MX500 rapid erase cycles, seems to be poor wear levelling

[mb194dc]

The 23 version firmware definitely reduces the erase issue and extends the life of the drives, at least for the way I am using them in a Server. It may not totally fix the problem. If I had one of them in a home system, be interested to see how long would last past what the SMART data is saying as an experiment. Not going to do that in a Server though!

Meanwhile I had my problem drive changed out and ended up with one that has the same problem and the older firmware on it. Will get another one put in later...

Funny Cutechri drives are older than mine but she got the newer model.

If you're talking about the firmware - I updated it myself, as I've already stated.

The older models cannot be updated to the newer firmware?

Hi,
Temperature is terrible at 45c

These drives are rated up to 70 degrees, so no, no it's not.

no, the 33 and 43 versions are for the mx500's with the newer controller.

Hi,

Confused; that is just over body temperature and a lot of PC cases can be 45°C internally.

Hi,
Idling doing nothing at 45c is way to high
But then again could be a sammy m.2 so normal

So these come with M3CR045 now, there is no firmware upgrade from M3CR043 or M3CR044, reportedly M3CR045 has a flaw that results in hangs.

I have a MX-500 (1 Tb) CT1000MX500SSD1.

TBW shown by the official documentation is 360 TB (see ref). Mine has only 18 % life remaining while I only wrote 108,501 TB.

I know I use it a lot, but still. Only 18 % life remaining while I don't even used half of its cycles, I really think this is bad.
Some ideas ?

I had a Crucial M4 256 that died for no reason, had like 98% life left.

Computer blue screamed and drive was dead.

No more Crucial for this guy

I'm about to say the same thing. This is sad. I really liked Crucial in the early days. Like I was a big fan of WD till the moment they sold their crappy WD green thingies.

Looks like I'll have to find another brand for SATA SSDs...

BTW, nice computer that you have I'm about to order a 7900X. Can't wait to have it ^^

Did you not read a single post in this thread?

Hi,
I still have couple very old mx100's 256gb being used at about 10 years now atm with 1-win-10 and 1-11 on my z490 rig
One died but it was a incompatible firmware with linux clash that killed it "linux never ran trim" not anything else.
RMA'ed and it's still working today same as others of which a couple mx100 128gb in an old lappy.
Yeah a lot smaller ssd's but seem like an energizer bunny line

 

[swaaye]

I have a few MX500 250GB drives at work. They were $25 one deal day. They may have slow writes that cause the occasional system hitch but for $25 I think they are uh quite awesome really compared to the hard drives that were in those PCs.

I had a Crucial M4 256 that died for no reason, had like 98% life left.

I have a M4 128GB still chugging along. Every now and then it needs two power ups to get a bootin. I figure it is 11 years old at this point and yeah has a lot of hours on it so no complaints really. For all I know the problem is actually the funky OEM Acer B85 motherboard.

I am still waiting to have a SSD in a desktop role fail from flash wear. There is a Samsung 830 at work in an ancient Core 2 system that's at like 60% lifetime. That thing has been on 7 days a week since new. I know of an OCZ Vertex 2 60GB still out there at a coworker's house. I thought it bit the dust at one point like 6 years ago but I secure erased it and reinstalled Windows and it's been good since heh. A few SATA 3 Sandforce drives out there too yet.

its the SSD, known issue with M4's.

I opened support case with them, let's wait for reply.

 

[Sora]

internal as well as host to device writes are counted towards the decay of the disk life counter, in the case of the M3CR02x devices the internal writes are several factors higher than host writes, this is corrected in the M3CR03x and 4x based MX500's though its unknown if this is a result of the new nand controller in use in these or the firmware itself.

 

[mb194dc]

Those M3CR023 drives are going to wear down fast per reasons above.

It's reasonable to assume it's the controller because if it wasn't then Crucial would simply have fixed the firmware ages ago... Hoping when I need to swap my drives out again get ones with the new controller!

The new variants come in a slightly smaller rectangle box, the old variants in a square box.
You can confirm with the retailer which one they are shipping and act accordingly.
