Many moons in the past, famed enterprise capitalist Marc Andreessen described the time period “product-market match” as “being in an excellent market with a product that may fulfill that market.” To show that you’ve product-market match, simply promote a significant quantity of your product and repair to finish clients – no subsidies, no free trials counted as revenues, no grants, and no associated occasion revenues. Every time an thrilling new expertise guarantees the moon, we at all times wish to see product-market match earlier than investing. We don’t put money into tales, we put money into traction. That’s why when Twist Biosciences (TWST) guarantees their buyers that DNA information storage is across the nook, we needed to take a more in-depth take a look at the thesis.
DNA Knowledge Storage Defined
All information is made up of 1s and 0s. All DNA is made up of As, Ts, Cs, and Gs. Put that approach, it might make sense that if the 1s and 0s could be transformed to ATCGs, then information might be saved on strands of DNA. So, is it doable? Sure. Nevertheless, it’s not precisely that straightforward.
To retailer information on DNA, the specified info first must be mapped onto the 4 nucleotides (the As, Ts, Cs, and Gs) of DNA. That is performed utilizing a DNA synthesizer. Whereas this synthesizer won’t assist Paul McCartney create a pop Christmas hit, it’s totally very important to the info conversion course of. Its main objective is to affix nucleotides in a selected order to construct DNA molecules. In brief, it creates a “synthesized” strand of DNA. The nucleotides are chemically modified to permit them to suit snugly and simply onto the DNA chain. As soon as that is full, the DNA could be “purified” (separated from different mobile parts) making it prepared for information storage. That is the place firms like Twist Bioscience slot in. Twist specializes within the DNA synthesis course of, serving to to make DNA storage a actuality.
Some Key Gamers
Whereas a number of firms are actively making strides within the DNA information space for storing, Twist Bioscience boasts the flexibility to retailer as much as 215 petabytes of information in a single gram of DNA. For perspective, a single petabyte might retailer over 13 years of HD video footage. This implies Twist might retailer 28 centuries of HD video in a single gram of DNA. The newest from the corporate is that they’re engaged on a Proof of Concept (POC) chip and a tool that permits information to be written to DNA.
Early entry is anticipated to occur earlier than the top of this 12 months, although it’s unclear how mature the product providing will probably be by then.
Based in 2016, Catalog Applied sciences boasts buyers similar to Baidu, a Chinese language expertise conglomerate, and Horizons Ventures, a Hong Kong-based VC agency specializing in disruptive expertise startups. Catalog secured $35 million in Sequence B funding in late 2021, bringing their whole funding to $55 million. Whereas their platform “solely” has the capability to retailer one terabyte (1,000 gigabytes) of information per gram of DNA, Catalog’s benefit is that they’ve constructed a extremely scalable and safe platform for information storage. Primarily, they’re taking a unique strategy in specializing in practicality versus capability. They haven’t introduced a timeline for industrial availability of their DNA information storage providing and their web site doesn’t supply an excessive amount of confidence, claiming “the thought of storing info utilizing DNA has been round for some time. It’s simply that the price of DNA synthesis has been a bottle neck.”
Stunned to see this one on the record? We’re too. Nonetheless, Microsoft can also be on the forefront of the DNA information storage business, with a purpose of constructing it extra sensible and accessible for a variety of customers and functions. Their predominant contribution to the sector is the event of a completely automated system for DNA synthesis and coding, in partnership with Twist and Illumina amongst others. Dubbed the DNA Synthesis Platform (no creativity factors right here), it could actually encode giant quantities of information in a single run. Microsoft can also be creating a specialised algorithm for encoding and decoding DNA information, which follows a linear course of detailed under.
Whereas these firms discuss progress being made in the direction of commercialization, one firm claims to have already achieved commercialization.
In April of final 12 months, world biotechnology group GenScript (1548.HK) introduced the “first industrial platform for DNA digital information storage” which was validated by researchers who encoded “100 Mb of combined information sorts within the DNA to check the Excessive-Density DNA Synthesis Chip’s storage utility and retrieved 100% of the encoded information with no loss.” The press launch asserting the product providing stated that it might be “absolutely commercially accessible within the second half of 2022” and that they’re “actively searching for members for a partnership program to develop the applicability of the info storage platform.” No point out was made from whether or not this resolution can compete on value. If it could actually’t, then it’s laborious to see why anybody would wish to interact with their partnership program.
Competing on Price
DNA information storage isn’t addressing a blue ocean total addressable market (TAM). It must displace present options, specifically magnetic tape storage, which is without doubt one of the oldest applied sciences accessible for digital information storage. Whereas different storage applied sciences like solid-state drives have gotten well-liked for main storage and information processing, many organizations proceed to make use of tape storage merchandise as half of a bigger information administration technique.
Magnetic tapes have been offering a high-capacity, low-cost resolution for archival information storage since computer systems have been first invented. The primary magnetic tape storage system was invented within the late Nineteen Forties by Jack Mullin, an engineer from Santa Clara College, after observing the Nazi radio broadcasts of World Conflict II and realizing that they had a tool able to recording and reproducing sound. As a profitable electrical engineer, Mullin acknowledged the potential of this expertise and used it to create the inspiration of the magnetic tape storage we use to this present day.
