1 out of 5 eggsHello???

Pros: Economical, no trays needed.

Cons: Requires the inserted drive connectors fit a standard positioning. Won't work with SSD adapters. In fact mine doesn't work at all. Computer not detecting any standard SATA drives I inserted!

Other Thoughts: Very disappointed with this product. Previous products using trays worked perfectly. Now they are "obsolete".

1 out of 5 eggsDefinitely needs work

Pros: cheapish

Cons: spring in back prevents sata connection

Other Thoughts: I had the same problem that the others had with the very tough spring. I decided to pull the spring out and found they were only attached by a small screw. After pulling out the first one, I unscrewed the second through the fourth. Now that the spring is out, all 4 drive bays are working as expected. The only "gotcha" is that now my drives don't come out when I open the door, and the plastic door will break easily to remove that connection. Ideally, the spring should stay in, but a smaller spring for less force (perhaps cutting it in half and replacing the spring back in).

Since i dont need the drives to come in and out often, I'll cross that bridge when I need to.

1 out of 5 eggsNew version plain doesn't work

Pros: Cheap

Cons: Doesn't work.

Other Thoughts: I purchased one of these in 2011 and it worked like a charm (it still does in 2013). The fans are a bit noisy, but since the server is sitting the garage I couldn't care less.

As I was building a new server I decided to go with a proven thing and bought several of these backplanes again. What a mistake it turned out to be - I should have checked the recent reviews rather than just glance at the average review rating (which mostly comes from old reviews).

I bought two of these and immediately had to RMA one because it had broken parts within it. The other one along with the replacement plain didn't work. It would sometimes work with one drive in, rarely with two and putting the third one it is guaranteed to cause all of the drives not to show up in BIOS or OS.

I guess the new-fangled (industrial grade spring is to blame). I don't know and I don't care. This device is unusable. Period. Newegg should just stop selling these!

1 out of 5 eggsThis version is fundamentally flawed.

Pros: Um... the fans spin.

Cons: Doesn't work out of the box. Drives aren't registering with the system. Immediate RMA candidate.

Other Thoughts: I have to concur with the other two recent reviews on this product. I also have both versions of this hotswap bay and the original version has worked without issues since I got it. I use it for my WHS box and apart from a mod to quiet THE INCREDIBLY LOUD FANS! (why does no one make hotswap bays with quiet fans...) it's worked just fine. I only swap drives when there's a problem, so I didn't need anything industrial grade for my purposes.

But this new version has a fundamental design problem and I think the other reviewers got it right: there are now springs mounted on the back plastic that stick out of square holes in the PC board at an angle and end up parallel to the SATA connectors. The original doesn't have these; I assume someone thought it would help to push the drive out or to secure the drive in... When a drive is inserted, the spring is pushed back but also pushes the PC board and the sockets back too. What an IDIOTIC design!

I installed this bay with 4 drives from the get go, and none of them registered with the system. I removed them one at a time and restarted the system each time: none of the drives ever showed up in the BIOS.

IMO, Newegg should send these back to the manufacturer and stop selling them altogether. This version is fundamentally flawed. Caveat emptor...

1 out of 5 eggsFundamental design Flaws go back to old style

Pros: screwless just insert the drives
good price

Cons: The metal spring clips on the backplane literally bend the backplane seperating the sata connectors from the hard drive
it did not read any of my drives. so it was DOA

Other Thoughts: The new style is a failure they inserted metal spring clips in the back that are so strong that they literally bend the backplane and the sata contacts on the back plane away from the hard drive. I thought I could just remove them and it would operate like the several old style one I owned in the past but DON'T DO IT. you cannot get the drive out with out a hooking it out from the front
I have purchased several of these in the past that where in the old style that worked great these new ones have fundamental design flaws

1 out of 5 eggsReturned them

Pros: I have an older version and the concept is great for server or lab systems where you need to change out the drives regularly. Bought 2 of the newer version for a new server.

Cons: I have an older 3 drive version of this in a lab system and it has worked great for the past 3 years. This newer version however is not usable. It seems the backplane is too noisy. I was only able to use it with one drive installed (did not matter what slot it was in.) Some times 2 drives would be recognized 2 were installed (again independent of slots used). If 3 drives installed, a few times one would get recognized, but usually 0. With 4 installed nothing recognized. Bought two of these and both displayed the same problem. Tried multiple sets of different drives and different systems with same results. Newegg RMA process was great as always.

Other Thoughts: This newer version has flimsy slot doors compared to the older version. It seems they would break easy and with the mechanics of seating the drive, when the door is broken, the slot is useless.

5 out of 5 eggsWork

Pros: I have had these in a server for over 6 months. I do not take the drives in and out. The server runs 24/7. You do have to insert the drives delicately and make sure they are in right. If you do not you can push on the backplane as the drives are pushing on the sata connectors. The cheap plastic locks do not stay locked as the server/tower is on its side.

Cons: I did move the server once so far. Halfway across the US and I had to reseat the drives.

1 out of 5 eggsJunk

Pros: You can easily access your disks.

Cons: It is finicky to establish disk connections at first, and eventually will stop working.

Other Thoughts: There are other reviews indicating this will fail to detect drives after some time. They were right.

The fans are loud, and I did disconnect them. But what does that matter, if it can't detect your drives? Worthless junk.

I'm going to try ripping out the backplane & connecting cables direct. No point in going through hassle of exchange for same thing to happen in a few months. Newegg, why are you still peddling this?

1 out of 5 eggsStay Away From

Pros: Works for awhile

Cons: Only works for a while! Have puchased 8 of these over the past year, all for servers with RAID5. Three of them have failed (drives disappear reseating does not resolve issue). Removing drives from cage and hooking directly to with SATA cable to motherboard, brought missing drives back.

Plastic hinged doors are fragile not designed for frequent opening and closing.

Other Thoughts: I will not be using these in future builds, and am currently removing them from the other servers they are installed in, just too risky. Since warranty is only for same item no use returning to manufactuer.

2 out of 5 eggsLoud and fickle

Pros: The cage is very well constructed. Although its aluminum, it felt solid with absolutely no flex or warping. The trayless loading system was better than I thought it would be (when it works).

Cons: I purchased and installed 2 cages. The first time I booted up, it only recognized 4 of my 8 drives. I reseated the drives that weren't showing up and eventually all but 2 of them came up. Finally, I replaced their cheap SATA cables with some of my good ones and got all drives recognized. Now I was able to boot into Windows; however, once I was in Windows, the system performed a hard shut down. I restarted and tried again with the same result. I restarted in safe mode with the same crash and finally just left the system sitting in the bios for about 3 minutes before it crashed again. During all of this time, I was also greeted with a fan hum akin to a moderate 2u server; needless to say, all of the reviews talking about fan noise are dead on.

I've since removed the cages and am back to a running system. RMA submitted and the cages will be on their way back to Newegg shortly.
