Summary: The product works ok; it was not easy to configure. Once in a while, all configurations were gone!!! Data was not affected. Mine went on reboot cycles indefinite when 2yrs up. We started up a device when needed usually about once/month.
Summary: I bought a TS-S402 back in May, and since then I've burned up two drives. I have them mirrored, and when one burns up I have to copy ALL the data off the drive, then replace the bad drive. The NAS will not rebuild the new drive on its own.
Summary: This unit is whisper quiet with a good bit of capability under the hood. It's gigabit NIC port allows for speedy transfers from other systems with gb ports configured. I have mine configured with dual Western Digital 1.0 TB SATA HDD's and it works fine.
