Western Digital has enhanced HDD capacity to 32TB with its new SMR drives, which provide higher density using advanced recording techniques, but at slower rewrite speeds.
SMR drives optimize data storage by overlapping tracks, making them efficient for sequential writes while limiting the ability to rewrite data quickly compared to traditional drives.
Western Digital's ePMR technology enables fine-tuned writing on HDDs, increasing data density without affecting the proximity of existing bits, a challenge in high-density recording.
Despite improved density and performance, HDDs still lag behind SSDs in speed, offering lower costs per gigabyte, making them a cost-effective storage solution when speed isn't critical.
