    Lian-Li EX-503B


    One of hot topics of recent was the release of the new Lian-Li EX-503B which in essence, is a multi-drive external storage box.  Realizing that many people including me are looking for different solutions to back up their servers, I was very intrigued by this particular device.  Why you ask, well, several reasons.  For starters it sported a USB 3.0 port, supported all types of RAID (0,1,5,10, JBOD, port replication, and held 5 drives.  So the next obvious question is: Is this a Drobo killer?  The short answer is not really, as this is really a completely different product.  To clarify, let me try and differentiate the two products and then we can get into how good this unit is.

    EX-503B vs Drobo


    Although we all want to compare the two, the truth is they are after different segments of the market.  I believe the Drobo is aimed at a total, do all, be all, storage solution where as the EX-503 wants to be your storage expansion and wants to do it well.  The major differences between these two devices is the Drobo gives you a ton of software, built in utilities, gives you flexible expansion, but it does it a price.  That price is not only dollars but speed.  In the other corner, you have a device like the EX-503B which does not offer utilities, not much in software except to setup the RAID, limited expandability, but it offers it as a much lower cost and performance that is unrivaled from any external unit or NAS I have ever seen.  In short, it does not try to be an all in one solution but rather offers us a way to expand our storage or backup our systems, and it does that extremely well.






    This device has one purpose in life and that is to expand your storage and do it without a performance penalty.  The way I view this box is for those who need to store or backup large amounts of data and want to do without giving up the performance.  I believe this is the ideal box to attach to a server for backing up or synching large amounts of data quickly and cost effectively.  Make no mistake, it will not offer you the software suite of something like the Drobo or Synology, which in most cases is not needed in a WHS backup application, but what it will offer you is a place to backup your WHS data either locally or to remove to an offsite backup location, and it will do it faster than any other solution I have ever seen.


    The Box


    The first you notice when you pull it out of the box is that the construction of this device is unmistakably Lian-li.  The brushed aluminum finish and esthetics of the unit are outstanding with excellent attention to detail.  When you open the drive door you can quickly see that this thing was designed to keep things cool not only for the hard drives, but the overall unit as well as the built in controller.  When you look inside you see the 140mm fan which is positioned directly behind the hard drives themselves.  When you power on the unit, the air flow is stellar with enough air moving to handle even the hottest Caviar Black drives which great spacing for air flow in between drives.  As you would expect, the fan is almost silent despite moving a ton of air.






    To insert drives you do have to mount them in a bracket first.  I would have liked it better if they made it completely tool-less, however considering the market this playing in and that you could be moving this unit around, is probably not a show stopper.  Once inserted, the drives are locked in place by a small plastic slider clip which securely keeps drives from sliding out which helps as you toss this in your car and move it offsite.






    There are two ways of setting up your storage box.  The first is using their software which is no more than a JMicron utility that lets you configure the box with the drive/RAID configuration you need.  The software is very easy and straightforward but as I mentioned earlier, very limited.  It does RAID setup and it it does it well.  It will not however, support RAID expansion.  Depending on what you are using this for, that may or may not be a problem.  For me it was a non issue as I am using this for backup so if I needed to expand it, I could just pull out the drives, install larger drives, and rebuild the backup as I do not plan on using this as primary storage, after all, we are the home server community.  If you have an existing array of say 3 drives, you will need to either create a separate array or you delete the array and rebuild it with 5 drives.  This is not unique to this product and affects most of the products in the market segment.  What was interesting is that the array was built in about 8 secs with three drives.  I ran some speed tests, copied data to it, then I deleted the array, added two more drives, and recreated the array again it was ready to go in about 10 secs.  Pretty impressive for building an array.  As a side note, the software can be installed on any computer and once the unit has been configured it can be moved anywhere so you do not have to worry about installing stuff on your server.


    Also, if you do not want to install software at all or if for some reason you cannot install the software, there is a switch in the back that lets you set the drive configuration that you want.  After setting the desired configuration, pressing and holding the “activate” switch for 15 secs build and creates that array.

