Exploring Future Storage Technologies

A Solid State Drive (SSD) stores data using which of the following technologies?

• Magnetic platters that spin at high speeds

• Flash memory chips that retain data without power

• Optical laser technology to read and write data

• Electromechanical actuator arms to access data

Which of the following best describes the difference between a full backup and an incremental backup strategy?

• A full backup copies only changed files, while an incremental backup copies all files

• A full backup copies all data every time, while an incremental backup copies only data changed since the last backup

• A full backup is performed weekly, while an incremental backup is performed monthly

• A full backup stores data in the cloud, while an incremental backup stores data locally

Which of the following emerging storage technologies uses the resistance of materials to store data, offering faster write speeds and greater endurance than traditional NAND flash?

• Holographic storage

• Resistive RAM (ReRAM)

• Magnetic tape storage

• Optical disc storage

Which metric is commonly used to measure the performance of a storage device in terms of how quickly it can read or write data?

• Latency in milliseconds only

• Sequential and random read/write speeds measured in MB/s or GB/s

• The number of platters inside the drive

• The physical size of the storage device in inches

An SSD uses the NVMe interface instead of SATA. What is the primary advantage of NVMe over SATA for SSDs?

• NVMe drives are physically larger, allowing more storage capacity

• NVMe drives consume significantly more power, making them more reliable

• NVMe drives communicate directly through the PCIe bus, resulting in significantly higher data transfer speeds

• NVMe drives use magnetic storage, making them more durable

In the context of SSDs, what does the term "wear leveling" refer to?

• A technique that physically balances the weight of the SSD inside a device

• A method that distributes write and erase cycles evenly across all memory cells to extend the lifespan of the SSD

• A process that reduces the physical size of the SSD over time

• A cooling mechanism that prevents the SSD from overheating

Which of the following correctly describes the 3-2-1 backup strategy?

• Keep 3 backups on 2 different media types, with 1 backup stored offsite

• Perform 3 full backups, 2 incremental backups, and 1 differential backup per week

• Store 3 copies of data on 2 cloud services, with 1 local copy

• Backup data 3 times a day, 2 times a week, and 1 time a month

DNA data storage is considered an emerging technology. Which of the following best describes why DNA storage is considered advantageous for long-term data archiving?

• DNA storage devices are inexpensive and easy to manufacture at scale today

• DNA can store massive amounts of data in an extremely small physical space and can remain stable for thousands of years

• DNA storage allows real-time read and write access comparable to SSDs

• DNA storage uses electrical signals to encode data, making it compatible with existing hardware

Which of the following factors most directly affects the random read/write performance of an SSD compared to a Hard Disk Drive (HDD)?

• The SSD has no moving mechanical parts, allowing it to access any data location almost instantly

• The SSD uses magnetic platters that spin faster than those in an HDD

• The SSD has a larger cache memory than an HDD

• The SSD uses a wider data bus than an HDD

IOPS (Input/Output Operations Per Second) is a key performance metric for storage devices. If an SSD has an IOPS rating of 100,000 and an HDD has an IOPS rating of 200, approximately how many times faster is the SSD at handling random operations compared to the HDD?

• 50 times faster

• 200 times faster

• 500 times faster

• 1000 times faster
