Q: for the read speed it says this. < 10 us how fast is this speed in MBS?

Read Latency and Write Latency refer to how fast the drive begins to read or write data from receiving the instruction to do so. In this case, it is less than 10 micro seconds which is 0.00001 seconds. A smaller latency is better.

Question 1

Is it possible to have 2 of these installed in a machine if I wanted 2TB of space?

Accepted Answer

I have 2 installed and am running them in Raid 0 for a very fast 2TB setup.  I'm using a threadripper motherboard so this is AMD's raid.  To get it to work you must disable CSM/Legacy mode in the bios or the choices to set up the raid don't show.  Set CSM mode off, save setup and reboot, then you'll find the raid setup choices as documented in the manual.  This is what I had to do on my Gigabyte Designare x399 ex.  So I can't speak for other systems, but I suspect on an AMD motherboard you'll run into something similar as to what I had to do.  Then just install your OS with the F6 drivers ready on your install stick and you'll be good to go with a 2tb raid 0 array as your boot drive.  As always, make sure you have good backup strategies especially with Raid 0 .  I'm using Macrium Reflect to USB external drives I swap.  (Reflect Free works too but I have the paid version for some of the other features)

Question 2

Will with work in my ASUS P8Z77-V?

Accepted Answer

Yes probably, but.  The card needs a PCIe 3 slot.  Your motherboard has 2 of those for 2 graphics cards.  If you are NOT running 2 graphics cards then yes it will probably work in the second graphics card slot.  You will probably not get very good performance out of it because an 8 year old motherboard and BIOS probably does not support  things like NVMe.
I would recommend buying a new motherboard to put this in.  Especially considering the cost of this.

Question 3

Half height? Does this fit in a 4u server pci slot?

Accepted Answer

Intel Optane SSD 905P is designed for desktop. Warranty is voided if used in a multi-user, multi-CPU data center environment.

Question 4

Is there any reason to get this over something like a Samsung 850 (Evo or Pro)? Any features I am missing, because it seems to be roughly the same speed for about 4x the price.

Accepted Answer

Two major things to consider.

First, the 905P has an 8.76PB endurance rating. The Samsung 970 Pro, one of the finest, most robust consumer SSDs on the market right now, has a total bytes written rating of just 1.2PB by contrast. And yes, that's petabytes we're talking about.

Secondly, while the sequential read and write performance appears to match other SSDs on the market, the 4k random performance is three times faster than the next fastest SSD. This highlights how well a drive will manage with the thousands of tiny reads and writes it will be tasked with on a daily basis.

Add to that built-in power loss protection and the fact that the controller doesn't need to deal with garbage collection or wear leveling, and this drive stands out even more.

Does it justify the price? Ultimately, that depends on your application. By purchasing this drive, you're becoming an early adopter of a new and proprietary technology and paying for the research, design, and development that's behind it in addition to the performance of the drive itself.

Question 5

what are its write speeds?

Accepted Answer

I am  on vacation, so I don't have the passmark specs in front of me.

all I can say is it scored in the top 99% for read/write speeds.

you need a high end board  like the dual cpu workstation board from Asrock  and 1q28 gig of ram to even take advantage of its speed.

I know of nothing even close, and I did a lot of research.

I will be back around July 16 if you can wait.

Question 6

for the read speed it says this.   < 10 us    how fast is this speed in MBS?

Question 7

Can you turn off the LEDs?

Accepted Answer

no
