(72 TB for the 240 GB version)

However, because it is a direct derivative of the SSD DC S3500, its performance in certain client workloads can be poor

The Intel SSD 730 is optimized for and performs best in an Intel RST motherboard RAID 0 setup

It's basically an SSD DC S3500 with cherry-picked overclocked controller, slightly overclocked NAND, and firmware modified for client workloads

As you'd expect from the enterprise heritage, it has outstanding steady-state performance, so you get very consistent and reliable performance, but can be slower than competing drives under certain client workloads

This is all information gleaned from reviews by AnandTech and others

Oddly enough, Intel says the NAND in the SSD 730 is not MLC-HET even though it is pulled from the same production batches

I suppose this is a separate binning of the NAND with somewhat lower endurance than the stuff that goes in the SSD DC S3500, although higher than ordinary consumer/commercial-grade NAND

Question: lot of .exe folders are created on my windows7 Answer: try that... The question was closed at 11:57:57 (according to the hover-over-"x-mins-ago" bar) and the answer was posted at 12:16:35. It's a fairly lengthy answer, so it's possible that it was started to be written before it was c...

You technically have four hours to submit your answer after the question is closed, as long as you loaded the question page before closure

Don't reload the page and you should be fine

Ramhound

That is good to know :-)

Now where did I see that damn block diagram of this device :$

Do note that there is a client-side restriction against submitting the answer, but you should be able to bypass it by manipulating the submit button in the developer tools

This is going to be a very specific answer. Since the type of NAND technology in a SSHD will be completely different going into tomorrow and the future. So the current STX000DX001 Seagate SSDH product line uses Commercial Multilevel Cell NAND. Here are some benchmarks Storage Review ran on a p...

Oh you mean the brwoser developer tools

I thught you mean SE Dev Tools

I really want to extract this block digram from this eariticle

I have no idea how to do that though :-(

Its a flash document....

If that does not answer the users question; It can't be answered :-)

DragonLord

Actually, remove disabled=disabled

Ramhound

caught one error, accidently said it WOULD be stored there :$

If he really wants to know. He can read that eArticle :$

Although I am pretty sure of my conclusion :$

HAHA karama is great. That Lizard Squad DDOS service did't store passwords correctly!

@Ramhound For NAND, commercial-grade and consumer-grade actually mean the same thing.

The answer seems fundamentally incorrect as a result.

Ramhound

Alright; I can adjust that portion

Still doesn't change the fact; The hibernation file isn't ging to be stored in it

considering the size of the file will entirely be based on the system state

DragonLord

You did see the image, right?

Ramhound

Yes

This SE team will likely remove the whole grace period if it is abused, so only use it if you really have a good answer

I, for one thing, have never had to do this

Ramhound

I won't remember how 5 minutes from now ;-)

I have about 1MB of long-term storage.

A block cache would never ever be useful in the situation of a hibernation file?? it was just freshly written, newly everytime it is written out? it is only read one time? a hybrid would be stupido to put that pig in its faster cache chunk?

Ramhound

95% is devoted to the memory of my dog.

That a quesiton or a statement?

Psycogeek

A question of the logic of the hybrid and the hibernation .

Ramhound

I was discusted with the flash article so only read the highlihts ;$

But it appears the thing is used as a giant 8GB cache.

But I am pretty sure the entire hibernation file would end up on the mechanical drive.

Just managed to switch to RAID mode without a BSOD.

To enable the RAID driver, in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorA, set Start to 0x3 to disable the Intel RST AHCI driver; in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAV, delete the StartOverride key to enable the Intel RST Matrix RAID driver.

Then reboot to UEFI setup and switch to RAID mode.

If i remember right both hybrid drives and hybriding 2 drives (ssd+hd) with the driver/sofware , the writes always go to the platter, even if it is also in the flash. the key speed-up that happens is when data that is read over and over is stored in the flash. The whole thing has very little speedup overall even intel showing it at 25% real use situation. not even worth complicating it like that. So if a person wanted real speed they would use a SSD, and get 3-4 times real speed .

After looking at the stats and specs (more than a year ago) it was a bad idea to think it could be applied to "larger" disks to get speed for the parts that you use a lot. It was way more practical to me then, to put the stuff needing speed ON the speeder, and putting storage stuff on the slow.

" why not just get a big SSD instead of messing around with hybrid technology?" – Tetsujin . . . Except in situations where you could figure that would be your use pattern? like wouldnt that work well for a server that feeds the same crap to 3000+ people, and has other stuff lying around that nobody looks at. WHere most of what occurs is reading of what has been put there once.

DragonLord

Note: Trim should continue to function as this is Intel RST version 12.9 (with version 12.6 in firmware) on an Intel 8 Series (HM87) chipset.

Switching back to AHCI mode for compatibility—there's no real advantage in RAID mode because I don't plan to do RAID

Create a key called StartOverride in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAV, then add a DWORD value called 0 (numeral zero) with the value 0x3

Then set Start in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorA to 0x0

Psycogeek

1:49 AM

Isnt it odd that the AHCI/IDE thing completly crashes up the machine when many many other driver issues of this type would instead be "compatable" and just not be as good in the other modes, or without the tricks.

DragonLord

What happens if you do this wrong?

DragonLord

Pretty stupid that you have to manually set the driver to use in the registry to make this change

Psycogeek

This only gets me, or bugs me most when solutions for some hardware issues are to "reset the bios/uefi" and most motherboard will also reset that. so without one more freaking warning given when telling people to reset the bios, they now have 2 problems :-)

ugh

I was about to ask a question on SU, reviewed the steps I took, missed something obvious....

and now I'm not sure if its cause I opened up the port (which I swear I did before) or me futzing with selinux permissions

Psycogeek

@DragonLord cooler than a nuclear battery, but it looks rather small for a fuel cell to be fast charging capable of . . . 2watts continuous output , sounds about right, now do the math for how many miliampers that would be at 5Volts

DragonLord

@Psycogeek 400 mA, pretty slow, but it's power when it matters most, entirely independent of the grid

Psycogeek

A 1 Foot square solar pannel could do 2 amps. that is one of the thing i use off-grid

DragonLord

2:44 AM

@Psycogeek That's much more cumbersome

Psycogeek

about the same weight, much larger size and most devices are not efficient when using it that way, so i had to wire it all up myself in a more direct way.

DragonLord

I have limited off-grid equipment beyond a small jury-rigged (1.5W) solar panel, but even that can make a difference

Psycogeek

400ma of solar could "fit" in the same space as that thing, folding out , most of them having also a li-ion battery as the buffer for charging.

DragonLord

That panel is not well-behaved with every device, but it'll do for me

At least I have a USB-powered 18650 battery charger (used for my flashlight) that is designed to tolerate unreliable or weak solar input

I've tested it and it works well with the panel

...and at least one of my power banks will charge from the panel

Psycogeek

Which just leaves how they solution the "cleaning" of the fuel cells when used with hydrocarbon gas ? If i remember right that was one of the fuel cell problems when not using raw hydrogen.

"A totally new energy supply technology . . . "
Fuel cells were developed in the 1960s as part of the USA NASA's space exploration

Platinum catalyst , the automobiles use that too to burn off excessive hydrocarbon fuel that did not get burned up in combustion, and those catalytic converters last a good long time and a lot of not so clean fuel passing on through them.
