Thank you for this review. I am in the market for a NAS and HDDs to store my BDs on and this NAS might be a candidate. So I would very much appreciate it if you would ask Qnap to answer some questions and also make more measurements on the TS-412 with the home entertainment application in mind.
I want to understand the TS-412's characteristics in RAID 5 mode. More particularly, I would like to know its characteristics in RAID 5 when packed with four WD30EZRX drives. This NAS system configuration would allow storage of approximately 250 BDs for about $1150, here in the USA, a cost of $4.00 each to store'em and serve'em. Damn high, but as good as we can expect until 4 TB drives come on to drive the 3 TB HDD price down, which is being delayed by TI-Miho's earthquake troubles. This compares to $5.00 per BD if using the smaller 2 TB drives.
By the way, for me to spring for the HD-412, $600 in HDDs and $80 for a used APC UPS, Qnap would have to belly up to the bar and say expressly and absolutely officially that the WD30EZRX HDDs would work in the TS-412 in RAID 5 mode. Will they do that or will they slither back into their TW shell? Maybe you can get the answer. I won't even start if I have to use 5-platter, 7200 RPM HDDs to reach 3 TB per HDD. I'll bet you could talk WD into providing you the drives for testing. After all, this could be a pretty good size market for WD's mammoth drives. And they could leverage it into a leg up on Seagate which is currently offering only 5-platter 7200 RPM 3 TBs.
Anyway, cutting to the chase, the following technical issues are very important to me and I would much appreciate your effort in measuring:
1. The number of BD MKV streams that the TS-412 will simultaneously serve using four WD30EZRX HDDs in RAID 5 on a wired 1 Gbps LAN with Win 7 clients running VLC Player.
2. The amount of AC power drawn by the TS-412 when operating under the conditions of question 1.
3. The amount of AC power drawn by the TS-412 when serving a single BD MKV stream over a 1 Gbps LAN to a Win 7 client running VLC Player.
4. The amount of AC power drawn by the TS-412 when serving no BD MKV streams.
5. The amount of noise the TS-412 makes when serving its maximum number of BD MKV streams.
6. The amount of noise the TS-412 makes when serving a single BD MKV stream.
7. The amount of noise the TS-412 makes when serving no BD MKV streams.
