Series: Suite Memories

"Memory Stick PRO-HG" is a flash memory media developed by Sony and Sandisk.It is characterized by a high -speed transfer of 30MB/s, about 3 times compared to the conventional memory stick Pro.

The speed of speed is that the terminals are expanded from 10 pins to 14 pins and four data rays are added.In the past, a 4 -bit parallel transfer was doubled by 8bit parallel.In addition, the data clock is 1.5 times by improving the data clock from 40MHz to 60MHz.The total speed is tripled.

This is only among successive memory sticks that the number of terminals is increasing physically.That's why the memory stick Pro-HG is the most changed series.

The size of the memory stick PRO-HG is only a small DUO size, no standard size.Also, smaller microsizes (M2) are standard, but did not appear as products.

So, it is the appearance of the model that first appeared, the model number that started with "MS-EX".

At first glance, it seems that there is no difference from the conventional product, but in fact, the dent at the right end has increased to two.When I checked when the dent peculiar to DUO was there, the first "Memory Stick" was added, and a dent was added from the second generation "Memory Stick (Magic Gate/High -speed Data Transfer)".

Or rather, I know that there is no dent in the first generation ...

Anyway, the feature of the memory stick PRO-HG is that there are two dents.

Let's look at the back.

To see that the terminals are increasing, a memory stick (magic gate/high -speed data transfer compatible) is arranged on the right for comparison.

Four pins (counted from the right 3, 4, 5, 7) are assigned to the data, but you can see that this pin is divided and extended to eight pins.It is also a big difference that the terminal is slightly longer than the conventional memory stick.

This memory stick PRO-HG has three generations in the HX series (MS-HX series) as a successor model as well as the first MS-EX.

The color and design of the label have been changed, and it features HX letters.

From left, MS-HX (2008), MS-HXA (2010), MS-HXB (2011).If you look closely, the way of making the package on the leftmost MS-HX is different, and it looks like the label part is square, like the first MS-EX.

Although it is a state of high difficulty, there is a large difference in the nominal speed of 20MB/s for MS-HX, 30MB/s for MS-HXA, and 50MB/s for MS-HXB.In the end, although it is speeding up, I wonder why the speed is decreasing with MS-HX.

By the way, in 2008 when MS-HX appeared, the SSD used in the PC was not SLC, but multi-value MLC became mainstream.In MS-EX, the speed that was "data transfer" was changed from "Read out" in MS-HX, so I wonder if it changed from HX series to MLC.

There is no big difference on the back side, but if you look closely, the country of manufacture was different.The feeling of catching the photos of the personal trading site did not mean that the country of manufacture was determined by generations, but it seemed to be mixed with Japanese, Korean, and Taiwan.

By the time the memory stick PRO-HG appeared, it was already pushed by an SD card.Compared to SD cards that can be used by many manufacturers and equipment, memory sticks that can only be used with Sony products would have been strict.In 2010, the Condigi Cyber Shot Series has finally supported SD cards.

Due to these changes on the device side, the general memory stick was stopped by this Pro-HG.

Memory stick Pro-HG HX (MS-HXB) is still on sale.The maximum capacity 32GB costs 17,600 yen, but it is thankful for those who continue to use old equipment to be able to purchase 10 years after its appearance.
