Our second of three reviews covering the latest ADATA portable SSDs has us looking at the SV620.

While the SE730 carried a small form factor design similar to the T3 from Samsung, the SV620 comes in a familiar portable 2.5" form factor. Capacities offered for this solution include 240GB and 480GB while connectivity is pushed through USB 3.0 via its Micro-B connector.

ADATA touts this unit benefitting from the internal SSD with shock resistance, silence, and low power consumption while also having high performance. Performance marketing dictates 410 MB/s read and write. Further specifications show this solution supporting Windows, OS X, and Android.

The MSRP of the ADATA SV620 in the 480GB capacity comes in at $139.99 with a three-year warranty.

Up close, we have both the USB 3.0 port and activity LED above. Here, you can also see one of the design notes for the enclosure, that being the raised edge around the enclosure. This is said to prevent scratches on the main body of the enclosure.

To get things started, I opened CDI to see if this a custom-built solution or an internal SSD in an external shell. As you can see above, the SV620 uses a SP550 SATA SSD internally.

The first testing done was with file sizes and as you can see the SV620 does very well from 16M to 1M at 415 MB/s read and write then falls off slightly from 512K at 400 MB/s to 18MB/s at 1K.

Sequential performance reached 423 MB/s read and 422 MB/s write in CDM, while the same test at QD32 resulted in 388 MB/s read and 378 MB/s write.

Having the SV620 for a little while now, I'm quite surprised with its build quality. Even with this enclosure being a relatively cheap plastic, the drive has been able to withstand daily use and abuse. One thing I would enjoy with a device like this is a place to clip the USB 3.0 cable, as that seems to be the big downfall - I cannot find the cable when I need to use the drive.

As far as performance is concerned, the SV620 does rather well. With this now being the second week I have been using this drive, performance hasn't dropped much at all, still seeing close to 400 MB/s reads and writes. In testing for this review, we did see a peak of 422 MB/s read and write in CDM while our flash benchmark outlined the SV620's 415 MB/s read and write in 1M to 16M large file sizes. Random performance wasn't the best we have seen but was admirable at 28 MB/s read and 64 MB/s write or 7180 and 16,500 IOPS, respectively.

In closing, taking everything into consideration, the SV620 is a pretty good drive for those wanting a high capacity portable solution with bargain basement pricing. The ADATA SV620 480GB portable SSD carries an MSRP of $139.99 giving it a remarkable 29 cent per GB value.
