Very well built external enclosure with great flexibility By BrianLy The TowerRAID arrived in a pretty big box so I was expecting something a lot bulkier than most enclosures. It turned out to be sleeker than I had expected but has a pretty heavy build quality. The case is along the lines of a Mini PC case. Installation of the drives was simple and unspectacular but the bulky cover was a little difficult to get back on. Once powered on I found the fan to be very quiet compared to other single drive enclosures I have. There is a bright blue LED at the back which I found to be annoying. It is probably only a matter of opening the case and disconnecting, but I haven't gotten around to this yet. I chose to install the supplied PCI-Express card rather than use my existing eSATA connection. I understand that this enables some sort of daisy chain configuration of these enclosures in the future.Installation of the drivers and configuration software under Vista x64 was successful but I did find a subsequent update on Windows Update which I promptly installed. The configuration utility is written in an older version of Java which forces desktop composition to be turned off when it is running. So expect some screen flicker as a result of this. In disk manager all drives installed present themselves individually until you turn them into a RAID set using the utility. This enables some interesting uses. I have 2 drives configured as a mirrored array for backup purposes, with another standalone drive for scratch/temp/junk space.Since my initial installation, I rebuilt my machine from scratch with Windows 7 x64. I disconnected the array before installation and reconnected it after Windows 7 was installed. It installed a driver from Windows update for the supplied PCI-X card and I was up and running. Since the RAID etc was configured I did not need to install any of the management software.I would recommend this product to technical professionals and advanced users. It is not what I would consider a consumer product but it will work in that situation of setup properly for the end user. 13 of 13 people found the following review helpful. Excellent product! By Zulfiqar Ali Naushad I had serious issues with an ICYDOCK product ICY DOCK MB561US-4S - 4 Bay 3.5" SATA to USB & eSATA Removable Aluminum Hard Drive enclosure with 80 x 80mm Detachable Fan - Pearl White with the drives overheating. Decided to go with the Sans Digital device.The TR4M is bigger and hence has more ventilation as compared to the ICYDOCK product. Drive temperatures are being reported as a whopping 15 deg C lower than the ICYDOCK product.I also like the plethora of LED's in the front to show the status of the drives and the TR4M. Using it with my HP Mediasmart Windows Home Server and couldn't be happier!One thing is that I wish it came with Drive sleds, and that it didn't use a cheesy blue LED rear exhaust fan. But other than that it's a stellar product!Highly recommended product. 11 of 11 people found the following review helpful. low cost, fast, mass storage By D. D. Reuter I have 6 of these units running on Vista32Pro and Win7Pro-64 PCs. Units have 4 matching WD 1TB Green drives or WD 2TB Green drives installed using striped RAID (single logical drive per box). All units run cool and quiet -- quiet enough to sit right next to the units and work all day without annoying fan/drive noise. Multi TB data transfers between units on the same PC average between 80-90 MBps (smaller transfers peak at 120 MBps due to RAM cache). TB data transfers across a 1 Gbps network average 58-65 MBps depending on network traffic. RAID 5 (redundancy within one box) slows writing speeds to 25-30 MBps. If speed matters and redundancy is essential (as it should be), best to use simple striped RAID with matching drives, get redundancy by using multiple boxes and use folder syncing software -- I use AllWay Sync (works like
