Hitachi Deskstar 7K1000 Terabyte Hard Drive

A Closer Look

A Closer Look
 
I'm not going to bother going into detail about Hitachi's OEM packaging for their HDD's as they are pretty much the same for all manufacturers'.
 
 Hitachi packaging
 
Releasing the Hitachi DeskStar 7K1000 from the confines of its plastic packing shroud, we can see that there isn't really anything particularly different here from any other regular HDD - other than the increased thickness to accommodate those extra disk platters and heads.

Continuing our quick trip around the outside of the Hitachi DeskStar 7K1000 we can see the familiar 4-pin power connector, SATA power connector and SATA cable plug. The Hitachi DeskStar 7K1000 is also missing the jumper pins for SATA 1.5 - 3.0 GB/s operation.

Flipping the Hitachi DeskStar 7K1000 over we can see the Logic Board and the brains behind the brawn. The Hitachi DeskStar 7K1000 uses an Infineon UAB-M3064-S V2.0 Controller. The Controller is in charge of everything: exchanging data between the hard drive and the computer, controlling the motors on the hard drive and commanding the heads to read or write data, etc.

The Hitachi DeskStar 7K1000 features 32MB of cache memory courtesy of the MT 48LC16M16A2 memory IC. Also known as the buffer, these chips have an ultimate role in the hard drive performance. The higher its capacity, the faster the data transfer between the drive and the computer should be.

Great review m8.

What I draw exception to on harddrives these days, and not this one in particular, is that the mounting holes on the left and right side that astride the pcb mount still do-not protect the pcb from screws being used that are too long.

To the rear of the drives (the non pcb) there is an enclosed space where the screws can draw into and then hit if they`re too long.

As an example I mounted a 1TB WDC drive, to which the makeup is almost exactly the same as this drive according to the nice pics. In moving the drive from one cage to another I happened to use case-style screws and 1 of them happened to be millimeters longer than the others. As a result it was shorting something on the non visible side of the pcb.

On boot, the mobos I tried it on (whilst keeping it in the same cage) reported "disk not reset info!" or similar, taking it out of the cage completely it went through ok, on doing so I noticed the 1 screw was that much longer than the rest - hey a case-type screw is a case-type screw.

All it requires is an enclosed area like the rear two screw-holes have and it saves a bunch of trouble. It`s not like the harddrive people always enclose screws for u, so u often delve into the "similar screws" box u have laying around.

Meh, the drives are great performers tho, can`t argue with that.Quote

Thank you mate and I totally agree, it leaves next to no margin for error.Quote
