Samsung 32GB Solid State Drive - Samsung 32GB Solid State Drive
As well as these performance benefits, the lack of moving parts used in SSDs means they are extremely resilient. Operating temperatures start at -25 degrees Celsius and go all the way up to +85 degrees Celsius. HDDs, on the other hand, are limited to a range of +5 degrees Celsius to +60 degrees Celsius. Also, the MCAQE32G5APP-0XA can withstand impacts of a colossal 1000g as opposed to a hard drive that will fail with a knock of 70g while operating and 300g while turned off. All of which makes SSDs rather an attractive prospect.
SSDs do have one Achilles heel, though, sustained read and writes speeds can't yet compete with those of HDDs. So, if a hard disk has its data organised properly and doesn't have to do a lot of seeking (moving the read write head back and forth), it will outperform an SSD.
Arranging a pair of these SSDs in a RAID-0 configuration would double the overall read/write speed, making them very competitive with even the fastest of HDDs. However, because the MCAQE32G5APP-0XA uses an EIDE connection, a dedicated IDE RAID card would need to be purchased to enable this - and obviously you can't do this in laptop. If the connection were SATA, you would be able to use the SATA RAID controllers found on most modern motherboards.
Also, EIDE is an old connection so most new laptops don't use it. This made testing rather difficult as we couldn't use a current notebook to test performance and battery life. Therefore we used a desktop test bed to measure the drive's performance. As we were using a full size test bed we thought it would be interesting to include performance figures for a full size desktop hard drive as well as a 2.5in HDD. The two drives I've chosen for comparison are the Hitachi Deskstar 7K1000 and the Samsung HM250JI. The Hitachi has incredibly fast sustained read speeds and equally impressive burst read speeds so it should really give the SSD a run for its money. The HM250JI is one of the largest 2.5in HDDs currently available and gives a good performance comparison for the SSD.
Our test bed consists of an Intel 975XBX2 “Bad Axe” motherboard loaded with an Intel Core 2 Duo QX6800 quad core CPU coupled with 2GB of Corsair CMX1024-6400C3 running at 800MHz with latency settings of 3-4-3-9.
