SD Card Reader, WARRKY 7 IN 1 USB 3.0 Multi Card Reader Adapter, 3 USB 3.0, 5Gbps High-Speed Camera Memory Card Reader 4 Cards Reading Simultaneously for SD, SDHC, SDXC, Micro SD, CF, CFI, TF, MMC

This card reader is excellent for connecting several different types of SD cards.I have had no problems connecting micro SD cards or memory sticks.It saves a lot of hassle and is great value for the money.

I've come across WARRKY before, having one of their USB-C to HDMI cables. I like their aesthetic, good quality cable braiding and a focus on performance.This card reader shares some of the quality of other products, although the plastic casing isn't particularly high quality in this instance and the colour is more 'grey' than the picture would suggest.Aesthetics aside, the reader has a total of 3 USB ports and 3 card slots. At a technical level is it essentially a USB 3.2 Gen1 4 port hub, with the 4th port wired to the card slots. It also implements a backwards compatible USB 2.1 hub for older devices under the covers. The card reading is implemented by a Genesys Logic chipset.For cards, the USB3.2 Gen1 speed is potentially excessive, essentially the limitation will be the card itself, the interface speed of USB3.2 Gen1 is 5Gbps, which equates to 625MB/s. The fastest UHS-II SD cards peak at around 300MB/s. Although there is of course the possibly of reading multiple cards simultaneously, along with USB devices, thereby filling the available bandwidth.I tested a couple of devices in the reader.SanDisk Ultra USB3.0 32GB reported sequential read of 146MB/s and write of 54MB/sSanDisk Extreme 64GB V30 A2 SD Card reported sequential read of 89MB/s and write of 85MB/sAsides from synthetic benchmarks, everything feels snappy, even on drives and cards with many thousands of small files.For myself, I don't need the extreme potential speeds offered by this device, however, having recently upgraded my PC I've made a conscious effort to ensure all attached hubs, readers and KVM offer a baseline of 5Gbps speed - so as to not introduce any bottlenecks when hubs are wired in series. This reader fits the bill nicely.I've seen a few reviews unhappy with orientation of some of the ports, that is card and USB devices have to be inverted. I don't see this as an issue, I've had no problems inserting any card or devices into the reader.If anything the included LED is a little gimmicky, it doesn't really serve any purpose. It is supposed to indicate power, recognition and reading - but it's an unnecessary feature and not particularly clear. If you insert a drive and it works, it works - I suspect if it didn't you would just reinsert it.Pleased with this unit, will update review should longevity be an issue.

Does the job

All the alternative slots work and everything connected to the USB ports used so far has connected without issue.

At the moment I haven’t been able to try it but looks good anas seller sai

Needed a new one to download all my pictures from my camera cards after a shoot, don't like to use the camera as it means keep inserting and reinserting cards which is never good and a costly fix eventually.Nice unit, good build quality unlike some I have had that lasted a month or two, this look like its built to last, works fine, fast and cards go in and out easily, you dont feel like your struggling to fit them like some units.

Rien à dire, tout fonctionne bien, et c’est de l’USB 3.0, donc très bonne vitesse de transfert.Je recommande !

Come indicato nelle sue caratteristiche tecniche questo dispositivo ha diversi ingressi per le schede e tre per l'USB 3.0, praticamnete un HUB USB. Al momento l'ho potuto provare con schede SD e MicroSD ed è risultato abbastanza veloce, involucro in plastica leggerissima ma ben rifinita, led multicolore che indica il funzionamento in riposo rimanendo fisso rosso e lampeggiando blu e viola durante scrittura/lettura, cavo USB con rivestimento intrecciato., su Windows 11 funziona perfettamente, l'ampia gamma di connessioni lo rende estremamente versatile.

Für sein Geld bekommt man hier eine Menge Leistung. Das Teil funktioniert super. Das Kabel ist dazu 1. angenehm lang und 2. dick ummantelt.Wem die Optik wichtig ist, dem sei gesagt, dass das Gerät eher mittelgrau ist und nicht schwarz, wie auf den Produktbildern.

Necesitaba un lector de tarjetas más rápido en lectura y en velocidad de transmisión de datos, sobre todo fotografías. Este dispositivo lo es. Como dice en sus características técnicas, tiene diferentes entradas para tarjetas, y tres para usb.La velocidad depende de la tarjeta, pero va realmente bien.El único pero, sería que la carcasa de plástico no es muy refinada ni en color ni en calidad. Parece que la primera vez que se caiga se va a romper, pero el sistema de lectura es bueno, así que le daría un 4'8. sobre 5.
