More interesting is why Samsung do this……

If disabling “Enable write cache” makes no difference to performance that is one clue. Intense random 4K write activity will also make the DRAM get very hot, which is another clue.

^agreed. With PC sales dropping it’s not really surprising that R&D on new technologies is being impacted. Current PC performance is also well in excess of what most people require so that incentive is also lacking.

The thread title does not say failure rate and neither do the posts, but I am intrigued. Most retailers check RMA goods and if no fault is found they are sent back to the customer. I don’t know if the statistics are based on RMA’s that have a verified fault or if they include no fault found...

Can you use AS SSD Benchmark? No need to run the benchmark but if you open the app and select the drive of interest it will tell you if the drive is aligned and what drivers you are using.

Start the PC with the problem hard drive connected and then put the PC to sleep. Whilst the PC is in sleep mode swap over the circuit board. When the PC wakes up you “may” be lucky and able to read from the drive.

Of course this only provides an insight and not necessarily the full picture, but as most manufacturers won’t publish RMA rates the analysis by Hardware.Fr is very helpful and by and large it does not seem at odds with other sources of information on RMA rates. As for sample rates that...

Taken from Hardware.Fr, translated via Google (not perfect but readable). http://www.hardware.fr/articles/893-7/ssd.html SSD - Samsung 0.05% (against 0.48%) - Plextor 0.16% (N / A) - Intel 0.37% (against 0.45%) - Crucial 1.12% (against 1.11%) - Corsair 1.61% (against 1.05%) - OCZ 6.64%...

Maybe he is getting confused by the fact that OCZ bootable tools are based on Linux :confused:

Forulav8 says he has the speed issue on all drives including an Agility 3, which uses a SF-2281 controller and 25nm Micron NAND. As NAND is the most expensive part of a SSD it would not make sense to swap NAND over and in this case it’s 25nm anyway. It’s much more likely that a SSD...

lol they are all over the net. Goes to show how many RMA’s OCZ get. They should perform the same as a new drive however as the specs have not been changed. If they don’t you could open one up to see what NAND is being used, although you will invalidate the warranty by doing so. OCZ...

Where are you getting the refurbs from? Direct from OCZ? Have you opened up one of the SSD’s to see what is inside?

Cheez, you have the worst SSD for the workload you are applying. HDD’s are great at seq writes whilst the OCZ Sandforce drive is not as it can’t compress the data. If you are only comparing non compressible writes then sure your HDD array will be faster. If you had a good SSD that could provide...

Not wishing to fan any flames, but here is a simple explanation. “Service time” measures how long it takes to process a specific request “Queue time” represents the amount of time a request waits for service “Response time” = service time + queue time As...
