SSD Write Endurance 25nm Vs 34nm

[bulanula]

Too bad the Intel X25-V is such a slow writer. We might have to wait a long time till it dies

I think this was the goal Intel set out from beginning. I am pretty sure they can write faster but don't, for exactly this reason.

[Anvil]

It's not an issue at all imho, it's a low capacity SSD, one does not do much sequential writes at all and for random writes they do very well.

I've got 3x (1x Kingston and 2x Intel) running as boot drives, the one thing I do notice is that 40GB is on the small side and so I might have to replace one or two of them with a 60-64GB drive.

[Christopher]

I moved the Mushkin last night to a SATA II notebook. I didn't have a Win7 image for it, so I had to install Win7 from a flash drive.

It took two attemps. The drive disconnected/became unresponsive half way through file expansion the first time. I gave it the benefit of the doubt and just assumed that it could have been something else (but not likely).

It's been running nonstop since, but at a greatly reduced speed -- 26MBs+ less average.


Anvil, I have seen the wear range delta go down with the Mushkin, but infrequently.



You'd have to pry my X25-V's out of my cold, dead hands. I love those things. They are perfectly capable of giving you the random performance and read performance to make a great boot drive, and are nifty when RAIDed. I tried to buy two more at an auction, but got out bid. I think they're a better boot drive than any Indilinx was at the time.

@Christopher
I've checked where/when it stops in the loop and it is not any particular part, it does look to occur mostly during deleting files or within a few 1000 files after a new loop is started.
I've seen it happen at the end of the loop as well so it is not related to any fixed part, it's just looks to be more likely to happen when the drive is stressed.

If/when it disconnects again have a look in the TEST folder, there will be remains of the previous session.
(you'll know where it was by looking at the number of files and the file names)

[Christopher]

Anvil,

Also you can tell just by the available free space.

The first three crashes did occur at the end of the loop during deleting, but after that the crashes were different as I've explained before. I've moved the Mushkin from the laptop back to the main rig, so we'll see...

Also, I initially tried using the Mushkin on one of the SATA II ports on my P67 motherboard and speeds were only a few MBs less. On a Core 2 Duo's SATA II ports, you lose >20%.

I have a good feeling about the drive's prospects from now on.

one thing that would be a tiny bit helpful (if someone has the inclination to do so) would be a list of who is running which SSD, as i am getting lost on a few of them.

With the multiple entries, it could be useful. For instance, before Vapor's chart update, I didn't realize how many drives were actually running.

Those are the currently running drives, and owners, that I can think of off the top of my head.

SymbiosVyse doesn't ever put the name of the drive or an SSDLife/CDinfo shot, so I can never remember what he's running.
The Samsung's not running anymore, on account of being dead and all.


CT, Does that help?

Vapor, could you please label the charts some where with this info?

I had another disconnect. Since it's a secondary drive there was no hang and I was just able to unplug the drive's power and plug it back in.

Is it possible turning off hot-swapping for Intel RST would be able to alleviate some of my problems?

I've heard it mentioned as a "fix" but not in a way that gives me confidence -- and at least now I can fix it without a reboot.

You missed johnw with the Samsung 470.

There is also some LPM stuff...dont know as i dont have any SF. but there is a long detailed process you might try over at OCZ.

I'll add it.

I did look at the OCZ forums... I kinda ranted about it the other day.

I've seen it mentioned in the Mushkin and OCZ forum -- I think there's a BIOS setting for it, so next time I restart the machine I'll try disabling it.

EDIT
My Intel DP67BG doesn't have bios options. Disabling hot plug stops the drives from being treated as external drives according to OCZ. Furthermore, they claim Intel's chipset 'madness' is to blame, saying that not all P67 chipset 6gbps are the same, and that they don't manage power properly.

Sounds fishy as hell, but maybe there is something to it. What kind of power management do the drivers try to do besides turn the drive on or off? It does kinda act like an external drive at times. I'll see if I can disable hot plug through regedit.

Looks like the Intel BIOS just enables it by default -- which is good because OCZ says to enable hotplug. All my LPM stuff is fixed anyway in the registry... so that doesn't really leave much. It crashes more with the msahci drivers so that doesn't leave much that I can do besides try a different motherboard, or get a Marvel controlled PCIe adapter to put the drive in.

This time it lasted for ~33 hours.
It disconnected again last night 07:01 CET, so about 6 hours ago and again while deleting files, this time all files were deleted.

I'll move it to another rig this weekend just to see what happens. (another Z68)

I've lost about 18 hours in the past week to disconnects... It disconnected again again last night about an hour after I went to bed. The worst time that it can happen.

This weekend I'm going to swap out motherboards for an H67 and just hope that helps.

[Anvil]

I might try one of the other (non SB/PCH) ports on the current rig, not sure what it is but it's one of the typical add-on controllers.
If that doesn't work out I'll try the lsi 9211, if SMART still works that is.

It's annoying alright but I'm not giving up on the drive.

No, I won't be giving up either, but that doesn't mean I'm at all pleased with some of the nonsensical explanations and voodoo magic solutions. I think this is how many of the Vertex 3 owners felt after the products' launch, and part of me just wonders if the some of the SF 2281 controllers are just faulty. If worse comes to worse, I'll swap it out under warranty and try with another... But that's the worst case scenario.

Until I switch to another motherboard, I've switched to a SATA II port, so we'll see if it helps. I tried it last week, but just to see what kind of speeds I'd achieve.

With the P67's 6gbps port I was getting 122 - 124 MBs avg.
With the P67's 3gbps port I'm getting 117 - 119 MBs avg.
With a C2D ICH8m SATA II laptop I was getting about 94 - 96 MBs.

I can live with 118MBs if it means I can make it through the night, but I'm not sure that Sata II ports are any less prone.

[sergiu]

I would be interested to know if the issues are more hardware related or there's a combination of hardware-software (drivers with issues that occur under certain conditions). For ruling out software, you could install a Linux distribution and run any program that would generate continuous writes, as SMART parameters are already tracking everything. I know this might be a too far suggestion but it might worth trying.

While I was at work ASU reported errors and froze. I could open folders and files on the SSD but ASU had no response. I shut it down and tried to open it again. Now the startscreen came up but the program froze while trying to load information. I powered down the rig and tried a restart. Next problem now was that the JMicron optionrom couldn't find the Kingston so I disconected it and took a new restart.
I moved the Kingston til SB850 and got help for Anvil to restore the log and now all runs normal again. The MD5 check showed no errors so I don't know what caused all of this.
Here is a screenshot of ASU with the error message.

@sergiu
Not very likely, it would be the last thing I'd try, if there is something to the SF/SB platform mix that stinks I'll make sure to test on other SB computers and then go down the X58 route as well before trying another OS/platform.

I've lost a lot of time with the issues I've had. I'm running it on SATA II until it crashes again, then I'm switching motherboards to see if it helps.

EDIT
I've heard that the Marvel controlled SATA III ports have problems too, but instead of switching to another 1155 board, I think I'll get a PCIe SATA III controller. If that doesn't work, I'll buy some kind of HBA. If that doesn't work, I'm flying to Sandforce HQ to yell at someone.
