When Did SSD come out?

For years, the hard drive has been the standard for most computers. However, a new technology called ssd is on its way to take over even more market share in the future.

SanDisk Corporation announced SSD back in 1997 and began selling ssd by 1999. This innovation was a huge advancement from the old school hard drive because SSD had no moving parts.

In terms of industry-standard, SSD became available in 2007 with OCZ’s Core Series SSDs designed specifically for mainstream computing needs such as gaming, multimedia creation, and general productivity applications.

According to an article by Wikipedia, SSD technology has been able to reach speeds up to 500MB/s which is exponentially faster than a normal hard drive which only touches speeds up to 100MB/s.

SSD has changed the way computer technology works in multiple ways and ssd is currently on its way to replace hard drives altogether very soon.

SSD Speed and HDD Speed

First off, speed. What does SSD speed have to do with HDD speed? Well, SSD’s are primarily storage devices as opposed to hard drives which tend to be primarily data transfer devices.

Because SSD’s store information without any moving parts inside them, they can access their memory hundreds of times faster than HDD’s which store data on spinning platters.

It’s like the difference between reading information off of a CD and reading information off of a record player.

The SSD reads memory at around 500-600 MB/s whereas HDD’s read data at around 100-150 MB/s, so SSD’s are considerably faster than HDD’s in terms of speed.

The storage capacity of an HDD depends on its platters which can be anywhere from 40 to 500 GB per disk, while there is no limit to SSDS in terms of storage capacity apart from its budget and your willingness.

SSDs cannot overwrite data once it has been written like HDDs do because there will be a risk to lose the already existing data in case you need more space, so they always work read-only, so they don’t get corrupted by themselves. On the other hand, HDDs have moving parts which makes them more vulnerable to failure.

The minimum number of write cycles of an HDD is around 400 TB, whereas it’s around 100 PB for .SSDS

Hence, this makes SSDs more reliable and faster than HDDs with less chance of failure.

Best Cheap SSDs

If you are going to put HDD in the dust bin then please take a look at some cheap SSDs options. Samsung SSDs perform really well than other brands but they are more expensive.

If you are looking for some cheaper options then SanDisk, ADATA, Crucial are the best brands to go for otherwise in something better and get a Samsung 256GB Evo SSD.

I have personally upgraded my old i5 computer to an SSD and I can feel it is almost 15x faster and I don’t have to wait for 1 minute to boot up my computer.

It gives extra boost to my pc performance and As a developer, I would prefer using 8GB ram with at least 256GB SSD.

Now, you might be wondering that why I don’t recommend 128GB SSD and also they don’t have any moving parts like 256GB. The reason is their cache memory is very low and your computer will not run much faster on 128GB SSD compare to 256GB SSD. So, buy at least 256GB SSD.

What is SSD cache memory?

The ssd cache memory in modern SSD s (solid-state drive) to improve performance by serving as an intermediary between the ssd and information stored on disk, or sata hard drives.

Some models of ssd rely solely on caching for all reads, while other models allow the user to disable caching for higher performance at a cost of lower overall ssd life span.

How does ssd cache memory work?

In order to better understand how an SSD’s cache functions, one must first know what happens during a read from a SATA drive. SATA drives get power from your computer via SATA cables.

SATA cables have power pins and sata data pins. Power is supplied to the SATA drive, which the ssd helps the SATA drive receive via additional SSD’s supply voltage to any sata power pin that does not have power.

Once this happens, the SSD enables communication between the sata drive and your computer via its SATA data pins. This communication uses a protocol called AHCI (Advanced Host Controller Interface).

AHCI controls how information is transferred back and forth between an SSD and a host processor, more commonly known as your computer’s motherboard.

There is another protocol called SCSI (Small Computer System Interface) that manages more advanced information transfers like those used by servers or workstations.

Sata drives use ssd cache memory to transfer information. ssd cache reads are significantly faster than sata drive reads because ssd cache memory has no moving parts, unlike sata drives which have spinning disks.

How does ssd cache improve performance?

A pure SSD does not have any SATA interface, only the ability to connect via usb cable or m2 connection.

Pure SSD’s that are used in cellphones use usb cable connections because traditional hard drive bays do not fit into a phone well and take up too much space.

Pc gamers that want better fps (frames per second) and load times often buy dedicated ssd’s like the Plextor M5 pro line (m512g).

Anandtech benchmarks show ssd cache memory increases ssd performance between 30% and 200%, depending on sata ssds.

Wrapping up

Cache is a cache for reads, not writes. If you need to transfer large pieces of data then it will be limited in speed by the sata connection rather than your ssd.

SATA connections are slower than pcie or usb3 connections when transferring larger pieces of data. sata 3 transfers at 6gb/s theoretical while pcie 3 x4 transfers at 9 gb/s theoretical.

A pure ssd helps with random read speeds which benefit certain programs like games where different parts of the game are located in different places on your hard drive, especially program do heavy file swapping during load times.

SSD cache memory is located on the ssd as well so it does not need to access your regular sata connection which will speed up load times and improve I/O performance for gaming and other applications that can benefit from ssd caching.
