Manufacturer description
The StarTech.com HSB100SATBK turns any free 5.25in bay into a front-accessible hot-swap dock for a single 3.5in SATA hard drive, which makes it a practical fit for retro builds and test benches where you swap disks constantly. The trayless design is the point: you slide a bare drive straight into the backplane with no caddy, no screws, and no reason to pull the side panel off your chassis. Internal rubber shock absorbers cushion the drive during insertion and operation, and the bay is rated for 50,000+ insertions, so this is not a mechanism you expect to wear out after a season of disk…

Frequently Asked Questions
Will this fit my case?
It needs one free front-accessible 5.25in bay, the size older optical drives used. Full-tower and older ATX cases usually have them; most current mid-towers do not.
Do I need a tray or caddy for the hard drive?
No. The HSB100SATBK is trayless, so a bare 3.5in SATA drive slides directly into the internal SATA backplane. No mounting hardware or screws per drive.
How many drives does it hold?
One 3.5in SATA hard drive per bay. If you swap between several disks, you use the same bay and change the drive, which is what the 50,000+ insertion rating is for.
Can I lock a drive in place?
Yes, the drive bay is lockable, so a drive cannot be pulled out mid-operation or removed from a shared machine without the key.
Is true hot-swapping supported?
The backplane is built for it, but hot-swap also depends on your SATA controller running in AHCI mode. Check your motherboard BIOS settings and the product listing for controller requirements.
