library(dplyr)

ssd_speed %>%
  count(form_factor)

ssd_speed %>%
  filter(form_factor != "mSATA") %>%
  ggplot(aes(x = read, y = write, color = form_factor)) +
  geom_point() +
  labs(
    title = "Average read vs. write speed of SSDs",
    x = "Read speed (MB/s)",
    y = "Write speed (MB/s)"
  ) +
  facet_wrap(~form_factor, ncol = 1, scales = "free") +
  guides(color = FALSE)
