Hot Swappable Hard Drives DriveStation Duo's hot swap feature allows a user to replace a hard drive in the event of failure without powering down the device. Simply remove the defective drive, insert the new drive and the data rebuilds while still being available to clients on the network with zero downtime. Buffalo Tools Buffalo Tools is a feature-rich suite of optional software included on the Buffalo DriveStation. Any or all of the following components of Buffalo Tools may be installed on Windows PCs: Buffalo's Backup Utility, TurboPC, eco Manager, SecureLock RAID 0 DriveStation Duo provides users the flexibility to easily maximize capacity or protect their data using RAID redundancy. RAID 0 combines all drives into a single array offering maximum storage capacity with no redundancy. RAID 1 RAID 1 offers maximum redundancy by mirroring both drives. Data is automatically duplicated, so that if one drive fails, the data is kept safe on the other. Review: Great for people who need reliability and don't want a NAS - What this is - an external USB hard drive, not a network drive (NAS). The main reason to buy - reliability. There are 2 identical hard drives inside that record the same data, so that if one fails then the other still has your data. That's what RAID technology gives you, among other things. 20% of mechanical hard drives will fail before 4 years. Compare to NAS - NAS is basically a file server on the local network. It's accessible to multiple computers and should be turned on all the time. On the other hand, this Buffalo DriveStation attaches to a single computer via USB 3 port. It turns off automatically when the computer turns off. Both use RAID technology with multiple hard drives. Compare to SSD - People think SSD is more reliable because there are no mechanical moving parts, but when left unplugged and under hot weather, the electrical charge can leak out, causing data lost. Hard drive is actually better for archival purpose, i.e., years of storage. SSD is only more reliable for shorter duration, such as less than a year. Compare to a single hard drive with cloud back up - Cloud back up is very expensive, although very reliable, because the cloud is still there if the hard drive is burned out or stolen. Transfering several TB of data to cloud storage will take days even on fast broad band. This option is only viable for small amount of data, such as less than 200GB. Clouds are also prone to computer hacks, so don't put anything there that you don't want the whole world to see. Installation - plug-and-play just like any external disk drives. Works great on my Windows 10. The utility on included disk can configure different RAID modes if needed. There are instructions for Mac, although I haven't tried. One wierd thing about the utility is that no application window shows up when it runs. To launch, right click on the Buffalo RAID utility icon in the system tray instead. Hardware - fan is nearly silent on idle and can spin up much louder on start up or when the drives get hot. The front plate can pop-out to show meanings of different color and blinking combinations of the 3 front LEDs. There's a physical off switch, which I like because hard drives last longer when they are not used frequently, and no hackers or viruses can affect a power-off hard drive. Review: Easy to Use, Affordable - Easy to use, copied over contents from a PC we're obsoleting. Lots of space. Will be primary storage for replacement PC. Thought it was a NAS (my bad), but it works so I can't complain. ## Features - Pre-tested NAS-grade hard drives included – with RAID pre-configured - Premium desktop attached storage (DAS): ideal for creative professionals, small office users, server backup and consumers - USB 3.2 Gen 1 offers universal connectivity for PC and Mac computers and storage servers - Made in Japan - TAA compliant - 4 TB – 2 drives included - ships in RAID 1 = 2 TB usable capacity - 3 year wnty with 24/7 North American-based support - PC Compatible plug-and-play.
