The short version

  • Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; Notion free plan limited to 1,000 blocks for 2+ member workspaces, restricting team usage
  • They diverge on capability: Memcached covers In-memory key-value cache, Notion covers Rich text editing with blocks.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

Notion

  • Free plan limited to 1,000 blocks for 2+ member workspaces, restricting team usage
  • Free tier only includes trial AI capabilities; full Notion AI requires paid plan
  • Page history limited to 7 days on free plan
  • Per-member pricing increases costs for teams compared to flat-rate competitors
  • Limited automation capabilities compared to dedicated workflow platforms

Memcached: Memcached or Redis?

Memcached is a pure cache: simpler, multithreaded and very predictable. Redis adds persistence, replication and rich data structures, which is why it is the default choice unless you specifically want a cache and nothing more.

Notion: What is the difference between Plus and Business plans?

Plus ($10/member/month) adds custom forms, unlimited file uploads, and 30-day history. Business ($20/member/month) adds Notion Agent for autonomous tasks, AI Meeting Notes, and advanced security features.

Source
Memcached: Does Memcached persist data?

No. Everything is in memory and lost on restart, by design.

Notion: How does Notion calculate billing when team members join mid-month?

New members added mid-month incur prorated charges for the current billing period and are included in future billings.

Source
Notion: What is the refund policy for Notion subscriptions?

New users receive a full refund within 3 days for monthly plans or 30 days for annual plans. EU/UK customers get a 14-day refund window per regional policy.

Source
Notion: What happens if a payment fails on my Notion account?

Failed payments are retried up to 8 times before the account automatically downgrades to the free plan.
