comment How is it possible for SSD's drives to have such a good latency?
Where have you gotten the impression that the latency of NAND flash is so high?

comment Why do SSD drives get so much more expensive as they get larger?
@OliverSalzburg I suspect the biggest factor is that the kind of person willing to spend money on a 512GB SSD isn't the penny pinching kind in the first place. Or put differently, the people getting the biggest and best hardware aren't the price conscious. That said, I did see a Crucial m4 512GB for under $400 the other day, so prices are coming down.

-1 This answer is not correct in this size-range consumer SSDs. The 128GB to 512GB range all use the same controllers, just different amount of storage media. It is only once you go above 512GB that you have to start using more complex controller schemes.

comment Is it normal for windows to constantly write to disk
The Vertex 4 is based on the Marvell controller, but with custom firmware from OCZ. The issue is not present in that controller/firmware.

comment Virtual Disk Manager: The service cannot be started
There is no need to disable defragmentation on Windows 7. Windows 7 is smart enough to recognize an SSD and knows not to defragment it.

comment How come my Intel 520 180GB SSD performs extremely poorly?
@Willem Yes, for any video-related work any sort of SandForce is a bad idea. Not only does SandForce rely on compression to achieve high write performance (especially for smaller capacities), it also relies on the space left over for extra over-provisioning to maintain performance. Something that doesn't care that the data already is compressed would be a much better choice. As always, bigger would also be better.

comment Is it a good Idea to switch to a SSD to use less battery?
Standby for the SSD is essentially equivalent to everything from Performance Idle to Standby for the hard drive. So in a situation where the hard drive would be in Standby the SSD would also be in Standby, and in a situation where the hard drive would be in Performance Idle the SSD is in standby.

+1 This is the problem. The test uses already compressed data, which is a worst case scenario for the Intel 520 or any SandForce drive. For such data a Intel 510 or a Samsung 830 would be a much better choice.

comment Encrypt SSD before or after reinstalling Windows7
The Intel 520 has hardware encryption built in, which means it works differently from how general hard drives behave with passwords, thus making your reference not quite correct.

comment Is it possible to make raid 0 from 2 ssd drives?
-1 While it probably is cheaper to buy 2x 128GB drives instead of a 256GB drive, it usually is cheaper to buy one 128GB drive than 2x 64BG drives. No TRIM support is an universal issues, not limited to older models. There shouldn't be any drop in random transfers, rather an improvement in some cases.

comment Optimization Visual Studio build high frequency or number of cores
There isn't be any great difference between desktop and laptop CPU's. The laptop CPU's are slower as a group but the architectures are the same so the effect of clock-speeds vs core count is the same.

comment TrueCrypt full disk encryption on the Intel 520 Series SSD
AES-NI only speeds up the encryption. It will do nothing to help with the SSD dealing with the encrypted data.

comment TrueCrypt full disk encryption on the Intel 520 Series SSD
The Intel 520 drive relies on data compression and de-duplicaton the achieve high performance. If you encrypt the data with TrueCrypt it is no longer possible to compress or dedup it. This will significantly hurt the performance of that specific model SSD.

comment Troubleshooting slow SSD
Well, that implies you have NCQ enabled. I'm still unsure as to why you are limited to 200MB/s. AMD used to have issues with SSD performance but all that was sorted out in a series of BIOS and driver updates.

comment Troubleshooting slow SSD
The result for the small IOs (ie 0.5-32.0) should increase as you increase queue depth in ATTO if you have NCQ enabled. I'm sure there also is some setting in a driver or such you can look at but I am not very familiar with the AMD platform so I cannot help you there.
