They lied .... it has micron in it ... 25nm sync, NAND marked 29F32G08CBACA.Originally Posted by canthearu
Just opened the one I bought and checked
Nope, not even sync NAND. Just cheap boring asynchronous NAND. Might just turn on full incompressable and burn the drive to death!

I'm sorry, but I think I'm going to have to laugh for a minute.
Hey Ao1
Maybe I'm going about this wrong. Maybe the Octane needs a power cycle, like the first 830.
UPDATE
Oh my God. The Octane's MWI doesn't change when powered off, but the POH sure does.
Powering off the Octane resets Power On Hours. WTF??
Before
After
Notice the attribute in the first shot that has a raw value of 110? That's POH.
In the second shot it's back to 0.
WTF!

Wondering how long this Sandforce drive will last this time around ...
So I tried swapping the Octane into my SATA II ICH8M laptop... and it benched faster in seq writes. But after 40 minutes of endurance loops, speed dropped into the 20MB/s range. So something is going on. TRIM is enabled and working, but it almost seems like there is no TRIM.
And it was only doing 118MB/s max when I first started it anyway.
The Octane clearly hates my lappy.

Maybe if you rub off the OCZ writing on the controller, It will say Phillson ... like my Torqx 2, the Octane looks like it can't count hours or go faster then 20meg per second :P
This entertainment makes me feel a bit better about being ripped on the velox v30. BTW, the velox has the fixed firmware, sandforce version 3.3.2.
Back in the endurance rig, the Octane is doing half the average it was before. I put it in my laptop for an hour, and the speeds went down to 20MB/s. It's doing an average of 80MB/s at the moment, so it will either get better, or I'll have to SE it.
Had I just left the drive alone and not moved it to the laptop, it would still hum along as it was before (I believe).
And whatever the opinion of the Octane, it's surely better than a Phison. I liked it for the few hours I used it, but that's mostly because of the good feelings I have for the Intel 510. And the 510 and the Octane are just about the same.
Of course it is a better drive ... I was just having a little bit of fun.
In any case, the SMART values on the Octane are a write-off. I wouldn't expect any help from those figures in the future.
As for the intel 510, I'd love to give that drive a good endurance testing, but I'd find better uses for a 120gig Intel 510 before I could bring myself to sacrifice one.
I swill swear upon everything good and holy in this world that Intel designed the 510 for me because it seriously feels faster somehow. It feels faster than the Plextor M3P and faster than the 256GB 830. But if you just look at the numbers... It looks pedestrian. It should be seriously outclassed. But subjectively it feels blazing fast.
I don't take the SSD benchmarks too seriously. As long as it has good read/write latency and decent sustained sequential write performance, the SSD won't often be a bottleneck in a system. Even small 60gig SSDs with relatively poor sequential writes don't do too badly either most of the time, and only see any slowness when copying large quantities of data to them.
I'm not at all surprised the Intel 510 works as well as any other SSD despite poor benchmarks.
So I secure erased the Octane -- well, actually I just updated the FW again, which is just about the same thing. Speed went back to normal. It looks as though TRIM wasn't working on my laptop even though it was supposed to be, and that was the problem. When I put it back in the e-rig speed was slowly getting better, but still not good after 4 hours.
But I performed a little experiment.
I copied some data -- 18.6GB of my static data -- from the Samsung and Vertex Turbo while they were still doing loops. The Vertex Turbo's instantaneous speeds are ~94MB/s though the whole loop. While copying the 18.6GB of static data, instant speeds dropped into the mid-50mB/s range and I could only copy to the Octane at ~78MB/s.
The 830, on the other hand, saw no drop in instant speed when reading the 18.6GB folder to the drive. And it copied to the Octane at about 170MB/s.
Pretty awesome if you ask me.
Yeah, my Intel 520 sees very little drop in instant write performance during surface scans and data copying. (I throw the odd HDD Scan at the SSDs to keep them on their toes!)
Sad about the Octane's poor TRIMless performance though, it was supposed to have pretty decent garbage collection inbuilt.

This is what I'm talkin' about:
Since the the PE spec is half of what it should be, I think it should hit true MWI 0 at 10Kpe around 561,480GiB. This means I'd need to hit around 18,300PE cycles to get a PiB.

I’m starting to wonder if NDurance is simply a marketing gimmick with no substance. If you promote it as a beneficial product feature it seems strange that you would not want to explain anything about it. Still maybe the Octane will last forever and I am wrong.
That's because nDurance is probably the marketing name for ECC and wear leveling.

Performance under 100% incompressable writes seems fine ... though a bit slower then the normal 46% compressable run.
That's really not bad on the velox. The Mushkin only did 90mbs with incompressible data. That's only 20mb/s less a second than the super sexy Vertex... And the SF probably has a lot more overhead with incompressible data.

I have been reading this through in an attempt to learn more about the subject. Ordered a 520 for the real world test. Found OCZ performance upgrade that might be interesting or it might be old news.
Thanks all for the effort being put into this.
My Biggest Fear Is When I die, My Wife Sells All My Stuff For What I Told Her I Paid For It.79 SB threads and 32 IB Threads across 4 rigs 111 threads Crunching!!
The upgrade is the Arowana FW for SATA II Indilinx Barefoot drives like the Original Vertex and Agilities , but only ones with 34nm Intel NAND.
I also tried the new 502A SandForce Ref FW, and while this drive needs a SE badly, results are pretty good.

Looks like my velox v30 has life time throttling.
Performance down to 9meg per second.
May require resting this drive for a few months :/
