My 64GB Falcon II doesn't report a GB write number, so I have no idea. I've had it for a bit over two years and it's at 9150 power-on hours. It's on its way out though:

13% health and it's dropping at the rate of a point every 2-3 weeks.

From your C7 - Total count of write sectors, it looks like you only written about 4.6TiB, which would be nowhere near to wearing it out. Also you don't have any reallocated sectors, attribute C4.

I think there was some issue with certain fw versions showing incorrect health for indilinx drives but i'm not 100% sure. There is a newer FW version available for that drive as well.

Can you post a full SMART list?
 
M4 512GB since November 2011:
AD =10
CA=1

I have used about 0.3% of the drives writes for a total of ~5.1 GB.

I still have an old Intel G1 80GB and its only used 6% of its writes despite its long working life.
I have had a Vertex 2E fail, but another one is still serving me well and I got an agility 3 as a replacement which is pretty neat.

In all in the last 4 years I have lost 1 out of 4 SSDs.
In the same period I have lost 11 out of 11 hard drives, but bare in mind some of those are multiple replacements on the same drive, not all drives have actually failed.

Thanks for the tip on the firmware. I updated it to whatever the latest was back when I bought it but didn't realise there is a newer one. I'm a bit reluctant to flash it just in case something bad happens, and I'm looking at getting a new system with a new SSD in a month or so's time. I'll wait until I've set myself up on that till I update the firmware.

Yea good point on the firmware flashing, especially for Indilinx drives.

From those SMART values:
CE - Minimum Erase Count - 1B82 hex - 7042
CF - Maximum Erase Count - 28C9 hex - 10441 (that's above the spec of the NAND)
D0 - Average Erase Count - 225E hex - 8798

C7 - Total Count of Write Sectors - 24A8E7027 (each sector is 512bytes)
That gives you 4692 GiB written.

That's some huge write amplification if those figures are correct. In the link I posted earlier in this thread similar Indilinx drives made it past 200TiB before erase count reached NAND spec.

I guess it may be possible if the drive was mostly full and in a non Trim environment, still those SMART values just don't seem right. (Unless I made a logical error somewhere 😕)
 
Hmm Im using the Intel SSD tool on my m4, and Im not finding this info. Here is a screenshot. Maybe I just havent used it long enough for it to start registering?

Hey guys did you know with SF based drives that you can determine both HOST writes and NAND writes? This gives some interesting data as you can see the difference between host writes and the combined resulting sum of compressibility and WA.
For OCZ SF drives:
Attribute #233 (E9) records the write to NAND.
Attribute #242 (F1) records host writes.
For the Intel 520:
Attribute F1 records host writes
Attribute F9 records NAND writes.

 
In intels RST software you need to change your acceleration method from enhanced to maximized. Note that you could corrupt your Windows install using this if you have a power loss or other issue.

Not sure what you mean here. You have to use IRST to enable SRT. Are you thinking of TRIM + RAID 0 still not being compatible, perhaps?

I thought that I checked the advanced tabs the other day and it just wouldn't let me click "enable", but I'll check again when I get home.

You think that's bad? My max erase count is 27420. 😛

I checked my brother's 120GB Falcon SSD (Firmware is 1517 I think). 7.5TiB writes, 86% Health remaining. The max erase count is ~2400 and average is ~1800. (Which is still a high WA) I'm not sure whats going on with your and MrMaestro's drives.

You've only got a wear leveling count of 1, so only 64 - 128GB has been written to the drive. Its still brand new.

Thanks, thats about what I was thinking (too new)
 
Hi,

Can someone help me interpret this? I am trying to optimize what I install on the small SSD since it is about half full (16Gb/30Gb used) with Win7 and updates.

I want to know if I should worry about moving things like temp files and firefox/chrome caches onto my storage HDD.

I believe it is a first Generation OCZ Vertex drive.

Thank you.

Not sure how accurate it is but using SSDLife Pro, I get est. life of 9 years.

So far, with little use it is showing 0.6GB written/0.2GB read just today with 42GB/54GB total write/read. Sure that has been reset after I did a secure erase? I have been using this drive for about 2 years and it only shows powered on 24 times and worktime of 3 days.
 
My Plextor 256GB is at 6.07TB NAND writes after being on 4741 hours. The Vertex 3 is at 600GB writes after 1414 horus.
 
The power-on cycle counter reset a few days ago when I updated FW. Should be a hundred or so. I've had it since last May.

A computer running an SSD 24/7 isn't an issue. The Corsair Force drive I have has over two years of constant-on time. I'll post usage later.
 
It is dificult to say how much writes there are because i have a devided load from ssd raid 0 with seperate boot ssd .The boot ssd where not the same al the time tryed the 320 and 80 Gb postvlille and raid boot , but the G2-V is ms slower than his big 80GB brother for windows .And i have made XP that it almost does not hostwrite, the Boot ssd has 964 GB hostwrites for 3236h power on.
Think whe al seen the test made by anandtech abouth raid ssd http://www.anandtech.com/show/3618/intel-x25v-in-raid0-faster-than-x25m-g2-for-250

That test made me buy more than one ssd to set them in raid , like it a lot because i already had raid hd drives with the same 80GB size . The same drives only much faster seqentieel loads :biggrin:

The media wearout indicator is going down correctly from 100 to 99 for the oldest pair . And alot unsafe shutdowns
