Sans Digital TowerRAID TR4UTBPN - Four-Bay USB 3.0 / eSATA Hardware RAID 5 Tower

Features

Sans Digital

The TowerRAID TR4UTBPN is a four-bay hardware RAID 5 storage tower that utilizes high performance USB 3.0 and eSATA interfaces to provide over 200MBps in performance. The included USB 3.0 port is backwards compatible with widely available USB 2.0 ports, which is a convenient feature when both USB 3.0 and eSATA connections are unavailable.

With built-in RAID 0, 1, 10, 3, 5 with hot-spare and JBOD, the TR4UTBPN provides hardware RAID redundancy protection against hard drive failures. A brand new RAID mode, CLONE or N-Way Mirror, is also introduced to replicate the saved data throughout each installed hard drive. The RAID engine is embedded within the enclosure and performs all RAID parity calculation to reduce CPU utilization from the host PC. RAID controller cards are unnecessary. The TR4UTBPN is the ultimate RAID storage for all storage needs.

5 out of 5 eggssimple is better

Pros: 4 bay for lower price than most 2-3. USB connection is solid and transfer speeds are comparable to every other external USB hard drive I've ever used.

Cons: RAID and eSATA are a bit finicky

Other Thoughts: I got it "to work" with my eSATA card but my speeds were all over the map. In fairness I haven't tested with any other card. I didn't buy it to use as hard drive expansion, i bought it for external backup and archival of older, less frequently used files. Plug it in using USB and it'll run about 70-110 to my dual 4TB hard drives currently in JBOD configuration. If you want more fancy features spend the money and time and see if they work. For me it does everything i need.

3 out of 5 eggsnever received my rebate

Pros: It still works, and I'm happy with the product so far.

Cons: Still a little slower than I expected, and I fear turning it off since it lost my array the first time I powered down.

Other Thoughts: I never received my rebate. This is the first time I've not received an advertised rebate, and I believe that it was due to Newegg's posted rebate form having a watermark on the printout that read "sample" or "example"---can't remember.

I didn't print out the form until the day after the sale, because I was not at home when I made the purchase; so if there was a change, it was surely intentional, and made me eat the price difference.

Yes, I'm upset about twenty dollars because as far as I'm concerned, it's an agreed upon price....much like a handshake, a gentleman's deal. It's now been 4 months, so I don't think I'll be getting it. I might call them because I hope this premier membership is worth something. I paid for it, and so far I'm not impressed with whatever this service is supposed to provide because I haven't seen any benefits from it.

3 out of 5 eggsInexpensive RAID with some flaws

Pros: Inexpensive, HW RAID so OS only sees 1 drive, easy to configure.

Cons: Power supply is questionable (1 failed out of 3, I replaced it with some difficulty). RAID can not be expanded by adding a new drive later: to add a new drive the RAID must be backed up, deleted, re-created with the new drive and restored. This is an omission that took 2 stars. Must remove case cover to insert/remove drives if they are mounted with screws, minor annoyance.

Other Thoughts: I have 3 (now 4) of these units. One PS died after 18 months or so. I bought a new unit then ordered a relatively expensive replacement from Sans Digital ($59 + $20 shipping) to repair the dead one. Difficult to install but not impossible. Tech Support responds promptly to questions. RAID5 rebuild on a 4*2TB drive with one failed 2TB drive took a long time (about 24 hours).

3 out of 5 eggs2.5 years old, doesn't power on

Pros: Simple to setup, flexibility to build several different raid configurations, USB3.0 & eSata support

Cons: device powered off and is failing to power on now after 2.5 years. Waiting for response from Sans Digital tech support as there's no phone number on their site for on the spot service.

1 out of 5 eggsAVOID! AVOID!

Pros: inexpensive

Cons: SUPER-DANGEROUS to data preservation

Other Thoughts: After having to do a very VERY expensive data recovery due to our own operator error, we've been super-careful about following procedure with Sans's enclosures. But within days of recovering from our self-inflicted disaster, the enclosure created its own very expensive catastrophe. When this enclosure fails to see the proper number of good drives inside, it continues to operate, but as soon as it sees the last drive added, it goes into auto-rebuild. While this may seem like a good idea, it's NOT. The enclosure seems to fail to reliably power up and control all the drives within the short window it uses to recognize a "good" RAID set. Consequently it occasionally goes into auto-rebuild on start-up, even when all the drives are present. Annoying, yes. Dangerous, no. But what IS DANGEROUS is that when it fails to recognize two or more of the required drives, then it corrupts its own RAID master directory, rendering all drives useless without a VERY expensive data recovery process. Even when you follow all the instructions. It's just plan bad engineering to make something as elaborate as an auto-rebuild into a non-user-controllable process. But it's even worse to make it so that it craps in its own nest without you being able to stop it. AVOID THIS BOX LIKE THE PLAGUE.

5 out of 5 eggsimpressed

Pros: RAID built in, priced very competitively, works with my WD Red 2TB drives.

Been running 24x7 since I got it and it's still transferring well enough to get HD streaming through my WHS 2011 box, via USB 3.0.

Quiet convenience, easy to share.

Cons: Software sucks a little....needs more development.

Other Thoughts: Still not sure how it will hold up over the long term, but for the price, I'm happy so far.

2 out of 5 eggsMade with cheap unreliable components

Pros: Very fast setup, good performance when it works

Cons: Of the three of these that I have purchased over the past few years, two of them had their power supplies die for no good reason.

Other Thoughts: They are good out of the box, the warranty is only one year, I just had to purchase a $60 power supply to try to bring one back to life. Considering the downtime and the time for repair, I probably would have been better off buying a different brand.

5 out of 5 eggsGreat Service!

Pros: I know some here seem to have had issues with SansDigital service, but I have nothing but praise. After a year of ownership the power supply in my TR4UTBPN died. I contacted SansDigital via email and they were back to me within 24hrs. I returned the unit under RMA and received it back within 2 weeks in full, working order. Their staff was knowledgeable and courteous. They get high marks from me!

Cons: none

Other Thoughts: To be sure, any self-contained RAID unit like this without redundant power supplies is going to be subject to issues such as crashing during a write, which can destroy things like journal entries, rendering your data inaccessible. Much more expensive systems may have two or more redundant supplies, to cover for the eventuality that one of them will begin failing (i.e., "brown-out" process), or outright dies. Make sure you have a full backup somewhere so you can recover gracefully!
