Product Description
Samsung PM981 MZVLB1T0HALR-00000 Interface: PCI Express Gen3 x4 Form Factor: M.2 NVMe 1.2 Flash Memory Type: Samsung 64-Layer TLC 3D V-NAND Controller: Samsung Polaris V2 Sequential Read: Up to 3200 MB/s Sequential Write: Up to 2400 MB/s Random Read: Up to 380K IOPS Random Write: Up to 440K IOPS Special Features: AES-XTS 256-bit Hardware-based Encryption Engine TCG/Opal V2.0 UBER: <1 sector per 10^15 bits read Max. Non-operating Shock1500G (0.5ms duration with 1/2 sine wave)Supply Voltage / Tolerance: +3.3V ± 5% Physical dimension Width: 22.00 ± 0.15 mm Length: 80.00 ± 0.15 mm Weight: Up to 8 g Power Saving Modes: Supporting APST, Supporting L1.2 Mode Support Admin & NVM Command Set RoHS Compliant PM981 delivers optimal SSD features for PCs. By supporting the PCIe interface standard up to 4 lanes and TurboWrite technology, faster Seq. R/W speeds are accomplished, delivering higher performance while using less power via an NVMe power-saving mode. Featured in an M.2 form factor, PM981 uses 88% less space than 2.5” SSD. The PM981 is fully consist of semiconductor device and using NAND Flash Memory which has a high reliability and a high technology in a small form factor for using a SSD and supporting Peripheral Component Interconnect Express (PCIe) 3.0 interface standard up to 4 lanes shows much faster performance than previous SATA SSDs. The PM981 provides 256GB, 512GB, 1TB and 2TB capacities. It’s sequential performance is up to 3,200MB/s for read operation and 2,400MB/s for write operation by 4 lanes. It’s random performance is up to 380k IOPS for read and 440k IOPS for write operation by 4 lanes. It could also provide rugged features with an extreme environment with a high MTBF.

Customer Reviews
This is an OEM drive. It appears to be the next version of the 970 EVO, and is OEM supported (does not have Samsung support). It is an excellent drive and has the Phoenix controller, not Polaris. I used this part # because it is the 1 TB version of the 512 GB drive that came in my Lenovo Ideapad 720S – meaning the existing drivers would work.I backed up the 512 GB disk1 and restored to this 1TB drive (4 partitions - one was a FAT32/BIOS-UEFI partition). This turned out to be more difficult than I imagined, due to several factors: Windows 10, Acronis Disk Director 12, and a 4K Very High resolution 15" laptop screen. Outside of the Windows 10 environment, getting cues to display correctly on the very high resolution monitor was impossible. Also, getting the settings correct using Acronis True Image 2019 were challenging because the drive is formatted GPT, not MBR, and uses the Intel Rapid Storage Technology environment in RAID mode to support Optane. Once the initial load was complete, I had issues that made me suspect that Windows 10 was not configured correctly. Attempted to use Acronis Disk Director 12 to clear and reformat the drive (booting from a USB WinPE drive that included the partition software), but it was unable to change anything – couldn’t get to the boot agent to restart and apply changes. Found an AOMEI Partition Manager that could clear the drive without rebooting and was able to start over. But. The USB was running just the basic AOMEI Partition Manager and, not having a Windows display manager running caused the cue text to appear in a size 4 font, which was readable if you were very young or very nearsighted. Many pop-up windows could not be resized enough to see the text in them! I eventually cleared the drive, got it into GPT mode, and restored my 4th set of backup images. I would give this a 1 star but that would be totally unfair because the drive itself was not the problem.
