Head-to-Head Comparison
STRG vs Backblaze B2 Pricing (2026)
Backblaze B2 has the lower headline storage rate ($6.95/TB against $6.80/TB) and makes the first three times your stored volume of egress free each month, then bills $0.01 per GB. STRG charges nothing for egress at any ratio. The engine prices STRG at $33.93 against B2's $34.75 at 5 TB stored and 5 TB served, and STRG stays ahead across every workload we price, including the ones where B2's 3x allowance is fully used ($347.50 against $339.93 at 50 TB stored and 150 TB served). B2's case is the lower per-terabyte rate and an established multi-region footprint; STRG's is that the egress meter never starts.

Cost profile: where each provider wins
What STRG is good for 🏆 Gold Standard
- ✓ $6.80/TB flat with unlimited $0 egress at any ratio
- ✓ $0 standard Class A and Class B request fees
- ✓ Cheaper than B2 at every priced workload, including $339.93 against $347.50 at 50 TB stored and 150 TB served
Constraints to plan around:
- ! Two regions only
- ! No published availability SLA figure
What B2 Cloud Storage is good for
- ✓ $6.95/TB, the lower headline storage rate of the two
- ✓ Free egress up to 3x stored volume every month
- ✓ No minimum retention period, so short-lived objects cost only their storage time
- ✓ US-West and EU regions, with the longer operating record of the two
Constraints to plan around:
- ! Egress beyond 3x stored bills $0.01 per GB, which is why the total overtakes the flat rate
- ! The lower headline rate does not survive the egress allowance limit
