SSD Write Endurance 25nm Vs 34nm

[Christopher]

@ Anvil -- that was just a typo.

[Christopher]

A new Chart


Temp, Avg MB/s, Hourly GiB written, Wear Leveling Count, and MWI are all included. I'm using a logarithmic scale. Again, open it in a new tab for your viewing pleasure.

Speed and temperature are pretty much in lock-step.

i cant get it to open in another tab.

If anyone cares, I'd be happy to present the info in some other way.

OCZ Vertex Turbo 64 Day 38

84.33 MB/s Avg
912 hours

4817 Avg PE count
4 MWI

0/0/0 Read/Program/Erase Fail

------------------------------------------------------
The 830 is now at MWI 50 and over 407,000GiB!

The Vertex Turbo is almost to MWI 1, but really when MWI = 1 it should really be MWI = 50.

The Cognac FW 1.6 or later puts all MLC PE counts at 5000, even when they should really be 10,000.

[Christopher]

The Vertex Turbo has made it to 4900 average PE count, or MWI = 2. Min and max are 4068 and 5262 respectively.

No reallocations just yet, but surely some are bound to be around the corner.


The Super Sexy Samsung is at 426,502 GiB and 427 hours.

EDIT
the VT should hit MWI 0 in about 18 hours from now, but I don't know if it should really be MWI - 0 or MWI - 50.

SSDLife Pro stopped working again so you just got CDI this time. The most interesting thing going on is that the Intel got reduced Reserve space as the reallocted sector count is increasing.

Just some general comments:

The torqx 2 seems to be hanging in there. It still can't count hours, but it hasn't suffered cataclysmic problems, nor has speed dropped any. Just wish it was a bit faster because at this rate, I'll still be posting updates on it in a year's time. MD5 checks indicate that it isn't even losing data

The Intel continues to be boring as hell in its military precision and slow match to its own demise .... how far it goes is anyone's guess ... the NAND isn't showing any signs of disfunction. The intel 520 will probably go like many of the other drives ... by forgetting its contents one day during after a retention test.

[Christopher]

My SSDlife stopped working too. When the VT hit MWI 0, it stopped updating. I restarted it, and now I get an improper argument error. Deleting the data file would probably solve the issue for me. I just need the program because its easier to take screenshots remotely on a touchscreen device with the screen capture button.

[B.A.T]

I got the same problem. The program is just blank but I'm able to take screenshots with teamviewer so I'll use CDI until I'm home next week.

[Christopher]

I'll delete the info file for SSDlife and report back.

The VT is still without a reallocation after 5100 PE cycles (almost). however, bit errors seem to have increased.


see attributes CA and CB.

[B.A.T]

Same as I got on the first m4 the last 100 TiB of writing but it had over 12000 P/E.
It'll be exciting to see if it increases steadily or accelerate as you burn P/E.

[Christopher]

I really like the Turbo's performance so far. It's looking like a completely different drive than the first one I put up, likely due to the first drive having some questionable quality flash.

I restartet ASU on the m4 on accident but everything runs fine.

[Christopher]

The most interesting aspect of the Vertex4 is it's 128bit ECC. I wonder how it would fare in the endurance test.

Do they come in 60 GB flavors?

Nope. 128, 256, and 512.

I'm expecting Available Reserved Space [E8] to start decreasing. (as is the case on B.A.T's X25-M, no signs of that yet)

The drive will be offline until tonight, so it will be sort of a retention test. (it's just ~12 hours)

[Ao1]

Do they come in 60 GB flavors?

I wouldn't bother gettting the Petrol version. It is using Hynix H27UCG8T2MYR-BC and it appears to have a problem retaining data.

Post 7 onwards.

(and there are plenty of other threads about bad blocks and data corruption, so I don’t think this is an isolated case).

Notes:

I have confirmation from Patriot on how to decode the smart values from the Torqx 2 - http://www.patriotmemory.com/forums/...0808#post50808

Looks like the Torqx 2 has fairly high WA in this torture test, which would explain it's low speeds.

Did you record GiB written when WMI changed to 0?
