File storages for users

Introduction Until recently, PC buyers had very little choice for what kind of file storage they got with their laptop, ultrabook, or desktop. If you bought an ultrabook or ultraportable, you likely had a solid-state drive (SSD) as the primary drive. Every other desktop or laptop form factor had a hard disk drive (HDD)

Advantages and Disadvantages Price Maximum and common capacity Speed Durability Availability Form factors Noise

Price For the same capacity and form factor 1TB internal 2.5-inch drive, you'll pay about $75 for an HDD, an SSD is a whopping $ cents-per-GB for the HDD 60 cents-per GB for the SSD

Capacity As seen above, SSD units top out at 1TB, but those are still very rare and expensive. You're more likely to find 128GB to 500GB units as primary drives in systems. You'd be hard pressed to find a 128GB HDD in a PC these days, as 250 or even 500GB is considered a "base" system in Multimedia users will require even more, with 1TB to 4TB drives as common in high-end systems.

Speed This is where SSDs shine. An SSD-equipped PC will boot in seconds, certainly under a minute. A hard drive requires time to speed up to operating specs, and will continue to be slower than an SSD during normal operation. A PC or Mac with an SSD boots faster, launches apps faster, and has higher overall performance.

Durability An SSD has no moving parts, so it is more likely to keep your data safe in the event that you drop your laptop bag or your system is shaken about by an earthquake while it's operating. Most hard drives park their read/write heads when the system is off, but they are flying over the drive platter at hundreds of miles an hour when they are in operation. Besides, even parking brakes have limits. If you're rough on your equipment, a SSD is recommended.

Availability Hard drives are simply more plentiful. Look at the product lists from Western Digital, Toshiba, Seagate, Samsung, and Hitachi, and you'll see many more HDD model numbers than SSDs. For PCs and Macs, HDDs won't be going away completely, at least for the next couple of years. You'll also see many more HDD choices than SSDs from different manufacturers for the same capacities. SSD model lines are growing in number, but HDDs are still the majority for storage devices in PCs.

Form factors Because HDDs rely on spinning platters, there is a limit to how small they can be manufactured. There was an initiative to make smaller 1.8-inch spinning hard drives, but that's stalled at about 320GB, since the MP3 player and smartphone manufacturers have settled on flash memory for their primary storage. SSDs have no such limitation, so they can continue to shrink as time goes on. SSDs are available in 2.5-inch laptop drive-sized boxes, but that's only for convenience, as stated above.

Noise Even the quietest HDD will emit a bit of noise when it is in use from the drive spinning or the read arm moving back and forth, particularly if it's in a system that's been banged about or in an all-metal system where it's been shoddily installed. Faster hard drives will make more noise than slower ones. SSDs make virtually no noise at all, since they're non- mechanical.
