The Toshiba Q Series HDTS225XZSTA 256GB SATA III Internal Solid State Drive is priced at $149.99. The deal includes free shipping. However, Newegg charges sales tax in California, Tennessee, and New Jersey. Once agin, this is 48 hour pricing, and the deal does not require a coupon code or rebate.
However, Newegg is not the only site selling this drive for under $150. Amazon.com has the same drive on sale for the same price. Like Newegg, Amazon.com charges sales tax in many locations, but this derive is available with Amazon Prime free two-day, lower-cost one-day shipping and Amazon.com has a very liberal return policy.
A decision between the two deals may come down to which state you live in (in terms of sales tax) and whether or not you have Amazon Prime.
This SSD uses Toshiba's 19nm Toggle-Mode 2.0 MLC NAND and a Marvell controller. It is rated at a Max Sequential Read of up to 552MB/s and a Max Sequential Write of up to 501MB/s.
SSDs are, of course, far faster than standard mechanical hard drives, which must reposition a magnetic head in order to read data. None of that is necessary with an SSD, but there are other issues, instead. What has kept adoption down, until now, has been the cost of SSDs. For example, a 2TB, not GB, standard hard drive can be found for about the same price at Amazon.com, and that would be for a drive that runs at 7,200rpm, not 5,400rpm as some lower cost hard drives do.
Due to the cost isseus, at this point, many use an SSD as a boot drive, and then add a secondary large capacity hard drive for storage of data and perhaps lower priority programs that they run less frequently. An SSD is essentially flash storage in the form of a drive, and tablets and smartphones use them as well as laptops and computers.
SSDs should never be defragmented, though trim is a necessary function. TRIM marks blocks of data which are no in use, indicating to the drive controller and the OS (assuming it supports it, as Windows XP -- for examplel -- does not) that the blocks can be wiped. Windows 7 and up supports this function.
TRIM is necessary because an SSD has no access to the file system structures of an OS. In the "good old days," delete operations were typically limited to flagging data blocks as "not in use" in the file system. However, for SSDs, the TRIM command must be sent to the drive to indicate to it that those blocks are no longer being used.
Interesting? Perhaps not, but it is important that a drive and OS support TRIM.
