CrashPlan Saves The Day

Leave a comment

I had a pretty big data disaster the other day.  It was totally my fault, but fortunately I’d put safety nets in place so that my carefree ways didn’t cause me too much pain.  Basically I lost an afternoon of time where I would otherwise have been able to play the last mission in Starcraft 2.  The short version is my RAID was corrupted, my Dropbox picked up stale changes and screwed up all my machines, my Windows gaming PC wouldn’t boot, my home server didn’t cooperate, but CrashPlan saved the day.

(I meant to post this back when it happened, around November 2, but I just got to doing it now.  The point is that CrashPlan has been promoted in my opinion to “indispensable”.)

Drobo S vs. Synology 1511+ Performance Numbers

11 Comments

Since I got my Drobo S back up and running with a new power supply, I thought I’d put up some quick performance numbers.  The tests are just copying some DVD images back & forth using Windows Explorer and timing on a stopwatch.

Synology via Gigabit Ethernet

Read: 3920357376B in 53 files, 2 folders from Synology to my Desktop on my Shift PC: 67 seconds = 58512797 B/s = 468.10 megabits / s = 58.5 MB/s (just to put all the units out there in case anybody’s confused)

Write: 3921112106B (same as the test below from the same spot) to Synology: 69 seconds = 56.8MB/s

Drobo S via eSATA

3921112106B in 58 files, 2 folders from Drobo-S to same spot on Shift PC: 49 seconds = 80022696 B/s = 640.18 megabits / s = 80.0 MB/s.

Write: 3921112106B to Synology: 53s = 74 MB/s.

Drobo S wins soundly.  Here’s the summary, again:

  • Drobo S via eSATA: 80.0 MB/s read, 74 MB/s write
  • Synology 1511+ via Gig-E: 58.5 MB/s read, 56.8 MB/s write

Anybody think I can tweak settings to get the Synology to go faster?  Let me know what they are.
