Interface Bandwidth And Access Time
Interface Bandwidth
This benchmark is used to verify the interface claims of drive manufacturers. Clearly, the Hitachi Travelstar 5K500 and 5K320 utilize Serial ATA 3 Gb/s, as they reach 160 MB/s. The Samsung Spinpoint M6 HM500LI stays at 127.7 MB/s.
Access Time
The Samsung HM500LI is as bad in the access time test as it was good in the data transfer benchmarks: 19 ms is a new record on the low side. However, the two Hitachi drives aren’t all that great either, at 18 and 18.5 ms.

The article says there is a 2.5" 320GB PATA drive - what is it? The largest I've seen is the WD2500BEVE.
TYPO:: Your article mistakenly say Hitachi Deskstar when it should say; "Hitachi Travelstar", all throughout all the benchmark results...
Terry, I too have not heard of a laptop drive larger than 250GB that is PATA.
Samsung has now brought down the height back down to 9.5 mm at this capacity point.
-_-
Platters 2 3 3
shouldn't it be 2 for the Samsung?
and
Interface SATA 3 Gb/s SATA 3 Gb/s SATA 3 Gb/s
shouldn't it be 1.5 for the Samsung?
Patrick and Achim,
try setting the drives to sata 1.5gbs instead of 3.0. the single drives do not need that much interface bandwidth, but the 3.0 interface uses more power.
Terry--you are absolutely correct. Reference fixed to reflect your observation.
Dan--We're fixing the charts right now and will have them updated as soon as they are ready.
Magic--Axed the redundant "down"
Hrod--according to the story's author Samsung's original launch documentation said 2 platters and 1.5 Gb/s. It has since been fixed and everything in the piece updated to reflect that the Spinpoint is actually a three-platter device with a 3 Gb/s interface.
Thank you for the feedback guys!
Guys why arent these HDD's on the charts, they have been reviewed by you and are close to the 2nd and 3rd fastest disks...?

It would be nice if the Samsung drive wasn't such a power hog - I would love to have a fast 500GB drive in something like a HP mininote for using as a portable movie player. But getting 1.5TB raid 0 in a Clevo D900 now doesn't sound bad either...
A nice detailed review as usual.
Any chance that you could do a review of 2.5" 7200rpm 320GB HDDs. I believe Hitachi, Seagate, Western Digital, and Samsung all have them now. I'm waiting for someone to do a comprehensive review before buying one to upgrade my laptop. I would think that Hitachi's might be the fastest given the performance of the 7k200, but I've been hearing good things about the WD 320GB Black so I guess we'll see.
Two errors: the opening paragraph claims that Samsung's 500 GB drive uses two platters, when it actually uses three (however, the detail page for this product gets it right).
Also, 12.5mm was not the "initial" height of laptop drives -- there was a point in time when those were considered the slim ones, as there were 17mm and 19mm height drives before them (I used SCSI models in my PowerBook). Searching for "19mm laptop drive" will verify this.
How long do you think it will take for these issues to get worked out?
