    The one thing about Drobo that kept me on the brand was the no-bullshit drive swapping. No need to go into a UI to do it, just remove one drive and put a new one in. You can ignore the size and just buy whatever's most cost effective at the time, and it just works. Amazing stuff.
    It's good to hear that Synology now lets you mix drive sizes - somehow that info is _really hard to find_ on Synology's own marketing materials.
    It sounds like adding a drive is still janky on Synology though, requiring me to go into the UI to manually add it after inserting it. That kind of sucks, but it's not like there is any better option anymore.

      A lot of that drive swapping stuff is what lead to these things being somewhat unreliable. People would mix and match all sorts of drives of different sizes and specs, the Drobo would try its best to fit it in, but in the end it would just lead to problems when some drives would start to bottleneck or run out of storage. It's a great idea but realistically it's a lot more stable to use drives of the same spec. It becomes really clear how problems started to arise when you see people mixing SMR drives with CMR drives, and of different brands and speeds, it's no wonder things would go wrong.

      @@danglassphoto It has worked out very well for me, much faster and capable. Basically the Prime Day deal, plus the processor. I wanted to use it for Plex and the 1522 is slightly less capable according to the reviews.

    I have to say that I had to go through some growing pains to get where I am today in terms of external storage solutions, and I'd like to share that with you and your audience. I had already made the switch to Mac by the time I felt the need for some sort of external back up. Flash drives at that time only offered about 6 or 8 gig max and I wanted more. My first attempt was the HP home server. It never really seemed to live up to it's claim to be compatable with Mac OS. That's when I moved on to the Drobo 4 bay back up storage. I was content with Drobo until I had to relocate to China (for my Wife). Drobo was just to bulky to take along so I gave it to my brother. Next can the Mac Time capsule, which again was more of external storage than a server.
    I eventually outgrew that as well as my movie & music library grew. That's when I discovered Synology through a You tube video recommendation. I have to say that it was probably the best decision I ever made in terms of external data storage solutions. I hope this helps any of your subscribers to make their decision on what to buy next.

      The problem is when your Drobos fill up, it's all too common to have them shit the bed with no hope of recovering your data. I've had this happen on an 8 bay Drobo and a 4 bay Drobo. Here's hoping that you have a better storage solution by now.

    I managed to get a great deal on a 1621+ earlier this year from Amazon Warrhouse (Damaged Box - Unit itself was brand new!) but had to wait a few months to find a deal on new hard drives (Eventually picked up 4x 16TB Seagate Exos). I reached the 16TB limit on my Drobo 5N and didn’t see the point of copying my data off to an external drive/drives only to reformat the Drobo disk pack to remove the limit. The network copy performance difference alone has made the upgrade well worth it and I now have a NAS with better redundancy, in SHR2 and data security with Snapshot Replication along with plenty of expansion for additional drives. My Time Machine backups for my Mac are also working much more reliably as well.

  • @CraigLafferty
    @CraigLafferty 2 ปีที่แล้ว +2

    Yep! I have a Drobo 5D and was looking to go to a NAS 8 months ago and saw the writing on the wall. It was your videos and help that steered me to Synology. I really, really liked the Drobo platform and it is a shame that this is happening, but I'm very happy with my Synology.

  • @kirkmays2125
    @kirkmays2125 2 ปีที่แล้ว +3

    I thought until now that DROBO had closed and was out of business. I tried, unsuccessfully, in contacting them approximately six months ago.
    First off let me preface with the fact that I’m not a computer literate person and most of the information you give on your videos is over my head. The problem I have is with my 5d Thunderbolt. My Drobo stopped powering up so I replaced the power brick and it lasted for a day working perfectly fine, then the next morning it would no longer power up. A friend of mine looked at it and found some circuitry that was burnt. So while he was trying to repair the circuitry, I purchased an additional D5 used from eBay.
    My thinking was I could load my drives in it, but before I did that I watched some TH-cam videos. The information that stopped me from loading the drives, was that the video said that if it didn’t have the same firmware, that it would automatically reformat the drives and that I could lose all my data. So I looked into having my data recovered. The prices I was given ranged from $2500.00 to $8000.00, so that wasn’t a sound option. At that time I didn’t have the ability to check what version of software I had, because when I started the process of switching Drobos, I had an IT guy come over to do some maintenance and he updated my Drobo dashboard while getting ready to setup the new one I had bought from eBay.
    I got the one back my friend fixed that had the burnt circuitry. I never powered it up because he was not convinced it was completely repaired. So, my question to you is, is it true that it will re-format if I plug these drives in to the new one, and once it re-formats the drives, will I lose all of my photos? Do you have any suggestions on how I should proceed?
    I left out that I have a Synology 1621+ coming in the next day or so, with hope that I’ll be able to load my drives from the original Drobo after I retrieve my data from them. I also have 2 new drives I bought for the newer Drobo that I haven’t used yet.
    If you or anyone knows what I should do to get my data recovered more affordability, I’d truly appreciate it.

