Now that I have bought this unit I feel really pleased with it and even if it is already fully working with the Hard Drives I had around I have decided to start saving for some new disks.
My plan is to finally buy at least 3 identical new HDD of around 2 Tb each to then fully benefit from the RAID option of this unit.
But one step at the time.
This unit has five hot-swappable bays and can support individual drive, RAID 0, 1, 3, 5, 10 operation with a USB 3.0 interface. The unit itself is stylish and elegant in its aesthetic, featuring a matte black curved aluminium outer shell, and elevated rubber feet at the base.
The front shows the five ventilated flip open bays, each with their own activity LED indicator and a single power button. The bays themselves have a simple security lock with 2 keys provided.
Opening the bays and peeking inside, I can see the use of a PCB back-plate to connect with the drives, which slide in “tool-less” and in the easiest way I have ever seen. Metal “rails” guide the HDD that is then held in place with a tiny tab at the end and the spring tension of the cover pushing against the front edge of the drive. The bay door is linked to a roller actuator at the rear which pushes out the drive from the back-plate when the cover is fully open.
The rear of the unit has a large 120mm exhaust fan that provides for cooling while keeping the noise under control. A single USB 3.0 B connector for the data and a special 4-pin power connector is used to supply power to the unit. The provided Orico branded power supply is rated at 12v 6.5A and potentially I feel that is a bit under-powered as this (when all 5 disk are in place) only gives each bay around 1.3A when most drives require about 1.5 to 1.8A. However when for a short period of time I have tried to fit all 5 drives (by borrowing a couple from a friend), the unit still worked just fine. The supply is provided with a UK cable connector and a European one too.
A set of DIP switches is used to configure the RAID mode, with a SET button used to perform the configuration. This feature is great and very easy to use as initializing new drives involves setting the switches to the clear RAID position, pressing and holding set when turning the power on, until the unit beeps continually to confirm the selection, and then repeating the process with the desired RAID mode. A great utility software from ORICO can be also downloaded easily (and free) if help is required with the RAID setting. The software is: ORICO RAID HW Manager software and can be found on the ORICO website. On the negative point regarding the RAID setting and specifically the configuration pin at the back of the unit it is my duty to point out that it is possible (but not likely) to press it by mistake. The pin sticks out just enough to be caught when handling and moving the unit and if this happened while the unit is working and powered on I feel that some data lost will be. inevitable. In my case anyway the DAS is safely on the desk.
Curious of the build quality of this product I have also attempted taking a few pictures of the motherboard of the unit to check on the quality of soldering. Happy to report that everything looks fine and well built.
Setting up the ORICO unit is a breeze. Initially I tried with a single drive, close the drive bays with sufficient force and lock it and connected the unit to my PC. Since everything worked well I picked up a couple of oldish (but identical) 256Gb drives I had around and I tried the RAID function. Firstly I fitted the drives. Then I plugged in the power adapter and configure the RAID using the DIP switches as mentioned earlier. Finally I attached it to the computer and begin using it without any further hassle. However as previously mentioned, there is also monitoring software which can be installed to perform diagnostics and provide alert capability on the array.
When dealing with RAID configuration it is important to understand all the different options and minimum requirements of drives needed:
-RAID 0 will combine all drives to one and improve performance.It is ideal for high performance massive storage.However it provide no fault tolerance,Any failure may causes loss of all files
-RAID 1 will set another drive to mirroring backup of the first drive.It will not improve performance and cause one drive not applicable.However it is ideal for safety
-RAID 3 and RAID 5 will set one drive to backup disk of others which combine as one.It will improve some performance and backup all files with few volume lost(one drive),It's a economical solution
-RAID 10 is Combine of RAID 0 and RAID 1,Four drives can build RAID 10 ONLY,Two drives be mirroring backup and another two combine as RAID 0.If you wanna ultra performance of RAID 0 and premium backup of RAID 1,RAID 10 is the key solution
"RAID level 0 – Striping
In a RAID 0 system data are split up into blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, this offers superior I/O performance. This performance can be enhanced further by using multiple controllers, ideally one controller per disk.
RAID 0 offers great performance, both in read and write operations. There is no overhead caused by parity controls.
All storage capacity is used, there is no overhead.
The technology is easy to implement.
RAID 0 is not fault-tolerant. If one drive fails, all data in the RAID 0 array are lost. It should not be used for mission-critical systems.
RAID 0 is ideal for non-critical storage of data that have to be read/written at a high speed, such as on an image retouching or video editing station.
