SSD Write Endurance 25nm Vs 34nm

[Christopher]

What other drive would be able to do ~300MB/s on average, except maybe for the SLC in the other thread.
(not many "consumer SSDs", if any at all)

The M3Ps and Vertex4 256/512 can probably beat it. A 128GB M3P can almost match the 830 256, it averages 280MB/s after a couple loops. It couldn't manage 300MB/s averages, but it can do 285MB/s. That's what the 830 did for the first month.

As long as the Plextor (or any other drive) don't carry the needed SMART attributes it's not a candidate for testing, imho.

I might end up waiting for something with the new Marvell controller, most likely a drive with more than 64GB capacity.

[Christopher]

It seems like Marvell-controlled drives not made by Crucial have an annoying tendency to have almost no SMART data. But if you've tried Arowana FW for Barefoot drives you'll notice it gets rid of the excellent Cognac Indilinx SMART data, and instead gives you something like Octane SMART data. So who knows? Half of the people on the face of this planet that care about SMART data happen to be us, so I'm sure there isn't much call from the public for more comprehensive SMART data in the future.

Yes, but I kinda feel like using a 256GB 830 is cheating. However, there are drives which can write much faster in ASU, but I think the 830 has the right mix of GC/TRIM to keep it from going all pear shaped in a hurry.

Well, hopefully the M4 - 64gig gets there

And I am always hoping for a good result from my 520. So far, so good!

I expect a lot of drives to get there, my Force 3 was just bad luck, the firmware wasn't ready for prime time and so it was running for months with all sorts of issues. (mainly disconnects, which quite often can be seen as a clear warning)

I'm still considering running a Force 3 120GB again.
(it's still in the box )

[canthearu]

Make sure you use the 5.0.2 firmware if you want to retest the force 3. Would be interesting ... maybe 25nm production has gotten better over the last year.

[Anvil]

The latest released fw from Corsair is 1.3.3 (late October).

Patriot released 5.02 a few days ago (April 30)

5.0.2 Release Notes
- Added Nand Support
- Updated SMART and Log Support
- Improved hardware handling
- Improved internal read buffering
- Improved block count management
- Improved Power Management

Will wait for an update from Corsair if I decide to use it for testing.

btw
The drive I've got is just as old as the one I tested (got them more or less at the same time), so in case it gets tested it won't show anything new on the NAND front.

edit:

I noticed that OCZ released a new one about a week ago. v 2.22

Looks like I've got a load of drives that needs updating.

Nothing much to report. Who wants to wager which drive will be the first to pop a block?

[Anvil]

No "bad blocks" yet on any of the drives, almost unheard of.

Really hard to tell which one is the first to start reporting and maybe that'll jinx the drives.

The Intel's (X25-V and the 320) both started reporting bad blocks pretty early, looks like the Intel's handles bad block really well.

I think this Turbo has some good flash in it. And the 64GB 830 didn't flag any blocks until almost 6,000PE cycles, and that was during the period in which it suffered from a lot of WA.

I think it would be fun to wager on these drives. It would be like gambling on horse racing for storage enthusiasts. We just need some data to establish odds on the drives...

[Anvil]

I tested the new SF fw on a few of my V3s and boy have things changed.

I need to re-check my benchmarks/tests from last night but it looks like they have made a lot of changes, performance has changed a lot.
If what I see is correct I will be testing something SF based with the new fw for sure.

The new 5.02FW is a whole bag full of interesting! They're doing something different for sure.

The price of the M4 is far and away the most aggressively priced drive on the market. Few companies are going to be able to match it. But you have to think the drive's successor will be out soon.

The Mushkin Chronos Deluxe 240GB has been in the $250 range for months, and that's not a bad deal either, especially on 5.xx FW. 32nm Toggle is good stuff.

In the ASU thread I posted some results from my CDx120 on 5.02 and got significantly different results than in the past, and its definitely worth the upgrade.

The chronos deluxe 240GB was at 200$ last week at ncix. But yes it's in Canada.

Too bad I didn't wait, I took it when it was 260$ 2 months ago!

Prices are going down, OCZ reports it sells SSD at 0.65$/GB.
