Good price for a 6TB drive from pretty much the only hard drive manufacturer I trust these days.
$50 cheaper than the best price on static ice
The price is $320 + $30.97 shipping. Get 2 drives and shipping is $43.81.
Get 3 drives and pay GST - so don't do that.
2.65% cashback for newegg at topcashback also (don't think the $10 referral bonus is running at the moment sadly).
Really, really good NAS HDDs right there.
I've got two of the 4TB models myself. If you don't need 6TB drives, get yourself the 4TB models from MSY for $245. Cheapest price by miles.
The Deskstar NAS HDDs have rotational vibration sensors, 1 million hour MBTFs and despite having 7200RPM spindle speeds, my two Desktar NAS HDDs are quieter than other 5400RPM drives and hit 34C at the hottest.
The TLER/CCTL time-out delay is also configurable via Smartmontools; these are true enterprise-class HDDs (unlike the WD Reds) that are around $60-80 dollars cheaper than the equivalent-sized variants of the WD RE/SE, HGST UltraStar or Seagate Enterprise series.
