SSD Performance over SATA to USB Adapter

Recommended Posts

I'm about to buy a 1TB SSD to boot/run an operating system (MacOS Mojave).  The drive will be run externally - plugged into a MacBook Pro (13" 2015 model) via a Sabrent SATA to USB 3(.1?) adaptor.

Given the performance constraints of USB and possibly the SATA to USB adaptor, does it really matter which 1TB SSD I buy?

For example I can buy an Adata SU650 series 960GB SSD quite a bit cheaper than a SanDisk 1TB SSD.  And a SanDisk Plus is cheaper than a SanDisk Ultra - but maybe USB cancels out all the performance benefits of the pricier drives.  Maybe performance is all so close that reliability is a more significant factor in making a choice here.

Any thoughts?

What exact drives are you considering for your purchase? We can throw things at the wall til it sticks, but focusing on what you're actually thinking about buying might be a more efficient use of time.

The cheapie SSDs often have very little RAM or use the 4-bit/cell flash and perform quote poorly in writes.

Make sure that your enclosure and host support UASP if at all possible.
