Hi-Rely RAIDFrame: External Disk-To-Disk Backup Via eSATA
Cons And Conclusion
Unlike the seven bay High-Rely eSATA solution we tested two years ago, the RAIDPacs lack the environmental alerts and displays that the former’s disk cartridges have. True, the RAIDPacs do have basic indicator lights and sounds, but there are no extra readings beyond that. Given its current design, knowing whether you have a problem or are just operating normally is not that obvious to someone who hasn’t read the manual.
The overall construction, as I mentioned above, is sturdy. As such, I would like a tool-less construction on the RAIDFrame chassis and the RAIDPacs. Removing twelve screws to access the hard drives is a little excessive, and streamlining the process would be appreciated.
In terms of performance, the RAIDFrame wasn’t designed to be a top performer. It’s not as fast as an internal SATA drive due to the fact that you're sharing the bandwidth of a single 3 Gb/s connection between as many as 15 drives, but it does work faster than USB. With that said, consider this: if the RAIDFrame were built for top-tier speed and performance, customers would have to pay a lot more for it. Instead, Highly Reliable provides a supportable, easy to use backup device with basic functionality that does what it’s supposed to do.
When looking at the price of a single RAIDPac, you’ll spend over $1,200 for 4.5TB in RAID 5, and that isn't including the $3,600 price tag of the chassis itself. If you go online, you can probably build your own eSATA solution for less than $700. However, I’m not completely convinced that the RAIDFrame should be called overpriced just yet. Take into consideration the quality of work that been put into the design of the RAIDFrame chassis, the portability of the RAIDPacs, and Highly Reliable’s effort in creating a simple backup system that has some pretty flexible options. For an IT admin in a medium-sized business to part out and validate a storage system like this, the time spent and question mark on reliability are almost compelling enough reasons to default to a built-up configuration like this.
Conclusion
When looking at the RAIDFrame’s overall design and feature set, there may not be too many competitors. As hard disks get bigger, cheaper, and more reliable, the number of those folks who are apprehensive about disk to disk backups will decrease. For someone new to backups and restores, the RAIDFrame is a relatively easy tool to set up and use. For IT types who're more experienced with storage servers and JBODs, Highly Reliable’s backup solution provides a tool that can be tinkered with and right-sized into any everyday operation.
In my perfect world, I see the RAIDFrame as a great intermediary backup device. The idea of a reasonably quick recovery from disaster is something you can get from the RAIDFrame, especially with files that are constantly being brought back from backups. For long-term archiving, even if you currently go with tape as your end-point back up solution, I’m sure the advantages we get from hard drive based backups will only get better and better.

yyrkoon Perhaps I missed something, But I am curious as to how they got 3 drives per port on the port multiplier. I am familiar with port multipliers, but not the technology they use here apparently.Reply
Also, on a side note, I think this device would be more useful if it allowed you to run RAID 10, but with two out ports. Perhaps even multilane would be in order in this case ? -
yyrkoon Let me clarify what I said above. I feel the device would be "better" if they allowed it to be configured to run RAID 10 using two RAIDPacks.Reply -
jeffunit Nice hardware, but a bit spendy. My software based raid 5 array has higher performance over gigabit ethernet, uses commodity parts, and is much cheaper. I am sure my array costs well under $1000 with 8 750gb drives. Since I am using supermicro hot swap sata drive cages, all I have to do is press a button and the drive comes out. 4 screws, and the drive is removed. Takes well under 5 minutes to remove a drive and put in a new one, and it just takes a philips screwdriver.Reply
And why are there two 450w power supplies? Even if the box is full, that is 30 watts per drive, which is a crazy amount of power. If they stagger the drive spin up, they would never need more than 225w tops.

climber This should be a 6Gb/s SATA 3.0 design with port multipliers. If you wanted to back up serious amounts of data to this thing you'd never finish, it would always be in backup mode.Reply -
so if one of the three drives should fail inside a RAIDpac, you have to eject the whole RAIDpac to replace that drive?Reply
That sets the RAID offline ... a RAID 5 should be allow hotswapping a failed disk.
And two PSU but not redundant ? ... doens't seem very HIGH RELIABLE -
thehighrelyguy Although some of these points were mentioned in the article, not being on the front page, these important features may have been missed by a few readers and may answer some of your questions.Reply
1. Each RAID pack has an integrated RAID 5 / RAID 0 controller. This means the RAIDPACs can operate completely standalone without the addition of any special controllers or driver software. Thus, left with nothing but a RAIDPac, you could connect it via eSATA to your motherboard and restore the data.
2. The RAIDpacs use standard SATA hard drives. At present, 2.0TB drives are available making the available capacities 4TB in RAID 5 and 6TB in RAID 0 per RAID pack.
3. There is also a 1 bay RAIDFrame available which can use RAIDPacs interchangeably with the 5 Bay if necessary. The one bay has both ESATA and USB connections for portability and ease of connection. The one bay is substantially cheaper than the 5 bay.
4. The dual ATX power supplies were chosen over specialty redundant power supplies because they are the most widely available power supply in the world making field service for this unit in the dead of the night, practical. The 1 bay has this same feature. By using two instead of one, if a power supply dies, you're not dead, the unit is still usable although some bays may not function.

thehighrelyguy yyrkoonPerhaps I missed something, But I am curious as to how they got 3 drives per port on the port multiplier. The RAIDFrame is not a single RAID system. The RAIDFrame 5 bay is 5 RAID systems. Each hot swappable RAIDPac is a volume. Port multipliers allow up to 5 volumes (drives) to one SATA channel. Hence one SATA channel, 5 RAIDPacs.Reply
