I had a second decent look at this topic
while NVMe and three million IOPS are gift from heaven,
there are some points I overlooked :
- Patrick has tested Intel 3320. For read application, it's very nice - kicks about 350k random 4kB IOPS. I will talk 3520 below, different model.
- for writes, it's a tragedy. Well maybe not that much, 22k random 4kB IOPS here according to Intel spec. My floppy disk is almost as fast
- endurance : 0.3 DWPD is by far not enough for me, I don't know about other guys. That's 700GB written a day for largest 2TB model. Uch.
- last but not least : price. 0.50$/GB is pretty nice, ESPECIALLY for enterprise customers paying $10/GB today, but you know what ?
I checked stores around me. Here in mid-Europe we usually have higher prices in EUR than United States have in USD. Exchange rate is about 1.12 USD/EUR, so 1120 dollars is 1000 eur. Look what I found easily :
Intel P3520 - well this is better model than P3320 discussed here, performance and endurance-wise !! And still :

Those prices
INCLUDE 21% value added tax so netto prices are around 875eur == about 980 dollars. Well considering this is END-USER PRICE [!!!] without any datacenter/volume discount, 0.50$/GB for P3320 does NOT look that good anymore to me
apologies for peeing against the wind, it's something inside of me that likes to look for flaws in what others say. These are just my findings which need very decent investigation.
P3520 has better write performance (26k IOPS versus 22k IOPS of P3320, yes small difference but still a difference of almost 20% !). I believe this has 0.7 DWPD endurance but please don't quote (this is more than twice as much as P3320 has). Intel says 2490TBW for 2TB model, that is 2490 / 5 years / 365 days / 2TB capacity = 0.7DWPD for 5 years according to my math.
I can't find any single characteristics where P3520 would be worse than P3320. I haven't looked at power consumption but I don't expect too much difference there, if any.
What's the price of P3520 there, guys ? What am I missing or overlooking ? There is no discussion these CHEAP and still pretty potent NVMe drives in 2.5" format are the standard tier in 2018. Intel Optane will be the front tier as it seems today. Spinning HDDs cold storage. Million IOPS for everyone.
Bring it on !
