Strontium Nitro Plus evaluate

Strontium appears to have jumped into cellular storage in a giant approach. After our encounter with the Nitro iDrive for iOS, the corporate introduced our consideration to a few merchandise aimed toward Android units which assist USB On-The-Go. We have seen flash drives with Micro-USB connectors earlier than, however we have not seen an exterior card reader.

An growing variety of Android smartphones don’t enable storage enlargement, and a few older ones do not assist high-capacity microSD playing cards. Placing new knowledge onto a card and sharing massive recordsdata with others is typically a ache, requiring you to take your cellphone aside and pull out its battery or plug your cellphone right into a PC.

USB-OTG can turn out to be useful in a few of these conditions. Whereas a flash drive protruding of your cellphone isn’t any substitute for a tiny microSD card, it may be actually helpful. You’ll be able to retailer massive recordsdata equivalent to motion pictures that you do not want instant entry to on a regular basis, with out filling up your cellphone’s restricted cupboard space. You’ll be able to switch recordsdata between PCs and Android units and share them with pals. Most significantly, you may at all times make sure that your recordsdata are accessible it doesn’t matter what sort of machine you could have at your disposal.


Strontium Nitro Plus USB On-The-Go

We have examined dual-interface flash drives from Kingston and SanDisk within the latest previous, and this one isn’t any totally different. It is actually tiny, with a design that will not get in the best way an excessive amount of when plugged right into a cellphone. It helps USB on the PC aspect which is a big velocity enchancment over USB

The physique appears to be like metallic however looks like plastic. The gunmetal end is kind of good and did not appear as if it will put on off quickly. A big crimson Strontium brand and the capability of the drive are printed on the entrance of the swivelling lid. We acquired a 32GB unit for evaluate.


This drive could be very easy to lose – the corporate doesn’t present a lanyard or tag and there isn’t any hook so that you can connect certainly one of your individual. The 2 ends are just about at all times uncovered, so that you may wish to verify the bigger USB-A plug for pocket lint from time to time. Apart from these items, we’ve got no points with the design or development high quality.

We examined the Nitro On-The-Go’s USB speeds and located it to carry out fairly effectively. SiSoft SANDRA and CrystalDiskMark each reported constant speeds. Sequential learn velocity, which is the best-case situation for such drives, averaged at 144MBps which exceeded Strontium’s personal declare of 120MBps. Sequential reads had been after all slower, averaging at 26.68MBps. Random speeds had been measured at 133.71MBps for reads and 6.65MBps for writes.

Strontium Nitro Micro SDHC UHS-1 With OTG Card Reader
The second product we’re taking a look at is one thing fairly distinctive. It’s basically the identical form of dual-interface drive however with a detachable microSD card as an alternative of built-in flash reminiscence. This after all permits for added flexibility when copying photographs or making backups – each the cardboard and the reader could possibly be very helpful on their very own and when used collectively.

We aren’t actually impressed with the cardboard reader’s construct high quality. The plastic feels comparatively low-quality and the USB A plug is of the flat selection with uncovered contacts. A crimson LED shines by means of the underside of the physique when it’s plugged in. The unit is across the dimension of a typical flash drive if not longer, and will not be straightforward to misplace.


The microSD slot would not have any eject mechanism so you will need to pry a card out along with your fingernail, which is lower than superb. The bundled microSD card particularly was tough to take away as a result of Strontium has used an uncommon coating course of for its label which both makes it thicker than common or makes the grip on the top shallower. The print high quality will not be excellent and the label was simply scratched off simply by utilizing the cardboard in its personal reader. The general end reminded us of CD-Rs with stick-on inkjet labels which by no means look nearly as good as professionally printed discs.

Strontium advertises a free app known as MyBackup Professional, which it values at $four.99 (roughly Rs. 317). You may need to obtain it from Strontium’s personal website, which implies modifying your Android machine’s safety settings to permit apps from third-party sources to be put in.


When it comes to efficiency, we’re restricted to USB speeds right here. Strontium advertises the velocity of the cardboard as “70MB/s 466X”, although it is extra clear to notice that it’s a Class 10 card which ensures sustained speeds of 10Mbps and makes the cardboard appropriate for full HD video recording and bursts of nonetheless pictures. We recorded a mean sequential learn rating of 18.84MBps and a mean sequential write rating of 16.3MBps. Random reads and writes got here in at 18.28MBps and eight.25MBps respectively.

Strontium Nitro Plus Verdict

Each of Strontium’s merchandise provide cellular machine customers new and attention-grabbing methods to handle their knowledge. Of the 2, the Nitro MicroSDHC with OTG Card Reader is definitely extra versatile, however much less refined. We will not consider many conditions that decision for having an exterior microSD card reader helpful – maybe if it is advisable to copy a number of recordsdata between a number of telephones and/or tablets, a few of which do not have microSD card slots. We might have favored the product to have been higher constructed, and naturally USB would have been most welcome, but it surely nonetheless allows some attention-grabbing performance.

Alternatively, the Nitro Plus On-The-Go USB is plainer and easier, with a transparent objective. Twin-interface drives have gotten an increasing number of frequent, which is a good factor since you do not lose any performance in comparison with a typical flash drive. Finally USB Sort-C will make such merchandise redundant however till then we’re glad to have choices.
