Pros: Works well. I haven't had any issues with it.

Cons: Fan is cheap and I don't understand why they put a LED on the fan

Overall Review: none as of yet

Pros: It has worked well as an extension of an existing freenas box. I've had 8 3TB WD red drives in it running 24/7 for over a year with no problems.

Cons: The fans are junk. They are both cheap sleeve bearing fans so they are gonna die. The chassis fan is a 120mmx25mm which is easily replaced and I would recommend doing so. The power supply fan is an 80mmx15mm which is a little more difficult to replace and voids the warranty. I would recommend replacing the power supply fan as well. I recommend cougar for the 120mm and silenx for the 80mm since I've had good results from both in the past and both use fairly good hydrodynamic bearings which are quite a bit better than a standard sleeve. You might have to do some splicing of wires to get an aftermarket fan to work.

Overall Review: I would recommend this drive chassis with the caveat that the fans are junk and when you buy the chassis go ahead and at least buy a 120mm case fan and replace the one that is in it since it is so easy. At least that way if the power supply fan goes out the case fan will still keep moving air.

Pros: One of the most affordable 8-disk enclosure for 3.5 '' HD offering SFF-8088 connector.

Cons: Hard disk tray are not good quality one, but OK.

Overall Review: Mini-sas (2) cables (SFF-8088 both ends) that come with the chassis are only 1 meter long.......

Pros: works when it works

Cons: case fan died after 6 months of use. Power supply fan died 8 months later

Overall Review: when the case fan died I didn't want to go through the trouble of going through warranty. Now the power supply fan died after 14 months of use. Convenient for Sans Digital, as the warranty is 1 year and they charge $100 for a replacement power supply that shouldn't cost more than $20.

To anyone who already owns this unit: Be careful not to leave it unattended over extended periods of time. The fans appear to be extremely low quality and your nice little raid security may fall apart if all the drives overheat at the same time. If you use this enclosure, better sit next to it at all times when it's running, so you can catch the fans dying.

This is a product intended to provide data security - put some half-decent parts in it, Sans Digital!

Pros: when they work... they're ok.

Cons: I purchased 4 of these and 2 have failed... on both the failed units, the top 4 slots connected to one side of the controller in the case failed. When they work, their fine, when they don't its hell to get them up again. Frankly i'm looking for a new disk enclosure company...

Pros: I'd like to retract my previous review of the Rosewill RSV-S8. I own two of them and an RSV-S5, all purchased from Newegg, and always gave them a nod of approval not knowing any better. The Sans Digital version beats them all hands-down. The TR8X enclosure is nearly identical to Rosewill's except for slightly different backplane boards and black instead of chrome covers on the drive trays. The big difference is the controller. Both include a rather cheap-looking eSATA port multiplier software RAID 0/1/5/10/JBOD controller, but there is no comparison. The HighPoint RocketRAID-622SD included with the Sans Digital annihilates the Sil-3132-R5 that comes with the Rosewill. First of all, write performance in RAID-5 alone is at least 3-4 times that of the Sil controller, and that alone seals the deal for me. Secondly, while the Sil controller likes to spend days building arrays and checking for redundancy on almost every reboot, the HighPoint will build a 21TiB R5 in about 4 seconds. It takes longer for Windows to do a quick format on the volume than it takes the controller to create it. Third, the controller allows one array to span all 8 drives, whereas the Sil requires one array for each backplane/eSATA connection, or one for every 4 drives (or 5 in the case of the RSV-S5). Last, the Java-based management software that Sil provides is a far cry from the web-based management console of the RocketRAID. It provides email alerts, maintenance tasks, firmware upgrades, and a lot more, and lets you do so from any browser. The controller even has an audible buzzer that's not on the Sil board. If you want the best direct-attached RAID solution for this price range, look no further.

Cons: As with all eSATA devices, the connectors fall out easily, but one can hardly blame Sans Digital for that.

Overall Review: I purchased one of these used for $125 and it's the best money I've ever spent on a storage appliance. I plan to buy several more of the included HighPoint controllers to replace the Sil-3132's on my Rosewill enclosures. These are confirmed to work, and I've also tested the controller with the Mediasonic ProBox. Any eSATA port multiplier device should work.

Pros: Easy installation of drives, fast, reliable, cheapest 8 bay mini-sas enclosure that I could find. Allows for super fast file transfers and fast editing of HD video no problem.

Cons: Blue LED light on the rear fan is a bit obnoxious for a somewhat professional product, but I keep the enclosure under my desk so it doesn't really bother me.

Overall Review: First one I got was DOA, but I was able to RMA with Newegg without any problems. The fan noise doesn't bother me, in fact I think for an enclosure with 8 hard drives it's pretty quiet.

Comments: While this is a SAS enclosure with 2 minisas ports, it cannot be used simultaneously by 2 separatehost systems. For that you would need a Dell MD3220, or HP P2000, or the Sans Digital AccuRAID series. Or a NAS.

Also, since this is a jbod enclosure, if you need to make raids, you must connect to it with a raid sas controller installed in your host system.
