    Does Everything I Ask

    It works with several different RAID options as well as pass-thru which allows it to function as a simple 5 bay enclosure if you just want that. Using it in RAID with Parity (Raid 5) with 5 WD 1TB 1001FALS with TLER enabled on them (strongly ... Read more

    For Raid 5 - Dump the Silicon Image Raid Card

    Includes computer Silicon Image 3132 raid card, extremely slow raid 5 write (our tests ~10MB/s). Compare to regular internal local drive write 30-60MB/s. We basically dumped the Sil3132 card and replaced with High Point RocketRaid 622 card for ... Read more

    1 out of 5 eggs Never Worked!

    Pros: I would have to lie..... About the enclosure to provide any good remarks. I would feel bad donating it to anyone.... takes up space in my garbage can

    Cons: Everything. Tested this enclosure with Windows 10 (drives never appear). Also tested with Debian (latest stable version) the Drives would appear under fdisk -l and was able to create solid partitions with parted. However, I have been unable to perform ANY read and write operations to the drives in the enclosures. mkdir would hang for a very long (TIME). the drives are all brand new and have passed several SMART tests. Also the latest drivers are installed for this enclosure (for both Windows 10 and Debian). It is worst product I've every received from Roeswill.

    Bottom Line: It makes a wonderful paper weight. I Was forced to give it a single egg as a rating. I feel it is 5 eggs - 5 eggs = 0 over all rating!

    5 out of 5 eggs Great for Linux, but not fastest Windows option.

    Pros: * 5 trays, easy to configure.
    * Firmware can be flashed for non-RAID.
    * This one just works.
    * SIL3132 is rock solid

    Cons: * No low-profile bracket for the HBA
    * Pushbutton is a momentary switch. If you turn it off and back on too quickly, it just stays off.
    * Bottom drive is 32C, and each drive up is +1C for 5900RPM drives.
    * Higher failure rates for top slot, but might be Seagate.
    * If a drive is dropped due to error or timeout, the entire bus resets. The multiplier will reset all 5 drives at once. Bad mojo.
    * This is the noisiest device in my stack, but overall, it's not too bad from 4 feet away.

    Bottom Line: I have used this on a Dell PowerEdge SC 440, Dell Optiplex 755 tower, and Dell Optiplex 755 SFF with success.

    I have never been happy with BIOS-RAID devices, so I flashed the non-RAID firmware on the SATA controller.

    For RAID, I use the operating system (RAID6 from mdadm on Linux && RAID 10 / RAID5 in Disk Management in Windows). This adapter and port multiplier gets up to 126MB/sec on my systems. Sure, RAID5 perf is only 126MB/sec, but it's still better than any of the other low-cost options.

    I've been using this for several years now, and have yet to get a decent replacement for Linux.

    There are some SATA-III versions that use Marvell port multipliers and Marvell SATA-6G controllers. Those work fine on Windows, but run in some sort of low-speed mode for Linux (LILO and DebIan 7.7 Wheezy with 3.2.63 kernel).

    I've tried ASM1061 cards, and Marvell 88SE91xx and 92xx cards, all of which take 5-10 mins just to load a boot image, run 5MB/sec for filesystems, and 30MB/sec raw. The same can be said for other enclosures using Marvell port multipliers. I've tried multiple systems (all Dell/Intel though), cables, Linux kernel versions up to 3.2.63 (Debian), and the Rosewill/Silicon Image pairing is the only set that just works.

    On Windows, the Marvell chips are happy, but I still use OS RAID so I can get at devices with SmartCtl, and OS tools for recovery.

    Also note that Rosewill and Sans Digital are the same devices with a different paint job. If you have trouble with one, or success with one, then expect the same for the other if you get the same generation of product (SATA-II Silicon Image vs SATA-III Marvell).

    4 out of 5 eggs It Works Wit 4TB Drives!

    Pros: Working solid for months with no problems.

    Cons: Had one out of six that stopped communicating with the system. It's an older one and out of warranty. It happens.

    Bottom Line: Just got a Seagate 4TB drive and put it in for the heck of it. Fired right up and formatted no problem. I'm using these for JBOD for a home media server, with a total of 60TB. I just wish the eSATA cables would lock into the ports. Otherwise they are great.

