windwithme Posted August 16, 2011 Share Posted August 16, 2011 Solid-State Drive also known as SSD is new PC storage in last 3 years. It owns linear transfer performance and super-fast seek time. The performance is leading HDD obviously. Some users also cannot be used to HDD speed after using SSD for a while. Comparing to 100/80 MB/s old type SSD and 100/100 MB/s HDD booting and opening file, the SSD is still much faster. SSD performance isn’t like HDD unstable dues to inner and outer gaps. Also, SSD seek time is very fast. These 2 points make SSD performance is much faster than HDD. As SSD performance development roadmap, it’s been stuck at 300MB/s for a period.It may cause by SATA2 bandwidth. Since SATA3 becomes popular and Intel chipset support natively, the SSD which is over 300MB/s started to sell since last year. Till this year, you even can see many 400~500 MB/s high speed SSD. The SSD products segment and price are decided by capacity and performance. Intel enters SSD business for long time. It owns own R&D ability for NAND Flash and controller chipset. Previous 2.5” version it uses X25-E/X25-M to distinguish SLC and MLC. After that, it launched MLC entry model, X25-V. SLC structure is better; however, the cost is too high. That’s why you see less and less SLC SSD in the market. In naming, these 2 new SSD product lines change to 320 and 510. First, let’s start with 320 SERIES 160GB. The packing is same as new CPU which all with Intel new logo. Of course, blue is Intel color. The warranty increase to 5 years from 3. It’s good news for users. Accessories 2.5” to 3.5” bay mounting bracket, screws, 4-Pin to SATA power cable and SATA cable. Installation CD, installation guide and sticker.s The outlook is same as G2 34nm X25-M. 320 capacity is 40~600GB which is much bigger than previous version. Controller chip is PC29AS210BA0. MLC NAND FLASH is 29F16B08CCMEI, total 12 chips and cache buffer is 64MB. 320 series is 25nm and model change to G3. The max capacity is 600GB. 160GB official spec is reading 270 MB/s and writing 165 MB/s. 4K reading is 39000 IOPS and 4K writing is 21000 IOPS. As SSD capacity is getting bigger, the performance is also improved. Backside is metal texture. If it has polishing, the quality will be better. Upper-Right golden finger is SATA and power connector. It supports SATA2 which is reasonable for 320 SERIES performance. Another model is 510 SERIES which has 120GB and 250GB. The shell is different with Intel other SSD product. The controller IC is 0Marvell 88SS9174. MLC NAND FLASH is 29F64G08CAMDD, total 16 ICs, and cache buffer is 128MB. The accessories are same as 320 series. The only difference is 510 using black SATA cable. Official warranty is 3 years, which is different with 320SERIES. I hope it can extend to 5 years in the future. Backside and front side are the same. Lower-Left is SATA and power connector. It supports SATA3. 510 120GB official spec, SATA2/SATA3 reading are 265/450 MB/s and writing are 200/210 MB/s. 4K reading is 38000 IOPS and 4K writing is 14000 IOPS. 510 SSD bigger capacities have better performance. Desktop PC platform uses GIGABYTE Z68MX-UD2H. Z68 is Intel latest Sandy Bridge chipset. I use it to test SATA performance. Z68 owns P67 OC and H67 built-in GPU simultaneously. Chipset native support SATA3 and all MB makers use other chip to support USB3.0 and other latest technology. Quote Link to comment Share on other sites More sharing options...