An article by Community World talks about why tape storage isn’t lifeless citing value as a main issue.
Tape means that you can separate the medium from the recording system, which lets you purchase a handful of tape drives and 1000’s of tapes. These 1000’s of tapes additionally don’t want energy and cooling to take care of their information. In actual fact, some have instructed that even when disk was free it might nonetheless value greater than tape as a result of energy and cooling financial savings alone.

That final sentence is a really highly effective one, and it also needs to apply to DNA information storage which doesn’t want energy or cooling both (so we presume). Moreover, many don’t understand that tapes even have decrease error charges when writing information than another recording medium. “Tape is 1000X higher at writing ones and zeros than one of the best disk drive,” says the article, and 10X higher than solid-state drives. However on the subject of retrieval, the velocity of discs simply can’t be beat.
Tapes proceed to be the dominant resolution for secondary storage use circumstances the place information must be held for lengthy durations of time for as cheaply as doable. The article cites leisure and biotech as two industries which can be shopping for large tape libraries and filling them with 1000’s of tapes. This meshes nicely with the clientele Twist Bioscience appears to be concentrating on with their providing.
Alternatives for Disruption
So, what’s the benefit of utilizing DNA for information storage? Whereas tape storage is the present customary for archival information storage, it’s not with out its weaknesses. Catalog Applied sciences factors out that standard storage media “do not need the longevity, information density, or value effectivity to satisfy the worldwide demand.” Since magnetic tape can solely keep intact for 30 years, below optimum situations, DNA has potential to disrupt it within the archival storage market, because the excessive density and lengthy lifespan of DNA makes it optimum for this objective.
Moreover, retrieval velocity is a matter for tape storage. Tape drives have slower learn and write speeds than different storage units, with high-end speeds of solely a number of hundred megabytes (MB) per second. Retrieval instances may be affected by outdoors components similar to together with community bandwidth, information compression, and the general complexity of the info being retrieved. This makes tape superb just for information that doesn’t require frequent entry or pressing retrieval, similar to archiving. Within the high-performance computing market, the place the flexibility to retailer and retrieve giant quantities of information effectively is essential, DNA might be able to get a leg up if it could actually discover a solution to shorten its retrieval course of, however at what value? DNA information storage must compete with tapes on value, then with conventional laborious discs on velocity. Given GenScript is speaking about researchers storing and retrieving 100 megabytes efficiently, simply how distant are we from scalable economically viable DNA information storage options? Or is that this only a cool expertise resolution searching for an issue to unravel?
It’s About TAM Time
Calculating TAM for DNA information storage could be discovered by calculating the scale of the promote it’s seeking to disrupt, beginning with the archival information market. Twist claims archival information storage is a $35 billion market, nevertheless, the worldwide tape storage market was estimated at $4.3 billion in 2019, and in response to Allied Market Analysis, is simply anticipated to achieve $9.4 billion by 2030. If Twist expects to disrupt solid-state and laborious disc drives, perhaps they need to begin with the low-hanging fruit. Apparent bottlenecks embrace value, velocity, and complexity. If DNA storage fails to turn out to be aggressive with tape storage, there will probably be just about no TAM as a result of nobody in his proper thoughts would spend extra money to retailer information in a extra complicated approach. Whole value of possession wants to incorporate:
- The price of writing the info to a DNA storage medium (ought to be intuitively costly)
- The price of storing the DNA storage medium (ought to be zero)
- The price of studying the info (isn’t this simply the price of sequencing)?
Today, it prices $600 to sequence an entire genome which incorporates round 200 gigabytes of information or about $3 per gig. In the present day, magnetic tape expertise affords the bottom buy value of uncooked storage capability at round two cents per gigabyte, says Forbes. Certain, these are tough numbers, however we’re not satisfied DNA information storage may even come near competing on value anytime quickly. A key part of all the course of, the DNA information author, will probably be critically necessary in figuring out how value efficient all the course of will probably be, and Twist expects to permit early entry to this product providing later this 12 months.
Analysts ought to press the corporate relating to how distant these pilot merchandise are from being value aggressive. DNA information storage is simply a portion of Twist’s choices, however they tout it of their investor decks as the following largest factor. The one approach we’ll know they’ve developed an economically viable product is when the revenues begin to pour in.
Conclusion
On one hand, GenScript claims to have a commercially accessible product for DNA storage. Then again, they discuss the necessity to discover companions to advance their expertise. If it’s economically viable, companions ought to be discovering them. With the ability to retailer information on DNA may make for a fantastic occasion trick, however we’re not satisfied that it’s an economically viable resolution that may exchange tape drives which appear to be managing simply high quality. Till these firms begin offering velocity and price metrics that show they will compete with conventional information storage strategies, we’re not satisfied they’ve constructed something that’s economically viable for information storage wants.
