摘要： An operation method includes measuring figure of merit (FoM) values for a first group of presets having different preset types, based on equalized signals output from a transmission equalizer included in an external device adjusted based on the first group, identifying a preset type of a first preset corresponding to first FoM value which is a greatest value from among the FoM values for the first group, measuring FoM values for a second group of presets having the identified preset type, based on equalized signals output from the transmission equalizer adjusted based on the second group, determining a second preset corresponding to second FoM value which is a greatest value from among the first FoM value and the FoM values for the second group, and transmitting an equalizing setup request that controls the transmission equalizer to the external device, based on the determined second preset.

摘要： A storage device includes a nonvolatile memory device and a storage controller. The storage controller accesses the nonvolatile memory device based on a request of an external host device. The storage controller sends a signal to the external host device, based a throughput of accessing the nonvolatile memory device being within a specific range.

摘要： A redundant array of independent disks (RAID) storage device including; a memory device including first memory devices configured to store at least one of data chunks and corresponding parity (data chunks/parity) and a second memory device configured to serve as a spare memory region, and a RAID controller including a RAID internal memory configured to store a count table and configured to control performing of a rebuild operation in response to a command received from a host, wherein upon identification of a failed first memory device, the RAID controller accesses used regions of non-failed first memory devices based on the count table and rebuilds data of the failed first memory device using the second memory device.
