ACP-EP 4GB 150X Extreme Performance Secure Digital Card (SD) - EPSD/4GB-150X

I have been using the card with a Nikon camera on occassion. Bought it 3/29/07 and now it won't even let me access it. The camera said "memory error" and the computer won't read it. The customer support is so hard to get in touch with. No point on have 5 year warranty if you don't intend to honor it.

This SD memory is very much faster than it's standard counterparts. I have been pleased with the performance. It also works well as a flash drive for backing up critical files on your PC.

Bought two of these SD cards for 2 different cameras--one of my cameras was not compatible with this card, but there is no list of camera compatibility prior to purchasing. I was unable to return this card for a full refund with Buy.com--i had to go directly thru the manufacturer & even then it was only for an exchange for a single 2GB card (not two 2GB cards!). It does work with my canon powershot, BUT I will occas get "error/data corrupted" messages after shooting a picture, which renders that photo unusuable. Would not recommend this product.

I received the SD card fast. It was in perfect condition. I have been using it in my camera and I love it! Buy.com has very good prices and wonderful products.

Installed on a Treo 700wx - works fabulous. Pulls up iSilo docs lightning fast. Have several wmv movies 250-350mb - fast with these as well. These studder very slightly at times, but this could be the device too. Overall VERY pleased. Did not have to format the card or anything. Just copied all my content from my previous smaller card onto the this new card via a desktop, then up and running!

Extreme Performance/150x does NOT support Vista Readyboost.

Failed on readyboost test. Unable to return the product to buy.com. Need to contact the manufactory. From the event log: The device (Unknown Unknown) will not be used for a ReadyBoost cache because it has insufficient write performance: 906 KB/sec. Tested again.... The device (Unknown Unknown) will not be used for a ReadyBoost cache because it has insufficient write performance: 943 KB/sec. Sad... :(

I recently purchased two EPSD/4GB-150x cards for use in two laptop computers with built-in SD slots so that I could take advantage of Vistas ReadyBoost feature. I thought that the cards high read/write speeds would be sufficient to support ReadyBoost. However, I was wrong. Despite the great specs of the cards, they will not support ReadyBoost. This product is not returnable to Buy.com (this fact was clearly noted when I placed the order). I contacted the manufacturer and the representative confirmed that the cards are not ReadyBoost compatible. But, since the cards are not "defective," there is nothing they can do. So, I'm stuck with two 4G cards for which I have no use.

When I received the ACP 4GB Card the first thing I did was format it for my Canon a710IS camera. I had no problem. In fact the card is classified as a 4GB card. It actually has 3.86 GB. The Dane-Elec and Sandisk 4GB cards I own only have 3.7 GB. I had no problem with the ACP card at all. It worked flawlessly. I would not hesitate to buy another one if the price is right.

Had it for a few weeks. So far no hiccups. The only 4 GB standard SD card I could find for my older digital camera. Would recommend to others.

Only used for a few weeks, but the quality and performance are good so far. My last SD card (of another manufacturer)broke at the metal contacts after a 2 years of use. This 150X card is faster than the SDHC cards that are now the standard for larger capacities. I got this so I could take longer videos on my digital camera.

I bought the card for my Palm Treo 700wx as it will not take SDHC cards and this was supposedly not a high capacity card. It did not work in my Treo but works great for my camera and laptop. I have no complaints just beware that it may not work in all devices.

Although I don't have any other SD cards, I do own a number of other cards including XD, compact flash, sony stick, etc... This card is easily the fastest card I own. I purchased it for my Tomtom 720 GPS to hold music, photos, and audio books. The fast access makes browsing for and playing media much faster than can be expected from "regular" speed cards. Also the time it takes to put large quantities of files onto the card from my laptop is unbelievably fast. Nearly half a gig in less than 5 min! Shipping was fast and free. I really feel I got more than I paid for!

This card is a great value for a 4GB card. It works fine on the PC. The problem I had was that there is no way this is a 150X Speed Card as advertised. I got this card to give a big jump to Vista using readyboost. No go. System says card doesn't meet minimum reqirements. I have a 1 GB card that is 4 years old and much slower than 150X and it works fine with R/B. So... Good if you want a cheap card with good storage. Bad if you want to speed-up with ReadyBoost. I gave this product such a low rating because the only reason I got it for (readyboost) does not support the low speed of the card.

A high speed (150x) 4GB SD CARD that will work with legacy products that can't handle HDMC SD Cards. Fast, reliable, and low cost. Wish they had an 8GB SD CARD, but haven't seen any on the market yet.

This replaces a Transcend 4GB SD card that failed after about a year. Worked perfectly the first time. There aren't too many 4GB SD choices since most are SDHC at that capacity, and some have compatibility issues. This appears to be a winner as well as a bargain.

I ordered the memory upgrade and it has performed just as I expected. No hitches or glitches. As far as speed is concerned, I have no way to tell if it is performing up to the advertised speed, but as long as the perforance is great....

Great little storage card for a digital camera. No need to pack a computer anymore for downloading on trips.

great little card for the price. Buy.com delivered very fast and the card can be used like all other SD cards. It does performs faster than normal SD cards.

I used the 4gb sd card to load maps/driving directions for the entire USA for use in my Garmin IqueM5. I had tried other sd cards prior and they just didn't work properly or were too slow. I bought a 2gb SanDisk Ultra which worked great but wouldn't hold all the maps. I decided to try this 4gb and so far it works just as well and holds all the maps and the price was great.

I got this card for my camera (SD300) because I often use it to take videos. Because video burns through memory so quickly I wanted a big card so I don't miss a moment (changing cards or running out of space at the wrong time). This card works great. I tried a slower card which couldn't keep up, but this one has had no problems. And the price was very good. I'll get another when they are back in stock.

This card provides plenty of affordable space for all those pictures and movies that your camera can take. Many of your digital cameras have the ability to make movies but those movies can take up a lot of limited storage space. Now you can make those movies without sacrificing your photo shoots.

I received it and I immediately put it on trial. First disappointment: the speed was no more than 200 kBps. I was about to send it back, but I gave it another chance. Since then a few weeks passed and the average speed is 4 MBps. Curiously, from an ftp-server speed is 6-8 MBps. Can anybody explain me why? The card works flawlessly with my Palm T|X and the price is very good. I highly recommend this SD Card. Just take care that your device can read all the 4 GB of it.

I bought this in conjunction with Casio EX-S600SR digital camera. Everything works great together. Slapped in the card, camera recognizes it, transferred a few files back and forth to the card to make sure everything worked good, and it does. Much faster than any of the compact flash cards I've used for my previous cameras.

First SD card was dead on arrival. Re-ordered and second card is working great. Can not beat the price. Also Buy.com was great with the return on the original card.
