Seagate Momentus 7200.3 ST9320421AS 320 GB

Advantages: Small, fast, large cache
Disadvantages: Expensive

...times. So overall it performs well. Seagate are a trusted manufacturer and have been around for a while. As far as I'm aware they have never made a bad device line, but then my HDD's of preference are normally Western digital. The device uses an 8mb cache, this isn't a special as it used to be since many other 2.5"HDDs now use this amount but its still a plus point for the device. It runs a 7200RPM, this is about the same as many normal 3.5" HDDs but is quite fast for a laptop variant. As I said before it is important to look at your need for this type of device, there are many other devices available that do the same job but for a far lower price. You should only buy 2.5" HDD's if you really need one and if you can't use anything else. I bought this one new from Ebuyer for just over £100 inc VAT and delivery. Its now happily running...

Advantages: Fast except multithread read,good capacity, stable, 5 years warranty
Disadvantages: Weak at multithread/multiple reads, a little noisy

...I've used a similar model for a long time and I have mixed opinions about 7200.10 hard drives. The good things of Seagate Barracuda 7200.10 Seagate hdd are the most stables drives in the market, I've used my drive for quite a time and never experienced a single problem. Large capacity, 320 GB is more than enough (300 Gb real) Good speed, especially at writing data, but also at reading excepting multiple file copy. Speed is about 75-80 Mb at large files The access time is about 13-14ms (about the same as other hdd) Temperature IS OK. Very stable and reliable The not so good things: Multitasking read performance. While on single thread the performance is high, 75 Mb, while increasing the threads, many aplications used the speed drops at about 5-10 Mb A little noisy especially when many aplications are used Conclusion. Good hard drive... Read review

Advantages: Fast, new Perpendicular Technology, very quiet, fair price
Disadvantages: Not keen on cloning software available from Seagate

...The 7200.10 hard disk drives from Seagate are the first to use new Perpendicular Technology for recording data. This makes them, in theory, faster than other hard disk drives. This is because the drive head has less far to move in order to record/retrieve the same amount of data. I have recently purchased the 320GB ATA100 version and I do notice slightly higher speeds compared to my previous Seagate Barracuda 7200.9 80GB drive. Official reviews claim that the seek noise is higher with the 7200.10 than 7200.9, and higher than the majority of other leading drives. However, I cannot personally hear it seek at all, even when the drive is very busy. I do have a well insulated case but I am still able to hear the internal fans and another older hard disk I have. The reviews I've seen give very favourable figures for the spinning noise, which... Read review
