It has a 5-year warranty or 1,200TBW (Terabytes Written). This has matured into a very useful product. I first used it a year or so ago, and the software was very limited – about three features. Data Security (offers several encryption password options).Sets a Data Security cache size for longer life.Over-provisioning to reserve extra free space.Invoked Rapid mode (intelligent DRAM caching of data, for read acceleration and write optimisation).Terabytes written (guarantee uses this).Analyses the drive condition and temperature.Most NVMe SSD come with software to help manage the device. There is a slightly faster 970 Pro version that uses 2-bit, TLC, 64-layer VNAND and copies files faster again. For example, the HP almost keeps up when the bus is used to copy more, smaller files. In practice, the different file sizes make a huge difference. It is over two times fast at read and nearly ten times faster at write than the NVMe M.2 SSD in my HP EliteBook 1030 G2 (below and I thought that was good). In fact, that is around seven times faster than a spinning disk. I had heard it was fast – rated at 3,500MB/s read and 2,500MB/s write. Typical users will be gamers, those who transfer large files, video/still editors who drink too much coffee waiting for renders or data to copy to backup devices. Part of the secret sauce is its Phoenix controller and Intelligent TurboWrite technology enhance high-end gaming and 4K & 3D graphic editing. Be prepared to weep over your current speeds. If you are in doubt download Crystal Disk Info and Crystal Disk Mark to verify what type of SSD (or HDD) you currently have. Most high-end computing devices use NVMe. ![]() ![]() Who uses it?Īnyone with an NVMe M.2 SSD slot on their motherboard or in the laptop/tablet. In practice PCIe 3.0 is bidirectional – you can have 4,000MB/s going both ways, e.g. Typically, modern NVME SSD is PCIe 3.0 x 4 lanes giving a 32Gb/s transfer or a staggering 4,000MB/s. You can recognise NVMe SSD by the single slot in the gold finger connector (SATA 600 has two). ![]() PCIe is several times faster than a standard SATA 600 bus. In other words, they must wait until a read is done to perform a write (command queuing). In practice, data transfer rates on SATA are well under half the theoretical speed because they are unidirectional. (MB is Megabyte, Gb is Gigabit – for conversion see the website here. SATA stands for Serial ATA and depending on the hard disk age may theoretically be Larger files read/write faster smaller more numerous files copy slower. Raw speed excludes the speed loss due to the bus interface and things like sequential or random read/write and file size. Raw read/write speed is not in itself an indicator of performance. It uses Samsung’s latest generation of 64-layer, VNAND, Non-Volatile Memory, its own Phoenix controller, and a PCI Express (PCIe) bus to transfer data. The Samsung 970 EVO NVMe (website here) is a solid-state disk (SSD) storage device in an M.2 2280 (22 wide x 80 mm long) format card. The Samsung 970 EVO NVMe SSD is so fast that a full Windows 10 Pro install including massive updates, 20+ drivers and 20GB of software took about an hour.
