ATP 150X ProMax 1GB SD

Examination:

With the number of growing products utilizing various flash media formats, whether it is a digital camera, MP3 player, cellular telephone, or Personal Digital Assistant, it can be difficult to find an appropriate card for your format. SD (Secure Digital) cards have been leading the way due to its petite size, low power consumption, high-speed data transfer, and write protect switch. Of course, looking at the ATP 150X ProMax 1GB it doesn't look like anything peculiar on the outside, in order to comply with Secure Digital format specifications, but on the inside are a few improvements to the construction of the ATP card in order to adequately offer the water, dust, and temperature proofing. However, on the outside of the unit is simply the ATP label across the topside of this blue-colored flash memory unit, while the left hand side contains the write-protecting switch.

In order to test the waterproof functionality of the ATP Electronics ProMax SD, we had completely submerged the flash memory into cold water, and near boiling water. Once the memory was descended into the water, we allowed it to rest for approximately an hour before removing the card and then drying off the unit. As expected, there were no problems with the operation of the unit after the water testing had occurred.

Performance:

For our ATP 150X ProMax 1GB SD testing, we stood by our usual slew of flash memory benchmarking. For read benchmarking, we used hdparm which is primarily used for getting/setting hard disk parameters under Linux, but can also specify meaningful numbers once the -t parameter is specified along with the drive being utilized. For our write testing, we used the Linux time command to record the length of time required to copy a 104.5MB file from the hard drive to the actual flash media. For results that are even more vigorous, we also timed how long it took to transfer 135 JPG picture files, with a total size of 106.2MB, from the hard drive over to the respective flash device. For the record, the 104.5MB file used was a Tape Archive GNU Zip (.tar.gz) of the 135 JPG files. All benchmarking of the Secure Digital card had occurred when connected to a USB2.0 Link Depot 21-in-1 Card Reader (LD-USR221). For comparison purposes, we have displayed the results from our four trial runs using the ATP Electronics 150X ProMax 1GB SD.
