will it bottleneck?

[Harris]

so guys i have ssd kingstone hyperX 3k and my hdd are hitachi 1tbx2 sata2 3mbps/sec so will it bottleneck the ssd?

[Guest Generallee]

As long as the SSD is plugged into a Sata3 port on the motherboard

If you copy files to and from your SSD to HDD ~ it will create bottleneck.

wait" what do you mean?
so if i copy from my ssd to hdd iit will bottleneck? so for not bottleneck i should buy hdd sata 3 than?
why it is botlenecking ?

Look, a typical mechanial harddrive has a read&write speed of anything between 50-150mb/s and for ssds its typically around 450mb/s. A sata2 port is limited to a theoretical maximum of 300 if I recall correctly. Generally it performs a bit slower. So obviously a ssd will not live up to its full potential in a sata2 port unless you happen to have a bad one.

 

If you transfer data from a disc with a read speed of 500mb/s to a disc with a write speed of 100mb/s you will still be limited to the slowest. Same thing if you move files the other way.

 

Another thing to note is that mechanical harddrives are faster at the edges, meaning they work a bit faster when they are empty and slow down as they fill up. You can have some control in where you place your data by making partitions in order to make sure you save room in the fast area for things that make better use of the extra speed. A ssd however will slow down a little bit as it fills up and there is little you can do about it, although this slowing down is nowhere near as big as on a mechanical drive.

 

There is no "bottleneck" hardrives work independently of each other unless they work in some sort of raid configuration.

 

edit: sata2 and sata3 are different ports on the motherboard, sata3 also needs a different cable. However a sata3 drive will work in a sata2 and vice versa, but it might not work at full speed.

SSD's can read and write upto 500MB's (even thou there are a few that are faster), your standard hard drive even if sataIII will have read speeds up to 150MBs and writes of upto 80MBs

 

so lets say you have a ssd and a hard drive

 

lets say

 

hard drive read = 150MBs

hard drive write = 80MBs

 

ssd read = 500MBs

ssd write = 400MBs

 

lets say you wanted to copy a file from the ssd to the hard drive, it would copy at 80MBs because thats the maximum write speed of your hard drive, even thou your ssd can send that file at 500MBs

 

now you try to copy the same file from hard drive to ssd it would copy at 150MBs because your hard drive can only read at 150MBs

 

remember "you can only be as fast as your slowest component"

 

hope this helps
