What’s in the Box?
The box contains the enclosure, a screwdriver and screw set, hard drive handles, a power supply with 3 different power cords, eSATA cable, USB cable, 6-pin and 9-pin Firewire cables and a manual and CD.
A Closer Look
Adding Drives
In order to add a drive, or several drives you first have to fit the drive handles to the front of each drive.
Then you have to open the front panel and then remove the inner panel to gain access to the drive bays.
Then just slide the drives into the drive bays and refit the inner panel and then the front panel.
One thing to note, if you are only installing two drives, you are advised to fit one of them in the bottom slot.
Using the Enclosure
Once you have added the drives, you need to set the hard drive dip switch (which is located on the back of the unit under a little cover) to reflect what you want (and also depending on the number of the drives). In my case I wanted to use RAID0 (Spanning) so I flicked both switches down.
Thanks for this review, there are not many reviews of these products available. It would have been good to see the benchmarks between the different RAID modes and if it really makes a difference, but nice to see the stats in there anyway.
Thanks John – unfortunately I dont have them anymore as they had to go back, but if I get some more in the future I will try to do something.
this wasnt a review. all the information is from the manufactures website.
is there software that comes with it? how easy is it to use? are there instructions? if so are they in english? compared to other units youve used how does this compare from a user stand-point?
it is a review – and I’m guessing by your comments you didnt bother to click on pages 2 through 4 then, only the 1st page!
I’m trying to get one of these working… I’m on the second one. First off, what it does it to build all the drives into one big one, unlike an internal PCI RAID card which allows you run the BIOS and other software to configure it into multiple drives.
The end result is that if you have more than 2TB exposed then it won’t work with XP. Forget what they tell you… I spend three sessions on line with them and looked at their online documentation and they told me it would work. Then when I got it, it had additional information… well you got it, Win7 saw it but XP did not.
To top if off, they say not to build multiple partitions off a single drive in disk manager. Huh? So, bye bye using a Win7 to mount it into several 2TB partitions that can be exported via SMB. ( I don;t believe them on this yet… still trying).
So, right now I’ve wasted a whole week on this brick. Unless you are fully into Linux and Win7 you might well forget it. After all, who’s going to buy a RAID box and not loaded with 6 or 8 TB at the very least?
I’m still trying… and, yes, BTW, i did read this lousy “review” before I bought it. I say LOUSY because it was not a review at all.
You say it’s a lousy review – what do you consider a good review to be then? I’m sorry you are having problems with the product but that’s got nothing to so with the review! This review covered everything so I don’t see what your issue is?
Because the review sounds like a reading through of the documentation not a sit down and trying with realistic sizes and at a few OS. And, did you even read the included manuals in the CD? They present additional information that their online support doesn’t have! I emailed to them. I mean they are good, but they can only be as good as the information their company gives them.
Update… I finally got it working with Windows 7 Pro 64 bit. It does not work with XP at all with volume sizes of more than 2TB because it presents a single volume to the PC and it can not be loaded at all.
This is not a problem with the datalink, as eSATA, Firewire and USB all connect and are detected by the RAID.
So it’s an issue with the OS. I guess Ubuntu will work fine too but I did not hook it up to that box. I have no clue about Apples.
It would be nice if they offered a BIOS program -or some other means- to program the RAID chip to present different volumes to the OS… as I do with SATARaid5 in my other desktops. For example, with SATARaid5 I take a 3 disk, 6TB RAID5 and mount two 2TB volumes. Then the OS sees each volume as a separate disk and it can be formatted with MBR. This box, as hard configured, will present very large volumes that will easily exceed 2TB and hence require GPT -which is not available in XP.
On top of that they warn you not to create multiple partitions on such a disk. Which sucks since I figure on using a Win7 box to mount the GPT disk, create multiple 2TB partitions and then sharing them over the network as 2TB drives. The technician and I were still not quite sure why that went into the HFR-SU252 user manual included in the disk. That’s my next project. I need to make that work so that XP boxes in the network can use this RAID enclosure.
Bottom line… pretty much useless with XP unless you are going to use very small drives.
Also, it is VERY picky on how to configure it. You must disconnect it from the PC and cycle power at least twice every time you make a configuration change: (1) disconnect, (2) power down, (3) power up. (4) change mode, (5) click on rear button (6) power down, (7) power up, (8) connect to PC…. and this assumes that you did not change the number of drives, if so you have to add that step between (2) and (3) above.
BTW- I hope my ‘review’ stays up so people can google it. I really saw nothing of the kind on the Internet.
OK… So I finally got it working but I had to go out and buy a used WIndows 7 Pro 64 bit machine.
I got it configured as a RAID5 with four 1.5TB drives, hence it looks like a 4.5TB disk to Windows. I initialized as GPT using Windows disk manager and then partitioned it into three chunks: 2TB 2TB and 500GB and exported them to the workgroup so that the XP ,machines can all read and write to it ( taking into account the added complication of NTFS access permissions under Win 7).
I don’t know why they say not to do that, but it works fine so far. It’s actually a nice unit because is shuts down the discs when not being used, so that ought to save some money and wear and tear.
Here’s the additional info that does not appear in their on line info… only in the included CD:
1. Changing the RAID mode will cause data lost.
2. Please refer to the instructions when switching the RAID mode, otherwise the execution might fail.
3. Interface of USB / eSATA can not be used at the same time.
4. When using RAID function, HDDs with the same brand, model and capacity is strongly recommended.
5. When using RAID function, more than one HDD partition is not recommended.
6. Under Windows Vista / 7, users can enable GPT when initializing HDD with a total capacity of more than 2TB.
7. Older OS may not recognize the device if you use a different operation system than Windows Vista / 7. For more detailed information about GTP, please visit:
http://www.microsoft.com/whdc/device/storage/GPT_FAQ.mspx
8. If users enable MBR by mistake, in order to clean the partition table, you have to switch to another RAID mode and do the RAID mode switch all over again referring to Setup. Then go back to the RAID mode you want, repeat the previous actions and enable GPT when initializing HDD.
9. For Macintosh users: the total capacity of more than 2TB could be recognized only for the operation system is 10.4.11 Tiger or later.
10. Do not connect the device to the SATA on board port of the motherboard. Either use SATA to eSATA PCI-Express or SATA to eSATA PCI add-on card, otherwise the PC (Windows / Macintosh) may not recognize the device.
11. In RAID 1, HDD1 and HDD2 must be installed, otherwise the PC (Windows / Macintosh) can not recognize the device.
12. Rebuild time is based on the capacity, e.g. it takes about 1 hour for 200GB.
