A+ Hard Drives

____ makes addressing any form of mass storage easy, and that’s how the operating system interacts with the mass storage, via blocks

When a computer starts it does a _____ test, then looks for a bootable OS on a drive

___comes in 3.5,2.5 and 1.8 sizes

The dominant ATA today is

We use advanced technology attachment for what?

Esata(external SATA) is not as popular today because of USB storage devices. True or false?

__ use spinning platters to store data via magnetism and read/write heads

The original ATA standard defined a very specific series of commands for the CPU to communicate with the drive controller. The current drive command sets are AHCI and NVMe. The SCSI command set is still around as well, though primarily in the server market.

Current versions of Windows support the Advanced Host Controller Interface (AHCI), an efficient way to work with SATA HBAs. Using AHCI unlocks some of the advanced features of SATA, such as native command queuing and hot-swapping.

Native command queuing (NCQ) is a disk-optimization feature for SATA drives. It takes advantage of the SATA interface to achieve faster read and write speeds that are simply impossible with the old PATA drives.

while SATA supports hot-swapping ability, the motherboard and the operating system must also support this.

AHCI mode is enabled at the CMOS level (see “BIOS Support: Configuring CMOS and Installing Drivers” later in this chapter) and generally needs to be enabled before you install the operating system. Enabling it after installation will cause Windows to Blue Screen. How nice.

Each SATA variety is named for the revision to the SATA specification that introduced it, with the exception of SATAe:

• SATA 1.0: __________

• SATA 2.0: __________

• SATA 3.0: ______&&

• SATA 3.2: __________ also known as SATAe

SATA’s ease of use has made it the choice for desktop system storage.

EXAM TIP The CompTIA A+ 1001 exam objectives refer to the 40-pin PATA ribbon cable as an IDE cable. They’re the same thing, so don’t miss this one on the exam!

Today SCSI uses serial connection like SATA. Although SCSI is mostly used for servers today

_________ hard drives provide fast and robust storage for servers and storage arrays today. The latest SAS interface, SAS-3, provides speeds of up to 12 Gbps. ___controllers also support SATA drives, which is cool and offers a lot of flexibility for techs, especially in smaller server situations. SAS implementations offer literally more than a dozen different connector types. Most look like slightly chunkier versions of a SATA con
