Do all these SSD drives feature the some powerloss tolerance? One of the main reasons for choosing certain Intel drives was their combination of reasonable, but more importantly, consistent performance, while being fully crash safe and durable and still have an acceptabele price/capacity. (Safe, affordable but boring 😉)

Why is optane so slow? The only thing it's good at is doing random. Intel marketed the crap out of it since 2015. It was supposed to be "a revolutionary" product. A few years later and I don't see the insentive to buy this product, especially since you have a new (potentially worse) system in order to use optane?

Not buying Intel ssd again.. first 600p was mostly not working (device disappearing suddenly), the replacement had serious issues corrupting file systems ( https://bugzilla.redhat.com/show_bug.cgi?id=1402533 ). It's since fixed with firmware update, but the amount of headache caused by it, not trusting to their drives anymore, did they test it at all before releasing..

It's also another talking point to sell Z chipsets. Makes me think of people clamoring for more and more PCIe lanes - I don't think you'll need them, I'd rather have 4x storage lanes multiplexed to 8x or 16x lanes. Or more 2x slots and 2x SSDs - I would hardly care about this 760p being "crippled" to 2GB/s

For example: if i remove a file the simple way, for how long the SSD will keep my data and what is the potential for removed data to be recovered. I mean an SSD that can write 300MBps but the removed data are destroyed within month is a thousand times better than one that can write 500MBps but destroys removed data in a year or never. You should refer to technologies like that in your next article.
The only reliable way to keep your data secure and prevent unwanted access is to encrypt it. Everything else is about as useful as closing your eyes.

I just ran this test for my Ryzen 1800X + Samsung 960 EVO NVMe but realized after the run the temperatures were missing. What is actually the dependency for monitoring the temperature of an NVMe drive for PTS, is that nvme-cli?
Does aynone knows how to run the test profile again but now using another drive of the same machine, is that by changing the environment variable PTS_TEST_INSTALL_ROOT_PATH to the relevant disks?

Where it shines is: awesomely low access times, bit-addressability (in contrast to traditional which has to hack away in the controller to extract performance out of the page-based NAND) and consistency in performance (https://img.purch.com/r/600x450/aHR0...dlMDYxLnBuZw==).
Bear in mind that this is the first generation of this product that has to compete against a well established technology (NAND-based SSDs) that had it's own problems in the beginning
For a newcomer it's doing great. I'm looking forward to next generations of this product.

Have you never heard about wear leveling? SSDs are not actually removing data when you tell them to do so. You'd need to overwrite whole drive few times to be sure, or ask drive to drop encryption key if it has internal encryption.
There are some interesting papers on that subject.

Optane is not slow, in fact it's the fastest SSD you can get. It's just that it's very expensive to get the proper, multi-channel version (the 900P). This product is not for normal consumers since the differences between it and a NAND SSD are not really that big, however it is noticeable even while casually using Windows.

July 2015:
Intel and Micron today unveiled their all-new memory technology called 3D XPoint (pronounced "cross-point"). This is a new class of memory that can be used both as system memory as well as nonvolatile storage. In other words, 3D XPoint can be used to replace both a computer's RAM and its solid-state drive (SSD).
The companies claim that 3D XPoint is a major breakthrough in memory process technology, the first new memory category since the introduction of NAND flash in 1989. It's said to be extremely fast and durable, up to 1,000 times faster (both in read and write speeds), and it will have higher endurance than existing NAND Flash memory currently being used in SSDs. What's more, it also has as much as 10 times greater density, leading to much more storage capacity in the same physical space, while remaining as energy efficient and affordable as existing NAND flash memory.
