As notebooks, tablets and phones become more prevalent in schools, look for desktop computers to start learning some of their tricks and better fit into the educational landscape. For instance, Acer’s Revo One makes a virtue of being small, powerful and – above all – stationary.
Unlike other desktop PCs, the Revo One is tiny compared to the typical desktop or tower case. While Apple’s Mac Mini and HP’s Pavilion Mini are a little smaller, the Revo One’s 6.1- by 4.2- by 4.2-inches dimensions mean that it will fit where other computers can’t. It can be set up on a shelf or even in a desk drawer.
There’s a power switch in the back as well as lights on top to show that it’s turned on and its drives are active. Still, the flagship Revo One RL85 model that I looked at packs the power of a full-size system with a dual-core Core i5 processor that runs at between 2.2- and 2.7GHz. The processor has 3MB of its own cache and my test machine included a generous 8GB of RAM and a 1TB hard drive for $580. There are models more appropriate to schools that start at $250 for a Celeron-powered system with 2GB of RAM and 60GB of solid state storage, which can give Chrome machines a run for the money.
A bonus is that as small as the Revo One is, there’s room for two more 2.5-inch hard drives inside. Pull the cover off of the chassis and the drives snap right in. I added 500- and 750GB hard drives, which I set up as a RAID 5 array that can recover lost data from a drive failure. Alternatively, the system can also be configured to run as a simple set of disks for maximum capacity or RAID 1 mirroring for storing data that can’t be lost.
It may be small, but the Revo One has a Trusted Platform Module inside as well as an excellent assortment of ports that make it a good PC to build a computer lab around. In addition to a pair of USB 2.0 ports, there are two connections for faster USB 3.0 accessories. It can connect via its wired LAN, 802.11n WiFi and Bluetooth 4.0.
The system’s video is handled by Intel’s HD Graphics 5500 graphics accelerator but without any dedicated video memory; it borrows up to 3.6GB of RAM from the system, which makes having 8GB of RAM a good idea. It has both an HDMI and a mini Displayport output for connecting to a projector or display, so it can even be used to support a pair of monitors at once. It has an audio jack and an SD card slot.
Because of its limited size, the Revo One does without two things. There’s no DVD drive, but you’ll hardly miss it. Plus, you can’t add a graphics or other specialty card to the system. It’s a small price to pay for such a small system.
While the system comes with matching a wireless mini-keyboard and mouse, the Revo One does a cool trick that roaming teachers will appreciate. With the free Revo Suite software for Androids, the system can be controlled from a phone or tablet, even if you’re on the other side of the room. It needs to be on the same network and have Bluetooth turned on to connect. The software is a little clunky and doesn’t show what’s on the system’s screen, but if the teacher’s screen is projected for the class, she can control what it shows from anywhere in the room.
Unlike the latest ultra-mobile devices, the Revo One has a cooling fan. It is quiet and the unit never got more than warm in over a month of daily use ina variety of tasks from server duties to running math and science simulations. When it is being used the system consumes 22.5-watts of power, less than the power draw of a light bulb. In sleep mode, it uses 10.5-watts, but can quickly wake up after hitting the keyboard. This leads to an estimated annual cost of operation of just $2.50, assuming it’s used for 10 hours a day during the school year and off the rest of the time; I used the national average of 12 cents per kilowatt-hour in my calculations.
Despite this lower power use, the Revo One has the power for a variety of tasks from video editing to teaching with an interactive whiteboard. It scored a 1,689.2 on PassMark’s PerformanceTest 8 benchmark tests that stress every part of a computer. That puts it at roughly three-times the output of most school computers.
Acer proves that good things really do come in small packages. In fact, the Revo One makes most desktop computers obsolete with its mix of size, price and performance.
