wonder the write endurance and the cost/capacities available, the temperature limit is not very good IMO and the wattage is similar not very good, but performance wise should be.
I wonder the read/write and IOPS let alone the pricing.....seems more and more ultra high performance SSD types come out but equally high $ per gb instead of finding a happy medium ground for "good enough performance and encroaching on the HDD cost per gb advantage currently enjoyed"
$0.30c per gb or so is "not bad" but when they are going up against $.14 per gb or worse they have a way to go ^.^
I want to see an SSD at 1tb or better for $200 including ship and tax for Canada (basically double the speed double the price makes sense to me better than current 2x the speed 1/2 the capacity for 2.25x or more price) ^.^
It's regular ddr4 memory with battery (supercap) backup. As such it's endurance is basically unlimited, and iops cease to matter as your limmited by the m.2 interface, and not the rams 1 million pluss iops limit. In short it's a hardware ram disk on a m.2 slot.
Capacity is low because DRAM is expensive and kinda power hungry in large quantities, and because log/journal drives don't need to be very large. The data stored on this kind of drive is expected to be very short-lived, becoming invalidated as soon as the transaction it is tracking is completed and fully written to traditional storage. It's not meant to be a general-purpose writeback cache for long-lived data.

U.2 interface actually, but the IOPS limits should be similar if not identical to M.2.fazalmajid - Friday, May 11, 2018 - link
Not sure about Canadian prices but the 2TB Micron 1100 SATA SSD is very attractive at USD 310.The Viking drive, like the DDRdrive before it, is meant primarily to use as a write log device for filesystems like ZFS that support this.

What are "regular NVDIMMs"?How are these related to the NVDIMMs based on XPoint memory that Intel plans to release next year?

Why such an extremely low capacity? Is this intended solely as a non volatile cache?Billy Tallis - Friday, May 11, 2018 - link

So why not use RAM on the server motherboard, and a UPS which can keep the server up for one minute?
