QNAP TS-209 Pro II NAS
Feb 24th, 2009 | By SimonJust a Bunch of Disks (JBOD) or Linear Disk Volume is the most basic configuration possible. It’s similar to installing a bunch of hard drives on to your PC and allowing for network access. We can see the read transfer rates hovers mainly in the 15-20 MB/s range with slightly faster results for smaller files. There’s a clear advantage to having a large record size. In the writing rates, it looks like we spend most of the time around 5-10MB/s with the occasional cross over to the 10-15MB/s range with the larger record size.
RAID 0 is the most popular amongst enthusiasts. RAID 0 splits data across usually two and occasionally more disks. Because of this, RAID 0, like JBOD is left without data redundancy. With each additional disk attached to a RAID 0 setup, failure rate is increased. Any individual disk failing in a RAID 0 setup causes the entire array to fail. I don’t recommend RAID 0 for anyone with information they wouldn’t want to lose. The TS-209 Pro II hangs out at the 20 MB/s ball park for reading and anywhere in the 5-12MB/s zone for writing.
RAID 1 mirrors your hard drives so each stores the same information. If one drive fails, the second drive will still have your data. This test was only conducted with two drives in use. As you can expect, the performance will decrease to allow for mirroring. With the effects of mirroring, I’m not surprised to see the read rates to be slightly slower and mainly in the 15MB/s range. The same effect is felt with the write results as we’re generally under the 10MB/s mark.
The single disk volume is exactly what the names says, it creates a single disk volume. It’s perfect if you only have one hard drive currently installed but intend on installing a second sometime in the future. It provides the highest read results with the speed being in the high teens but the write performance still hovers around the 10-15MB/s.
