What are the advantages of Solid State Drives (SSDs)?
- Faster performance
- More durable
- Silent operation
- Lower power consumption
SSDs outperform HDDs in speed and durability while being more energy-efficient.
What is a major disadvantage of Solid State Drives (SSDs)?
Higher cost per TB than HDDs
The cost of SSD storage is generally higher compared to HDDs, especially for large capacities.
What does TBW stand for in relation to SSDs?
Terabytes Written
TBW indicates the total amount of data that can be written to an SSD over its lifespan.
What is the technology behind M.2 Drives?
Compact form factor for internal mounting
M.2 drives are designed for high-speed storage in a small footprint.
What is the performance difference between SATA and NVMe M.2 Drives?
NVMe M.2 can achieve 5-7GB/s vs 550MB/s for SATA
NVMe offers significantly higher data transfer speeds compared to SATA.
What are the typical capacities of USB Flash Drives?
8GB to 1TB
USB Flash Drives come in various storage sizes, suitable for different needs.
What are the types of optical media?
- CD-ROM
- DVD
- Blu-ray
Optical media types vary in capacity and usage, with CDs being the smallest and Blu-rays the largest.
What is the RAID level that focuses on performance without redundancy?
RAID 0
RAID 0 offers improved performance through striping but does not provide data redundancy.
What is the maximum partition size for MBR?
Up to 2TB
MBR has limitations on partition size and the number of partitions.
What file systems are commonly used in Windows?
- NTFS
- FAT32
- exFAT
These file systems offer varying features and compatibility for Windows environments.
True or False: SSDs have unlimited write cycles.
False
SSDs have a finite number of write cycles, which can affect their longevity.
What does the 3-2-1 backup strategy entail?
- 3 copies of data
- 2 different media
- 1 offsite copy
This strategy helps ensure data safety and recovery in case of failure.
What is the speed of USB 3.2 Gen 2x2?
Up to 20Gbps
USB 3.2 Gen 2x2 offers higher transfer speeds compared to previous USB standards.
What are the common issues associated with Hard Disk Drives (HDDs)?
- Bad sectors
- Mechanical failure
- Corrupted partition table
These issues can significantly affect the performance and reliability of HDDs.