If you want to use RAID 0 purely to combine the storage capacity of twee drives in a single volume, consider mounting one drive in the folder path of the other drive. This is supported in Linux, OS X as well as Windows and has the advantage that a single drive failure has no impact on the data of the second disk or SSD drive.
RAID level 1 – Mirroring
Data are stored twice by writing them to both the data drive (or set of data drives) and a mirror drive (or set of drives). If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continues operation. You need at least 2 drives for a RAID 1 array.
RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single drive.
In case a drive fails, data do not have to be rebuild, they just have to be copied to the replacement drive.
RAID 1 is a very simple technology.
The main disadvantage is that the effective storage capacity is only half of the total drive capacity because all data get written twice.
Software RAID 1 solutions do not always allow a hot swap of a failed drive. That means the failed drive can only be replaced after powering down the computer it is attached to. For servers that are used simultaneously by many people, this may not be acceptable. Such systems typically use hardware controllers that do support hot swapping.
RAID-1 is ideal for mission critical storage, for instance for accounting systems. It is also suitable for small servers in which only two data drives will be used.
RAID level 5
RAID 5 is the most common secure RAID level. It requires at least 3 drives but can work with up to 16. Data blocks are striped across the drives and on one drive a parity checksum of all the block data is written. The parity data are not written to a fixed drive, they are spread across all drives, as the drawing below shows. Using the parity data, the computer can recalculate the data of one of the other data blocks, should those data no longer be available. That means a RAID 5 array can withstand a single drive failure without losing data or access to data. Although RAID 5 can be achieved in software, a hardware controller is recommended. Often extra cache memory is used on these controllers to improve the write performance.
Read data transactions are very fast while write data transactions are somewhat slower (due to the parity that has to be calculated).
If a drive fails, you still have access to all data, even while the failed drive is being replaced and the storage controller rebuilds the data on the new drive.
Drive failures have an effect on throughput, although this is still acceptable.
This is complex technology. If one of the disks in an array using 4TB disks fails and is replaced, restoring the data (the rebuild time) may take a day or longer, depending on the load on the array and the speed of the controller. If another disk goes bad during that time, data are lost forever.
RAID 5 is a good all-round system that combines efficient storage with excellent security and decent performance. It is ideal for file and application servers that have a limited number of data drives.
RAID level 10 – combining RAID 1 & RAID 0
It is possible to combine the advantages (and disadvantages) of RAID 0 and RAID 1 in one single system. This is a nested or hybrid RAID configuration. It provides security by mirroring all data on secondary drives while using striping across each set of drives to speed up data transfers.
If something goes wrong with one of the disks in a RAID 10 configuration, the rebuild time is very fast since all that is needed is copying all the data from the surviving mirror to a new drive. This can take as little as 30 minutes for drives of 1 TB.
Half of the storage capacity goes to mirroring, so compared to large RAID 5 or RAID 6 arrays, this is an expensive way to have redundancy."
I have tried running a few benchmarks on my machine (Intel I7 4790K @4.6GHz with 16Gb DDR3) on RAID 0,1 and 5 and added the results to the video attached to the review. Weirdly the maximum reading speed result in RAID 0 is more than twice as much than in RAID 1. This result is in theory impossible but I wonder if it is also related to the age (and reliability) of the old Hard Disk Drives I was using. I am so looking forward to buy some new and fast one!
Anyway... overall I love this product. Well built, incredibly versatile and easy to set up; this is a great drive for multiple HDD/SSD even when not using RAID. Having the RAID option is just the cherry on the cake!
If you have any questions please email me directly (email included in my profile) as for some reasons I am having problems receiving questions on my Amazon account. Thank you.
So, the good points. The case is sturdy, well built and looks pretty good too. Obviously some thought has gone into the design. The photo does not do this thing any justice. Sitting on my desk, with the leds lit up it's quite attractive. Installing drives couldn't be more simply. The bay door unlocks from a thumb catch (and key if you wish to lock the door), you slot in the drive and push the door closed witch seats the drive firmly into the dock and mounts it onto the power and data connectors at the back. It's is just that simple. No tools, no messing around, no fiddly screws, no hassle. - Oh yeah, one thing that should be obvious but may not be. DO NOT mount drives while this unit is on - while it might work, chances are you won't be lucky and could cause a variety of bad results. Laptops and desktop computers had no trouble recognising the unit or the drives mounted inside. Formatting is about as simple as windows can make it and the drives are raedy. If you get the 5 bay like I did, you'll have 5 (or however many drives you install) discs available to you. This is so easy I can't help but wonder why it's been so hard finding something like this.