    USB 3.0 Performance


    One of the things that concerned me most when I first heard about this unit, is, would it perform.  I have tried and seen many of these storage boxes only to be disappointed with sub-standard performance.  I have no interest in spending money on a device that gets 10-15 megs/sec.  If I was going to use this box as expanded storage for my home server, than I wanted some real performance especially since it was on a USB 3 interface.  I am certainly happy to report that this device did not disappoint in terms of performance.  It exceeded my expectations for a device like this and rivaled the performance of most servers.  Transfers over the network were constant at ~104 Megs/sec with peaks of 115.  Transfer within the local machine appeared to be limited only by the machines ability to write and hovered between constantly above 100 Megs/sec.  As you can see from the benchmarks, write performance rivals some SSDs.  Overall, the performance of this device is stellar and in terms of server expansion, it is really the perfect match.  It is roughly 3-8x faster than NAS boxes such as the D-Link unit, Synology, or Drobo, and approximately 20-80% faster than USB 3 standalone drives.

    In short, this is a great device for the right application and the form and finish is stellar.  This unit is certainly not for everyone.  If you need a suite of utilities, direct network attachment, and a more robust drive expandability than you should not get this box.  If however you are looking for expanded storage or server backup, than look no further.  This unit will not disappoint.  If you believe what they claim on their website, it will accept drives up to 6T each so it should be a bit future proof.  When 3T drives become a bit more affordable, this will be a great match and give you 12T of storage/backup in a small form factor.

    I found the firmware is greyed out when attached by USB 3.0 or eSata to PC with no HDD installed. After installing HDD the firmware update option was available - though when I checked online the latest firmware was older than the one installed - so I did nothing. The latest driver R1.17.63.01 is available from Lian Li http://www.lian-li.com/v2/en/product/product06.ph... But the RAID managment tool will not download (I tried the EX-50 download for RAID Managment tool and this worked fine - It is the same version) I have tried the ex-503 with single HDD or Mirrored RAID but you are unable to have both single HDD and Mirrored RAID at the same time. I have 3TB Mirrored Drives and all works well - but... after 6 Hours of continual copying via eSata connection the EX-503 gave up and started beeping alot - Windows 7 x64 PRO repeatedly attached then dropped the HDD. I shut everything down PC and ex-503 and restarted and tried USB 3.0 and eSata with no joy. After coming back from work I tried again and continued the copy job with no issues ......so far - will keep you posted on outcome

    Nando, I'm not surprised about your experience. I think you did the right choice. In this moment I'm wondering about Lian-Li. It has a very nice product, but without some kind of support it's unuseful. After 3 RMA without any feedback, I'm moving all the files out of the RAID5. Luckly, I bought one hard disk for substitutions. The other RAID1 is full, but I'm using it to save what I can. I suspect that the REAL ORIGINE of my problems is the JMicron HW Raid Manager utility. Now I'm copying 1TB from Lian-Li to the the additional disk and JMicron Manager is off: seems going smooth. I had 2 problems: at 2TB of occupied space the RAID5 got offline (changed from USB3 to eSata and seemed to solve the problem). Another problem: RAID5 goes offline when I try to copy a 36GB file. Is it too big? :-O I have a degradeted RAID5 because LianLi doesn't like a disk: "PAGE 0 DAMAGE ERROR". Nowhere in Internet there is an explanation about this string! I made all the test on disk. The disk i perfect, but no way: LianLi EX-503B refused to add it again to the RAID5 chain. I put another NEW disk and there was a failure in rebuilding after 1%: so I'm copying all data out of EX-503B to other disks. I have a degradeted RAID5 and I'm praying that all could go fine.

    In my experience, you should not use h/w RAID outside of the enterprise because you are bound to a vendor which is not commiting to any SLA. Software RAID has come a long way and it's perfectly up to the task. Have any of you tried this unit for some time on a port multiplier config using LVM, VxVM or ZFS (whatever redundancy config you like)? Thanks,

    UPDATE Lian-Li solved my problem by the EX-503B substitution. It had a controller problem. Now I'm happy. Great performance: sustained 220MB/s in readind/writing with eSata controller . Regards

    Hi Luca, How do you mean Lian-Li solved your problem by the EX-503B substitution? Did they replace your EX-503 with a EX-503B because that would be the best result. I have been having issues trying to Raid 0 my 5 x 2Tb WD drives, it keeps erroring out or crashing when either creating the Raid 0 or once done when I try to copy the files back to my 10Tb drive it errors and I have to start all over again. If this isn't the case that Lian-Li actually helped you out, bugga and I'll just have to leave it as the 5 x 2Tb individual drives appearing in Windows. Unless anyone has a solution without having to buy another Raid enclosure. thanks regards David

