Today we're comparing the Thecus N5550 that costs around $560 to the QNAP TS-860 Pro that costs double that amount and holds eight drives compared to the N5550's five. On the surface it doesn't sound like a fair comparison, but the Thecus N5550 performs so well the needed a product with a little more muscle to compare it to.
With five bays, the Thecus N5550 works best with RAID 5, but RAID 6 is still an option. All of our tests are with five drives installed in the N5550 except RAID 10, a architecture that needs en even number of drives, so RAID 10 on the N5550 is with four drives. The QNAP TS-869 Pro runs eight drives in all tests.
In the HD Playback tests we scale through one, two and four video files coming from the NAS. With just a single drive installed we see the Thecus N5550 showing it's high performance and pushes the data out 10MB/s faster than the QNAP. The Thecus unit continues to outperform the QNAP until we get to RAID 5. At RAID 5 things start to level out, but at RAID 6 the QNAP unit takes the lead.
