After I was able to experience through a WD My Book 4TB that even an external disk with 145 MB / s while working virtually silently, I looked at the old 320GB disk with different eyes. That would not turn out well for our long-standing relationship, even though I have so long entrusted to her all my secrets.
Now, why is the "old" no longer good enough for me?
Well, it just sucks a little, because, in spite of a Scythe Himuro SCH-1000 is still too loud and just now coming up against their limits in terms of capacity.
Why do I need so much space?
Actually there are all my data on the network and be there s also adopted mostly with 80-100 MB / and delivered. But for some things that's just too slow. On the one hand I deal with a lot of video material, on the other hand I use multiple virtual machines in Oracle Virtual Box, grow their virtual disks with the times strong and of course, require permanent access. You could, of course, with a second win awesome SSD speed, but the SSDs are still too expensive and for a virtual machine, it does quite a hard disk. But much faster than the previous 60 MB / s, it should be just now.
Towards fatal So this time away from WD Green and Red, who populate my server for black Femme, the WD Black!

The results of CrystalDiskMark, HD Tune and ATTO Disk Benchmark you see at the customer images.
Yes, the access time of the "little ones" lags with almost 16ms behind those big black brothers afterwards, but so far I am very satisfied with the services and will have a few items "perceived" values here, if our relationship was something deeper.
Clear a WD Black is more expensive than Red, Green, Blue and Purple, but currently only a measly 10 euro more (the Green and Blue), I like to invest for a securitized more with exchange and return policy.
Delivery by Amazon with 2-day express. In the box with packing material to find the original WD packaging with a HDD in antistatic film as well as molded parts made of HDPE (high density polyethylene). For that reason alone always order from Amazon itself.
UPDATE:
After intensive use, and currently 60% fill level I measured it again. The read and write rate drops to about 150 MB / s.
Unfortunately, Amazon is unable customer images get back together (indictment!), So I hang here the current value with.
