Overpriced proprietary memory card

It works just fine, but this is one of the frustrating failures that makes the PS Vita the obscure failure of Nintendo's 3DS.

You can buy this item from several different sources.
It's likely made in China and any PC supplier/store can have whatever brand-name they want stamped on them.

Mine showed low-quality workmanship and was defective (would not allow writing to card).

If you're gonna buy one, better buy half-a-dozen to ensure that you get at least a couple that work properly. Don't pay more than a buck a piece.

IT's the SPEED stupid!
I have tested a Targus SDHC card reader available at Walmart for $8.88 and found it to be much faster than the above and much faster than the Topram CF-RS208 which I also recently purchased here. Being able to write a file faster is something you DO & WILL want. Also you can fast-forward through a stored video at a higher speed with a better quality card reader.

Not very happy. The memory is not user-upgradable and HP won't help me with it. So it is going to cost me $150 to install $35 worth of memory.

I have used three of these cards (32GB) for tens of thousands of shots in my Nikon Professional cameras. In all that time I've only experienced problems once (recently a few raw images were missing from one of the cards - the JPEG thumbnails were there). There is a limit to how many times these (or any) camera memory cards can be written to, so perhaps one of the cards is starting to fail as it approaches the end of its useful life.

With that in mind, I started shopping for some new SanDisk Extreme 32GB CF cards. When I saw that Amazon itself is not selling these -- but that one of their "Marketplace" sellers is, I checked with B&H and also on the SanDisk website. I discovered that these black cards on the Amazon.com website are NOT the current version of the SanDisk Extreme 32GB CF cards. The new version of the SanDisk Extreme 32GB CF cards are GOLD. Instead of 60 MB/s and UDMA, they are now 120MB/s and UDMA7. Also, the price at B&H for the new version is only $4 more than this seller is selling the old cards for.

I purchased this Sandisk 16gb MicroSDHC Class 4 Card from Everything But Stromboli.  It looks good. :)

I used Crystal Disk Mark 3.0.1 to test the speed.  I was particularly interested in the Random Write 4KB (QD=32) for my Optimus T and Nook Color.  I also ran H2testw to test the actual size of the memory card. Below are the results of the tests I ran.

Luckily, I had transferred my 700+ pictures off a non-KomputerBay 32GB memory card via the digital camera before trying out the SD USB reader.

In doing so, the Windows 7 Pro machine displayed a file listing of the files, but when I attempted to copy them off the memory card, the system warned me that I needed to format the "drive" in order to use it.  I canceled the formatting and removed the SD memory card and plugged it back into the camera for reading.  Upon turning on the camera, it too said that I needed to format the memory card.  At this point, the memory card was unreadable and required formatting in order to use on the computer or the camera.

I can only conclude that somehow, attempting to use the SD USB reader corrupted the memory card, thus rendering the memory card unreadable - I'm now unable to trust the included SD USB reader and will unlikely use it in the future.  I'd say it's not worth the extra $ for a SD USB Reader that you can't trust.

I'm also hesitant to trust the memory card in my digital camera as well and will unlikely buy another KomputerBay product.  Too bad - the prices are very compelling.

Like everyone else, and I'm sure common sense dictates to you, I knocked off stars because this product is absurdly overpriced. Even with nearly 20 bucks knocked off the MSRP when I bought it, it is hard to stomach. I kept waiting, and waiting and waiting for a price drop on these cards to happen. I've been dealing with a 4 GB card as long as I've had my Vita and it just doesn't work if you have more than a couple digital games and a few cartridge based games that need updates installed. I love having the space and not having to shuffle the games around anymore using Media Manager (I'd forget about games all the time because they'd just be out of sight out of mind on the hard drive of my computer). It does it's job, so 5 stars there...price is abysmal. Minus two there.

There is nothing "Ultra" about this memory card. I purchased four of these to use in a couple of dash cams I purchased  for my cars. Shortly after installing the cameras, I began to have issues with the cameras shutting off intermittently. After spending a lot of time with tech support, I figured out that this memory card was the problem. It turns out that this memory card is not suitable for use with a dash cam. Nowhere does it mention that on Amazon. I replaced all four of these cards with 32gb Transcend High Endurance cards and the problem went away, so I'm out over $60. DO NOT PURCHASE THIS CARD FOR USE IN A DASH CAMERA.

