I have my eye on a laptop ssd drive which lists 4200RPM.

 

Is this typical? Less desirable?

SSD drives have no mechanical spinning parts so no RPM.

It was customary at one point to try to make equivalencies between SSD performance and old HDD RPM.

 

That attempt is now pretty much futile.  See: http://www.seagate.com/tech-insights/choosing-high-performance-storage-is-not-about-rpm-anymore-master-ti/

 

It applies to more than just Seagate SSDs.

Here's the link: https://www.ebay.com/p/Crucial-M4-64GB-Internal-4200RPM-2-5-CT064M4SSD2-SSD/108236821?iid=112498431406

 

For this laptop, 64gb will suffice.. just wondering why rpm is listed.

It's an anachronism.   Old customs die hard.

So exactly on the drive itself does it say it spins @ 4200 RPM.

 

Can't really rely on an ebay poster.

Also, there has been a firmware update for this drive, see:  http://www.crucial.com/usa/en/support-ssd-firmware

 

This can also impact its speed.

Just sloppy labeling on the ad title, disregard the mention of RPM.
