Pros Very Fast, not a single problem with using it for over 3 years
Cons Not available yet in 1TB size (3/2/2008)
Summary I have 2 of 250GB units that I have been using for over 3 years. I found this product to be one of the best NAS products on a market. Straight forward, reliable, fast, easy to use. As a busy professional I don't have a lot of time to fix the problems, I tried multiple NAS products from different manufactures and non of them pass. I only wanted to change to something larger then 250GB but I'll wait for Ximeta release of 1TB and just go with that.
Pros Super High performance, Multiple machine access, Don't need to store nearby
Cons Weak OSX support, partitioning support is minimal
Summary I've read a lot of very negative reviews of this drive from people who have simply not understood what this drive is about, so this is my attempt to write a counter opinion.
Firstly, do not buy this drive if you're looking for a USB drive. It will work fine, but you'll be wasting money buying things you don't need. Also, you'd be better getting a drive which is designed to work well in a USB setting (tidy power cord, etc).
Secondly, and less well understood, this drive is NOT a NAS drive. You plug this in and access it over the network, and you plug a NAS drive in and access it over the network, so what's the difference? The difference is where the smarts are kept. In a NAS drive, the logic is put on the drive which gives low performances but really high compatibility. Also, fancy features (e.g. iTunes server) are inconceivable on this drive but pretty commonplace in NAS drives.
What this drive does is shift all the fancy I/O logic from the drive to your computer. As a result there are heaps of things you can do with this drive you'd never be able to with a NAS drive (like have decent performance, or format it with a different partition type). The downside is that you're much more dependent on driver quality than you would be if you were using a NAS drive.
If you're using windows, you're pretty much sweet - the drivers are stable and have been for years. If you're using linux, you're also pretty well off - the drivers are new and a little rough, but they work. If you're using Mac OS, things aren't quite so good with only one machine able to write at once - though any number of machines can read. Also, people in a heterogeneous environment should probably steer clear. There is no filesystem in existance which supports multiple access and is available for more than one OS. Also, you can't create partitions to work around this since the driver doesn't support partitions.
Having said that, this drive will allow you to put all your stuff on an external disk, access it from any computer and access it so fast you can hardly tell it isn't built in. Just perfect for expanding the capacity of a laptop, for sharing music, or whatever.
The drive claims to not use IP networking. Assuming this isn't just marketing speak, I guess it means it is using ethernet routing which means cheaper wireless networks might have trouble with it - personally my (pretty cheap) netgear wireless had no trouble, though I usually use wired for performance.
Users coming from an enterprise background will recognise the strong similarity between this drive and a SAN. That comparison is fair, with the drive effectively acting as a SAN but missing most of the features you'd expect in an enterprise product. Think of it as an AoE (ATA over Ethernet) SAN without the pricetag, performance, hotswap, and multiple partition support and you're pretty much dead on. The latest drivers provide remote SMART capability, so you will at least know to do a backup before the drive fails.
Final comment, this is cheaper than most NAS drives, gives ten times their performance on short reads, and works well with linux and windows. If that's what you're looking for, you're going to be very happy. If you're looking for a NAS to share documents in your macintosh workgroup, you're going to be very disappointed.
Pros Cheap and low power
Cons Does not work through routers, does not permit read-write access for more than one computer, the "Superior Technology" simply emulates SCSI drive and requires OS-specific driver installation on each client computer.
Summary Those who wrote positive reports probably have only one computer and do not share files. I bought it to replace old Linux box with Samba server that served me for more than 10 years, hoping to get lower power consumption. Yes, I was able to install this on WinXP and Win7 (with software from Ximeta site), and yes, the disk with NTFS was instantly available. Encourages, I rushed to install it on other machines and (surprise!) the management utility found the drive and told that it is shared in read/write mode already, thus another computer can at most only read the content, sharing it as readonly... If I knew it at purchase time, I would never buy it - what is the use of a shared storage which cannot be shared freely to pass large files between computers? It it is a pity that it is not IP-based and cannot be a true file server, that it does not work when wired and wireless networks are on different subnets (as some home routers implement), and that you have to go through installation of a proprietary driver on every machine (your guests will not have instant access to the photos you want to share!). But the true disadvantage is the inability to share read/write access for more than one computer, which is the opposite to what can be inferred from the picture on the box.
The recommendation - buy if you have one computer - otherwise find something less "superior" which supports NAS or SMB protocol and operates through TCP-IP.
Pros Fast in network mode compared to others.
Cons Does not support wireless connections. Does not support windows sleep mode properly. No real support just excuses.
Summary When it works it works fine and fast but can you count on it? I have even tried to share this drive (which means you need to leave a PC on all the time) and the result is unpredictable. You can only use this drive on a wired network. You cannot use the sleep mode on your wired PC. So don’t count on this drive to be used as your TV recording memory. I was expecting this drive to be a stand-alone file server for all my PC's, be my storage system for recorded material. Unfortunately, the wireless mode is not well supported (it does work on wireless B and is flaky on wireless G), the sleep mode renders the connection to the drive unstable so even sharing is not possible unless sleep mode is not used and if you leave your PC on all the time. If you dedicate this drive to a PC and share it, you better use the USB port. You still need to leave your PC on but everything else works fine. When comparing this drive to other drive, please compare it with USB drives and forget about its network capabilities. Support for this drive is almost inexistent and limited to being told it’s a special protocol. Who cares if the protocol does not do want you expect.Updated
This is to rectify that this drive does not support wirelles B.
