4.0 out of 5 stars Sony MSMT4G 4GB Memory Stick PRO Duo (Mark2)

2026-02-23    -Bill

Got a good price for this Sony MSMT4G 4GB Memory Stick PRO Duo (Mark2) and have been using it with a Sony DSC-W300 with no problems at all. Works great and has been reliable so far (about 2 months usage) in and out of the camera many times. It came with a Memory Stick to SDHC card adapter to plug into PC's that only have an SD or SDHC card slot. I use the adapter to upload pics to my laptop and it works fine. However the transfer speeds are slower than using SDHC cards or Compact Flash cards. I don't know why Sony won't admit they have the inferior memory card format and just switch over to SDHC format! Other than that this stick is working fine and all my older Sony memory sticks and this newer PRO sticks have been reliable.

Even though I have been slowly weaning myself off of the newer Sony cameras, I still have some Sony devices that need memory pro duo cards. There are some advantages and a few disadvantages, namely the cost and availability. Sony's memory format averages 30 to 100 percent higher prices for the same capacity of SDHC cards. While that sucks, if you have a Sony Camera or a PSP there's not much you can do about it.To that point, both the new Sony Cybershot DSCT300 Digital Camera and upcoming PSP God of War Entertainment Pack will benefit from any of these memory cards. Both of those devices, along with most Sony devices for that matter are only comaptible with the memory duo platform.But like I said, if you need one of these cards, there are some advantages especially if you get a Mark II card. Namely, the performance speed of the mark II format is about 50% higher than the fastest available SDHC card at the moment. The rating is for 36 MB/s and what I've seen through some basic tests seems to indicate real performance close to this. In fact, the solid performance has to be the biggest pro for these cards. So while it sucks to have little choice, when you factor in the premium performance it's easier to swallow.The 2 and 4 GB cards are a better value than larger capacity ones right now. Sometimes you want the largest card you can get, but till the 8 and 16 GB cards come down I see no reason to buy them. Not to mention, this isn't for my primary camera but for an older one that I use as a backup.Make sure your device is compatible with the card. Some older electronics aren't compatible with larger capacities, although in general Sony has been better with making these guys backward compatible than others.It's always a good idea to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card may be worth it if the price is right. Or you may want to step up to the larger 16 GB size that is now available. But if you wait a little longer you can save yourself some cash. I have to take off at least 1 star for value, but in terms of performance I couldn't be happier.

The memory quality was very good as well as speed

5.0 out of 5 stars Best Price for the Sony Pro Duo is Found with Amazon Sellers

2025-12-23    -DeltaLady

We purchased this from Amazon Seller ABX ProTECH as it was being sent to our son and daughter-in-law on the East Coast (and ABX ProTECH is located in New York). As we wanted First Class shipping, we found this Seller to be closer and indeed, the product arrived only three days after we ordered it.We had purchased a Sony CyberShot camera on Amazon for them for their anniversary and they had talked us out of getting the Memory Card/Stick as they were sure they could find one locally. However after being sold two incorrect ones by their local Best Buy, on the third trip they were further frustrated to find that Best Buy wanted TWICE as much for these as Amazon. As I had offered to get them one to begin with, I immediately ordered it from ABX ProTECH on Amazon and they had it in an amazing three days, in time for their snowy southern weekend.Sony is like Dell, they design products so you must use brand-specific accessories, etc., with them for optimum results. My son did not want me to down-rate the camera (as others have) due to this as he stated it is just "good old capitalism." While it can be a pain at times, and also more expensive at times, we have used Sony cameras and camera products for years, and have had excellent results.However if you need one of these to arrive in a reasonable amount of time, I advise shopping around the different Amazon Sellers who carry these and find one who is closer to you to overcome shipping time. Many of them are within a few cents of each other in price (when you figure in the differing shipping costs) and the ours arrived at our son's home much faster than it would have if we would have purchased from a Seller on the West Coast.All in all, our son and daughet-in-law are happy with it, so we are happy with our purchase. We are also MORE THAN DELIGHTED with the prices for these found with Amazon Sellers!

I have a 2009 sony handycam, it ONLY takes a memory stick pro duo. Holds the amount of video I need for my vlogs. Will definitely try and buy more of these.