I've purchased two (2) units of the Topram 16GB SDHC (Class 6) cards back in May 2008 where they were primarily used for storage for my HD Canon camcorder.  This past summer, the first started to give me internal errors to the point that I've lost majority of the 16GB and now have some 200MB left on the card that is accessible.  The 2nd card failed on me today.  I've turned on my Nikon D80 DSLR and found that the memory card was "locked", so as I pulled it out I found that A) the lock tab was missing and that B) the front of the plastic housing was ripped off.  Somehow the plastic didn't hold up to the bi-weekly insertion and removal from my Nikon to the memory card reader.

So, could I recommend these cards?  Not really, if you want them to last for more than 2-years.  Sadly, I have memory cards dating back to the 128MB era and they are just fine.  I guess they don't build them as they used to.

Now I have to find 2 replacement 16GB, which fortunately won't cost me the $75 each that I paid a little over two years ago.

With the prevailing trends towards much higher external storage (for extra photos, movies, songs, etc), many SD cards manufacturers are introducing the 256 GB microSD cards, thereby, temporarily lowers the lower capacity cards. I got this one for under $40, whereas the newer and larger 256GB equivalent are being priced at nearly $200.

It's made by Samsung, despite the Note 7 overheating fiasco, as a longtime Samsung user, I know this is a one time blunder & does not affect their other products.

Yup.  That's about it. - it'll happily fit into my multicard reader, but who needs it for that?  Just wanted to find a more economic way of shooting long form video.

I think it was a bit misconcieving, I mean who sales mb Sandisk anyway? Everything is GB now.  So I got a disk I can't use in my camera and the return costs over half what I paid.

It works as it should but it is a complete ripoff. I got a 32 gb card for my phone and it was less than 1/9th  the price these things cost.

When I first got PS2 a year ago, I didn't had any memory with it and a lot of good games now need it to store a save point, so I really couldn't progress much on those games (gta3). There's not much to write for thr review other than few facts
- This is not compatible with PS-One
- It's much faster in access (saving and loading games) than PS-One : about 200 times.
- Absolute requirement.
- Last but not the least, it's a little expensive for the price and I'm sure that pretty soon other companies would be coming up with higher memory modules, just like it happenend for digital cameras.
I would recommend a different memory card than Sony, which is from NYKO and available in most game shops. This card is exactly same as sony, has the "official licensed product" from Sony Playstation. It was originally used by Sony with their game consoles and then Sony started making their own.
If you buy it in a game shop, it's couple of bucks cheaper than the Sony brand and it comes in YELLOW color.

Basically Need it for your Vita if you plan to do ANY sort of DL Games. I've found on Amazon it's usually cheaper to grab two 16's vs a single 32 but if you don't want to keep switching memory cards 32 would be your best bet. As we know, price for these are atrocious and you should only bother buying if they are on sale...I got mine for 25 when I upgraded from 8GB to 16GB but looking back probably should  have grabbed another one. Don't think I personally could pull the trigger if it's $30 for a 16GB so wait for a sale of some sorts if you can.

5/5 for being a good memory card to store games/saves/etc
1/5 for its awful price.

3/5 overall

THIS IS NOT A THIRD PARTY CARD!!! It is a Sony licensed product, and a Magicgate licensed product! It works just as well as the "official" memory cards, because these were at one time going to be the official memory cards!!
If you don't own one, don't write a review!
I have owned 4 of these memory cards in the past 7 years, and I still have all of them and they each work perfectly. I haven't had one single corrupt file on these cards, I can't say that about the "official" cards though.

If you are looking for a memory card, get this one. It works perfectly, and is cheaper in price.

I bought this memory card to avoid paying the outrageous prices that Blackvue charges for their memory cards for dashcams. A 64GB memory card through them directly would have cost me close to $60. A note for Blackvue dashcam owners: you won't be able to plug and play with this memory card, the dashcam will keep giving you a check memory card message. I did some research and found out that you have to download the Viewer software on your computer and then press the format memory card icon to be able to format your memory card to MS-DOS Fat which is not what this memory card is formatted as out of the box. I think it's set to Fat32.
