This hard drive can be an inexpensive extra backup drive for my MacBook Pro.

Yes. However, there is a 15nm drive inside: ST4000LM016 [seagate.com]

Good price OP. Smilie

Looks like lower write speed due to implementation to achieve higher density. Just expect slower write speed than a non shingle equivalent. From wiki.

Especially when the non shingled comes with 200gb cloud and is $87 max

I recently started using these, and have copied the contents of a number of powered external drives to these drives. I'm seeing 35 MB / second (is MB right?), which is about as fast as I ever see file copies happening. They seem as fast as any other external drive.

I've seen suggestions on SlickDeals that the 8GB SMR drives should not be relied up, for frequent reads, but I have not been able to corroborate that on a credible site.

Does that problem apply to these? I have my old big drives as backup -- but I'm doing a lot of reading from these drives.

TIA - Hoytster

I actually got this one instead that has 2 year warranty for the same price.

Price matched Amazon.com
https://www.amazon.com/Seagate-Po...segate+4tb

As a bonus, 200GB of free OneDrive cloud storage for 2 years is included when you register a new Backup Plus drive ($95US value)

Are you sure about that? I checked the Seagate site and the only 4TB 2.5" drive they list, ST4000LM016, uses standard "Perpendicular recording technology".

See page 5 of the product manual-

There's a whole lot of understanding "because I think it makes sense" before actually understanding. It's happens because, you know, we're on the Internet.

Reading isn't affected my SMR.
Writing _can_ be affected by SMR. Tests may show the drive is slow because they're designed from non-SMR drives. There's a large cache in SMR drives because the writing, inside the drive, is slow. Because of the cache, writing to the drive is not slow.. Unless more is being written that the cache can hold. Write 20GB to the drive and it'll seem normal. Write 40GB to the drive and it'll seem normal for a while, then slow down to a very low speed.

Short story, if you write huge amounts of data all the time all day you don't want SMR.

As far as I know, there is NO mechanical hard drive that comes anywhere close to saturating a USB 3.0 bus.
