- 1What are ROM optical storage devices?Read Only Memory
Came in the form of disks that had permanent unchanged storage
Legacy storage tech - 2CD-ROM’sCompact Disk Read Only Memory
700MB capacity - 3DVD-ROMDigital Versatile Disk-Read Only Memory
4.7GB (for a single layer)
8.5 GB (for a dual-layer DVD) - 4BLu-Ray25GB (single layer)
50GB (dual layer) - 5CD-RWCompact Disc Rewritable
- 6DVD-R/RWDigital Versatile Disc-Read/Rewritable
- 7BD-RBLu-Ray Disc Rewritable
- 8BD-REBLu-Ray Disc Recordable Erasable
- 9What are Solid State Drives (SSD’s)?No moving parts and non-volatile memory
Much faster read/write ability
Produced less heat and less susceptible to damage
More expensive and Finite number of writes - 10What is a driver?A piece of software that helps the OS to “speak” to the hardware
- 11What is an M.2 card?Smaller form factor of storage device.
Inserts into the expansion bus
Common cards have an “M” or “B” key (can have A/E keys that serve other functions)
MOBO can support one or both depending - 12What bus does the “M” key on an M.2 use on the MOBO?Uses max of PCIe X 4
- 13What bus does the “B” key on an M.2 card use?Can use the PCIe X 2
- 14What can an M.2 card support?Bluetooth, NFC, GPS, WiFi, PCIe and SATA connections
- 15What are M.2 cards also labeled with?Their size
- 16What is a Hard Disk Drive (HDD)?Storage Device with spinning drive and magnetic storage
Random access
Potential to break
- 17How does the speed work for HDDs?Measured in revolutions per minute (rpm) which refers to the rotation of its disk
The faster or larger the revolutions, the less latency there is which equals better performance - 1815,000rpms = how many milliseconds (ms)of latency?2
- 1910,000rpms=how many ms of latency?3
- 207,200rpms=how many ms of latency?4.16
- 215,400rpms = how many ms of latency?5.55
- 22What typically uses the HDDs with the highest rpms?Places like data centers
- 23What typically uses HDDs with the lowest rpms?Your desktops
- 24What do HDDs connect to on the MOBOSATA and PATA interfaces
- 25What are Hybrid drives?Combines the characteristics of Solid state drives and Hard disk drives
- 26What are SSHDs?Solid State Hybrid Drives
Has a spinning drive and SSD in on device
The HHD part is used for storage while the SSD part is used as cache
Allows to write quickly and store while able to multitask - 27What are USB Flash Drives?Extremely portable, compact storage device that is non-volatile
Has limited number of writes (storage)
Not good for permanent storage by of its size and easy to lose - 28What does non-volatile memory mean?Means that you can disconnect the device without having to power it down and it can still retain the data on it.
- 29What is an NVMe?Non-volatile Memory Express
Supports SATA and PCIe
Can fit into M.2 slots
Can be used as a bootable source if MOBO supports it - 30What is RAID?Redundant Array of Independent/Inexpensive Disks
A backup system for when drives fail that share info across multiple drives
