comment Do I need to do something about partition alignment when installing Windows XP on a SSD drive?
Windows 7 uses the same alignment for both HDDs and SSDs so as long as you let Windows 7 align the HDD the alignment should be preserved during migration.

comment Why can't I launch telnet.exe from a Windows 8 command prompt?
I start telnet in Windows 8 the same way I did in Windows 7: Hit the windows key, type telnet, hit enter.

comment USB 3.0 slower than SATA for SSD
@Luke That's just it. You are not giving theoretical maximums for any of them. For USB 3, SATA 3 and 2 you are giving electrical signalling rates, which are higher than theoretical maximums transfer rates. For USB 2 you are giving the theoretical worst-case, which is not the theoretical maximum either.

comment USB 3.0 slower than SATA for SSD
@Luke Your not really answering the question either since even though USB 3.0 is slower than SATA 3, the USB 3.0 numbers you are giving are still faster than what OP is seeing.

comment USB 3.0 slower than SATA for SSD
@Luke Your USB 2.0 numbers are still incorrect. If you both read and write over USB 2.0 at the same time you do end up cutting bandwidth in half, but doing it only one way you don't. Your 30MBps is still slower than what you can see in real world USB 2.0 benchmarks, like here: images.anandtech.com/graphs/graph6089/48168.png

comment USB 3.0 slower than SATA for SSD
-1 This is not correct. USB 2.0 is half duplex, meaning that it can do full 480Mbps (not accounting for encoding) in either direction. It just can't do it in both directions at the same time. USB 3.0 support full duplex, same as SATA so it can do full speed in both directions. Also, the actual speed of SATA 3 once you account for 8b/10b encoding is and the prefix mess is ~572MiBps. This compares to USB 3.0s ~458MiBps.

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.

comment Why do SSD drives get so much more expensive as they get larger?
-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.
