.T
How many failures can a RAID 1 and 5 array withstand while still remaining functional?
1
How many failures can a RAID 10 array withstand while still remaining functional?
Up to 2
Disk striping with distributed parity is also known as:
RAID 5
Cable select requires a special cable with a pinhole through the wire. Does position of the drives on the cable matter?
Yes
List the RAID levels in order of minimum number of drives required
RAID 0 (2) RAID 1 (2) RAID 5 (3) RAID 6 (4) RAID 10 (4)
