What happens if you use "Green" Drives? Is it possible for the drives to idle when they aren't in use, or do they always run at a high RPM?

I've never used them with green drives; instead, I've only used them with regular hard drives. Unless you put the Mac to sleep, they stay at the same RPM. PCs, I'm not sure about. br>I recently replaced this dock with a SATA dock and a SATA card, which is the fastest and most reliable external drive connection available.

I have two hdds that were in a raid-configured server; if I connect them to the cavalry cahdd, will I be able to access the data on those hdds?

You will, in fact.

Can I remove the drives from the external case and copy them with this unit if I have an external drive that is actually two drives in a RAID array?

You can copy any drive, but if the two drives are part of a single raid setup, you must be cautious about how the raid is implemented. This is something you should probably check with an IT professional about first.

Selected User Reviews For Cavalry CAHDD Series USB Dual-Bay Dock with RAID Feature EN-CAHDD2B-D

On the market, the best low-cost RAID
5/5

This docking station won't be able to replace dedicated external or internal systems such as Drobo or a Promise RAID card in a motherboard, but it will get the job done. I use my drive for mirroring, and I've been using it for a month with two 1 TB drives and it's been working great. The maximum storage capacity is reportedly 4TB, which appears to be quite adequate (x2 two-terabyte hard drives). The drives synchronized instantly and without any additional prompting. For quick backup, this is a great option. br>br>This device only has a USB port, though there appears to be space on the internal circuitry to solder an eSATA connector, so it's possible that another model exists. It doesn't have a graphical user interface and instead relies on back-panel switches to switch between JBOD, RAID 0, and RAID 1 RAID modes. I don't see how you could use this drive to do RAID 0 1 because it requires more than two drives, but that could be because the four-bay version of this external array does and uses the same internal circuitry. br>br>The switches change the binary sequence of the Calvary RAID device, such as 011, 101, and so on; for those who don't care, there are three simple up/down switches in the back. You must consult the manual to determine how to orient the switches, but this is not difficult. br>br>JBOD appears to work well as well, but I have not thoroughly tested RAID 0 to determine its reliability. However, I would not bother with it because RAID 0 is rendered nearly useless because you must use USB as the transfer medium, slowing the speeds to that of a regular HD. The USB drivers are simple to install, but they only appear to work with Windows, as far as I can tell. So far, I haven't come across anything that says it works on Mac or Linux, which is unfortunate. It may, however, work, but I haven't tested it on anything other than Windows 7 at this time. In case it isn't stated in the ad, the manual also states that it works with Windows XP and higher. br>br>The activity lights on the drives are also useful for ensuring that the data is properly syncing with the drives. The drives do get a little warm for an external system, but that's not a big deal because they're out in the open. I'll also point out that the device can hold both 2. 5 and 3. 5 inch drives are easily exchanged because they are secure and easy to use. br>br>As for extras like customer support and warranty, they both appear adequate but far from perfect; realistically, if you want a good RAID system (I'm talking average, not even the best available), you'll have to spend a few hundred dollars on good customer service, warranty, and overall RAID system. In general, don't expect miracles from something that costs $40, and make sure you're not a casual RAID user. RAID is for people who know computers or can afford to hire IT guys; otherwise, you'll have trouble understanding and using this device. My recommendation is to get a basic external HD until you can afford something better, because it's in the average user's best interest to KISS (Keep It Simple SillY). There are plenty of good rugged backup solutions that are easier to use, such as the Seagate mobile drive series, which are designed for average users.

4/5

If you have a place for it, this is a very special little device. Continue looking if you're looking for a low-cost USB enclosure. There is no barrier between us and the outside world. It's a small dock with no fancy features. Drop a bare drive into one of the bays (connector end down) and let gravity take care of the rest; there's no cooling fan because it's open. It's great for quick insertion, but it's a bit risky to move around with. The hard drives are going to fall out. However, it isn't meant to be taken with you. I've set it up next to my computer and slid in a couple of 2TB drives as a backup. You can choose between JBOD, Raid-1, and spanned using a small set of jumpers. I've got the drives set up as a single spanned drive and haven't had any problems (except for one that I'll mention at the end of the review). This is a nice way to turn a pair of too-small shoes into a pair of too-large shoes. Small drives are combined into a single larger drive. This is a cost-effective solution because I have the space. You can also use it if you need to look at an old archive drive; simply plug it in and use it. There's no need to spend money on an enclosure for a drive that'll only be used once in a while. br>br>I attempted an experiment that failed miserably. I used OSX Mountain Lion to create a spanned 4TB drive, which I then partitioned into 1TB and 3TB logical drives. This threw Time Machine for a loop on two occasions, resulting in a corrupted device that needed to be repartitioned. I'm not sure if it was because of firmware in the Cavalry Enclosure, Time Machine problems, or OSX problems. Most readers will probably think it was a stupid thing to do (although it felt clever at the time), and it was in this case. Set it up as JBOD if you'd like two drives. Spread it out if you want a large one. If you keep it simple, the device should work just fine.

After you've tested and learned how it behaves in various environments, you'll have the best tool
4/5

Because I believe I've already written a review, I'll keep this one brief. br>Because I am a techie geek, I know a little bit more, or at least from time to time, and I have the time to learn how my stuff works. So here it is: br> br>I put my skills to the test in three different settings: Mac, Linux (Ubuntu), and Windows are the three operating systems available. br>It's really good. If you don't want to pay $19, there is a Mac Driver for NTFS, but only for Seagate. The Paragon driver received a score of 99 out of a possible 100. Consult the manufacturer's website; however, be aware that it has been known to become corrupt, resulting in nothing being readable from the MAC. To clean the disk and reformat the unit, I backup everything with a linux machine. Then I copied all of my data back to the MAC and reinstalled the driver. So far, everything has gone well. br>Raid is a fantastic application. Simply incredible. I began mirroring the HDD while on Linux, installing a clean or new disk, and then shut down the computer within an hour, and the Dock continued the mirroring process without issue. Later, I returned to my desk and double-checked that both HDDs were in working order! br>br>By the way, it took me a week to figure out how to use it. It was a nightmare at first, because I couldn't figure it out. Information is scarce in the manual. If you eject a disk in Linux, the entire dock is ejected as well. So, if you don't have raid (2 separate disks) or jbod, both disks will be ejected at the same time, so be aware. If one disk is copying and the other is idle, you can eject one and perform hot swapping on the other. llllllol Well, good luck with that, it could get corrupted. br>br>And because it is so sensitive, if your desk shakes or you trip over it, it may disconnect the disk and think you need to mirror the units. If one of the disks is blank, this can be a problem, so take care when inserting new media. I know I gave it four stars, but when I first started writing it, it was a nightmare, and I was only going to give it one.
