QNAP TS-251 with Firmware 0612 and 8GB RAM File Transfer Performance Report


Last time, I test QNAP TS-251 with Firmware 0605 and only one hard drive. Here, I am going to run the same test again but with Firmware 0612, two hard drives as RAID 1, and 8GB RAM. I can see the 64-bit QTS is capable to identify 8GB RAM without any problem.

Anyway, let’s see if it could outperform other Intel Atom processors on file transfer!

Processor and RAM Difference

TS-251 has a J1800 at 2.41GHz burst to 2.58GHz; N2560 has a CE5335 SoC at 1.6GHz; TS-112 is based on a Marvell 88F6282 SoC at 1.2GHz; TS-119PII and TS-212P are Marvell 88F6281 at 1.6GHz and 2.0GHz respectively; TS-269L is Atom D2701 at 2.13GHz; N2310 has a single core APM86491 running at the lowest 800MH.

J1800 is based on Bay Trail which is part of the Atom family. It has 2 cores but without hyper-threading technology which means it may serve only 2 threads concurrently. The 1MB cache size is still the same to D2700 but officially support for 8GB RAM which is double to D2700. CE5335 SoC and D2700 are based on Berryville and Cedar Trail respectively. Both have 2 cores with hyper-threading technology. The former has 512KB L2 Cache and supports 32-bit physical addressing while the latter has 1MB and supports 36-bitAPM86491 is based on Power465 with FPU and has 64KB L1 cache with 256KB L2 Cache. Marvell 88F6282 SoC and Marvell 88F6281 both have 32-bit instruction set.

Both TS-251 and TS-269L come with 1GB. TS-251 is expandable to 8GB while TS-269L is 3GB. The 64-bit QTS could manage RAM beyond 4GB. TS-119PII, TS-212P, and N2310 are fixed to 512MB;  N2560 is 2GB; TS-112 is just 256KB.

Test Method

I connect NAS to computer directly, use the same test sample in File Transmission with Different Sharing Solution on NAS, and use Linux command mount for better performance.

Two protocols are used in this test: Samba and NFS. You may learn more about how to setup the test with NFS and Samba to do your own test.

TS-251 is configured with Seagate Desktop HDD 500GB * 2 as RAID 1 and with 8GB and 1GB configurations. Others are listed in comparison table.

According to my MTU test, I keep it to use default 1500.

I also add test result from following as reference:

Analyze

TS-251 with RAID 1 and 8GB RAM reads much better than single drive on both Samba and NFS transfer. On the other hand, RAID 1 writes are faster with 1GB than 8GB RAM. It seems RAID 1 helps on reading but more RAM is not always good on writing.

TS-251 with RAID 1 is significantly faster on reading than TS-269L. But TS-251 with RAID 1 and 8GB RAM is slower on writing than TS-269L, while TS-251 with RAID 1 and 1GB RAM is faster on Samba and almost the same on NFS.

Except for TS-269L, TS-251 with RAID 1 is faster than any other devices on every item.

Other Thoughts

It seems you better use RAID 1 than single drive with TS-251. More RAM is not always better on writing tests.

During 40 tests, the mount drive lost connection without any reason nor warning once. I have to reconnect and run the test again. Because I cannot repeat this issue, I have no ideas what happen.

For file transfer, if you need more reading speed, get more RAM and use RAID 1 on TS-251!
