HP, one of the largest PC makers, has licenced its range of high-performance HP flash memory products. Why? To enable wider consumer use.
HP has licensed PNY (Est. 1985) to make HP Flash Memory products. PNY (short for Paris/New York) is US company and a leading manufacturer of Flash Memory Cards, USB Flash Drives, Solid State Drives, Computer Memory Upgrade Modules, Cables, NVIDIA GeForce Consumer Graphics Cards, NVIDIA Quadro Professional Graphics Cards, NVIDIA Tesla supercomputing inferencing cards, NVIDIA DGXTM Systems and PNY GPU powered servers and workstations.
The new products include USB 3.1 Gen 1 and dedicated USB-C OTG flash drives. They come in a range of formats including lanyards, keychains and more. Capacity ranges from 16GB to 1TB.
What is USB 3.1 Gen 1?
You can read more in our tutorial here, but essentially USB 3.1 Gen 1 is a 5Gbps (625MBps) interface.
UBS 3.0 is a similar overall speed as USB 3.1. But the reality is that this is a combined up/down speed and tops out at 3.2Gbps (400Mbps).
USB 2.0 has a 480Mbps (60MBps) speed that tops out at 280Mbps (35MBps). You can see why everyone wants faster USB Flash drives.
There are also other USB 3.1 Gen 2 (10Gbps), USB 4.0 (40Gbps – coming) and Thunderbolt 3 (40Gbps) devices.
What is OTG?
OTG (On-The-Go) enables a USB-A flash drive or USB-A device (keyboard/mouse) to connect to your phone or tablet via Micro-USB or USB-C port. You normally use a special OTG adapter, but more devices now include OTG capability.
A PC and USB flash drive works on a host/slave basis where the PC controls the drive. OTG changes that to the drive being the host and the Android (not iOS) smartphone the slave and vice versa depending on use – a kind of role swap. All you need to know is that you can attach OTG Flash drives to smartphones and read/write data from/to its main storage.
The current maximum OTG capacity is FAT32 2TB. Most OTG device have a USB-C and USB-A connector (to facilitate transfer to a PC).
Australian Review: HP flash memory products
A review of any flash drive is pretty boring. We wanted to see how fast HP’s premium x770 USB 3.1 drive was in comparison to the USB 2.0/3.0 ‘disposable’ flash drives.
Out test device was a Surface Pro 7 with USB-A 3.1 Gen 1 (5Gbps) and USB-C 3.1/2 Gen 2 (10Gbps) ports.
Crystal Diskmark 7 revealed some very pleasant surprises. Note the first two lines are sequential read/write of 1MB/1GB files (think restore/backup). The next two lines are random read/write of 1MB/1GB files (think loading or saving files).
HP 512GB x770w USB 3.1 (32GB-1TB) – not at JB or other retailers yet
It has a faster controller and can, in theory, achieve 400/250MBps sequential read/write speeds.
