Cards in this deck (27)
- 1Storage Device that reads/writes to Hard DiskHard Disk Drive - technically seperate from HDD, but generally interchangable
- 2Circuitry to communicate with CPU, can be built into drive or expansion cardDisk Controller
- 3configure old hardware by shutting off electric circuitjumper
- 4Common Hard Drive Speeds (RPM)5400
7200
10,000
15,000 - 5What does PATA stand for 4 AKAsParallel Advanced Technology Attachment
IDE
EIDE
UDMA
ATA - 6HD Technology with controller built into drive, drive type set in BIOS, jumpers to set config how many channels, how many devices eachPATA
2 channels, 2 devices each - 7What does SCSI stand forSmall Computer Systems Interface
- 8HD tech with no controller built in, seperate bus on computer seperate ID for each device how many devices, 1 reserved for _____SCSI
up to 8, 1 reserved for Host Bus Adapter - 9SATA stands for.... How many devices per channel? is hot swapping allowed?Serial Advanced Technology Attachment
1
yes - 10Introduced modes 3+4 how many conductors? How many Pins? Supports up to __ ?BsATA5 or UDMA /66
80 conductors, 40 pins
137 GB - 11Serial instead of parallel signaling, smaller, thinner, more flexible standard Transfer rate?SATA
150MB/s - 12SATA2 transfer rate 1AKA300MB p/s
SATA 3GBps - 13SATA standard that doubled transfer rate for SSDSATA 6GBPs
- 14Scsi-3 bu speed for 8bit? 16bit? max cable length? 2AKAs20MBps / 40MBps
3 meters
ultra scsi or fast-20 - 15SCSI standard that added cyclic redundacy check and domain validation bus speed? 1AKAUltra-3 SCSI
160MBps
Ultra-160 - 16Ultra 320 bus speed320 MBPs
- 17SCSI standard that pushes limits of LVD signaling, speeed, cable length bus speed 1 AKAUltra 640
640 MBps
Fast 320 - 18SCSI standard that is fast, hot swappable, and has fault isolation very priceySerial SCSI
- 19Stores data optically rather than magnetically. written by pressing or burning with lasersoptical disc
- 20Recessed areas of optical disc? Raised areas?pits and lands
- 21How much can a blu ray hold? how much can experimental version hold?50GB
up to 200 GB - 223 types of Blu ray discBD-ROM
BD-R
BD-RE (written and erased) - 231 difference between DVD + R and DVD - R+ not approved by DVD forum
- 24Optical Disc capactiy (per side) and transfer rate CD DVD BLU ray (no rate)cd = 700-860 MB / 150 kbps
dvd = 4.7 GB per side / 600kbs-1.3 MBs
BR = 25 GB per layer - 25File system of CD File system of Blue rayUniversal Disk Format
UDF
UDF v 2.5 - 26stores data magnetically, reads sequentially, linear filesystemtape
- 27Flash storage technology with no moving partssolid state drive
