Pros: Fastest Biggest yet. Seagate announced a 750mb/7200/9.5mm drive months ago and it's been delayed until the end of the year. I got tired of waiting and so I jumped on this as soon as it was released. Here are some hard numbers: SS=Samsung HM640JJ , SG=Seagate ST9640320AS 5400/640mb/2.5", WD=Western Digital WD1001 7200/3.5" desktop drive sequential read/write mb/s SS 112/106 SG 89/86 WD 111/109 Random 512kb read/write mb/s SS 36/40 SG 35/41 WD 47/68 Random 4kb read/write mb/s SS .910/.910 SG .815/.774 WD .766/1.711
FAST FAST FAST
Pros: Very fast. Using in an HP Envy 17, I7 processor. 7.7 Windows gives it a 7.7. Previous fastest was a Seagate 750gb 7200rpm gave a 5.9. Crystal Disk Mark scores: * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 247.422 MB/s Sequential Write : 228.001 MB/s Random Read 512KB : 186.844 MB/s Random Write 512KB : 220.442 MB/s Random Read 4KB (QD=1) : 11.835 MB/s [ 2889.3 IOPS] Random Write 4KB (QD=1) : 22.569 MB/s [ 5510.0 IOPS] Random Read 4KB (QD=32) : 129.109 MB/s [ 31520.7 IOPS] Random Write 4KB (QD=32) : 73.612 MB/s [ 17971.7 IOPS] Test : 1000 MB [C: 74.1% (39.1/52.8 GB)] (x5) Date : 2011/02/21 20:46:35 OS : Windows 7 [6.1 Build 7600] (x64)
Cons: 1) Firmware upgrade formats the disk 2) Have to use a DOS bootable USB drive to load firmware. In this day and age, DOS???? It took me forever to find a DOS boot for USB. Come on Samsung. Atleast include a boot USB for your upgrades.
Overall Review: Very Expense. The problem I have found is that the disk is not bottle neck. Sure boot time is fast (20s) but I have always just let the computer boot while I got my diet coke so it's not big deal. It still bottle necks with multiple apps running and processors show less than 5%. The problem is still getting data to the processors and back out, we still need a bigger pipe.
Outstanding Laptop Drive
Pros: Fast, cool, quiet. It's as good as it gets. I have had the 500gb 72k drives, the Samsung 640gb 72k, and now a pair of these. The best drive made.
Overall Review: The previous posts regarding HD recognition are the OS's fault, not the HD. Obviously technically challenged people or they would not have posted the negative response. Windows 7 recognizes the drive and has the correct drivers for it. Any Windows OS prior does not recognize AHCI drives and so you will need to load the driver at OS installation. DOH
