Thanks to the fact that the 3.5” hard drive does not need to be secured in a carrier, no screwdriver is required, and the installation and removal can be done twice as fast. A 5.25” bay is needed. It supports SATA hard drives with speeds of SATA I, II, and III. The housing of the exchange frame is made almost entirely of aluminum, with only the front and rear panels made of hard plastic. Aluminum is very stable and lightweight, especially known for its excellent thermal conductivity. To protect the hard drive from unauthorized access, the hard drive slot can be locked. An LED indicates operation and access, but there is no alarm for hard drive failures or similar issues. Those who appreciate silence will find this beneficial. The exchange frame supports all 3.5”/2.5” SATA/SAS 1.5/3.0/6.0 Gbit/s hard drives (1” high) and is installed in a standard 5.25” slot. The special aluminum housing ensures better cooling and supports hot swapping. The lock protects against unauthorized access. The fanless design allows for silent operation. A 12V power connection is available for an additional fan if needed.
