SK Hynix Gold S31 SATA 500GB 2.5" SATA SSD

SK Hynix Gold S31 SATA 500GB 2.5" SATA solid state drive on the SATA III interface. Standard 2.5-inch 7mm SATA drive for desktops and laptops. Seller note: Samsung, Western Digital/SanDisk, Crucial (Micron) and SK Hynix build their own NAND flash, while other brands pair purchased flash with third-party controllers such as Phison — check the exact model revision, since manufacturers sometimes change controller or NAND mid-production. Always confirm drive health (SMART power-on hours and written terabytes) before listing a used drive.
