I'm about to replace my faulty Qnap TS-239 Pro that just died on me, and I want something that provides me with even better performance! As I've got Link Aggregation enabled, and use CAT7 cabling and also have Intel Pro/1000 ET Dual adapter with Link Aggregation on my desktop computer it's the NAS that slows down my speeds and not my network. I was running the TS-239 with 2x WD10EADS featuring EXT3 and got a maximum rating of 40-50mbps in Windows7. Now I want to increase those numbers a bit, the first obvious thing to do is to replace the Green Power hard drive with something faster, that's where my new WD Black Edition 2TB drives comes in, those combined with better hardware and RAID5 instead of RAID0 should increase the overall performance quite a bit? But will still the hardware of the Qnap TS-459 / Synology DS1010+ still be the bottleneck? Slowing down the Black Edition hard drives? Or will I be able to fully utilize it's mayhem? The Qnap TS-459 and the Synology DS1010+ seems to feature pretty much the same hardware and power? They both have 1GiB RAM, they both use the 1.66GHz Dual Core Atom CPU, the only difference seems to be the DS1010+ featuring 5-drives and the TS-459 "only" 4-drives? But then again, at least here in Norway the TS-459 goes for a little bit cheaper than the DS1010+ and I don't really need more than 4-drives. When it comes to the software / firmware part both Qnap and Synology seems to run almost the same things these days? The UI pretty much looks identical, and they have about the same features? Though I've heard that people claims the Synology software to be superior in some ways? On the other hand Qnap have a advantage in full EXT4 support, which the Synology firmware for some awkward reason still lacks? So which one would provide me with the best performance? The Qnap TS-459 Pro with it's EXT4 support and software, or the Synology DS1010+ with it's 5-drivers and slightly higher price tag?
