I am deciding to get an external SSD for Window 10.
If I go with the eSATA route, what connector can you guys recommend?
If I go with the USB 3.0 route, what USB 3.0 SSD (<$70) and USB hub 3.0 can you guys recommend?

What is the speed of USB 2.0 (eSATA/powershare combo)?
Is the speed the combination of eSATA and USB 2.0?

The USB 3.0 of mine has "SS" on top. So, is the speed of it 625 MB/s?

Which of these is the fastest to transfer data to and from the SSD?
 
Solution
S
USB 3.0 has the better speed of the three. The SS mark just means it's 3.0

USB 3.0 - 5Gbps full duplex
eSATA - 3Gbps ? duplex
USB 2.0 - 480Mbps half duplex

Hi

Do you have a toshiba laptop?
Some have a esata / USB 2 socket

It will take a USB 2 connector
And possibly a special esata connector which picks up USB 5 V power not data

But this is only likely to support a 2.5" hard drive or ssd not 3.5" drive which also needs 12V



Esata speed depends on chipset and Sata port on motherboard it is connected to

On modern PC hardware USB 3.0 is more popular than esata sockets

If you are using SSD than consider this:

USB 3.1 (10Gb) support UASP, bus power <<==== my 1st recommend
USB 3.1 to SSD or 2.5 HDD adapter
USB 3.1 PCIe Host support Mac, Windows, Linux
USB 3.1 PCIe Host support Windows, Linux

USB 3.0 (5.0Gb) there are 2 version with and w/o one support UASP, bus power , Do not use USB3.0 non-supported uASP
with UASP - USB3.0 moves data in much more efficient

eSATA (6Gb - SATAIII) no bus power
eSATA (3Gb - SATAII) - no bus power
