Lian Li EX-503 HDD Hot Swap RAID Case - Black [EX-503]

Lian Li is known for its extremely high-quality, hand-crafted aluminum body with a contemporary design and functional features. One of these features is SATA hot-swap, whereby a corresponding drive can be replaced quickly and hard drives to removable storage are virtually. After the fixed hot-swap drive cages and retrofitting internal solutions Lian Li is now offering external hard drive enclosure with this technology.

The EX-503 is the successor to the EX-50 and how this provides space for five 3.5-inch SATA drives. Also, the shape corresponding to the predecessor, so that it is a simple elegant aluminum housing. The main difference is in the connections. While the EX-50 can be connected via eSATA only, available with the EX-503 eSATA and USB 3.0.

The EX-503 is designed for five SATA hard drives, which are pushed through a lockable front in the case. Thanks to hot swap the connections for data connection and power supply permanently installed and must be disconnected from the drive - insert enough. In addition to the data connection to the PC is connected to the back of a power supply that is included and ensures the power supply of the box.

There is also a toolbar, which provides different RAID modes to choose from. With the Big mode the drives as a single treatment, with appropriately summed amount of memory. In addition, the EX-503 supports RAID 0, RAID 1, RAID 5 and RAID-10.

With RAID 0 the data is distributed across multiple drives to maximize read and write speed. Should be RAID-1 sets the priority of the security on the other hand, by writing all data stored in parallel and are not lost when a drive have a defect. If the RAID-1 drives are used with different sizes of memory, the memory corresponds to the usable volume of the smaller drive.

The modes of RAID 5 and RAID-10 offers a mix of higher speed, while providing greater security. The solution is also based purely hardware and requires no special drivers or software. The high level of user friendliness is also apparent because the disks for RAID does not have to be reformatted and is even an automatic mirroring in RAID-1 mode as soon as one is exchanged between the two drives.

In order to cool the drive is located on the back of a 140-mm fan that performs quietly with 1,000 U / min is serving. Behind the front prevents a filter that is sucked together with air dust and dirty the interior.
