How To Get wiper.sh Running On QNAP Storage Devices To TRIM SSDs?


Maybe that’s why the SSD write test on TS-112 and TS119PII are slower than traditional hard drive. Need to enable trim in QNAP. For Linux kernel 2.6.33, trim is disabled by default.

Since I stick my Intel SSD X25-M G2 160GB into my QNAP TS-459 Pro the performance started to decrease due to the absence of a garbage collector, aka TRIM.

Indeed if a SSD doesn’t trim, then every write to a previously written block must first be read, erased, modified, and re-written to the same location thus crippling write performance.

Since I have run quite some benchmark tests, and massively copied large files such .vmdk and .iso files and deleted them all afterward, the write performance got lower and lower.

My TS-459 runs a Linux QNAPNAS02 2.6.33.2 which does support natively TRIM function but I was sad to learn that while it’s available, it is not used at all because it is inadequate for today’s real TRIM hardware. This is not a QNAP problem but an issue with the Linux kernel developers. In the interim Mark Lord, who’s by the way one…

Upgrade my iBook G4 with a SSD


I have upgrade my iBook G4 to SSD on 2013/10/11 Fri. The disk access feels much faster than the internal 4200RPM IDE or an external FireWire 7200RPM 3.5″ WD 160GB IDE. My left hand also feels much cooler when typing on this notebook.

Here is the disk test result by Xbench 1.3 on MacOS 10.3.9. The bottle neck should be IDE and the SSD to IDE convertor. A SSD with native Sata 2/3 will perform even better. Compare to other IDE drive, the transfer rate is improved. Also, the SSD should perform better on access time than hard drive.