    • @GregoryCunningham
      @GregoryCunningham 2 ปีที่แล้ว +1

      Do you not have backups? If not, *please* use this as a life lesson. Always have at least 1 backup, if not 2. Having said that, if you purchase the same model DROBO, with the same firmware as your dead unit. And load the drives in the same order they are in your current unit. You should be able to recover your data. Having said that, do not take my word for it, do as much research as possible before even attempting this recovery.

    • @kirkmays2125
      @kirkmays2125 2 ปีที่แล้ว +1

      Drobo got back to me by way of email they said as long as I have updated the new Drobo I could load the drives in to it in the same order as they were in the old one making sure it was off and I should be fine.

  • @johnb4467
    @johnb4467 2 ปีที่แล้ว +1

    It's funny that I found your video right now -- as earlier today I just put in an order for a Synology DS1821+ to replace my 9+ year old Drobo 5N that has been running 24/7 all these years. The thing is still running like a champ, but it's getting to an age where I'm uncomfortable knowing that it could die at any time & I'd have no options in securing a new unit to pop the drives into. I literally didn't know that they filed Chapter 11 until last night, as I started researching if they had any newer offerings & noted everything was out of stock and started reading.
    Hoping I can get accustomed to the Synology world. I'm pretty tech-savvy, but definitely appreciated Drobo's simplicity. I'm noting some slimmer drive compatibility for the DS1821+ currently, but am hoping that's just because it's so 'new' out the gate. I had picked up a 16TB Ironwolf Pro, which according to their list...isn't compatible?!
    Thank you for your video -- and tribute at the end -- to Drobo's line!

    Damn, I'm glad I came across this video. I have been running a 5 bay Drobo RAID device on a Mac for about 10 years and they tend to fail every 3 years. As you know, you can't get the data off the drives if the Drobo fails so you have to buy a replacement Drobo. It's only because my Thunderbolt 2 to Thunderbolt 3 adapter started failing that I went to see if Drobo were selling the 5 bay RAID with Thunderbolt 3 connections, that's when I found out they'd folded.
    So now I'm looking around for a suitable replacement, ideally with hardware RAID.

  • @Sevenfeet0
    @Sevenfeet0 2 ปีที่แล้ว +1

    I had two Drobos in production....an ancient Gen 2 (USB/Fireware 4-bay) and a 5D3 Thunderbolt/USB3 unit purchased 4.5 years ago. But it became apparent in the last year that Drobo was on its way to failure as a company so I invested in a QNAP TVS-h1688x, which is a huge purchase but it was designed to replaced the Drobos and two other servers in my basement. So far the QNAP has worked well although the software (QuTS Hero 5) is a little buggy and we've had to dodge the security issues with QNAP in the past year (I do not have my unit facing the internet in any way). The 5D3 is still a good unit and I may still use it for backups of the QNAP. One thing I did do for backups was invest in a QWC Thunderbay 8. I think when you do a video about Drobo DAS owners, you must talk about the Thunderbay line since it makes a lot of sense for many of Drobos old customers which are largely professional and prosumer Mac users.

