SSD Write Endurance 25nm Vs 34nm

[Kain665]

B.A.T., Any idea why the X25-E has dropped 10mb/s in speed?

[B.A.T]

BAT, I'll do some power consumption testing of my 32GB MTRON today, It uses 50nm Hynix SLC and not the Micron stuff, but power use should be similar. I've never seen any power usage stats for MTRONs, but I bet they don't use much.

I'm just kinda curious. Right now, the 830 is using over 5w and the M3P only 2.5w.

That would be interesting. I don't have any equipment to measure so I can't help you with that.
Btw, my Mtron got Samsung SLC nand but I don't know if it performs different than Micron/Hynix.

B.A.T., Any idea why the X25-E has dropped 10mb/s in speed?

I think the E has settled in. The write speed has been very stable the last 10 days.

Both drives are now entering a data-retention test, will reconnect Sunday night. (~48 hours)

[B.A.T]

Retention update:
The test is over and both drives are live and kicking

They work fine and are back at writing like before. Not much changes in smart but there was 2. I'll put them in the status for each drive in bold.

Not sure if you guys are interested but CDI 5.0 is just now out of beta and available for dl...

I noticed the 5.0 release, tried it last night. (been using the beta for a week or so)

CDI5 now supports SMART attributes within RAID array,
i've tried with Intel ICH9R with R5 and Z68 with R0)

I've been negligent in my updattes the past few days. I nearly killed another MTRON trying to do power consumption testing, but I was able to save this one.

[Anvil]

Both drives survived the retention test, they were disconnected for 48 hours 20 minutes.

No changes to SMART.

[Christopher]

Right now, the M3P is chewing through PE cycles. At 500,000GiB, and assuming WA=1, the M3P is at 3900 PE cycles. But since that's not possible, it's probably around 4300 PE cycles if WA = 1.10.

We have another kingston here :P

But seriously, these Mtron drives are proving to be seriously unreliable/fragile. Just highlights the importance of firmware quality.

SLC + bad firmware = still a bad drive

[kensiko]

Hey I had to say that: Did you look at 480GB prices? It dropped like crazy, this is a really great price for this one: http://www.newegg.com/Product/Produc...82E16820226255

[Christopher]

I'm a fan of the Deluxe, but I could live with a 480GB for that price.

You know, I've had a hell of a time with the MTRONs on SATA III ports. It shouldn't matter, and yet it does. A couple systems of mine won't boot with an MTrON on 6gbps Intel PCH.

[canthearu]

Battleship MTRON would not last long in your hands Christopher :P

Hey now, I've only killed 2 of 5. I was able to save the third, and the fourth is powering the endurance rig. The fifth is somewhere around here, and if it knows what's good for it, it will stay out of my sight. They're all lucky to be alive, TBH. They're complex, but this is out of necessity. They're IDE drives with a SATA to IDE bridge attached with gaffer tape for good measure. Any one of a number of components could die, and any number of firmware maladies could claim them. They're the proto-SSD on the evolutionary tree of solid state storage. That they're as awesome as they are is a miracle. That they don't die more frequently is also a miracle.

Haha, I do agree, especially when you put it like that

rofl...you sound a lot like me when I get fed up with something. If you go off the deep end, you gotta post a vid of you wielding a 15lb sledge hammer.

Sledgehammer? I can kill an MTRON with my bare hands. They're delicate lotus blossoms, and I'm losing my patience with anything not carved out of solid granite. In all seriousness, I don't think they play well with some modern hardware. And that's sorta to be expected, I mean, my X25-Es will keep windows from booting if they're on an Intel 6gbps port. My Chronos Deluxes will prevent this one AMD board I have from booting proper if it's on any of the SATA 3gbps ports (it's a 7xx southbridge, no SATA III). I still like the MTRONs, but damn if I'm not just plain scared to use them at all. I'm going to cowboy up and do the requisite power consumption testing though.
