The X25-M SSD The Intel X25-M was a line of Serial ATA interface solid-state drives (or SSDs) developed by Intel for personal computers , announced in late 2008. The SSD was a multi-level-cell solid-state drive available in a 2.5" form factor , came in 80 GB and 160 GB capacities and utilized NAND flash memory on a 50 nm process.
In March of that same year, Intel entered the budget SSD segment with its X25-V drives with an initial capacity of 40 GB. [11] The SSD 310, Intel's first mSATA drive was released in December 2010, providing X25-M G2 performance in a much smaller package. [12] [13] March 2011 saw the introduction of two new SSD lines from Intel.
S.M.A.R.T. drives may offer a number of self-tests: [104] [105] [106] Short Checks the electrical and mechanical performance as well as the read performance of the disk. Electrical tests might include a test of buffer RAM, a read/write circuitry test, or a test of the read/write head elements. Mechanical test includes seeking and servo on data ...
The SATADIMM from Viking Technology uses an empty DDR3 DIMM slot on the motherboard to provide power to the SSD with a separate SATA connector to provide the data connection back to the computer. The result is an easy-to-install SSD with a capacity equal to drives that typically take a full 2.5-inch drive bay. [104]
Intel X25-E G1 has around 3 times higher IOPS compared to the Intel X25-M G2. [16] G.Skill Phoenix Pro SSD ~20,000 IOPS [17] SATA 3 Gbit/s SandForce-1200 based SSD drives with enhanced firmware, states up to 50,000 IOPS, but benchmarking shows for this particular drive ~25,000 IOPS for random read and ~15,000 IOPS for random write.

Flash-based storage does not suffer the limitation of a battery, but RAM-backed storage is faster and does not experience write amplification. [ 3 ] [ 8 ] [ 9 ] As a result of having no moving mechanical parts, solid-state storage has no data access latency required to move the media as in an electromechanical storage device.
Like most other electronic storage, flash memory is assembled in powers of two, so calculating the physical capacity of an SSD would be based on 1,073,741,824 (= 2 30) per binary GB or GiB. The difference between these two values is 7.37% (= (2 30 − 10 9 ) / 10 9 × 100%).
