Hard Disks
Two 2.5 inch SATA hard drives (HDD) or solid state drives (SSD) are supported. These
drives can be configured as standard hard drives or as a RAID array. The SATA interface
can support data transfer rates up to 6.0 Gb/s and supports AHCI and Hot Swapping of
hard drives.
The HDDs can easily be accessed by removing a panel on the left side of the unit. HDDs
can be installed or removed in seconds by removing one screw. A carrying tray (two of
which are supplied with the 680) fits onto a new drive without tools. The drive can now
easily be slid into the drive bay. In a RAID 1 configuration a drive can be hot swapped,
removed, or inserted with the power on (see section on RAID setup).

Zero Bezel Touch Screen
The 680PTC unit uses a Multi-Touch Projected Capacitive technology touch screen
(PCT). The PCT touch screen has no known failure mode-- it does not wear out. This
screen is made with tempered glass and does not reduce the brightness of the LCD panel.
When operating in a very high use environment PCT is the recommended touch screen
technology. The PCT touch screen will work with most gloves and stylus designed to
work with tablet computers. The screen has a smooth glass surface that is reflective.
The 680TFR uses a five-wire touch screen rated at 35 million touches per point. The
resistive technology is very responsive and is the traditional choice for a hospitality POS
system. The screen has an anti-reflective plastic film surface.
Both screens are fully spill proof, dust proof and can be cleared with and standard glass
cleaner. The zero bezel, sometimes called true flat, design allow for this plus easy
cleaning. The 680 touch screen was designed to easily be changed, normally in less than
two minutes. Depending on operating environment and usage, both the Resistive and
PCT touch screens have strengths and weaknesses. J2 offers both touch screen
technologies on the 680.
