I've had this Intel 320 series 120gb sfor about 5 months... here's my capture, it's the sole drive in my build, I use a 1.5TB external for all storage needs..most the time I keep about 30-40gb free on the SSD.

Also, side question, I leave my desktop on 24/7 for the most part, this shouldn't be an issue with an SSD, right?

Leaving computer on 24/7 shouldn't cause an issue, especially for an intel drive. Only issue I've even heard of was when virtuallarry ran F&H 24/7 using his ssd as the F&H main directory and data drive, but he was on a pair of 30gb ocz's, and the issue was quickly fixed by moving his main F&H directory to his data drive. I think that he had several TB of writes after 5-6 months.

edit: as a comparison, SETI caused me zero problems when I ran it on my x25m g2 for 2 yrs 24/7. However, when I read about virtuallarry's issue, I did move my installation over to my 2 tb storage drive.

Some of my SSD write statistics:

Intel G1 80GB - 10TB (3 Years of use)
2 x Intel G2 160GB - about 8TB each (Both around 2 years old)

All my other SSDs are too new with ~1TB or less writes.

From CrystalDiskInfo:

F1 Lifetime Writes from Host 1216
F2 Lifetime Reads from Host 1359

I guess that's in GBs?

Installed Win7 to Vertex 3 in 8/2011
Have mechanical HDD for media/storage.

64GB Vertex 2, on 24x7 as OS drive in a light use server: xen/media server/mail+web server/xp for bittorrent all the torrents and media are written to HDD

9 Power_On_Hours_and_Msec 15141h+07m+01.530s
241 Lifetime_Writes_GiB 3776
242 Lifetime_Reads_GiB 6912


Everything else is too new to be interesting... however the mirror to the above disk that was just installed a couple days ago claims it's got 0GB of writes. Need to keep an eye on that one.

My Intel SSD 520 has about 465GB written over it over the past 2 months. Granted the only games I play (now - until I upgrade my video card) is Dota 1 and Dota 2. I also moved the Internet cache files over to my hard disk since there won't be any benefit placing these on the SSD anyway (and I figured they write an additional 1-2GB a day depending on how intensive my browsing is).

Actually, I haven't bothered to move the BOINC (not F@H) stuff to the HD. Maybe if/when I reformat. Currently sitting at 8.7TB of writes after 5 months 8 days of power-on time.

I wish I knew how to find my SSD's write statistics..
Niether CrystalDiskInfo nor the Intel SSD Toolbox is showing me any SMART data past item CE ("Flying Height" according to Intel, and "Write Error Rate" according to CDI.)

Do you have a HDD installed, as well as the SSD?
If so, you might have to go under the "Disk" menu and select the SSD as the one you're wanting info for.

I have 4 HDD's in my system alongside my SSD.

I have made sure that the SSD is the drive selected for data display in both programs, but they simply will not show me anything past attribute CE.

I'm at 1.07TB of writes and it says health is at 100%, so I guess that's good.

How many writes would put it in danger of not being able to write to the NAND cells anymore? If it's more than 100TB then it doesn't matter much, but since it says drive health is 100% I suppose it's more than that.

LOL_Wut_Axel,
If you look here http://www.xtremesystems.org/forums/showthread.php?271063-SSD-Write-Endurance-25nm-Vs-34nm (Scroll down to the last two graphs of first post) The Corsair Force 3 made it to 438TB before WMI was at 0% at 46% compression ratio. (At 0% WMI the drive is supposed to retain data for 1 year powered down) It died at over 1000TB, so you got nothing to worry about for a very long time. (Vertex 3 is same controller but faster sync NAND)

DarkRogue,
I'm assuming you're talking about your M4 in sig. I don't know which SMART attribute keeps track of writes but attribute AD keeps track of wear leveling count. You can use that to estimate the writes. NAND in the M4 is rated to 3000 cycles. Also attribute CA shows the percentage used of rated life.

Lifetime writes: 2485 GB
on my ext4 partitioned M4 128GB

appears none of us are anywhere close to wearing anything out ...

Yes, it's the M4 in my sig.

Attribute AD does indeed state a count of wear leveling, which currently has a value of 35. I guess 35 / 3000? Or 5000, I don't know which NAND this one has.

CA has a value of 1 ... whatever that means, lol.

Just sucks, as I was curious exactly how much data was being written to my drive, and it seems everyone else is finding these numbers without issue. :(

Besides disabling defrag and other stuff, I really haven't given a second thought to "extending" the life of my SSD by turning off various things and moving other programs off it. I have a page file, temp files, caches, and everything else on here, as well as Photoshop routinely thrashing it for scratch space. It seems even with this 'abuse' it won't die for a long time, but I'm still curious about the writes. :p

Its 35/3000 which is around 1.17% of drive life used. Which is why CA has a value of 1. So just going by that 35 x 256GB = 8960. So you probably written somewhere ~9TB worth of data to the drive. How long have you had the drive for?

Intel rates their NAND at 5000 cycles so it could be likely that Crucial is just being conservative with their rating. (Micron NAND is used in the M4)

Wait; how do you use CrystalDisk Info to figure out how much data has been written? All I see with my C300 is 93 Wear Leveling Count. That doesn't tell me anything?

I have had this drive since the end of October, so a little over 5 months now. PC is on 24/7, except a couple times when I go on vacation for a weekend here and there.

I know Intel rated their NAND at 5k p/e cycles, but I was under the impression that since Micron was part of IMFT, that they'd get the same 5k cycle NAND.

3.2 TB on my G2 120 since early Dec 2011.

4 re-allocated sectors.

Not sure about my Crucial M4 since I forgot what program to use to check it.

189 Factory_Bad_Block_Ct 88

I had 88 for that smart value when I got my M4
what kinda factory counts do you all have ?
