Is there an internal HDD that will be as fast as my external HDD?

One of my computers has an SSD boot drive and an internal WD 2GB HDD for storage (photos, videos) that gets about 120 MB/s read/write using Atto to benchmark. Meanwhile, my USB 3.0 Seagate backup 2GB and 3GB drives get greater than 180 MB/s read/write using Atto. The "real world" performance is also noticeably faster with the external USB 3.0 drives.

My understanding is that the Seagate external drives use Seagate Barracuda HDDs, but when I look for reviews of those drives, they generally indicate transfer speeds well short of the 184-192 MB/s speeds I'm seeing with my external drives.

So my question is this: Can I use an internal HDD that will be as fast or faster than my current USB 3.0 external drives? Also, what is the fastest internal drive I can buy? Dependability is also important as these are my family photos, and while I have multiple backups (local, cloud, print), I want a robust primary copy. Budget is up to $250 per 2GB HDD.

Based on that, the Seagate Barracuda is tops. Are any of the enterprise HDDs like WD RE, WD RE4, or Seagate Constellation as fast as the Seagate Barracuda?

I have 3 of the 1 platter 2TB Seagates in my NAS and they will burst at over 200MB/sec. HDTune says that over their life span they are all 3 getting an average transfer rate of 146MB/s. I don't know of any non-SSD drives out there that are any faster than that.

If your External is getting sustained 180MB/sec it's a freak of nature.

sounds like his externals are dual drive raid0's and not single drive units. Nothing else is going to sustain 180MB/s+

That was my thought at first. Then I started thinking about how many USB 3 externals that I had seen running a RAID 0. Couldn't think of any. Does Drobo make RAID 0 units? Maybe he's just confusing peak with sustained transfer rate.

well seagate does have a drive that will do 180 peak but I didnt know they put it in an external. LoL

Amin - if you want a faster internal drive, get rid of the WD green 2tb drive thats in there and replace it with WD black edition 2tb.

Thanks, all. My external drive doing 180MB/s is just a regular Seagate Backup Plus USB 3.0. Was cheap too - $100 for the 2TB model and not much more for the 3TB one. I was basing my transfer speeds on Atto Disk Benchmark, so I can't say for sure that that's accurate...
