How does Double Data Rate Random Access Memory (DDR RAM) achieve higher data rates over ordinary Dynamic RAM (DRAM)? (Select all that apply) Select one or more: A. DDR uses NAND flash (in contrast to NOR flash used in DRAM) B. DDR uses higher clock rate on the bus to increase the transfer rate. C. DDR has internal cache to speedup the process D. DDR uses a buffering scheme E. The data transfer is synchronized to both the rising and falling edge of the clock, rather than just the rising edge.

Creating a RAID array is a way for producing live backups of physical hard drives; however, doing so will lower the amount of available capacity on the physical hard drive. Alternatively, would you like to have backup at the cost of half of your available disc space? The ideal RAID configuration for a home computer system with frequent power outages that may result in hard disc failures is determined by the frequency of power outages.
1. Raid Consider two implementations. Implementation A uses Raid Level 1 and B uses Raid Level 5. B places 5 disk drives into each parity group. How much disk space will be needed for each implementation if the intent is to provide 2 Terabytes of disk space to the application? What will the write time be for updating a block? Assume 10 millisecond read times and 10 millisecond write times on a disk drive.
These cylinder requests come in to a disk driver. The disk driver code can only buffer five requests at once. Requests for tracks 13, 21, 11, 80, and 65 come in. The order of the requests be processed are 13, 21, 11, 80, and 65. This indicates the seek algorithm used is: C-SCAN RAID FIFO SSF
Creating a RAID array is a technique for generating live backups of physical hard drives, although doing so will reduce the available capacity of the hard drive. Alternatively, would you want to have backup at the expense of half your available disc space? When it comes to a home computer system that has regular power outages that might result in hard disc failures, which form of RAID is the best choice?

A certain moving arm disk storage, with one head, has the following specifications. Number of tracks/recording surface = 200 Disk rotation speed = 2400 rpm Track storage capacity = 62,500 bits The average latency of this device is P msec and the data transfer rate is Q bits/sec. Write the value of P and Q.
Standard rotating magnetic disks are given preferential treatment in RAID systems because of this bias. RAID storage for SSDs is not required, however it is recommended. Otherwise, does this make SSD storage for the enterprise a little bit more affordable? Is it required to have redundant drives, and if so, do they have to be solid-state disks (SSD)?

Facts: What is RAID? RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDS) to protect data in the case of a drive failure. There are different RAID levels, however, and not all have the goal of providing redundancy. How RAID works RAID works by placing data on multiple disks and allowing input/output (1/0) operations to overlap in a balanced way, improving performance. Because using multiple disks increases the mean time between failures, storing data redundantly also increases fault tolerance. RAID arrays appear to the operating system (OS) as a single logical drive. RAID employs the techniques of disk mirroring or disk striping. Mirroring will copy identical data onto more than one drive. Striping partitions e help spread data over multiple disk drives. Each drive's storage space is divided into units ranging from a sector of 512 bytes up to several megabytes. The stripes of all the disks…
In a RAID 5 configuration of four 1TB solid state disks, the total available storage is ___ TB. Enter the number in TB only, e.g., 7.
Define the RAID levels 0, 1, and 5. If we have four 200GB disks what will be the capacity for each of thesesystems.
