XP941 512GB M.2 PCI-e Gen2 SSD NAND based Solid State Drive (MZHPU512HCGL-00000)

Slim Package, Big Performance: The new Samsung XP941 M.2 PCIe SSD delivers a level of performance that easily surpasses the speed limit of a SATA 6Gb/s interface. With sequential data reads as high as an incredible 1,170MB/s (megabytes per second) on the 512GB model, the XP941 provides the highest possible performance available with a PCIe 2.0 interface.

The new standard
The Samsung XP941 SSD in the new M.2 form factor is set to supersede the older mSATA format. Weighing in at just 8g, it's 1/5th the weight of a standard 2.5-inch SSD and takes up just 1/7th of the space.

Ultra green
Consuming just 80 mW of power when idle, and 5.8 W when fully active, the Samsung XP941 delivers longer battery life without sacrificing performance.

For desktops and laptops
The new M.2 SSD format (previously known as NGFF - New Generation Form Factor) is compatible with the latest generation netbooks and notebooks containing a PCIe M.2 socket, such as the new Sony Vaio Pro.

If you intend to purchase this product as an upgrade for an existing smaller drive, you should check if the existing drive is a Samsung XP941 or other M.2 PCIe SSD.

This is 'old' tech now, and is 'limited' by the PCI-E 2.0 interface (and I'm sure my MSI Gaming 3 M2 slot or the idiot who installed it-me) but the performance is still nothing short of breathtaking.

You can get cheaper SATA 6Gb/s drives of similar, or even slightly greater capacity for about the same money but the combination of speed and capacity this drive offers is unmatched (at least here and now).

Fast and large enough for a great many users it's not without a few faults, though.
This is an OEM part so no nice box, (it comes in a natty bubble wrap bag), no bundled software and no accessories to ease software/system migration.
This type of drive can have issues if you want to use it as a boot drive, something I picked up in the reviews I read, but they're all dated 2014. My install went without a hitch, but updating your motherboard BIOS prior to installation and making sure AHCI mode is enabled should help compatibility issues.

Blazingly fast and (fairly) cheap for a 512Gb part it's a great upgrade to an ailing mechanical HDD or for someone who just wants everything NOW.
Just bear in mind the lack of software bundle and possible compatibility issues. But then again, you all know about the revised Distance Selling Regulations, don't you? ;)

Fast as

I have one of these on my rampage V and use it as my boot drive it is so much quicker that my 840 pro.

The setup was easy a couple of bios changes and boot from a usb stick to get the os on, took mins :)
