Predator m.2 diskmark5/22/2023 This most likely matches the speed of SK hynix’s 128-Layer TLC, which is 1,200 MTps.I needed to reinstall Win10 on my spare laptop that I’d stolen the SSD out of and had a 10 year old hard disk sitting around. The new flash operates down to 45/450 microseconds (820/82 MBps) read/write, respectively.Īlthough the company didn’t specify the exact speed that the flash interfaces with the controller at, Samsung specified the flash operates at Toggle DDR 4.0 speeds, which ranges from 800 MTps up to 1,400 MTps, at a 1.2V supply voltage. This, in conjunction with some other modifications like an enhanced bit line precharge scheme, couple-capacitance-minimizing technique, progressive Vth window scheme, and random pre-pulse sensing scheme, enables Samsung’s V6 V-NAND TLC to respond 10% faster to both read and program requests over the last generation of flash. The current design splits each of the two 16kB plane cell arrays into two 8kB sub-planes with even/odd sensing for even faster performance capability with the limited space budget. Samsung's next-generation V7 V-NAND will most likely implement both multi-stack and Cell Over Periphery (COP) concepts for improvement. ![]() ![]() Lacking this design component, Samsung’s V6 V-NAND suffers in regards to bit density. The 250GB and 500GB models come with 512MB of DRAM while the 1TB and 2TB receive 1GB and 2GB, respectively.īy placing the additional periphery, page buffer, and other select circuitry under the cell array rather than its border, companies can increase bit density per wafer. These DRAM ICs interface at up to 1866 MHz and need as little as 1.1V to operate. The 980 Pro leverages DRAM for caching its FTL metadata, and for this task, the company outfitted the SSD with LPDDR4. The company states that the new PCIe 4.0 x4 NVMe 1.3c controller can natively process up to 128 concurrent I/O queues, which is up from 32 queues on the previous PCIe 3.0 controller, leading to a more responsive latency profile. Samsung did mention some other interesting points on the controller’s IO processing capability, however. Samsung also doesn’t specify the channel count, although it’s probably an eight-channel design. While the previous-gen Phoenix leveraged five Arm Cortex R5 cores, Samsung hasn’t specified what type of cores, or how many, power this new controller. The new SSD controller, dubbed Elpis, measures 16.5 x 16.5mm and features a DRAM-based multi-core Arm architecture built on Samsung’s 8nm manufacturing process node. It supports secure erase via the Format NVM command and crypto erase capability, as well as S.M.A.R.T. According to Samsung’s statistics on over 661,000 NVMe SSDs, the company says 99% of users write up to 156 TB of data within five years, and 99.7% write less than 600 TB.įurthermore, unlike most SSDs on the market, Samsung’s 980 Pro supports AES 256-bit hardware-accelerated encryption that is TCG Opal V2.0 and IEEE1667-compliant for protection of data at rest. This change is a calculated move by Samsung, though. ![]() This is a bit of disappointment, not only for us, but also for the potential buyers who have already expressed some grief on forums. Total Bytes Written and Warranty Ratings ProductĮven with the new TurboWrite 2.0 implementation, Low-Density Parity-Check (LDPC) ECC, and 9% over-provisioning, Samsung still pulled back on the 980 Pro’s endurance ratings due to the TLC flash, matching the 970 EVO Plus within the same five-year warranty period. These performance figures aren’t consistent across the capacity of the device like they were on the 970 Pro, however, so the larger drives are faster than their slower counterparts. The company rates the 980 Pro to hit peak sequential speeds of up to 7/5 GBps read/write and upwards of 1 million random read/write IOPS. Prices range from $90 for the 250GB capacity up to $230 for the 1TB model, with the latter having the best price-per-GB. As expected of Samsung’s flagship SSD, each capacity commands a premium over competing drives. Unfortunately, Samsung will not release the 2TB model until late 2020. Samsung’s 980 Pro is available in capacities spanning from 250GB up to 1TB, but unlike the last-gen 970 Pro, the 980 Pro will bring back the 2TB capacity point.
