If you do much with computers, you might have heard of the home backup solution Drobo, which offers a redundant storage solution with striping and mirroring without any of the pain of a RAID array. Their cute devices take in four drives, use the space of one for redundancy, and give you protection against a single drive failure.
I wondered how fast it actually is, so I ran HD Tune, which measures the read speed of the drive:
On average, you’ll get 16MB/s out of the drobo, which is equivalent to probably half the speed of any of the drives you put into your Drobo. Maximum PC has a review in which the tried a Drobo with 1-4 drives, and they got an even 15.5MB/s in each configuration.
Update: I have several seagate drives in my Drobo, which come by default with a jumper limiting them to SATA I (150 mbs). After I removed the jumper so they could use the faster SATA II, benchmarks gave me an average read speed of 16.3 MB/s. Reports indicate that the write speed may be faster, but I haven’t confirmed this.
Update: On Windows 7, and using the latest in firmware, I get 19.3MB/s average rate, 24ms average access time. On my other Drobo, I get 20.1 MB/s and 28ms access time. I can’t say whether it’s windows or the latest firmware, but it’s nice things are getting faster!
