Bought as part of our work to house VMware virtualized machines, we had a performance concern but we finally discovered that it was due to poor setting. Since we changed the iSCSI configuration, we get top-flight performance, comply with the tests we had read and our expectations. We must of course involve a fast disk drives 7200 rev / min (for example, Seagate Barracuda 7200.14 ST2000DM001). Preferably, it is necessary to 5 identical hard drives. We must therefore check the availability of these discs (some retailers / sellers have a single hard drive in stock, and you still will add 5 discs in your shopping cart!). I do not give details about the device, you can find them on the manufacturer's website. Just know that it is guaranteed for 3 years (two contradictory information is given on the Amazon site at the time of writing).
In summary, if your sole intention is to make data storage, go your way, you will definitely find cheaper NAS. But if you're looking for performance, I recommend this device.
