El *german revista *c'*t (*http://*ct.*de) Justo probado el nuevo *USB3.0
externo 4TB *Seagate *STAC4000200 *GoFlex, el cual tendría que ser sobre el
más rápido 3.5", 7.2*k *min^-1 *SATA el paseo actualmente disponible.
Sostenido lee  (*min/*avg/*max): 84 / 138 / 178 *MByte/*s
Sostenido escribe (*min/*avg/*max): 50 / 101 / 177 *MByte/*s

el Problema es, el disco no tiene #ninguno #seguidor y después de 100 GB o así que consigue tan caliente
(63°*C) que escribe las velocidades bajan a 50 MB/*s como el disco  un "leído
después de escribir" cuándo consigue tan caliente ...

The german magazine c't (http://ct.de) just tested the new USB3.0
external 4TB Seagate STAC4000200 GoFlex, which should be about the
fastest 3.5", 7.2k min^-1 SATA drive currently available.
Sustained reads  (min/avg/max): 84 / 138 / 178 MByte/s
Sustained writes (min/avg/max): 50 / 101 / 177 MByte/s

Problem is, the disk has no fan and after 100 GB or so it gets so hot
(63°C) that write speeds go down to 50 MB/s as the disk does a "read
after write" when it gets so hot ...

HTH,
