This M.2 SSD controller card lets you install two M.2 SATA solid-state drives (SSD) into your PC through PCI Express. You can mount virtually any M.2 drive directly to the card, giving you a convenient and discreet way to improve your computer system performance. This M.2 controller card lets you take full advantage of the performance and size benefits of NGFF (Next Generation Form Factor) SSDs. M.2 drives are smaller than typical platter drives or mSATA-based SSDs, so you can install them in tighter areas within your computer case. By freeing up space within your computer, you'll also have more room for additional hardware upgrades. When you couple the card with an M.2 drive, you can give your computer's performance a noticeable speed boost, enabling you to replace your platter drive with a faster M.2 SATA III (6Gbps) solid-state drive. By installing your operating system on the M.2 drive, you'll have faster access to the files you commonly use, and you can continue to use your higher-capacity platter HDD for bulk storage. You can rest assured that your M.2 SATA drives are compatible with the card. It supports the most common drive sizes, including 22110, 2280, 2260, 2242 and 2230. The M.2 controller provides additional installation flexibility with a dual-profile design that fits standard or low-profile cases, so it's the perfect solution for small form-factor or full-sized computers. This M.2 SSD controller card is easy to install, with native OS support and no additional drivers or software required. The PEX2M2 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
