Fastest Read/Write Speeds of a 1TB SATAIII/6Gb 3.5" Interal HDD?

[BAD311]

Every time I look up SSD drives on Newegg and other sites I clearly see the read/write speeds of the SSD drives... However on internal SATA drives, or even older IDE, I've never noticed the read/write speeds of the drive...

So the question is...

What is the fastest read/write speed of a 1TB SATA 6Gb internal HDD?

I know the spin speeds are 5400, 5900, 7200, 10000 etc... but the read/write?

I want to really understand the speed differences between HDD and SSD units

Thanks!

the fastest HDDs sequential read/write speeds will fall around 100-140 MBs for large file sizes. Random 4k reads/writes are going to be around 1 MBs.

Regular HDDs will be used for some time for raw storage. Just like capacities have been steadily increasing so have their speeds.

Thanks Mark, that's a impressive difference vs. SSD!

yeah.. many get confused by the theoretical bus/channel speed of sata3 when it comes to capability of sata3 HDD. They should be using different terminology for HDD's, IMO. More like "sata3 compatible".. NOT "sata3 capable".

the website storagereview (www.storagereview.com) has a large performance database of HDD. It does show that the drive has progressed well over the last several years.
