trovato i dati di scrittura/lettura?

[fed_cas]

Ciao, dati ufficiali non sono riuscito a trovarne ma ho trovato un utente che ha fatto dei test. Riassumendo per non essere una scheda ad alta velocità tipo le sandisk ultra o extreme è piuttosto veloce ;)

Speed

I was unsure of the kind of speed this SanDisk card can provide. I was unable to find the information about its speed on the SanDisk's web site or in product descriptions on web sites that sell them.

There were two possibilities. The more likely one was that the car is pretty slow and the manufacturer does not disclose its speed because people would not buy them knowing how slow the card is. The other, less likely, possibility was that the card is so fast, it would compete with SanDisk's premium lines of memory card that are more expensive but probably offer nothing more that faster speed.

To try out, I put this card to a test in my Panasonic FZ5. For comparison purposes, I used both the standard speed (slow) Kingston 512 MB SD card and the fast Kingston Elite Pro.

When shooting JPEG files (1-2.5 MB each), there was no difference if I was shooting at intervals of about 2 seconds. But if using the burst mode of my camera, there were less delays with either the SanDisk or the Elite Pro than with standard Kingston.

And in TIFF more with file size of 14 MB, the Kingston standard took 15 seconds, the Elite Pro 3-4 and the SanDisk only 4-5 seconds per image.

This means that it is much faster that standard Kingston SD card (rated at up to 1.5 MB/sec write speed) and is close to Elite Pro (rated at 7-8 MB/sec). At least in my camera, this (supposedly standard) SanDisk card delivers write speed of at least 3.5 MB/sec. And since the camera is probably limiting factor, the speeds that can be achieved in a faster-writing camera or a fast USB 2.0 card reader will be even better.

I recently got a card reader (Dazzle 8-in-1 USB 2.0 Hi-Speed) and did some speed tests with this card. It was able to srite a 151 MB of files on it in 55 seconds, which amounts to almost 3 MB/s.

The read speed was even faster (I removed and reinserted the card to make sure the files were not cached). I was able to read 151 MB in 30 seconds, which amounts to 5 MB/s! Pretty good for a non-speed rated card.

Since this card is so much faster than my standard Kingston, I am getting rid of it and keeping this SanDisk card.
