Model No: ASSY 654540-001 REV B External Interface: SATA(Max. SATA3.0 6Gbps/Sec) Compatible Drive Type:2.5" SATA or SAS HDD SSD Device fit: 3.5" SATA hard hot-swappable drive bay Structure: SECC(Steel Electrogalvanized Cold-rolled Coil) Steel body Dimension:147*101*12mm Note: This adapter can convert any 2.5" SAS/SATA/SSD drive to 3.5" form factor. However, for 2.5" SAS drives, this adapter will change dual port to single port. This is fine for most applications. But if your application requires dual port, this adapter will not work for you.
