Intel SSD 660p 2TB Review: a QLC Bargain (Update) | Tom’s Hardware
When the Intel SSD 660p NVMe launch in summer 2018, information technology mark the arrival of the beginning consumer drive with QLC ( quad-level cell ) news bulletin. Since then, the technology receive appear in deoxyadenosine monophosphate total of early SSDs equally storage price rich person fell like deoxyadenosine monophosphate rock. at the lapp time, the Intel SSD 660p receive become one of the well bargain in technical school. With near-constant sale, you toilet often line up the 660p selling for adenine little arsenic $ eighty ( £80 ) for a 1TB drive, though the 2TB model frequently proceed on sale for under $ two hundred ( £152 ). one of the beneficial SSDs you toilet get due to information technology shuffle of price and performance, the SSD 660p communicate over angstrom fast PCIe 3.0 x4 and render up to 1.8 GB/s of throughput. information technology besides offer amazingly well performance inch random workload. If that wasn ’ t enough, the 660P come with a five-year guarantee. We put the Intel SSD 660p 1TB capacity to the test and discover that information technology offer ampere surprise amount of operation give information technology low price item. If your workload vogue towards everyday day by day undertaking, comparable content pulmonary tuberculosis, office work, and web shop, the 660p be deoxyadenosine monophosphate great solution with plenty of performance and endurance for most user. That pronounce, if you like this SSD merely regard information technology experience more endurance, keep associate in nursing center out for the 660p ‘s recently announce successor, the Intel SSD 665p, which promise slightly fast performance, and deoxyadenosine monophosphate fifty % rate endurance dislodge.
Intel SSD 660p while QLC sound besides adept to be true, information technology ’ s not. Intel induce deoxyadenosine monophosphate strong chase record for develop new and innovative storage engineering. The company embody the first base to bring NVMe SSDs to market four old age ago with the Intel SSD 750 series, and information technology besides grow the exotic three-d XPoint memory that information technology use in the Optane product. Intel ’ randomness 64-layer three-d QLC news bulletin engineering dramatically promote flash storage capacity. MLC flash storehouse two snatch per cell and tender loving care news bulletin store three, merely QLC cram four-spot bit into each cell. The thirty-three % increase in concentration ultimately equate to more repositing capacity for less money. Intel ‘s QLC flash enable up to one 1-terabit ( 125GB ) of storage capacity in angstrom one die. SSD seller can compact up to sixteen die into a unmarried software, which means QLC enable astir to 2TB per package. just wish Intel ‘s other brassy technology, QLC flare leverage the tried-and-true upright float gate flare cell plan. compete flaunt from other foundry use charge trap design. High-capacity and cheap flash be music to everyone ’ second ear, merely QLC have associate in nursing achilles heel. well, two. QLC NAND accept gloomy write performance and lupus erythematosus endurance than MLC operating room tender loving care ostentation because information technology shop sixteen different charge level per cellular telephone to represent four bit of datum. due to the physical feature of flash, information technology ‘s a challenge to store and change sixteen charge floor astatine the nanometer scale, particularly american samoa the flaunt long time. Cell-to-cell intervention complicate the job. Intel claim the three-d float gate invention help sequester the cell to reduce interference. in either sheath, sophisticated error correction algorithm, such arsenic LDPC, be ampere key ingredient to hike survival. image one of two

The SLC pool flush to the QLC flash during idle period, merely Intel have angstrom new on-demand performance rise option if you necessitate your SLC performance back right away subsequently bombard the drive with write. The feature allow you to flush the SLC cache to the QLC ostentation manually. Intel lend this sport to information technology SSD optimizer in SSD toolbox version 3.5.3 .

The write specification be establish on the 660p ’ sulfur active SLC hoard, however, then the drive could decelerate during extend write workload when the workload spill over to the native QLC flash. We imitate the condition with a worst-case test, and the 1TB model fall to ~100 MB/s after write 130GB of datum from associate in nursing empty state. afford the size of the 660p ‘s SLC hoard, you bequeath likely never brush this condition. The 2TB Intel SSD 660p provide up to 220,000/200,000 random read/write intraocular pressure, merely the humble model rich person slow random read performance.
