In 2007, the OLPC XO-1В used a 1GB SSD, and the Asus Eee PC 700 series used a 2GB SSD as primary storage. The first primary drives that we know as SSDs started appearing during the rise of netbooks in the late 2000s. Current flash memory is the logical extension of the same idea, as it doesn't require constant power to retain the data you store on it. Technologies like bubble memoryВ flashed (pun intended) and died out in the 1970s and 1980s. The SSD has a much shorter history, though its roots do reach several decades into the past. Current 3.5-inch hard drives are now available in capacities exceeding 10TB. Capacities have grown from multiple megabytes to multiple terabytes, more than a million-fold increase.

Today's 2.5- and 3.5-inch drives mainly use SATA interfaces (at least on most PCs and Macs), though many high-speed internal SSDs now use the faster PCI Express interface instead. But each essentially does the same thing: connect the hard drive to the PC's motherboard so your data can be shuttled to and fro.

The internal cable interface has changed over the years from serial to IDE (now frequently called Parallel ATA, or PATA) to SCSI to Serial ATA (SATA). The PC hard drive form factor standardized at 5.25 inches in the early 1980s, with the now-familiar 3.5-inch desktop-class and 2.5-inch notebook-class drives coming soon thereafter. The RAMAC 350 was limited to government and industrial uses, and it was obsolete by 1969. This, of course, is the size of an average 128Kbps MP3 file today, stored in the physical space that could hold two commercial refrigerators. There are well-known photosВ of the IBM 650 RAMAC hard driveВ from 1956 that used 50 24-inch-wide platters to hold a whopping 3.75MB of storage space. Hard drive technology is relatively ancient (in terms of computer history, anyway).

External drives come in both large desktop and compact portable form factors, and SSDs are gradually becoming a larger part of the external-drive market. Note: We'll be talking primarily about internal drives in this story, but almost everything applies to external drives as well. See our picks for the best M.2 SSDs and get much more info on these multifaceted types of SSDs.) (These board-mounted SSDs use a form factor known as M.2. While they can take the place of traditional 2.5-inch or 3.5-inch hard drive bays, they can also be installed in a PCI Express expansion slot or even be mounted directly on the motherboard, a configuration that's now common in high-end laptops and all-in-ones. Like thumb drives, though, SSDs are often much smaller than HDDs and therefore offer manufacturers more flexibility in designing a PC. ( See our deep-dive guide to SSD jargon.) SSDs are consequently more expensive than USB thumb drives of the same capacities. These flash chips (often dubbed 'NAND') are of a different type than the kind used in USB thumb drives, and are typically faster and more reliable. A read/write head on an arm accesses the data while the platters are spinning.ДЄn SSD performs the same basic function as a hard drive, but data is instead stored on interconnected flash-memory chips that retain the data even when there's no power flowing through them. A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the original Star WarsВ trilogy, or your digital music collection. That is, information on it doesn't 'go away' when you turn off the system, unlike data stored in RAM.

The data transfer rate is a high-speed 6GB/s and for complete specs click on the download tab. You can feel confident that by having one of these hard drives in your security system you will be able to retrieve your data if you ever have to produce your footage to the authorities.

This drive can hold 3,000GB of data and will deliver results time and time again. This is a High Quality and dependable Security Recorder Hard Drive that will prevent any frame loss due to the high standards in the manufacturing process. A typical desktop hard drive cannot handle the constant friction that a high temperature, always-on device such as a DVR delivers. When you own a Security NVR or DVR, you must use a hard drive that is made for surveillance recorders.