    3 out of 5 eggs Respectable product for the price

    Pros: Price to storage density ratio is excellent, speeds in RAID-0/1/10/JBOD are as expected for the interface and drives, around 80-110MBytes/sec sustained. Recovers gracefully from drive failures when configured for redundancy and hotswaps seamlessly without complaining. Seems faster than the RSV-S8, albeit with slightly newer drives.

    Cons: The old Java management software is very poor, as are the drivers. The management system service has to regularly be restarted for the management software to detect any controllers. Half of one RSV-S8 randomly drops out and has to be either unplugged or the system restarted for it to be recognized by Windows again. In its defense, this is in a system with three PCIe cards, two RSV-S8's, and one RSV-S5, all full of drives in RAID-5. I'll point the finger at Silicon Image for these issues anyway, not Rosewill As with the RSV-S8 and other products using port multipliers, initial RAID-5 array builds are very slow to write parity data, as are rebuilds when a drive is lost or errors are detected. Redundancy restore operations also seem to begin without obvious cause and at random, slowing down performance for sometimes days at a time. Write operations to RAID-5 volumes are also predictably slow, with speeds peaking at 20-25MBytes/sec when the array is otherwise idle. This is to be expected, though, with what is essentially software RAID through a tiny port multiplier card. RAID-5 read operations are tolerable. Besides software and performance, the only thing that doesn't make this a 4-5 egg product for me is the lack of 6.0Gbps SATA support.

    Bottom Line: All around it's a pretty solid product that could probably stand some polishing, but well worth the money for anyone looking for lots of cheap local storage.

    4 out of 5 eggs Good with software RAID5 on Ubuntu 12.10

    Pros: Inexpensive. 5-bays. Ubuntu 12.10 sees the card automatically. Quiet.

    Cons: Orange light is a bit bright. Blue would have looked nicer. The trays could have been designed a little better; I would have preferred a screwless design.

    Bottom Line: I am very satisfied with this enclosure. I'm not using the controller's RAID as I have read the bad reviews on it. Software RAID5 on Ubuntu 12.10 works great with it.

    5 out of 5 eggs works for me

    Pros: I'm giving it 5 stars because it does everything I need. Note, I'm not using the BIOS on the supplied card.
    I built a 5-disk RAID5 array under Linux. Linux sees all of the drives as individual disks, since I did not set anything up with the card's BIOS. This is exactly what I wanted and expected, therefore the 5 stars.

    I like the sleds, they work fine.

    Cons: I can't think of any.
    I saw some negative reviews, but that's not my experience at all. your mileage may vary.

    Bottom Line: The box and the server that I attached it to are tucked away in my basement so I'm not concerned about noise, but it doesn't seem noisy.

    4 out of 5 eggs Reliable Enclosure

    Pros: - Relatively inexpensive
    - 5 drive bays w/ drive carriers
    - Comes with a port-multiplier card

    Cons: - Does not have an industrial build quality

    Bottom Line: I bought this enclosure in Jan 2010 to house 5 Seagate 1.5 TB HDs connected to an Ubuntu Server 10.04 LTS 32-bit server and configured using software raid-5 (mdadm). The initial setup was eady, ableit long to form the raid-5 array (which should be a given using this setup). The enclosure and the array has been running without a problem ever since. Never a problem is dropping the array or disks, array rebuilds on reboot... nothing. Oh, and for those who like to be critical of consumer grade or brand <insert name here> drives, I've never lost a drive either.

    If you just getting started or need a simple expansion, I highly recommend this unit.