  • @goodeguy16
    @goodeguy16 2 ปีที่แล้ว

    YES!!! I need to get off my Drobo 5D3. I've been looking at the QNAP TVS-672XT and QNAP TS-h973AX...but I believe a newer version(s) might be coming out very soon, so I'm willing to wait a bit, but I do need to get of the Drobo very soon. I do 4K video editing and photography. Looking at only QNAP after looking at others. I saw a lot of QNAP video editing TH-cam videos and I believe QNAP is the system for me, but again, I believe newer systems will be coming very soon and I want to take advantage of that and maybe Thunderbolt 4 on the higher end models, even though they have it for the lower end. What do you think? Am I doing the right thing to wait a bit? My Drobo is running fine, but I need faster and Drobo might or might not have a future.

    @thomasbriggs4718 2 ปีที่แล้ว

    I’ve had two Drobos over the last decade, as backup to a file server. I replaced the server with a Synology NAS. The second drobo lost its Ethernet capability so I opted for an expansion to the Synology box. So now I have two volumes that are mirrored. Each volume would survive a single disk failure, so I think I am safe.

    @andredevillier3244 ปีที่แล้ว

    May be a dumb question but here goes... I've had a Drobo 5n for more years than I can count. 5x 4TB WD Red drives, but only about 4 TB of stuff on them. I would like to be able to re-use the drives if possible. Would they have to be re-formatted for Synology or other NAS? I seem to remember with Drobo, you can just pull out a bad drive (in fact I've done it) and the data will re-sort itself across the remaining four. If I do that, then could I serially add 2 or 3 drives to the new NAS and re-format them if necessary, then copy all the data across, then add the last drives as extra storage on the new NAS?

Can I simply take out drives out of the DROBO and put them in the Synology. Anyone have an answer?

    @zavatone 10 หลายเดือนก่อน

    I tested Drobos back in 2008 and still have one of the 4 bay Thunderbolt 2 Drobos in use. DO NOT GO THERE. Regarding the 4 bay model, a base Drobo's drive speed is the average speed of your drives DIVIDED BY the number of drives you have. It's monumentally slower unless there is an SSD getting data first in the chain as opposed to your 4 mechanical drives. It doesn't matter if it's on a fast connection. A 4 drive Drobo is SLOOOOW since the data write completes after it's been written to all drives it thinks it needs to write to. Yes, I tested this and it is as slow as I say, even if it only duplicates the data over some of the drives. ALSO, I tested an 8 bay Drobo to see how it operates if I fill the drive up and then try to see how it handles that condition. It simply fails miserably. While the hot swapping of drives in a Drobo is nice (and I have taken advantage of this multiple times), if you add more data than 1/2 of the total capacity, at some point, Drobo will shit the bed and so will your data.

    Dear Valued Drobo Customer, Thank you for entrusting Drobo with your critical data. We have found that the upcoming macOS Ventura update is currently incompatible with Drobo. We cannot guarantee compatibility with future OS updates. Therefore, if you are planning on upgrading your macOS we highly recommend backing up data that resides on your Drobo to mitigate any unknown impacts of incompatibility.

The ASUSTOR has very fast startup and shutdown time (under 3 minutes) If I had to buy a turnkey unit it would be ASUSTOR. QNAP uses great hardware, but their OS and Apps is another story. The last 6 years has been way too much trouble.I will point out that I used them just for storage.

    It's not looking good with Drobo!...
    I have just discovered that Drobo Dashboard is no longer able to install any DroboApps on my 5N. It appears the site the repositories are stored on has gone away (updates.drobo.com), which was confirmed by the response I got from a support request..."The DroboApps Server 'updates.drobo.com' is currently down. Engineering is aware, no indication as to when the issue will be resolved." To make it worse, the DroboApps SDK was also stored on that server, so I am unable to cross-compile my own binaries from source. So I think all DroboApps are now dead... unless that subdomain miraculously reappears. If anyone is running DroboApps, don't uninstall any of them as you won't be able to re-install! (If anyone knows of a cached binary for the apache2.4.37 webserver for a 5N, I'd really like to know where to find it!).
    I wish QNAP could support a BeyondRAID-like diskpack of unequal sized drives like Synology do now. I want that hardware, but would loose a significant amount of storage with QNAP as my drives are 2,3 & 4TB! I've been a Drobo user since the original 4-bay unit and DroboShare, but looks like I'll need to move before any hardware fails and I loose all my data.
