SSD Write Endurance 25nm Vs 34nm

[vpr5703]

I love that the Samsung 830 has maintained such a high speed over such an extended write time. That little Kingston just won't give up either. Great thread.

Go little guy, go!

Thanks! That drive needs all the encouragement it can get.

[Kain665]

So...

Based on the MWI progression versus the TiB written for the X25E, it'll hit 12PiB before MWI reaches 1... Granted, there may be other factors but I still find that ridiculous!

[DragoonXX]

it IS SLC NAND... so it's not really that ridiculous

[Christopher]

And it's got 80GB of 50nm SLC at that. In reality, you should get closer to 300K PE cycles out of it.

300K PE cycles would be ~8.65 years of endurance... in which alot of things could happen. The end of the world could come, or some meteorite could strike it... or Mrs. Bat with a hammer

More like 14.6 PiB (1% every 150TiB)

300K PE cycles would be ~8.65 years of endurance... in which alot of things could happen. The end of the world could come, or some meteorite could strike it... or Mrs. Bat with a hammer

At the current speed it does 2,6 PiB/year. I think something else will break before the nand and to be sure I'll be wearing a helmet and the endurance rig will stay hidden

Most drives are up to date, canthearu's drive is based on the report from the 16th.

Drive has finally reached it's official worn point. It has been a good run, and drive is running a bit faster then it did when I first started it. Hopefully I can at least double the amount of written data. Unlike the earlier corsair force 3 .... Wear range delta has remained very well controlled, which may improve the eventual life of the drive.

Looking through the SMARTLOG data, the drive hit MWI 10 at:
446,307 GiB Host Writes (F1)
333,083 GiB NAND writes (E9)

Thanks for the update!

Looks like the non-Intel SF drives are a bit different on MWI, I've still got 27% (or 37% depending on how Intel handles the last 10%) left on my drive and NAND writes are up to ~380TiB.

Your intel 330 will go all the way down to 1%, just like my Intel 520 did.

Intel ported their method of measuring MWI to their sandforce drives, so the MWI goes all the way to 1%. Will be interesting if the 330 makes it all the way to 1% though .... did intel forget to set the NAND cycle feature to 3k rather then 5k on their 330 drives ... or does the 330 really have 5k NAND in it.

[canthearu]

Also, if people are looking for a drive with Plextor M3 like performance, but don't have plextor stocking their part of the world ... keep an eye on the liteon drives.

I got the following from a $90 AU Lite-On - LZT-128M3S (128gig).



The scary thing is that inside the outer casing of this LZT-128M3S, there is a mSATA converter and a Lite-on M3M mSATA drive.

Such performance is completely nuts from a normal desktop drive, let alone a mSATA drive!

[Anvil]

I could have checked how it was handled on your 520. (a bit lazy as it's holidays sort-of)

Here's a look at Reallocations vs MWI on the 330

+1...That mSata would be more than welcome in my notebook.

Where the hell do I find such an oddball drive as that Lite On? That has my name written all over it.

Just keep an eye out for bargains. Then don't hesitate because they sell out quickly.

The Lite-on drives are very similar to the corsair performance pro and plextor m3 drives. 24nm Toshiba NAND on a Marvell controller. SMART parameters are very similar (if not the same) as your M3P that was tested. However, it seems that my drive is no good at counting power on hours. Been powered for 26 hours and only showing 1 power on hour. Could be due to some power saving mode.

I don't know that you can find them here the good 'ol US of A.

@Christopher
I just tried to update fw on my Mtron but I just get this error message, both in IDE and AHCI. Got any ideas?


I used the 0.20R1 ver posted here this spring.