Other good things. It's quiet, surprisingly quiet.Hard drive platter hammer is minimal, fan hum is minimal and overall noise generation is minimal. I was very pleased when I started shifting things between drives and there was no hammer like I get from standard desktop storage devices. Very nice. No clue how they achieved that, but I'm not complaining.
Third good thing, all the cables and bits you need come with this unit. So it's ready to rock as soon as it's out of the box. Power switch at the back is very positive, so no chances of knocking it accidentally and disturbing the power. The power lead however is a tad wiggly when mounted - so you might want to keep any eye on that and make sure it isn't being knocked by anything. USB cable fits nice and tight and doesn't move in the socket, so data transfer shouldn't be corrupted. I've not noticed any except where noted below.
No,w the bad things.... The door lock is not secure, it is possible to open the bay door even when it is locked with the key. I found this out when a small person wanted to see what was making the light flash. I know, I know, my fault for not paying attention. Unfortunately this seemingly minor action trashed all five drives and I had to spend several days recovering the partitions. Oh well, lesson learned, don't leave it anywhere small fingers can get at it, and make sure there is a barrier of some sort to discourage fiddling.
It is not a good idea to pick this up and move it while it is operating. It feels somewhat like a gyroscope if you do this, and tends to want to twist to the right. Not to mention that with drives inside and the alloy case, it's quite heavy. This is an important point, do not mount this unit on anything that is weak or likely to collapse, fully loaded this is a weighty piece of kit and if it falls, the result could be disastrous, as well as potentially very painful.
Second bad thing, although not truly a bad thing for the drive housing. This unit powers down very quickly. Unless you have some sort of keep alive function running, the drives spin down and power off. Okay, that's good, it saves power, prevents excessive heat generation and generally extends the life of the hard drives. However, windows being as stupid as it is, doesn't send a sufficiently distinct enough signal, and it is entirely probable for this unit to power down while large file transfers are going on. This results in one, and sometimes two irritating results. First, the file is trashed, second, the partition is trashed. So far, in the short time I've had this thing, I have had to rebuild the drive stack five times. Okay, lesson learned. When transferring large files, make sure that something is keeping the drives active. if you can't be bothered with a command line tool, then set a defragment utility off on one of the drives. Anything basically that keeps the thing busy while you're moving stuff around. More I think a downside of Windows to be honest, but it is annoying that this thing powers down while it's busy. Surely if it recognises activity enough to turn the led from blue to red, it should know not to power down. Oh well.
Other than that this is running sweet as a nut, data transfer is fast enough not to be irritating and slow enough that you can track what you're doing. Even with the drives running, the fan seems to shift enough air to keep them moderately cool although the mounts could perhaps be a little further apart to allow easier air flow. I am not sorry I spent the money on this, even with the annoyance of rebuilding the drives, it has and is working pretty much flawlessly and as it should. There's just a small learning curve to owning one of these - as with anything. If I need more storage in the future, I won't hesitate to purchase another of these cases, it's doing precisely what I wanted, the way I wanted to do it, and it looks good in the process. You can't ask for more than that.
Absolutely loving it, it has made my life so much easier, with a lot less farting around swapping caddies or messing with USB extenders.
As simple as it could possibly be, any 3.5-inch HDDs you wish to use simply slide into a bay, no carriers or screws are needed. Although not designed or intended for 2.5-inch drives, they could be used with appropriate carrier/converters but they would largely defeat the tool-free nature of the device.
There is good labelling at the rear to indicate the switch combinations for its various RAID, JBOD or concatenated (BIG) settings making assembly and set-up very simple and quick. There is a SET button that needs to be held in while the enclosure is powered up to ensure that a setting is registered. All switches and connections are at the rear, out of the way when in normal use.
The doors fit well and lock with the keys provided. Comes with the appropriate essential cables. No HDDs of course. That is up to you to supply.
Would take up to 40TBs of HDDs. SATA connections in the back of the cabinet. Just open the door, slide your chosen HDD in and close the door.
Lock it afterwards so no busy fingers can interfere with it. Plug and play, but don't forget to power down before changing the drive.
Recommended to expand your storage capacity as you can afford it. You only have to choose which capacity of HDD you can afford to populate it.
Personally I'm going for the HDD SSD hybrids to give speed and also capacity with reasonable outlay.
