The lineup will be available on December 16th starting at a modest $150 for a 1TB model, climbing to $300 for a 2TB drive and peaking at a relatively reasonable $600 for a 4TB version. You could use one to store all your data without breaking the bank, rather than having to use it as a boot drive.
You may want to be careful before rushing to buy one for your gaming rig, though. While the sequential data read speeds are good for the money at 550MB/s, the write speeds are another story. AnandTech pointed out that the claimed 520MB/s sequential write speed only holds when you're using the cache. Like other high-capacity-low-price SSDs, the sustainable speeds fall significantly when you don't have the luxury of that cache, ranging from 80MB/s on the 1TB model to 160MB/s on the 2TB and 4TB editions. A discounted 860 EVO might be more competitive than the QVO. With that said, we wouldn't expect the QVO to stay at official prices forever. A drop in street prices could make this the value champ for people more interested in having a do-it-all drive than the fastest possible performance.
