12 Questions
What is the primary purpose of using volatile RAM-based SSDs?
To enable fast data access when applications require it
How does volatile RAM-based SSDs store data during data access?
In the DRAM
What is the main characteristic of NAND-based SSDs compared to volatile RAM-based SSDs?
They allow only a finite number of writes over the device lifetime
Which type of SSD is widely used today in mobile devices, digital cameras, and MP3 players?
NAND-based SSDs
What is the primary function of DRAM in an SSD?
To increase the read/write performance
What is the purpose of the wear leveling function in SSD firmware?
To spread writes across different chips to use them at the same rate
How does the trim function in SSD firmware affect unallocated space?
It wipes the unallocated space of the device
Which SSD host interface is commonly used based on different performance requirements?
Peripheral Component Interconnect Express (PCIe)
What is the main advantage of a Solid-State Drive (SSD) over a Hard Disk Drive (HDD)?
SSDs use NAND flash memory chips and have no moving parts, making them faster than HDDs
How does the structure of a 4K sector differ from that of a 512-byte sector?
4K sectors remove redundant header areas between sectors and use identification and synchronization characters for ECC
In disk capacity calculation, what does the CHS addressing method specify for each physical block of data on a hard disk?
The cylinder, head, and sector of the data block
What is the total capacity of a disk drive with 8,192 cylinders, 64 heads, and 56 sectors per track, assuming each sector has 1KB?
$2,821,220,864$ bytes
