I have a spare 4GB ADATA C906 USB2 stick, NAND is Micron 29F32G08CBACA, 10th 2011 manufactured.. I guess it's 25nm 3K P/E asynchronous..

Stupid question perhaps but here goes anyway;

Looking at the charts in post 1 can I assume that if a given 60Gig drive reaches MWI in xTB written then the `120Gig version of the same drive should hit MWI in 2xTB and the 240 in 4xTB etc?

This is mostly true for most drives. Most drives use average PE cycle count to determine MWI 1, meaning a drive with flash rated for 5K PE cycles will consume 1 percent of MWI every 50 PE cycles. The 64GB Turbo I ran used 1 PE cycle for every 56GB written, so for every 2800 GiB written in the test the drive would reduce MWI by 1.

Some drives, like the M3P and the Octane, rely on reallocations to determine MWI, meaning MWI will never decrease until there is a block failure.

So after 7 days I put the drives back in the endurance rig. Both drives' average speed is down by 5MB/s, and current speeds never quite get as high. Even with all power saving technologies disabled and on the same RST version, it's just not as fast. Almost, but not quite.

[AMD_Freak]

same MB or different?

[Christopher]

same MB or different?

Different. All other things being equal, different MBs have slightly different performance (even on 1155).

As competition to Anvil's Intel 330, I present the Sandisk Extreme G25 - 120gig.

Sporting 128gig of 24nm Toggle NAND and the sandforce controller, Sandisk has created a little ripper of a drive at a very competitive price. Unfortunately, due to the nature of the sandforce controller, and the configuration of NAND in this drive, speed will be a little bit slower then the Intel 330. However, it is also a bit cheaper, and can be gotten in larger sizes then the intel 330.

Initial SMART values


Benchmarks



Running ASU endurance test


Notes: I does appear that the sandforce controller can manage bad blocks .... loading the initial data on the drive caused a couple of bad blocks to appear. This drive must have escaped the factory before it's bad blocks where fully found.

Edit: I am using same specs as other drives, but have 64gig of static data to match Anvil's 330.

[Anvil]

The Sandisk Extreme should be very interesting vs the 330

I had expected the Extreme to be a bit faster than the Intel, having said that, I'm positively surprised by the performance of the 330.

Corsair Neutron could be the next one to test, scheduled to be available in July. (new controller)

Well, the Intel 330 isn't using RAISE, so the sandisk extreme g25 has to work harder during writes ... that said, I'm getting about 120meg per sec speed, so it isn't a lot slower.

Out of the box reallocations are seldom positive. Is the 120GB Extreme using 64gbit dice?

[Anvil]

Well, the Intel 330 isn't using RAISE, so the sandisk extreme g25 has to work harder during writes ... that said, I'm getting about 120meg per sec speed, so it isn't a lot slower.

That's true, otoh the 330 is said to be using 6 channels. (6 out of 8)

I'll update post#1 with the new contestant.

The 330 is using all 8 channels on the 60/120s.

I suppose it's possible be that the 180GB is only using 6 channels with 4 way interleaving, but the 180GB 330 is also different in that it's using "redundancy" (ie Intel RAISE), not found on the other models.

All in all, the 330 is pretty excellent IMHO, I'm curious to see if the 120GB happens to last forever too.
