Logitech HDD/SSD Case Hard Disk Stand [HDD/SSD Stand] Supports 3.5-inch HDDs and 2.5-inch/3.5-inch HDDs. No screws required, simply insert and use. [Full Cover for Peace of Mind] Prevents dust from entering, which can cause poor contact. When inserting a 3.5-inch drive, the entire cover lowers; when inserting a 2.5-inch drive, only the smaller cover lowers, ensuring that dust doesn't accumulate inside even when a 2.5-inch drive is inserted. [For 1-Bay Stands] Recommended for those who frequently swap HDDs or SSDs, such as for replacing them, those who manage data separately by internal hard disk, those who want to freely choose the hard disk manufacturer, and those who want to use leftover internal HDDs as external HDDs after an SSD upgrade. [Power Synchronization] Power-linked with the computer to reduce power consumption by preventing the AC adapter from being left plugged in. - Brand: Logitec - Model: LHR-L1BSTWU3D - Interface: USB 3.0 - Supported HDD Sizes: 3.5-inch, 2.5-inch - Accessories: Power adapter, USB cable - Color: Black Thank you for viewing.
