eSATA Vs USB 3.0 are two competing information transfer ports that have recently been updated to provide even greater performance. In the following guide, I examine the most recent edition of eSATA using USB 3.0, so you can determine which will be the ideal alternative for your personal computer or external storage device.
In the last couple of decades, we’ve seen a proliferation of the amount of information transfer interface technology. Users purchasing new external hard drives and other mobile electronics confront a problem of lots with USB 3.0, eSATA, FireWire, and Apple’s Thunderbolt producing an entrance to the marketplace. With every offering data transfer rates in multiples of gigabytes per second (Gbps), the average user can find it exceptionally confusing to make a selection.
Utilizing this Techspirited essay, I will make a choice somewhat easier by comparing USB 3.0 using the most recent eSATA variant. From the time you’re through with this guide, you will understand which technology could be a superior alternative in the long run. Allow Colorfy to provide a brief summary of the two technology before comparing both.

eSATA Vs USB 3.0
In general, most topical and mobile hard drives are equipped with USB ports. A few external hard drives include different vents such as eSATA, Thunderbolt, etc.. I’ve discussed Thunderbolt external hard disk. In this particular post, I mostly concentrate on ESATA vs. USB 3.0.
What’s USB 3.0 Port?
USB 3.0 is a USB data transport protocol initiated by companies like Intel, which can be used with USB 1.1 and USB 2.0. In comparison with USB 2.0, whose transport speed is 60 MB/s (480 Mbps), the transport speed of USB 3.0 could be up to 500 MB/s (5 Gbps).
USB interface includes many physiological forms like USB Type-A, USB-Type-B, USB-Type-C, Micro USB, Mini USB, etc.. Nonetheless, your desktop computer or notebook computers are mainly utilizing USB Type-A and USB Type-C ports. In contrast, external hard disk drives are mainly utilizing USB Type-A (this interface is more commonly utilized in 3.5-inch drives), USB Type-C, Micro USB, and Mini USB interfaces.
USB 3.0 protocols can operate on all of the physical USB ports mentioned previously, therefore do USB 2.0 protocol. Therefore, before buying an external hard disk, please consult customer support to ensure the disk supports USB 3.0.

The physical eSATA interface is revealed as the following image:
Like the SATA port, eSATA speed could be up to 600 MB/s (6 Gbps) at most (older variants’ speed only reaches 150 MB/s or even 300MB/s).

eSATA Vs. USB 3.0 – Which Would You Use?
SuperSpeed USB 3.0 gained a great deal of popularity this season by launching countless fresh USB 3.0 apparatuses and tens of thousands of USB 3.0 gadgets nevertheless en route. Not, which USB 3.0 itself is all that fresh, considering the specification premiered from the USB-IF back in November of 2008. Nonetheless, it’s accumulated enough focus we thought we would have a peek at how it stacks up against one of its fiercest rivals – eSATA technology.
These days, eSATA can handle around 300 MBps (Megabytes per minute, while USB 3.0 cranks up a notch up to 625 MBps. Here’s a Simple number breakdown:
- USB 2.0 – maximum bandwidth of 480 Mbit/s
- USB 3.0 – maximum bandwidth of 5 Gbit/s
- eSATA – maximum bandwidth of 6 Gbit/s
USB 3.0 dominants USB 2.0 running at greater than five times its greatest rate, and eSATA is a bit quicker than that. So that makes eSATA the winner. Well, not very. From the conflict of information transfer technologies, it isn’t about who is the quickest. Let us take a good look at each of those interfaces and determine how they rank up against each other.
ESATA is the outside version of the SATA technology. Your computer is currently using SATA because of its hard disk. While both eSATA and SATA are older than USB 3.0, its proponents would nevertheless assert that it is far better than USB 3.0.
A lot of individuals may still assert that eSATA is most frequently used for the external hard drives. On the interior, hard drives are still using SATA technologies even when you’re linking your pc with USB or FireWire over the exterior. These devices need to use a bridge chip to interpret the ATA protocol to USB or the FireWire IEEE 1394 protocol.
There are two ways that this is completed. The first would be to encapsulate the SATA protocol information into USB or FireWire. Another would be to convert the information into one of those outside information transmission protocols. In any event, this will wind up having many additional steps and processing, which end up slowing the effective throughput.
Various benchmarking tests confirm this claim. Specifically, eSATA had been proven to be a whole lot quicker than USB 2.0.
Nowadays, it is an entirely different ballpark. USB 3.0 SuperSpeed 5 Gbps is over ten times faster than USB 2.0 top theoretical speeds of 480 Mbps. USB 3.0 also supports data transfers that are asynchronous, meaning that unlike USB 2.0, it does not need to wait to survey a USB device every time it needs to begin sending info one way or another.
USB 3.0 also introduced a brand new transfer method named Bulk Streams. With this transfer process, USB 3.0 can currently support several data flow transfers at the same time. The web consequence of this is that the protocol will do better with bigger data transfers like the ones demanded by watching a 1080p movie that is being stored in an external hard disk. USB 3.0 must take care of the SATA to USB protocol conversion lag on external hard drives.
So who is the real winner when it comes down to raw read and write rates? In all honesty, there is currently no real response to that. There are nevertheless some demanding benchmark quotes you may make an educated decision on. With an external hard drive, USB 3.0 is generally about 20 percent quicker than eSATA at reading rates, while eSATA was roughly the same percentage quicker at writing information to the disc drive. This is an overall idea about what you may expect from eSATA and USB 3.0 now but by no means a definitive standard evaluation.
In all those instances, the results were much lower than what was due to them. With reads, the USB 3.0 drive averaged out in 90 MBps, although the eSATA push ended at 75 MBps. The eSATA was still processed at approximately 75 MBps with write speeds while the USB 3.0 fell to 62 MBps.
This type of gap between the actual world outcomes, along with their calculated theoretical outcome, is, in fact, quite common. Most devices you have don’t function as quickly as they claim they operate. As technology progresses to maximize the rated output on USB 3.0 and eSATA, these performance evaluations will considerably improve.
USB 3.0 does provide a few fantastic benefits over eSATA. Contrary to USB 2.0, you can power devices via a USB 3.0 link, as you will need another electricity connection for an external eSATA device. Thus the power cartridge present on many eSATA external hard drives.
USB 3.0 also manages around half more electricity compared to USB 2.0, but in a means, this is sort of a letdown. USB 3.0 devices tend to drain your notebook’s battery a great deal quicker than USB 2.0 devices, but many say that this should continue to improve with later versions.
Another very great incentive for USB 3.0 is that USB 3.0 is backward compatible with USB 2.0 wires and apparatus. You might even use USB 3.0 wires and apparatus on older devices with USB 2.0 interfaces, but they will run at lower rates.
If it boils down to the cable, USB 3.0 is still too new to be raving about it just yetto accurately judge it from other data transfer procedures. We may expect that technology to transcend eSATA in every facet finally, but we are simply not there yet. I would expect by next summer, nonetheless, that computers and peripheral devices come using USB 3.0, phasing out the popular USB 2.0 and its worthy rival eSATA.
So which would you use? If you are worried about distributing your data from PC to PC, then USB 3.0 is undoubtedly the winner. Even when the PC or Mac you link to has old USB 1.1 or USB 2.0 interfaces, the peripheral will probably connect and transfer information, albeit at a much lesser speed. If you’re worried about storage, particularly for job projects connecting to one PC, then eSATA is a completely valid option. You might even find it quicker than USB when you’ve got a good deal of additional USB devices on the PC at precisely the same moment.
