ChipsNAND The new generation continues its gradual and measured entry into the market as the successor to the TLC - this time even in the most agile models that exploit the interface of the TLC -PCI-Express × 3.0 4
Despite pessimistic forecasts made for them at the beginning, NAND chips in TLC configuration that allows saving three bits of information in each storage cell have proven themselves and have become the new default of the E-SSD In almost all categories and areas with reliability and performance that exceeded expectations sometimes, especially availability levels and costs that allowed us to get used to the current situation where you can pay much less than one weight for gigabytes of agile volume. All of this has not happened in a single moment, but gradually - and now we are in the era of the first steps of the technology -QLC Which one day should make storage drives even larger and more accessible.
Intel and Samsung were the first to introduce NAND chips to the world, which store four bits of information per cell, to a higher density of 33 than TLC chips in a similar structure, and now Micron is recruiting its Crucial brand and introducing the P1 Of 660p models from Intel Which offers M.2 configuration and standard support NVMe Competitive price.
God-Crucial P1 will be based on a new silicon-powered SM2263EN controller, plus the 3-D QLC chip of IMFT (the joint manufacturer of Intel and Micron) with a volume of 1024 gigabit per layer, in total volumes of 500 GB, one terabyte And two terabytes - when the basic model needs a chipset NAND Alone to reach the required volume, while the terabyte model is satisfied with two boxes chip To do this.
The drive ensures continuous transfer speeds of up to 2,000 megabytes per second in reading and up to 1,750 megabytes in writing,SSD Chosen, and Performence Randomize up to 250,000IOPS in writing and reading small 4 files in kilobytes (in the 2 terabyte model available for later purchase).
Official 110 prices for 500GB and 220 for double the volume may sound promising on paper (the 2 Terabyte will come late and not yet priced) compared to other NVM drives, but here's where we recall that the 660p of Intel Based on the same beef and chips QLC Were presented two months ago with prices of 100 dollars and 200 dollars for the corresponding volumes, so there is certainly room for improvement. In addition, a five-year warranty, but with minimal writing support of about a tenth of the total drive volume every day, reminds us of the essential technological limitations with which the HP-QLC At this early stage of their lives.
We certainly welcome the introduction of new QLC models for the race, especially in the world of NVMe, which is rapidly becoming the next hot topic - but at the same time,Crucial The practical P1 dropped below the recommended threshold as quickly as possible, and availability would be broader and preferable to that of Intel drives. Better availability ofQLC The first can bring us closer to the moment when they will be better than any model with TLC chips in terms of cost-benefit - and then only the sky is the limit.