    1 out of 5 eggs Worst Product Ever

    Pros: None. Well, I suppose the initial setup was simple enough. Minus trying to get SATARAID5 working with UAC on Windows 7. Once that was setup, I was able to create my RAID 5 within a couple minutes. It took forever to set up, but that was expected given 4x1TB HDD in a RAID 5. Probably took over 20 hours

    Cons: Where to start....
    1) Took forever to build the RAID 5 volume. Over 20 hours.
    2) Rebuilds every time my computer restarts or goes to sleep. Sometimes the rebuilds will take 15 minutes, other times it'll take upwards of 3 hours
    3) Random drive(s) drops every couple of weeks. No rhyme or reason to which drive drops. All drives have been independently tested using manufacturer tools and all come back clean. I've put them in different systems and they have no problems, so the HDD's are fine. The box will drop one drive, and then a couple minutes later drops a second drive bringing the RAID 5 down. I will need to pop the HDD's and reinsert them MULTIPLE times along with power cycling the unit a couple times and then eventually it'll successfully rebuild after 15 hours.
    Luckily I have yet to lose data with all of these drops while I've been actively using the files on the RAID. But the frequency at which this happens and the inconsistency of the fix needed means I don't trust this unit beyond its abilities as a paperweight.

    Rosewill support - don't bother responding. I've tried updating firmwares, drivers, the works and the issues still persist. And judging by the other reviewers on here I'm not the only one with the issue.

    I bought this unit thinking it'd be a great cheap RAID 5 box. I've totally learned my lesson and will fork over the extra money for a real RAID box instead of continuing to deal with this paperweight.

    1 out of 5 eggs Good drives randomly dropping out of RAID 5 repeatedly

    Pros: I have no had a single positive experience with this unit, except for the Silicon Image BIOS flasher, which was conveniently built into the driver information page in the device manager.

    Cons: Almost everything.

    Bottom Line: From day 1 this thing was a travesty to configure and set up. Getting the latest bios and drivers was a Herculean task - a newbie would have been lost even considering the idea - even if they found the download pages, there is practically no system of organization or an organized release structure that lets you know exactly what you need for your device and which are the latest versions. The Rosewill website is truly awful in this regard - the Silicon Image website was miles better but would still be confusing for somebody who just wanted the latest files.

    The Silicon Image controller letting me flash a new bios from the driver page in device manager was nice, but this thing should have never been put on the market.

    SATARAID 5 (the GUI RAID configurator) was clearly designed by chimpanzees, as nothing about it is useful or intuitive either. A day after my first RAID 5 configuration (5x 2TB drives) was finished initializing, 1 drive dropped out, then a second dropped out a few hours later. Rebooting brings the drive(s) back but of course SATARAID wants to re-initialize the thing, thereby rendering the unit practically useless. All 5 drives in the unit have been independently tested and thrashed in another machine using a specialized version of linux designed only to thrash a whole bunch of drives at once, report results and whether any died, and then power down. All drives were fine after a 72-hour thrash, with perfect health scores and throughput ratings. However, drives are randomly dropping out of this RAID unit. It's a different drive almost every time. I have tried swapping cables, swapping which port on the SI card the cable goes into, Ive tried it in another machine, a different version of windows, etc etc, and this unit consistently fails to provide a complete, healthy RAID 5 configuration for more than a few hours before dropping one or two drives.

    Avoid at all costs.

    I will be saving money for an Areca card and Areca enclosure instead. This will teach me for trying to save a few bucks.

    I will be RMA'ing this through Newegg immediately for a full refund.

    2 out of 5 eggs What happened?

    Pros: Quick way to add 5 hard drives.

    Cons: Drives disappear, slow down or stop during transfers.

    Bottom Line: I have had four of these for a couple of years now. They all worked fine with no issues. I am using a Syba 4 port esata card with PORT MULTIPLIER, (thats the key when selecting an alternate controller card). A power supply died on one of them, so I simply wanted to replace it. All kinds of trouble since putting this one in. Thinking drives were failing, I'm convinced it something to do with this unit. When I move drives into any of the other ones, no problems. I am past Newegg's return policy so, I might just gut this one for the power supply and put it into the one that did work with no issue. Rosewill RMA process is not exactly user friendly or well automated like many other companies. Maybe I just got a dud. Like I said above the rest of these units I own are just fine and have worked great with near 24/7 operation for weeks at a time.

    2 eggs for a letdown on a product I found to be decent previously, and for a difficult RMA process by the manufacturer. Newegg has nothing to do with this, I simply waited too long to install this unit. At least I have a replacement power supply for the one that did work.
