RE: New Drobo 5N2
I don't see any published specs, but the big question is: can it do on the fly Plex transcoding?

RE: New Drobo 5N2
I got this from a sales rep yesterday...

Up to 190 MB/s Read (average)
up to 197MB/s Write (average)

Approximately 2x performance increase when compared to the 5N
Approximately 7x performance increase when compared to the FS

CPU/RAM - Marvell Armada XP quad core running at 1.6 GHz, 2GB RAM.

RE: New Drobo 5N2
Thanks for the info. I just ordered the 5N2 because they gave me $50 off. I was waiting for a new NAS because the 5N wasn't fast enough. If the 5N2 can get close to 200MB read and write that would be nice. I wished they would have used M.2 slot SATA instead of mSATA for the "boost drive".

RE: New Drobo 5N2
thats pretty quick Smile
(especially when compared to some values in my sig with old computer) Smile

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)

Wait..... isn't this the specs for the original 5N?

RE: New Drobo 5N2
From Drobo...
The original 5N has a 1.2 GHz processor and slower RAM. It is the same familiar of processor which is where the confusion may have come from. The Read/Write speeds for the original 5N average anywhere between 90-115MB/s under ideal circumstances as well.

RE: New Drobo 5N2
Thank you for the info AzDragonLord!

I don't see it as much of a spec bump to make an upgrade worthwhile for me, I was hoping for more RAM, like 4GB since I run a lot of apps. My media 5N runs with about 200MB+- of RAM free.

I wonder if migrating a 64TB 5N Disk Pack to a 5N2 will see any reduction in speed like the 16TB Disk Packs do.

RE: New Drobo 5N2
I agree it doesn't seem like a large upgrade beyond what I already have.

RE: New Drobo 5N2
So, in *over four years*, here's what we just got:
1) A slightly faster processor.
2) Dual Gigabit ports (available since the DroboPro FS in 2010).

No ability to expand the chassis when we run out of drive bays, especially important since individual drive capacity isn't growing like it used to. No ability to hook a drive directly to the Drobo, making backups an enormous pain in the ***. Still an mSATA bay, even though the industry moved to M2 years ago, let alone newer blade form factors and NVMe. Twice as fast... "under ideal circumstances". I've watched those "ideal circumstances" crumble over years of having my 5N to the point where I dread any significant movement of data on or off it. Almost certainly still ARM-based, so no transcoding, nothing like QuickSync, and generally anemic performance when running a bunch of apps.

I've never seen a stronger message to go somewhere else. (Okay, maybe the rampant forum spam is another sign that things are not well at Drobo.)

Drobo 5N | 250GB Samsung 850 EVO mSATA | 2 x 4TB Seagate, 3 x 4TB Hitachi | FS/EXT3 diskpack
Peak performance >100MBps read/write (based on FS disk pack, no jumbo frames, no SSD)
DroboPorts: Plex, Transmission, OpenSSH, NFS, nano, screen, bash
