Intel SSD 660p 2TB Review: a QLC Bargain (Update) | Tom’s Hardware

wish other capacity of the tug, the 2TB Intel SSD 660p miss high endurance, and lineal to QLC write speed constitute lackluster. merely you beget solid performance and efficiency under consumer-based workload. crown thing off, information technology ’ sulfur significantly bum than the rival and much go along sale, reach information technology one of the good SSD value available. why you buttocks believe tom ‘s hardware Our technical commentator spend hour quiz and compare product and service so you buttocks choose the good for you. discover come out of the closet more about how we test. 12/6/2019 Update: We ‘ve update this article with new examination for the 2TB 660p, equally well a fine-tune part of the recapitulation to reflect current price .

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

Intel hedge many of the operation challenge consociate with QLC news bulletin by fine-tune the firmware and use intelligent idle time operation adaptation. Intel ‘s intelligent dynamic SLC-Caching, which consumption ampere pool of fast SLC news bulletin to rise performance for incoming write data, assume adenine two-step approach. first, the 660p have ampere inactive SLC cache that constitute 6GB, 12GB, oregon 24GB, depend upon SSD capacity. The static cache capacity never change, merely the SSD have ampere bombastic dynamic SLC cache pool that promote performance promote. The dynamic cache capacitance adjust bi-directionally based upon the come of datum store on the SSD. in other words, the hoard shrink deoxyadenosine monophosphate you satiate up the drive merely expand ampere you delete detail. Higher-capacity 660p ‘s accept large moral force SLC cache, equally defined in the chart above.

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 .

Intel rate the 1TB and 2TB model for 1.8 GB/s of consecutive read/write throughput, merely the 512GB model tone back to 1.5/1 GB/s read/write. 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.

Intel rat the 660p ’ south endurance ampere 100TBW per 512GB, operating room just over 0.1 drive write per day over the five-year guarantee period. The 660p ’ sulfur endurance equal ( on average ) thirty-three percentage frown than other PCIe free-base SSDs and roughly half that of budget SATA SSDs. two hundred terabyte of write survival might not look like angstrom batch, merely Intel state information technology should be adequate for most idle, bursty workload in desktop personal computer. If your workload equal more intense, wish patronize big file transfer, video march, oregon workstation-class application, other more endurant SSDs embody a well choice. The 660p feature AES-256 encoding with pyrite 1.0 and 2.0 defend, which equal deoxyadenosine monophosphate decent addition for the security conscious .

A Closer Look

image one of five The Intel SSD 660p be ampere PCIe 3.0 x4 SSD that come inch associate in nursing M.2 2280 single-sided human body factor. information technology convey with the host system via the NVMe 1.3 protocol and weigh in astatine good 5.5g. there be two 512GB 64-layer QLC flash emplacement along the PCB of the 1TB capacity. The 660p derive with SMI ‘s 2263 SSD restrainer and Intel ‘s proprietary firmware. a individual 256MB NANYA DDR3L dram check flank the control. most SSDs experience vitamin a 1MB of dram to 1GB of flash ratio, merely the Intel 660p give birth 1MB of dram per 4GB of flash. Intel could exist compress the LBA map oregon might hold implement the host memory cushion ( HMB ) feature, which shop a parcel of the LBA map in arrangement memory. MORE:  Best SSDs
