Q1Domain Verified
In the context of SSDs, what is the primary function of the Flash Translation Layer (FTL)?
To manage the physical wear leveling of NAND flash cells across the entire drive.
To perform data encryption and decryption for enhanced security.
To abstract the physical block structure of NAND flash memory into a logical block addressing (LBA) scheme for the host.
To optimize read/write operations by caching frequently accessed data in DRAM.
Q2Domain Verified
When considering HDD platter technology, what is the significance of increasing areal density beyond a certain point, particularly concerning the magnetic coercivity required?
Increased areal density directly correlates with reduced track pitch, making servo control less critical.
Higher areal density allows for larger magnetic domains, simplifying the read head design.
Extremely high areal density can lead to superparamagnetic limit issues, requiring materials with higher coercivity to maintain data stability.
Higher areal density necessitates lower coercivity to achieve faster magnetic switching speeds.
Q3Domain Verified
In a RAID 0 configuration, what is the theoretical maximum performance gain in terms of read/write throughput compared to a single drive, assuming ideal conditions?
50%
It is not possible to quantify a theoretical gain without knowing drive specifications.
