Do SSDs have frequencies or data transfer rates that one has to consider before buying?
Please tell me if this is write or wrong and why:
SSD are essentially flash drives, we have had flash drives for some time now and they are not that fast because of their USBB interface which is a bottleneck but SSDs will have a SATA interfaces which are a lot faster.
Of course you have to look at the read write specs of a ssd before you make a purchase.
#2 is right and you explained it yourself, it`s not a usb interface it`s a sata interface.
I don`t know why you think flash drives aren`t fast, I run Zorin, Ubuntu, and Linux off them and they fly :)
And if you install Windows off a flash drive it blazes.

Yes ate AddRam is on the money they are "flash memory" but come in very different build types than sticks do for example they have controller chips whereas sticks are just the chips - in a very basic way.
SSD's also have many other features such as self cleaning features and usually software from the manufacturer that you can use to Optimise and test the drive with. As for speed again as AddRam says my sticks are just lightning the 3.0 ones being slightly faster but not as much as is claimed.
The fact that SSD's again as explained are SATA connected and compared to USB faster and in my experience have it all over spinners even the so called SSHD ones (hybrids) which in my experience are not as good as claimed they are.
I use two brands of SSD's.
Intel and Samsung because they both have a great reputation.
Their are several test one can do or articles online comparing speeds of each. Doesn't really mean much in everyday usage.
For sure SSD's will run circles around hard drives of any kind.
Because I have only tried two brands I can only speak of those which have worked great.
I know of no slow SSD; some are just faster than others but you won't be able to see the difference. The difference you will see is between a SSD and a hard drive and you will be amazed.
I agree Layback there is no slow SSD even the Samsung 830 was not slouch. I have got Samsung (830 / 840 Pro / the 850 Pro and 850 EVO's , Crucial M4 , and perhaps the small 120GB SanDisk Extreme (one I overfilled) seemed to me to be the fastest though out here hard to find at a reasonable price.
So I have stuck mainly to the Samsung's and all the stuff that has been posted re speeds etc personally I think tends to detract away form the basically marvelous technology we now enjoy after all those years of putting up with those old clunkers though we still have to use them for the large capacities. The best thing about them are the rare earth magnets you can extract from them for keeping tools magnetized on the small racks I made out of them - for example - instead of having them stuffed away in drawers (the tools).
They do and one can, but I'd place more consideration on (in no particular order):
Included tools or toolboxes and their usefullness or issues.
Difficulty of returning to the seller if faulty.
Difficulty of returning to manufacturer if it comes to that.
Price
Warranty terms
Effectiveness and reliability of any included software, particularly migration software.
Apparent reliability of that brand and model, including design and firmware issues and how they were resolved by the manufacturer.
Form factor (if that matters to you and your motherboard supports multiple form factors).
Combined, I'd certainly place more emphasis on those named issues than I would on any speed benchmarks.
Yep I've been using mx100 series of crucial and they're pretty good,
Price wise are reasonable too :)
For the OS, the data transfer rate is of a lesser importance. It is the access time that counts.
The fantastic transfer rates that you see in the SSD specifications do not really apply for the OS operations. The OS deals with 4K records and the R/W times for those are a lot slower than for the large record sizes that are referred to in the specs.
The access time for most SSDs is in the 0.1ms +/- range and that is what gives you the performance boost. You can best check transfer rates and access time with HD Tune.

I own SSDs from OCZ, Intel, Crucial and Mushkin. The oldest are from 2008. They all work well to that date. My preferred make is Mushkin because I know they stand behind their products even several years after purchase.
Samsung
Intel
OCZ
Crucial (would not be my 1st choice)
Mushkin
PNY
Kingston
Corsair
As everyone has mentioned, a Solid State Drive will smoke a hard drive.
But you want one that is reliable and 100% healthy out of the box.
