Hack7MC पर एक लेख मेरी आँखों दो महीने पहले पकड़ा, लेकिन मैं सिर्फ इस पर निम्नलिखित के लिए चारों ओर मिला है. विचार एक सस्ते के लिए अपने पुस्तकालय को ले जाकर मीडिया केंद्र के लिए मीडिया ब्राउज़र प्लगइन तेजी लाने के लिए है यूएसबी फ्लैश ड्राइव, जो उम्मीद है कि सामान्य हार्ड डिस्क ड्राइव की तुलना में बेहतर प्रदर्शन प्रदान करता है. The first thing I did was test a couple of flash-based devices that I have against my desktop HardDrive…

WD Velo­ciRap­tor (300Gig)
ran­dom 4k read = 0.9mb/s
ran­dom 512k read = 57mb/s

Super Tal­ent Pico‑C 8Gig
ran­dom 4k read = 8.2mb/s
ran­dom 512kb read = 34.6mb/s

SanDisk Extreme III SDHC 8Gig
ran­dom 4k read = 4.6mb/s
ran­dom 512kb read = 20.45mb/s

–update
Cor­sair Flash Voy­ager 8Gb
ran­dom 4k read = 8.13mb/s
ran­dom 512kb read = 30.41mb/s

I have been led to under­stand that the 4k meas­ure­ments are the most import­ant val­ues, how­ever I would like an explan­a­tion of why this is the case.

The aver­age file size in my media browser image lib­rary is ~42kb so they are rel­at­ively small files, which I believe is relevant

For com­par­is­on of a lot more pen drives there is a recent review (2009) पर Ars Tech­nica

The cor­sair drive from the ars review is cur­rently on ebay for around £16 — I won­der how much of a per­form­ance increase it offers

–update

  • The cor­sair drive from the ars review turned out to be frac­tion­ally slower (effect­ively on par with) the Pico‑C
  • The aver­age files in my Media Browser lib­rary are now 610kb. They range from 5kb to 2mb.
  • यूएसबी 2.0 is the­or­et­ic­ally lim­ited to 60mb/s, and in prac­tice seems lim­ited to 30mb/s
  • Without यूएसबी 3.0, or an intern­al (e.g. SATA) एसएसडी I am skep­tic­al that any real­ist­ic speed-up can be gained with this meth­od. Using an एसक्यूएल data­base for Media Browser may offer a sub­stan­tial speed up, and the data­base can eas­ily be hos­ted on a राम drive for an addi­tion­al increase
