The catch
QNAP TS-264-8G-US
A two-drive mirror takes up both SATA bays.
Side by side
QNAP TS-264 vs TS-464: 464 gains HDD bays while the selected 8G networking stays put
Quick verdict
The TS-264 is right when a two-drive mirror meets your storage plan. The TS-464 is right when you need more SATA drives inside the same chassis. Two 2.5GbE ports, two M.2 slots and a PCIe expansion slot come on both 8G configurations, so the extra bays are the main hardware reason to move up.
Before you buy
Why, and what it costs you
A two-drive start leads to a different next step
After starting with two drives, TS-464 still has two empty SATA bays and TS-264 has none.
Where this comes from
Two bays are left by four minus two, and zero by two minus two. Migration is still subject to QTS storage rules.
The catch
QNAP TS-464-8G-US
M.2 sockets do not come from extra bays.
QNAP TS-264-8G-US
- Why pick it
- Set up a small two-drive mirror
- Stay with the dual 2.5GbE ports as they are
- The catch
- A two-drive mirror takes up both SATA bays.
QNAP TS-464-8G-US
- Why pick it
- Have space for more SATA drives down the road
- Run a layout that needs more than two SATA drives
- The catch
- M.2 sockets do not come from extra bays.

In practice
Differences you will notice
A two-drive start leads to a different next step
After starting with two drives, TS-464 still has two empty SATA bays and TS-264 has none.
How we worked this out
Two bays are left by four minus two, and zero by two minus two. Migration is still subject to QTS storage rules.
A bigger model will not speed up one cable
Each built-in socket on both models gives a 2.5GbE link.
How we worked this out
Combining two physical ports into one faster single-client transfer does not happen automatically.
NVMe and networking trade off against SATA growth in different ways
Whatever the SATA bay count, both models keep two onboard M.2 slots and one PCIe slot.
How we worked this out
SATA positions double on the four-bay chassis, but the listed M.2 and expansion slots do not.
Option A
QNAP, TS-264-8G-US
QNAP TS-264-8G-US
This two-bay NAS has two built-in NVMe slots, dual 2.5GbE and a PCIe slot that takes supported SSD or network expansion. The current 8G configuration selected here comes with 8 GB RAM.

- Expansion over PCIe: One Gen3 x2 slot
Option B
QNAP, TS-464-8G-US
QNAP TS-464-8G-US
A 4-bay chassis whose fastest documented network path is 2.5 Gbps.

Spec by spec
Where they really differ
| Spec | QNAP TS-264-8G-US | QNAP TS-464-8G-US | In practice |
|---|---|---|---|
| Internal SATA bays | 2 | 4 | Room for later drives differs after a two-drive start. |
| Built-in Ethernet | Two 2.5GbE ports | Two 2.5GbE ports | Moving to the larger chassis leaves single port speed unchanged. |
| M.2 NVMe slots | 2 | 2 | NVMe sockets are not increased by extra SATA bays. |
| PCIe expansion | One Gen3 x2 slot | One Gen3 x2 slot | For 10GbE, each needs an optional compatible card. |
| Selected base memory | 8 GB | 8 GB | Capacity at the start is identical for the compared 8G packages. |
| Internal SATA-only RAID 6 | Two SATA bays do not meet the four-disk minimum | Four SATA bays meet the minimum with four compatible drives | Protection against two drives failing, as a four-drive RAID 6 array offers, is beyond a two-HDD mirror. |
Trade-offs
What each pick costs you
With QNAP TS-264-8G-US
- 10GbE takes a card plus a compatible network path.
With QNAP TS-464-8G-US
- 10GbE cannot be had without a compatible expansion card.
Change of plan
When the answer changes
I require more than two internal SATA drives
Go with QNAP TS-464-8G-US. Four bays are on TS-464.
My plan is covered by two mirrored HDDs
Go with QNAP TS-264-8G-US. That configuration comes with TS-264.
I need 10GbE included in the original package
Neither model fits. A compatible adapter bought separately is needed on both.
Decision guide
How to decide
A two-drive start leads to a different next step
If adding internal drives is already part of the plan, choose the TS-464. The TS-264 can still serve a two-drive mirror, but growing inside the original chassis would mean replacing existing drives. Empty bays on their own do not guarantee a smooth RAID migration, so check the supported transition and keep a separate backup before changing the array.
A bigger model will not speed up one cable
Moving to four bays does nothing to the built-in port rating, so it will not cure a slow wired workstation. Look at the client adapter, switch and storage workload first. Link aggregation or multichannel needs the appropriate complete configuration, and neither is assumed here. Pick the larger NAS for its storage layout, and budget for networking on its own.
NVMe and networking trade off against SATA growth in different ways
Either hardware layout can support a mirrored NVMe pool and a compatible 10GbE card. The TS-464 adds SATA room around that plan. If two HDDs are enough, choose the TS-264 and do not expect the larger model to supply more M.2 slots or a built-in 10GbE connection. Verify the selected card and drive compatibility.
