A coding agent can fill a laptop quickly. Repos, package caches, container images and half-finished branches pile up until the machine bought to move faster starts demanding deletions. Prized, a Y Combinator-backed startup selling cloud dev boxes for AI agents, thinks the answer is to stop treating local disk as the limit. Its new Infinite storage option keeps a box's files in Amazon S3 and caches active files on the machine, letting a box grow to 40 TB.
The company announced the feature in a blog post, saying the storage works with Docker and behaves like a local disk for everyday work. The pitch targets people running Claude Code, Codex and other agents that keep going after a laptop closes.
Introducing Infinite Storage on Prized
Infinite is a marketing name rather than a literal promise. The 40 TB ceiling applies only to Prized's Extra Large box. Smaller sizes get 3 TB to 20 TB of total storage, and the option starts at Extra Small. Prized says the home directory, /srv and Docker live on the new layer, while /tmp and system packages stay on the ordinary disk.
The design is familiar: write locally, upload to object storage in the background, and pull data back on a cache miss. Prized says its Keep layer does that, using the machine's disk as cache. The risk is a cache miss, when an agent opens a repo or container image that is not warm. Prized argues that active files stay cached, so the slow path is less common than it sounds.
Prized tested on identical m6a.xlarge boxes in Oregon against EBS GP3, Archil, EFS and JuiceFS. Extracting Linux 6.12 took 3.73 seconds on Infinite storage, 3.85 on EBS, 49.2 on Archil, 1,717 on EFS and 2,608 on JuiceFS. A warm pnpm install finished in 0.82 seconds, against 1.2, 15, 134 and 51.4. A Docker build took 81.6 seconds on Prized and 88.9 on EBS; Prized says the three network systems could not complete it.

The restored-box test is more striking. The first recursive grep of the Linux source tree took 34.4 seconds on a fresh Prized box with an empty cache, according to the company, and 364 seconds on an EBS volume initialized from a snapshot. That gap depends on how each system warms up, so treat it as a sign of Prized's engineering focus rather than a universal comparison.
Those numbers are vendor-run. Prized chose the hardware, commands, storage settings and number of runs, and has not published an independent reproduction. The network-storage figures also use particular versions and defaults, which makes them useful for spotting large gaps but not for ranking every deployment of EFS or JuiceFS.
The cost is simple. A box's monthly price includes its normal disk. Extra storage costs $0.05 per GB-month, awake or asleep, measured after compression. A terabyte is $50 a month, against $70 for GitHub Codespaces, $80 for EBS and $300 for EFS on list prices. Filling a 40 TB Extra Large box means paying for roughly 38 TB beyond its included disk, or $1,900 a month before compression.
The bigger shift is in how dev boxes are sold. Agents run for hours, leave caches behind and often need more than one machine. Storage that follows the box and survives a closed laptop is useful. But 40 TB does not solve the hard part by itself. The real test comes after weeks of work, when the cache is cold, the bill is visible and an agent asks for a file nobody has touched in a month.
