How to find linux device name for path and check if it is ssd

ssd.scala

import java.io.File
import java.nio.file.{Files, Path}
import scala.io.Source


def deviceName(path: Path): String = {
  val absPath = path.toAbsolutePath
  val fsName = Files.getFileStore(absPath).name()
  val fsPath = absPath.getRoot.resolve(fsName).toRealPath()
  fsPath.getFileName.toString
}

def isSsd(devName: String): Boolean = {
  import scala.collection.JavaConverters._
  val sysinfo = new File("/").toPath.getRoot.resolve("sys").resolve("block")
  val d = Files.newDirectoryStream(sysinfo).asScala
    .filter(d => d.getFileName.startsWith(devName))
    .toSeq
    .maxBy(_.toString.length)
  val path = d.resolve("queue").resolve("rotational")
  val s = Source.fromFile(path.toFile)
  try {
    s.getLines().mkString.trim == "0"
  } finally s.close()
}
