Samsung 850 Pro 1TB SSD... iMac 5 yr old Seagate internal HD 1TB failed... backup from apple's Time Machine allowed Mac OS X to be restored to a 1TB external HD. With that solved for the moment... I could take the time to research my replacement... SSD's kept coming up as a viable replacement over the standard HD. Speed, dead quite, during my search, ADT had the best competitive pricing. That difference in price from other venders, enabled me to step up from the Samsung 850 1TB... to Samsung 850 Pro 1 TB 2.5-Inch SATA III Internal SSD (MZ-7KE1T0BW)... Other parts were also needed to complete the installation, ie: 3.5" to 2.5" Adapter bracket w/ heat sink (heat sink overkill, not needed with the cool running SSD) and cables... I chose to order installation kits for the Samsung SSD from another vendor. Complete kits designed for the Apple iMac 21" (mid 2010). (important because internal iMac designs varied year to year) ... SSD arrived within 4 days. Install took a few hours. OSX startup in fast, almost seems instant. About the same speed this Mac use to awake from "sleep" mode. (blink) This was my first dealings with ATD... price, speedy delivery, setting up accountsa, fund transactions were smooth and drama free. 5 out of 5 stars. Keep it up guys/gals... Thank you for allowing me to share my experience. -- R

Unbelievable! I have never had such a great experience with a company! They even called to double check everything so there were no mistakes. The woman was very polite and professional. I received the part within the estimated time period and there were no shipping defects!

Good selection and good prices I found ATD to have very competitive prices, a vast array of products to choose from, and their site was easy to navigate. I'll definite consider ordering from them again.

Still the cheapest price after almost 2 month after purchase I ordered a Samsung EVO 850 1TB SSD from them about 2 months ago, it's still the best price in the environment of quickly dropping price of SSD. Shipping quickly, but arrived a little slower than desired, but overall good. Very happy with the purchase and the company.

Excellent Service, Price, and Oversight I ordered a SSD for my daughter from ATD mostly because of their low price. I had my VPN attached when I placed the order. Within minutes I received a call from ADC asking about the discrepancy between the location of the IP address and the card used in the purchase. I was impressed that they had the systems in place to recognize such an anomaly and their diligent follow-up. The order arrived quickly and well packed. My overall impression is that they are a well run and professional company.
