Western Digital MyBook Essential Edition 500GB (USB) vs. Seagate FreeAgent 500GB (USB)
My two cents -
WD: (not the Essential Edition 2.0) Disk model: WD5000AAJB (8MB cache, PATA?) Format: FAT32 1 year warranty (extend for 2 additional years for an additional $25) Ventilation via convection holes on top and rear and bottom (but no fan) On/Off switch with LED circle (in addition to Auto power management) on front. Don't turn it off accidentally while writing Additional LED on power supply My test under Win XP- Sequential Read: 29 MBytes/sec Sequential Write: 18 MBytes/sec Paid $130 (Staples, 9/2007) Seagate: Disk model: ST3500830AS (8MB cache, SATA?) Format: NTFS 5 year warranty Ventilation holes at the bottom? Cool-looking LED bar that glows brighter during use Mini-usb connector on drive end My test under Win XP- Sequential Read: 27 MBytes/sec Sequential Write: 24 MBytes/sec Paid $120 (Office Depot, 9/2007) WD's DLGDIAG v1.07 reads the S.M.A.R.T. parameters from the Seagate external USB drive! I thought SMART of USB drives was not accessible? |

On/Off switch with LED circle (in addition to Auto power management) on front. Don't turn it off accidentally while writing Additional LED on power supply My test under Win XP- Sequential Read: 29 MBytes/sec Sequential Write: 18 MBytes/sec Pretty standard for USB2. Paid $130 (Staples, 9/2007) Seagate: Disk model: ST3500830AS (8MB cache, SATA?) Format: NTFS 5 year warranty Ventilation holes at the bottom? Even worse... Cool-looking LED bar that glows brighter during use Mini-usb connector on drive end My test under Win XP- Sequential Read: 27 MBytes/sec Sequential Write: 24 MBytes/sec Again, pretty standard. Paid $120 (Office Depot, 9/2007) WD's DLGDIAG v1.07 reads the S.M.A.R.T. parameters from the Seagate external USB drive! I thought SMART of USB drives was not accessible? Because some babblebot never tires to babble the same stupidity around? It is not in any standardized way. What exactly did you not understand in " *WD's DLGDIAG* v1.07 reads the S.M.A.R.T. para- meters from the *Seagate* external USB drive!" Babblebot? But individual USB-(S)ATA bridges may well include non-portable vendor extensions to do it. Or use perfectly standard passthrough extensions. That means you are stuck with some specific software to read it. No different with device drivers that don't support S.M.A.R.T. driver extensions. No automatic monitoring, unless the specific software supports it. No different with "the specific software" that depends on the drivers for SMART driver extensions. No monitoring when the specific software breaks. For example, no monitoring under Linux, Solaris, FreeBSD, MacOS-X, etc.. With a standardized interface you get all that. Arno |

Can you run USBview and tell us the vendor and product IDs of the bridge chips?

WD: idVendor: 0x1058 idProduct: 0x0901 ST: idVendor: 0x0BC2 idProduct: 0x3000 Thanks. I was hoping that the IDs would identify the chips rather than the manufacturer of the HD. Then again, maybe the chips are manufactured by or for Seagate and WD, respectively. The reason for my curiosity is that I have tried two different enclosures, one using a JMicron JM20337 chip, the other a Prolific PL3507, but neither works reliably with my Win98SE/SiS7001/7002 box. FYI, here is a list of USB IDs: http://www.linux-usb.org/usb.ids - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

But then 'again', "pretty standard" has a broad range with you, isn't it, bb. Paid $120 (Office Depot, 9/2007) WD's DLGDIAG v1.07 reads the S.M.A.R.T. parameters from the Seagate external USB drive! Does it also read the temperatures and if so what are they (after a little workout)? I thought SMART of USB drives was not accessible?
