想买个120G的硬盘，有没有推荐的？稳定性第一主要用来存东西的，所以主要要稳定，要不然用不长就容易坏的可不好了。
Seagate Savvio
HDS is also a good choice.
Yeah!
Seagate Savvio
Yeah!
have you used it before?1. it is either 37GB or 74GB
2. it uses ultraSCSI 320 interface. a typical ultraSCSI 320 controller costs around $600
3. it's based on 2.5' design, what for?
4. 10000+ rpm SCSI disks sound like 电锯 when they're running
5. as far as reliability is concerned, Savvio is too new, therefore it's not been tested through by the public.
Of course I never used, but your argue is not so strong
But as he is only concern on reliability, Savvio is a good choice. Actually LTO/DLT should be better, but this guy ask for HDD, not tapes.
Space limit or cost is the must trade-off for guarantee reliability. Server HDD use more advanced techniques to ensure it from both design and implementation point of view that's why the space is limited and the cost is increased.
2.5-inch disc is better than 3.5-inch from design point of view as it have shorter seeking time (This is obvious as the seeking distance is shorter) and more important, more reliable as less repeatable runout (RRO) will occur (This is not so obvious but think it in this way, RRO is majorly caused by the air-flow caused by disc spinning, smaller disc cause less air-flow, thus less RRO). Generally the smaller is surely better
For electrical-saw-like sound, I don't know where you get this idea, but I can tell you this is completely wrong. I had ever drived one 5400RPM desktop hardisk (or even worse one, I'm not quite sure) to spin on 10000RPM in DSI and I never got this kind of sound. Thus I don't believe a special-designed and tested spindle motor will be worse than that. I guess the sound may comes from the brake -- you may know server HDD usually implement disc brakes to stop disc from spinning when your turning off the machine.

i am just telling the truth1. maspero was asking "想买个120G的硬盘，有没有推荐的？”，therefore savvio's 37GB or 74GB available capacities are certainly out
2. i don't care what you did to spin a 5400rpm disk to 10000rpm and whatever accoustic result you got from it. i've been doing my IA in seagate and physically used all kind of SCSI disks. "10000rpm+ SCSI harddisks sound like 电锯" is both from my own experience and from the engineers who actually designed it. SCSI harddisks are mainly for servers which resides in a server room, whether they sound like a whisper or 电锯 is not a concern.
3. i am not saying 2.5' disks are not good. what i meant was spending tens of times of money on SCSI 2.5' harddisks than ordinary IDE 3.5' harddisks are of no point for a desktop system. by the way, your missed out one important point, smaller disk means less seek time but at the same time, in order to increase the relatively lower transfer rate (as compared to normal 3.5' design), the rpm must increase, which leads to m (more...)
Ok, then I'm wrong, I believe you,
But I'm very sure that Seagate and HDS are recommended by DSI professionals, don't know whether because they are business partner with DSI or not.
