If you really really want it asap (and live in EU) you can get a few slightly overpriced ones from ebay (from the launch event [-StarCitizen code]) ;)

I got my 280G on its release day. The performance is pretty good. planning to buy two more.

O_DIRECT supported on this platform for open_datasync and open_sync.

Compare file sync methods using one 8kB write:

(This is designed to compare the cost of writing 16kB in different write
open_sync sizes.)

Test if fsync on non-write file descriptor is honored:
(If the times are similar, fsync() can sync data written on a different

Blimey! 34082 iops in pg_test_fsync is just friggin insane!!! Thats 35 times!!!! more than Samsung SM961
sadly I've never seen the pg_test_fsync results on P4800x. what really interests me is the performance gap between 900p and P4800x.

Ordered a 280gb from newEgg today, fingers crossed it comes next week :) Said in-stock, we'll see :)

Sadly Limit was only 1 :(

So much for Newegg's "notify when in stock" feature. Thanks for the heads up.

I was able to sign up for <<BACKORDER>> status at Newegg last night. They just charged my credit card and sent me a FedEx tracking number. :) (Intel Optane SSD 900P (280GB, AIC PCIe 3.0 x4, 20nm, 3D XPoint)

PS: ServeTheHome is definitely dangerous to my finances. (2 kids in college, one more in high school and one in parochial school, I should know better....but heck I turn 50 in a couple of weeks and I'm worth it.)

I'll probably use mine for a heavy write cache since it is pretty small for anything else.