    Hi David, I had EX-503B and they replaced with the same model. The error involved the raid5 configuration and often appeared while writing. It was a random error and thus very dangerous. I suspect it was a buggy controller. Hope could help you Regards

    • I throw this out every once in a while.  Is anyone interested in writing up "semi-formal" reviews here on the forums?  I say semi-formal because they don't have to be pro level, just a good attempt at telling the story about the gear.  Something you have purchased lately.  You don't have to go buy stuff, just incorporate what you have already have purchased.  Hit me up with any questions.  You never know where it will lead!

    • OneDrive Personal Vault and expandable storage
      Microsoft's OneDrive has a few new features and options worth pointing out.  Personal Vault and Expandable Storage.
      Personal Vault is a protected area in OneDrive that can only be accessed with a strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. 
      Personal Vault gives you an added layer of protection for your most important files, photos, and videos—for example, copies of documents such as your passport, driver’s license, or insurance information—should someone gain access to your account or device.
      Plus, this added security won’t slow you down. You can quickly access your important documents, photos, and files with confidence wherever you are, on your PC, OneDrive.com, or your mobile device.

      Beyond a second layer of identity verification, Personal Vault also includes the following security measures:
      Scan and shoot—Using the OneDrive app, you can scan documents or shoot photos directly into your Personal Vault, keeping them off less secure areas of your device, like your camera roll.
      Automatic locking—No need to worry about whether you left your Personal Vault or your files open—both will close and lock automatically after a period of inactivity.
      BitLocker encryption—On Windows 10 PCs, OneDrive automatically syncs your Personal Vault files to a BitLocker-encrypted area of your local hard drive.
      Restricted sharing—To prevent accidental sharing, files in Personal Vault and shared items moved into Personal Vault cannot be shared.
      Taken together, these security measures help ensure that Personal Vault files are not stored unprotected on your PC, and your files have additional protection, even if your Windows 10 PC or mobile device is lost, stolen, or someone gains access to it or to your account.
      Expandable Storage
      If you are and Office 365 Subscriber you get 1 TB of OneDrive storage space with all the other Office goodies like Word, Excel, etc.  I know personally that I have gone over the 1TB limit and have always wanted to be able to add additional storage to my account.  Now you can!

      Pick and option and keep on hoarding, errr, I mean saving! Cancel anytime, upgrade at any moment.

    • Ubiquiti adds new items to the Unifi Line including UAP Flex HD and the Unifi Dream machine
      Ubiquiti has been busy.  There area ton of new items to recently released and I'm going to share two of my favorites.
      The UAP Flex HD and the Unifi Dream machine. The Flex HD is a mouthful of descriptors like most of UI gear is.  It's a 2Ghz 2x2 MIMO, 5GHz 4x4 MU-MIMO, POE, Indoor/Outdoor, multi mount, mesh point that is no bigger than a can of Coke.

      You will still need the Unifi controller although you can configure it with basic functionality with the Unifi App.  I've always found it's best to configure with your controller and then use the app as an add-on.  There are several mounting options that include sitting it on a shelf! That is something that Unifi has not had before unless you count the ceiling AP I have awkwardly mounted placed on top of a few books.  It can be found on the Unifi store for $179.
      The Dream Machine is an altogether different beast that I hope lives up to its naming.  This is the gateway drug, for lack of a better term, to the Unifi world.  The starter kit.  It is an Access Point, Gigabit Switch, Security Gateway, and the Cloud Key all in one package.  The latter being the most significant as this is something that has deterred new users from getting started with Unifi.  Requiring new users to purchase a $100 item just to run the AP's has been somewhat of a roadblock in the past.  Granted, that is improving every year with the ability to run it in the cloud, on a NAS, a Pi, Docker, MacOS, and of course Windows, it is still a barricade to getting up and running when manufacturers such as Eero offer simplicity in an app.

      The switch includes 4 LAN Ports and 1 WAN port.  All of which are Gigabit and security services such as IPS are rated at Gigabit speed. It's $299 in the Unifi store but I'm unsure how nicely it will play with other Unifi gear.  This may be a nice "first AP" with its built in Cloud Key if you can add additional units or other Unifi access points.
