Question 1

This is a DRAM-less drive, meaning that it will use some of your system memory for cache..  is this true?

Accepted Answer

Not true. Cache memory is totally separate from Dynamic ram(DRAM) and this drive is a Static Ram drive(SRAM). Drives, even if made from memory chips, are still made for drive space and not for cache or shared memory. Some programs may describe the use of computer resources and emulate the function of another device, but that is not what this device is designed to do.

Question 2

Will this work with my Inspiron 15 Gaming 7567 laptop?

Accepted Answer

It should work, it may require require you to update the bios though

Question 3

Can anyone tell me if this will work with either the ASRock 970A-G/3.1 or the ASUS USA - 970 PRO GAMING/AURA. I want to use it as my Primary Boot Drive?

Accepted Answer

Hi Bonnie,

If both motherboards have an M.2 drive slot, it will work, but there is something you need to know about these M.2 drives.

The M.2 drive is VERY difficult to install as a BOOT DRIVE. It will install into the slot easily enough, and get itself recognized by the BIOS, but it is not an ideal boot drive. It is better used as an auxiliary drive. It is wicked fast for sure, but, there are  several extra steps to turn it into a boot drive. I am sorry I don't know what those steps are yet.

Secondly, Windows 7 and 10 require a driver download to get the drive to work and be recognized by the OS. Simply GOOGLE "M.2 Driver for Windows 7, 8.0, 8.1, or 10. You will see a link to a Microsoft download sight where you can download and install the driver.

Thirdly, this M.2 drive is ideal for many applications and especially for games, but it should not really be used for a boot drive.

Finally, the M.2 drive comes in two flavors and they are very different. The NVMe - PCIe version has only  one tab. The SATA version has two. The PCIe is the high speed read-write version, the SATA version is no faster than any other 6.0 SATA drive.

These drives are not real great for everyday use if you are just  trying to hurry your read-write capacity along. Sorry to have to tell you that, but I learned the hard way

I wish I knew this information before I bought my HP EX900 M.2 PCIe 500GB drive. I probably would not have purchased it because it is a lousy  boot medium. But now that I have accepted that, I love the drive for its speed and I wish I got the 1 Terabyte size instead.

Good luck with the new drive, and let me know if you find an easy way to get it to boot.

Sincerely,
Tracy A Gordon
